[rotund perch]

try putting

/ in the last

..../create-question/

[nova sonnet]

that doesnt work

let me try and change the action first

[eternal blade]

I have Django-cors-headers and allowed hosts

[rotund perch]

CSRF Cookies? Decorators?

if none then sorry I dont know what would the solution be.

[eternal blade]

I am using a class based view

[rotund perch]

okay, did u include the JS CSRF Cookie function?

[eternal blade]

Thanks for trying to help

[eternal blade]

I am using a python script to test the api

[rotund perch]

np, I hope u find a solution asap good luck!

[eternal blade]

🙂

[opaque rivet]

what's the problem?

[dense slate]

any luck?

[nova sonnet]

need a way to pass into the community id into the template so im gonna pass it as context

[dense slate]

Great

[nova sonnet]

it doesjnt work

[dense slate]

You added the path to the view?

Share some code and we can look over it.

the form and the view

Show the whole form,

the view, and the full url/path

See you're cutting stuff off with screenshots. It's better to paste actual code.

But post your view as well, where you handle the post request.

[nova sonnet]

yeah my bad

im doin something atm so im rushing

[dense slate]

No worries, we can look at it later.

[nova sonnet]

thats the view

[dense slate]

Did you try printing in it to see if you're even calling the function?

[nova sonnet]

its not being called and im not sure why and yeayh

[dense slate]

Where did you put the print statement?

[nova sonnet]

on the top of the method

[dense slate]

Show me where, I don't know what on top means.

[nova sonnet]

the form_valid one

right beneath it

[dense slate]

put one as the first line in the class

and then submit the form, do you get anything printing in the terminal?

and I assume you're logged in?

[nova sonnet]

yeah

the thing is nothing is being calledf

the print doesnt work and ive moved it

[dense slate]

what happens if you remove the action= from the form all together and then submit?

[nova sonnet]

ive used the createview in other instances and the action wasnt even needed

[nova sonnet]

same thing happens

[dense slate]

Yea it's not necessary.

But now that you've actually hard-coded it, and it still doesn't get into the function, means you have something obviously not making that connection, and my guess is something isn't written correctly. Is that url called 'create-question' at the end?

[nova sonnet]

yeah

[dense slate]

oh

you have community spelled incorrectly, if that matters

in your url/path

[nova sonnet]

oh dang

let me check it now

[dense slate]

why do you have a pk in the create question path?

what's the pk related to?

[nova sonnet]

the community the question is going to be added in

fixed the typo but no change :((

[dense slate]

post your urls.py @nova sonnet

[nocturne basalt]

Can you explain what a meta class do?

[dense slate]

the whole thing

and the url that's in your browser on that page

[barren sable]

I am rendering http content on a https page, therefore getting the mixed-content error. I have searched on web what solutions there are for this issue and for now I have chosen to create a proxy server that uses https and will forward the request. If you know a better way except not using http let me know. I am not using https because I cannot change that system.
I am rendering images on my website this way.

<img src="http://image.com/image/12" />

I am wondering if it is possible to use the proxy inside src attribute. Something like

<img src="https://someproxy.com/http://image.com/image/12" />

I am using django and I could also try to make the request in python and send the image to the dom. But since I have already configured the proxy I want to try using it inside src attribute.

[nova sonnet]

http://127.0.0.1:8000/commuinity/2/create-question/

[dense slate]

it's misspelled again, are you making the changes?

[nova sonnet]

yeah just had to clear the cache

yet it aint working

[dense slate]

It might have something to do with the 'community/<int:pk>/create-question/ and 'community/<int:pk> urls

Do they all need / at the end?

But then you wouldn't see the page either... 🤔

[nova sonnet]

yeah i added it when the other guy told me to

[dense slate]

but not to all of them

[nova sonnet]

i have no idea why the view just doesnt want to work

[manic hearth]

Hi Guys

I want to do something like that

using django rest framework

can anyone help me?

[nova sonnet]

I fixed it, the reason why it wasnt being called is because the form data wasnt validated lmao

[dense slate]

What did you add?

[dense slate]

That is just a json object. You don't "do" that. It's just an object. What is it you want to do?

You can, for example, return a json object via DRF but that's very general and you would need to share what you're trying to accomplish.

[native tide]

hello why i get this error: ImportError: cannot import name 'Oauth' from 'oauth' i just copied swastik

[nova sonnet]

Just had to get rid of the fields I wasn’t displaying on my template on the model form

Everytime I was submitting they were being left out so it wasn’t being validated

[vital crest]

hey guys

im writing an API i should use which name formatting??

camel case right??

[dense slate]

I think that depends. In graphene you query with camel but backend is still lowercase with _'s

how to use ajax in django

[tough crane]

Quick stupid question I didn't find an answer to, but is it possible to link an image in css / scss file that is online? Or do I have to have them localy? nvm I just had a typo. fml

[opaque rivet]

@eternal blade what are your DEFAULT_AUTHENTICATION_CLASSES in settings.py?

My guess is you have some middleware requiring a token.

[eternal blade]

knox.auth.TokenAuthentication

[opaque rivet]

So that means that all your views have the knox.auth.TokenAuthentication middleware which requires a token, I'd find a way to take that off your LoginAPI view

[eternal blade]

Thanks, I'll try to do that

[opaque rivet]

Are HTTP requests between docker containers SSL secured?

[green prairie]

Does anybody have any good resources on modern web design? (Not web development, but actually designing beautiful websites)

[inland oak]

I doubt it

with 90% there is no SSL in between

unless you set it on your own

[worthy lake]

yeah, thats a complicated question. Design and development are not really the same things. I know that when I have design questions, I take them here https://discord.gg/srhkZ52w

[green prairie]

Perfect - Thanks a lot! I'll check it out 🙂

[inland oak]

you have in general several options
setting reverse proxy with attached even unverified certificates I think

or you could use something like this, I was advised to try it at least
https://www.stunnel.org/

or you could just enable firewall ;b

I went so far with firewall option

[opaque rivet]

Ah, thanks, not looking to do it just wondering.

[inland oak]

beware, UFW firewall is not working for docker 😉 due to some conflict in records

but iptables works

hey guys, how can I make it so that when I close the sidebar, the elements on the white background must occupy the area of sidebar and when I close it, do the opposite...

[fossil pond]

Hey can we ask HTML and JS queries here?

[native tide]

no they need to run in a browser

i think you can get bots to render html. not sure about js

that was a joke btw

[rotund perch]

Hello, is there a way to unregister Token from the admin dashboard the Token im using is from rest_framework.authtoken.models import Token.
When I try to register it in the admin it displays two Token tables

[manic frost]

yes

[fossil pond]

thanks I'll!

[west arrow]

If you're not using models for your rest API is it possible to do a put request for your dictionary? I'm new to this, I'm trying to do it but it doesn't work.

https://paste.pythondiscord.com/asorileqov.py

[eternal blade]

Do you know any way I can do this? I tried using knox.views.LoginView but I still got a status of 401.

[tulip beacon]

guys anyone?

[glacial yoke]

If I have a function in django views.py, how can I call that function in my react frontend app, when for example pressing a button, which is displayed on the website?

[opaque rivet]

@glacial yoke you're looking at making an API endpoint and making http requests to it from your frontend.

[glacial yoke]

by api endpoint, do you mean an APIview?

and also, how could I make an http request to one?

[opaque rivet]

@eternal blade I'm on my phone, but what I can tell you is that authentication class is default so it affects all views.

@glacial yoke You can use JS. A request lib like axios to send http requests.

[glacial yoke]

Yeah, I've tried using axios, but how exactly should I send the request?

[eternal blade]

So should I remove knox.auth.TokenAuthentication from the settings.py and then make all classes (except the LoginAPI) inherit from knox.auth.TokenAuthentication

[glacial yoke]

I've tried something like this:

function login(){
    const response = axios.get("/login")
}

But then how do I call it?

[opaque rivet]

@eternal blade yes, maybe it has some docs on how to set the authentication class on a view.

[eternal blade]

Thanks

[opaque rivet]

@eternal blade https://james1345.github.io/django-rest-knox/auth/

Here is an example for how to set the authentication / permission classes on a view

[eternal blade]

Thanks

[opaque rivet]

@glacial yoke axios.get returns a promise. To access the response you can await it or have a .then() block

[glacial yoke]

and then, would I just stick the function into a button, and it should work, right?

and also, can you please show me an example of a proper api view, because I'm not too sure how to set it up

[pearl quiver]

hello, I have a question regarding FLASK.
My FLASK application sometimes has to process a folder of files, and I would like an update to come back as they're finished.
But right now, it's like:
@app.route('/processfiles'): def processfile(): for x in dirname: process_file(x) return "status text"

and that status text doesn't get returned until everything is finished

is there a term I can google to get more information ?

[dense slate]

What kind of update?

[pearl quiver]

so let's say i'm processing 100 files ... ideally i would like output after each file is done. filename and success/failure code

[dense slate]

Just in the terminal?

[pearl quiver]

no, through the browser using FLASK

[dense slate]

You would need to probably handle the for loop on the front end in that case, and print something for each thing it iterates over.

return the context/array, and iterate on the front end, printing for each item.

[pearl quiver]

the problem is that FLASK only takes 1 return, and that return gets put on the page

i could be wrong because i'm new at this 🤔

[dense slate]

Hmm, Is see what you mean... I'll have to think about it.

Maybe handle it like a % done indicator?

[pearl quiver]

I can do it in the terminal no problem

it's getting it to do it in the browser i'm having trouble with 😅

[dense slate]

Yea, so I would probably look into how to setup a % status complete indicator on the front-end.

And just print "done" instead of changing the %.

[pearl quiver]

great, thanks! I'll take a look

[dense slate]

How long does it take to process the folder?

[pearl quiver]

it depends on the time of the month but between 10-20 mins

there are a bunch of excel sheets to lift info off of and screenshots to be made

it's for a local application, so requirements aren't high

but people get suspicious when the page just says "loading" for that long 🤣

[dense slate]

https://buildwithdjango.com/blog/post/celery-progress-bars/

This looks about what you need.

[pearl quiver]

thanks! except I probably can't do celery or redis 😅 but i'll take a look. maybe I just need the idea
it's cuz we're on windows because of Excel

[warm goblet]

Hello..I want to learn django..but since moat of the tutorials are on django 2 ..what should i do

[glacial yoke]

there isn't much difference between django 2 and 3, and also, django 2.2 is still going to be well in support until the end of 2022

[warm goblet]

Thanks @glacial yoke ...

[dense slate]

There are tons of Django 3 tutorials - and they are essentially the same. There are changes for D3 - mainly async if you want to use that - but the major changes aren't necessary for core features.

[warm goblet]

Thanks @dense slate .

[fast lava]

hello

does anyone know django

#help-bagel

Pls help me here

[nova sonnet]

for django is there a way to pair contexts? im iterating a qs with users and im trying to get a count of related objects using a filter

[rotund perch]

u mean u want to count the objects that is returned after filtering it?

[nova sonnet]

I want to count all of the objects set for that user

but i want to filter that objects set

[native tide]

I'm trying to decide on Django REST framework or FastAPI for my backend for a new project I want to work on. Anyone have any suggestions or experience with either of those?

[rotund perch]

try
Model.objects.filter(..).count()

[nova sonnet]

is there a way of getting a count through the user though?

[nova sonnet]

because im iterating through a user qs

[rotund perch]

for user in users?

[nova sonnet]

yeah i have a user qs, and im displaying a list of users, i want to show a count for all of the objects set for that specific user with a few filters on too

[rotund perch]

for user in users:
   objects = user.objects.all()
return objects.count()

something like this? btw I am just trying to help you with how I understand what you said, sorry if I did not understand you well

[nova sonnet]

Don’t worry I appreciate it :)), so I’m iterating the user query set on the template not on the view

[rotund perch]

if its correct, just replace it with the blocks

[tawny pollen]

hello I have a django question

[rotund perch]

{{ }} & {% %}

[tawny pollen]

def forms(request):
    inital_dict={
        "text": "Some initial data",
        "integer": 123,
    }
    form = TestForm(request.POST or None,initial=inital_dict)
    data = "None"
    text= "None"
    if form.is_valid():
        data = form.cleaned_data
        text= form.cleaned_data.get("text")
    return render(request,'first_app/forms.html', {'form': form,'data': data, 'text': text})

is it okay to remove "or None" inside TestForm?

[nova sonnet]

Yeah like that I’m trying to figure out how I can get a count of all related objects through the template or if I can pass it as another object but still have it related to that specific user

[rotund perch]

in the view

objects = None
for user in users:
  objects = user.objects.all()
number = objects.count()
return render(request,'template.html',{'number':number})

in the template

<h1>{{ number }}</h1>

NOTE: I didnt try it

[nova sonnet]

im using a class based view, and im passing in 'users = user.objects.all()' as context right, now i want all of the related objects with additional filters on it, for eg, 'users.modela_set.filter(fk = 2)' and pass that in and make it match the correct user

[nova sonnet]

do you get what im trying to do?

[rotund perch]

but who is the correct user? are u trying to get him with id or?

[nova sonnet]

im iterating through a list of users and they all have objects related to them

so they are linked through an fk

[rotund perch]

oh u mean u want the user who matches the fk of other models?

[nova sonnet]

kinda and i need to display the list of each user and data that relates to them

[rotund perch]

is it one fk ? or multiple

[glacial yoke]

I've got a login system using django social auth app, and it has it's own integrated sessions and etc.
I'm trying to make a function which would find out if the user is logged in or not, can someone help me with that?

[rotund perch]

u arent using tokens?

[glacial yoke]

nope

I don't really need to, because if a user is logged in, they'll just have a permanent session

until they log out of course

[rotund perch]

def my_func(request):
    if request.user.is_authenticated():
        print ("Logged in")

or

from django.contrib.auth.decorators import login_required

@login_required
....

I Hope thats what u were looking for

[glacial yoke]

Thank you very much

I’ve been looking for this for the past 2 or so hours

[rotund perch]

np

[glacial yoke]

Btw, how could I request this function from react front end, for example if I wanted to render the log in button if the user isn’t login, but if he is, I would render the logout button

Would I have to create an apiview?

[rotund perch]

You will need an api url.
Ive never used Sessions with an api so im not sure if it works correctly, u will need Token based authentication.
Then if the user has a Token with him that means he is logged in, else he is not.

[glacial yoke]

So I would have to setup a jwt token system?

[rotund perch]

u have more than one option, there is also basic token & I think that will be easier for u as a first time

[glacial yoke]

yeah, but jwt is probably easier to manage, especially using DRF

[odd nova]

hii
this question is a bit more about electron but I think I can ask it here?
I wanted to call a function in a .py file using electron, without having to use stdout, stdin, etc
is that possible?
I only found stuff about python-shell so far, which doesnt fit my requirements...

[rotund perch]

okay if that is what u are comfortable with. I think jwt tokens generates a new token for every log in, so u will need to take the token from the login response in react

[rotund perch]

what does the function return?

[glacial yoke]

yeah, but if they log in, their session should be permanent as long as they don't log out, right?

[rotund perch]

I think u can also set a timer for the token

[glacial yoke]

ok, I need it to be permanent, so it's fine

[dense slate]

Permanent tokens aren't safe so make sure you're not doing that in a sensitive app.

[odd nova]

an array with dictionaries in it
I just dont want to use stdout and stdin

specificly
I dont want to change the function

[rotund perch]

okay how do u want to call the function? u want to see the array or access it?

[odd nova]

acess it
my idea is to use the data that the python function returns to me to build the page

well
i mean

whatever
if it returns only text of the result i can use it as json, right?

i just havent found how to get anything from it

[rotund perch]

u can convert it to a JSON object instead of making it an array

but idk how electron works tbh, is there a way to import files?

[rotund perch]

wanted to ask since u mentioned that, are basic tokens safe enough? they are stored in the db and are permanent unless logged out

[dense slate]

Tokens are generally stored in cookies. How are you using them in the DB?

[broken mulch]

Hello guys if my frontend is React how would I store tokens generated from backend? I can’t even see HTTP headers

localStorage and document.cookie doesn’t seem to be very secure

[rotund perch]

rest_framework.authtoken

[broken mulch]

And about WWW-Authenticate response header, how would I do that in frontend React?

[rotund perch]

Try axios

[broken mulch]

How

Axios.get to backend?

[rotund perch]

No its a react library

[broken mulch]

Then backend respond with WWW-Authenticate

[broken mulch]

No it’s a NPM library

And I usually use fetch

[rotund perch]

U will get response data and take token from it

[broken mulch]

I can get token but how do I store it

In user’s browser

I cannot make httpOnly cookies

[rotund perch]

idk that sorry

[broken mulch]

Nor use Authentication

Unless I use a template rendering tool which I am not planning to

Since I’m using React-router-dom

[dense slate]

Generally I mean. Tokens are typically created on the front-end with a time limit with refresh token saved in the DB.

If you just have a permanent token, why not just use sessions with django auth?

[dense slate]

Why can't you?

That's the way you should be storing them, as httpOnly cookies.

[odd nova]

Nevermind that

I will use a separate file
That once runned
Will get a specific module and function
Using the string values passed by this system
That is a good enough workaround my issue I guess

[broken mulch]

I can’t access httpOnly cookies in React can I?

[opaque rivet]

you can't access httpOnly cookies with JS as they do not appear in document.cookie. You can set these cookies from your response - include a Set-Cookie header in the response to set a cookie and you can make it httpOnly, read the docs on that.

[broken mulch]

Like login session

How do I remember a user

I’m going to host my website on netlify so my backend would just act as a database and REST API

[broken mulch]

I know how to make httpOnly cookies I just need to access the user token in frontend while also making it as secure as possible

[dense slate]

Yea you can.

Oh access them.

[broken mulch]

Do U mind linking the docs for that?

I need a secure way to store login sessions

[dense slate]

I set the access token in state, and then use an httpOnly refresh token to refresh it upon refresh or opening a new window.

[broken mulch]

Hmm

[dense slate]

After each refreshToken is used, you set it to invalid in the DB and assign a new one.

[broken mulch]

I don’t really understand can u map it?

[dense slate]

When a user logs in, return the access token to React and set it in state.

Along with sending an httpOnly refresh token into a cookie.

Use the access token until it expires or state is cleared, such as on a refresh.

When the access token is invalid in that case, use the refreshToken to silently grab a new token and reset the state.

[broken mulch]

Yes

[dense slate]

and repeat as necessary.

[dense slate]

That help?

[broken mulch]

How do I know refresh Token in React then

[opaque rivet]

damn, why can't you just save it as a non-http cookie? 😂

[broken mulch]

If the state is reset

[dense slate]

You grab it on the backend.

[opaque rivet]

sounds complicated

[broken mulch]

How do I verify it’s the user’s browser?

[dense slate]

Wait no, sorry. I use django-jwt to run a functionin React to run a refresh command on the backend. That function grabs the token from the browser.

[broken mulch]

I see

[dense slate]

The refreshtoken is saved in the DB

so it validates it against that

when it uses it, it invalidates it and sets a new one in the DB

[broken mulch]

How does Django-jwt run a function in React

[dense slate]

that last part to invalidate is just extra security.

I don't know, the library handles that. 😄

[broken mulch]

kk

I’ll check it out

token-security-conversation

^^^ ignore that I just need that to control-search later

[dense slate]

It took me like two weeks to wrap my head around it and get it working, but now that I understand it, it's pretty easy to setup.

[nova sonnet]

hey is there a good way to get a count of all related prefetched objects?

[dense slate]

backend?

on the query?

Query.objects.count()?

[nova sonnet]

I wanna display it on the template

[dense slate]

qcount = Query.objects.count()
return render("page", {"qcount": qcount})

[fossil pond]

Hey guys. I wanted to make a Django website where the window is divided into two divs of equal size. The left side has links and the right side has an image. When I hover over any link the image should change on the right as per the link without the page reloading. The images and the links would be dynamically added from the backend using models. Is that possible?

[dense slate]

Then use qcount in the template.

[dense slate]

That sounds like fetching all the objects up front and then affecting what the window displays with css.

[fossil pond]

Yeah. Can it be done using models?

[dense slate]

What do you mean done with models?

[fossil pond]

Basically if I have to add new content, I could do so from the admin panel.

By new content I mean link and image

[nova sonnet]

Im displaying a list of users within a group, and i wanna display the count of objects related to that user and group

[dense slate]

Yea, so did I answer your question above?

[dense slate]

Yea that's fine... you need to query all the objects in the table and return them to your template. When you add a new item in the DB via the admin panel, that will automatically be fetched in future queries.

[fossil pond]

Thank you very much, I shall do that!

[nova sonnet]

problem is it displays the count of all objects instead of objects related to that group

[dense slate]

So you need to query the right thing first, and just add .count() on the end

So filter the query to get the stuff you need.

query.objects.filter(group="correct_group").count()

[nova sonnet]

aight, how could i then match the count to the correct user?

because i want to display a list of users and a count next to each user

[dense slate]

What exactly are you counting?

[dense slate]

Elaborate on this.

[broken mulch]

https://media.discordapp.net/attachments/434487580130803712/881735872809173002/unknown.png

Anyone good in CSS know why this is happening?

When I change overflow-y to scroll it just does that

The middle row is the exact size of the container div if that helps

this is the container div:

.rightSlide {
    overflow-y: scroll;
    position: absolute;
    display: flex;
    flex-direction: column;
    height: 100vh;
    width: 6vw;
    margin-left: 85vw;
    margin-right: 2.5vw;
    justify-content: flex-start;
    align-items: center;
    -ms-overflow-style: none;
    scrollbar-width: none;
}

[nova sonnet]

there is a m2m relationship between my users model and custom group model, I have a page listing all of the users within a certain custom group, I also have objects such as 'questions' that are linked to the custom groups and users, how can i get a count off all of the 'questions' that are linked to the user and group

[dense slate]

Btw, you can also {{ qobject.count }} in the template

if that helps

[broken mulch]

this is react-calendar

.rightSlide .react-calendar {
    position: absolute;
    margin-top: 25vh;
    background-color: gray;
    color: white;
    border-radius: 10px;
    padding: 10px;
    width: 20vw;
    height: auto;
}

I tried z-index but that’s not the issue

[dense slate]

https://stackoverflow.com/questions/3395863/how-can-i-get-the-object-count-for-a-model-in-djangos-templates/10008017

[glacial yoke]

this is refering to my old so called problem
so I've set up a social authentication in my django app, and whenever someone logs in a jwt token is made to manage their session
firstly, how can I refresh this token, if it expires when the user is active
and secondly how can I check on my react frontend if the user is signed in or not, would I just check if the jwt token equals to none, but how exactly would i be able to refer to this session, because I can't really refer to a user, because he is "anonymous", because he is not logged in yet

[dense slate]

This might have your answer.

[nova sonnet]

I've tried that, even though it gets a count for a specific user, it doesnt take into account if it is linked to the same group or not so it gets a count for every single 'question' for that user

[nova sonnet]

aight ill have a lookj

[nova sonnet]

it gets the count of every object for that user instead of every object for that user and group :((

Hi

I need website for my startup

Bitesys.com

[dense slate]

I just can't quite picture what you want to show.

You have a list of users.

You want to count the questions that belong to both the user and the current group and show it?

[nova sonnet]

correct

[dense slate]

So like... Questions.objects.filter("user"=user).filter("group"=group).count()?

I'd have to see your models i think.

[nova sonnet]

well to display the users i got community.users.all()

[dense slate]

oh yea ok, show your models

[nova sonnet]

what part would you like to see?

[dense slate]

You're probably going to be best off doing something like adding a method to your model class where you pass the user and group ids into the method and then in that method query the questions where user and group equal those ids. Then in the template, make a for loop that runs that method for each user in the group.

That make sense?

[nova sonnet]

hmmm

can you give an example

[dense slate]

Give me a moment and I can.

so under your model class, you'll have a method like

def count_stuff(self, user, group):
  qcount = Questions.objects.filter(user=user).filter(group=group)
  return qcount

In the template, you'll make a for loop, and inside of it you'll do {{question.count_stuff}} for each user

(question is the model class name that you returned to the page earlier)

[nova sonnet]

what model would this go under?

[dense slate]

The user

so in the for loop you'll do {{user.count_stuff}}.

Because you originally queried users right? to display?

[nova sonnet]

yeah

so how would it get the group?

[dense slate]

On the page, are you only querying the user or the user and group?

[nova sonnet]

im querying the users through the group

[dense slate]

Show me your queries and how you display them in the page. When I just have bits and pieces I can't give you solid examples.

[nova sonnet]

        community = Community.objects.get(id = self.kwargs['pk'])
        users = community.users.all()
        context['users'] = users
        return context

hopes this helps

thats how im querying the users

[dense slate]

And community is the group?

[nova sonnet]

yeah

[dense slate]

So users is just the users in a particular community already?

[nova sonnet]

no, users and community are m2m

[dense slate]

but you're getting community.users, so users is the set of users in that community, yes?

[nova sonnet]

oh yeah mb read that wrong

[dense slate]

so in the User model, write a function/method that states:

def count_questions(self, community):
  count = Question.objects.filter(author=self).filter(community=community)
  return count

Right? That gets all the questions for those two variables.

in the template:

{% for u in users %}
  {{u.name}}: {{u.count_questions}}
{% endfor %}

that will list the question count for each of those users in that community

so you just have to modify that however you need it

[nova sonnet]

so would author = self, and how would the community get passed into the method?

sorry if im being slow

[dense slate]

Ah right, so that might have to be pulled from the URL. Maybe put request in the method like the above edit and pull the communty id from your URL.

Trying to think of another way but that's the first way that comes to mind.

[nova sonnet]

im able to pass in the request?

[dense slate]

request.GET.get['whatever_variable']

See if you get an error trying it.

[nova sonnet]

how would i implement it in the template though

to pass the request?

[dense slate]

Yea you can't pass that. Hmm I'm trying to think how to get that variable in there.

You might need to create a custom templatetag

[nova sonnet]

yeah i heard about that but i try to avoid it

[dense slate]

But I feel like there's another way. I just can't think of it now. I'll look at it again later.

[nova sonnet]

thanks for your time :))

I'm having a difficult time with my django, can someone help me? I'm getting this error on my front-end

here is my form tags

don't know what went wrong 😩

[toxic hemlock]

hey y'all i'm making a web app in flask and i want to have my log in involve a redirect but i want the redirect to have all the html form info to be invisible in the url of the page the user gets redirected to, i.e. like using POST, but when i do the redirect i end up getting the info in the url. for example, if the user's username is "zeljko", the url will be something like "localhost:5000/dashboard/zeljko". i don't want the "zeljko" to be there, meaning something like "localhost:5000/dashboard" while still having access to the form data. is there any way around this? here's the code with descriptions if it helps:

## /join pulls directly from the method="post" form on login.html, where the user logs in
@app.route("/join", methods=["POST", "GET"])
def join():
    username = request.form.get("username")
    ## basic log in logic, checks if passwords match and if user is verified, etc.
    ## if all matches, then:
    return redirect(url_for("dashboard", username=username))
    ## if not, then:
    message = "Looks like the username and password don't match."
    return render_template("login.html", message=message)

## /join redirects to /dashboard when login is successful
@app.route("/dashboard/<username>", methods=["POST"])
def dashboard():
    username = request.form.get("username")
    return render_template("dashboard.html", message=username)

[toxic hemlock]

nvm i got it lol

i decided to use webpack and babel to bundle and transpile my react frontend, and now I have problems with my project
I get this error when I runserver in django

"GET /main.js HTTP/1.1" 404 4309

this is my webpack.config.js

const path = require("path");
const HtmlWebpackPlugin = require("html-webpack-plugin");

module.exports = {
  entry: path.join(__dirname, "src", "index.js"),
  output: {
    path: path.resolve(__dirname, "./build/static/js"),
  },
  module: {
    rules: [
      {
        test: /\.?jsx$/,
        exclude: /node_modules/,
        use: {
          loader: "babel-loader"
        },
      },
      {
        test: /\.?js$/,
        exclude: /node_modules/,
        use: {
          loader: "babel-loader"
        },
      },
      {
        test: /\.css$/i,
        use: ["style-loader", "css-loader"],
      },
      {
        test: /\.(png|jp(e*)g|svg|gif)$/,
        use: ['file-loader'],
      },
    ],
  },
  plugins: [
    new HtmlWebpackPlugin({
      template: path.join(__dirname, "./build/index.html"),
    }),
  ],
};

this is my babel.config.json

{
    "presets": [
      [
        "@babel/preset-env"
      ],
      "@babel/preset-react"
    ],
    "plugins": ["@babel/plugin-proposal-class-properties"]
  }

these are my dev dependencies in package.json:

},
  "devDependencies": {
    "@babel/core": "^7.15.0",
    "@babel/preset-env": "^7.15.0",
    "@babel/preset-react": "^7.14.5",
    "babel-loader": "^8.2.2",
    "html-webpack-plugin": "^5.3.2",
    "webpack": "^5.51.1",
    "webpack-cli": "^4.8.0",
    "webpack-dev-server": "^4.1.0"
  }

and this is how it manages static files in settings.py:

STATIC_URL = '/static/'

STATIC_ROOT = os.path.join(PROJECT_ROOT, 'static')

STATICFILES_DIRS = [
    os.path.join(PROJECT_ROOT, 'apps/frontend/build/static')
]

[dawn shard]

So I am taking input from users in number. How can I add all and print it on a page?

[neon osprey]

I've got the same issue but with Flutter. +Django

[native tide]

I'm new to networking and working with ESP8266. I have successfully setup my ESP8266 and can program it from Arduino IDE.I want to send some data from a Python script running on my PC to ESP8266. Similar to a setup where use PySerial in Python, open a COM port and send my serial data to an Arduino. Arduino will parse my data bytes and will perform some action. Now, I am trying to achieve the same with ESP8266 and UART replaced with wireless communication.

[glacial yoke]

it used to work perfectly for me, before I installed webpack and babel, and now idk how to get it to work again

[neon osprey]

It's my first time doing a full stack web application and i've got no idea at the moment as to why it's not loading, certainly feel like missing part of the puzzle unless i've overlooked something!

[worthy lake]

These labels for my models... what class and attribute can I change these labels in admin.py?

[heady quail]

This pattern worked in Python for Regex, but lookbehinds like this aren't allowed in JavaScript or something?
How do I convert this into something that works in JavaScript? I don't know JavaScript or Regex well.
The regex is trying to match words beginning with underscores but not words with underscores inside them - works fine in Python.

regex = r'(?<![a-z])_[a-z]*'

Edit: For my purposes it was fine to not do the look behind and just use a character like ![a-z])_[a-z]*

[glacial yoke]

if you fix the problem, can you let me know, please?

[inland oak]

there is literally redirect function
https://docs.djangoproject.com/en/3.2/topics/http/shortcuts/#redirect

[inland oak]

possibly python manage.py collecstatic command is missing or something like that
https://docs.djangoproject.com/en/3.2/howto/deployment/

[glacial yoke]

if I wouldn't have run that, then it wouldn't even grab the static files

Right here the problem is, that it's searching for the static files in localhost:8000/main.js

[inland oak]

why are you trying to access main.js file though

should not it be index.html?

[glacial yoke]

and not just grabbing it from static files

[inland oak]

I thought React built files look like html/css/js files

have you made React build?

[glacial yoke]

I used webpack to bundle the build

So it's literally just an html file and a main.js file

the main.js file is inserted into the html

django can get the html, but for some reason not the main.js

[inland oak]

Right here the problem is, that it's searching for the static files in localhost:8000/main.js
I thought you expected to search at this route

which route you expected to have?

according to your settings

/static/main.js

should be current address of this file probably

if you want your static files served without /static/

change STATIC_URL variable to /

or explain your problem further

[glacial yoke]

ok, this is what's happening

this is how it looks in my frontend app

[inland oak]

right

[glacial yoke]

and this is how it looks in the main directory/static

pretty much, what django does, is it take all the files from the staticfiles dirs, as it's stated in settings, and puts all of them into the main directory/static, which is the static root

and then from there it should display them onto the website

[inland oak]

yes

and what's the problem?

[glacial yoke]

the problem is that it's searching for main.js's directory as localhost:8000/main.js, when quite literally it's not a website directory, so it should search for it in the website files(static files)

[inland oak]

the correct path should be /static/js/main.js for this file

[glacial yoke]

yes

[inland oak]

so... your links in frontend are broken to search main.js at /main.js url

that's your problem?

[glacial yoke]

could be

let me check

<script defer src="main.js"></script>

it looks fine in the html file

[inland oak]

so, you have relative path written here

you access index.html at folder /

relative path searches for the file in / (the same path as /index.html is)

it worked correctly.

https://www.w3schools.com/html/html_filepaths.asp

<img src="picture.jpg"> The "picture.jpg" file is located in the same folder as the current page

if you wish to access the file from /index.html... you have next options:

1. changing path to "js/main.js" | "static/js/main.js" or something like that
2. changing to absolute /static/js/main.js
3. changing static_files in django settings, to collect all statics into one level folder instead of having sub folders (it will lead to collisions for same named files)
4. perhaps there is some webpack/react/frontendframework solution I don't know, like using some special flag during front building

[glacial yoke]

I'm currently working on my small Flask project and I got stuck at some point. I got stuck on Response method because it doesn't work as I expected. When I use it in my code it's available only in 1 tab unless I run it with Gunicorn with more workers and threads, but that's not what I want. I want it to be accessible in multiple tabs with same content. Is there maybe some other method that I should use?

[fast lava]

Hello

Does anyone here know django well

#help-peanut

[thin lance]

you are right about redirect but the problem is that ListView and get_queryset do not allow HTTP methods e.g. response or redirect.

[thin lance]

Thanks for the answer, I found a solution to this with the help of override method

class DeleteContact(ListView):
    model = AdressEntery
    allow_empty = False
    template_name = "main/contact_list.html" 
    context_object_name = "contact"
    def get_queryset(self, *args, **kwargs):
        queryset = super(DeleteContact, self).get_queryset()
        return queryset.filter(id=self.kwargs['pk']).update(active=False)   # filter by clicked contact card get id and set active false
    def dispatch(self,request, *args, **kwargs):   #this method allows us to use methods such as (post, get, put ..) and allows us to return HTTP methods such as (response, redirect)
        super(DeleteContact, self).dispatch(request)  #dispatch method will override the second method and allow us to do redirection
        return redirect('/api/contact-list/')

[fossil pond]

Guys why am I getting redirected to this link: http://127.0.0.1:8000/projects/undefined (to undefined)? I have a file called projects.html and implemented correct redirecting methods.

[manic frost]

Can you show the code?

[fossil pond]

ofc.

views.py:

    return render(response, "projects.html", {})```

urls.py:
```urlpatterns = [
    path("", views.home, name="home"),
    path("projects/", views.projects, name="projects"),

]```

Redirection was working up until I changed the name of the html file

Can I ask here?

[opaque rivet]

@native tide go ahead

[native tide]

I am trying to use Model Form's with class based views but I can't get the submit button to work
Here's my code

my forms.py

from django import forms

from .models import Volunteer


class VolunteerJoinForm(forms.ModelForm):
    class Meta:
        model = Volunteer
        fields = '__all__'

my views.py

from django.http.response import HttpResponse
from django.views.generic.edit import FormView

from .forms import VolunteerJoinForm


class VolunteerJoinFormView(FormView):
    template_name = 'website/join.html'
    form_class = VolunteerJoinForm
    success_url = '/join-success/'

    def form_valid(self, form):
        return HttpResponse('DONE')

my join.html template

{% extends 'website/_base.html' %}
{% block title %}Join Us{% endblock title %}
{% block content %}

    <form method="POST">
        {% csrf_token %}
        {{ form.as_p }}
        <input type="submit">
    </form>

{% endblock content %}

Whenever I click on the submit button, I get redirected to the same form page join.html

And no data is getting saved into the db

basically submit is doing nothing

[sudden gulch]

you have to define the get method and post method

[native tide]

In my CBV you mean?

[sudden gulch]

yes

see my code

class Events_view(View):
    model = EventForm
    events = Event.objects.all().order_by('-updated_at')
    context = {
            'events':events,
            'form':EventRegistrationForm,
           }

    def get(self,request,*args,**kwargs):


        if(len(self.events)==0):
            
            messages.info(request,"no events for now.")
            return render(request,'events.html')      

        return render(request,'events.html',self.context)

    def post(self,request,*args,**kwargs):

        form = EventRegistrationForm(request.POST)

        if(form.is_valid()):
            form.set_event(request.POST['event_name'])
            form.save()
            messages.success(request,"form submitted",extra_tags="success")
            

        return render(request,'events.html',self.context)```

see ive overrided get and post and returned rendered response according to that

[native tide]

I will try to do as you told me and get back to you

bro def projects(request)

same in render(request)_

if i correctly understood your code

[fossil pond]

I get the same error

[sudden gulch]

  def projects(request):
    return render(request, "projects.html")

try this

[fossil pond]

i did

[sudden gulch]

what is the error saying

[fossil pond]

Page not found (404)
Request Method: GET
Request URL: http://127.0.0.1:8000/projects/undefined
Using the URLconf defined in .urls, Django tried these URL patterns, in this order:

admin/
debug/
[name='home']
projects/ [name='projects']
portfolio/ [name='portfolio']
The current path, projects/undefined, didn’t match any of these.

You’re seeing this error because you have DEBUG = True in your Django settings file. Change that to False, and Django will display a standard 404 page.

it's getting redirected to undefined

[sudden gulch]

strange

code is correct

[fossil pond]

stays at projects for a while

[sudden gulch]

check project urls.py

[fossil pond]

and then goes to projects/undefined

[inland oak]

https://docs.djangoproject.com/en/3.2/ref/urlresolvers/
apply reverse url, that's cooler than writing direct html

[sudden gulch]

are u using js in this html

[fossil pond]

yep

[sudden gulch]

so check if u write some redirect code there

[fossil pond]

wdym

[sudden gulch]

you can redirect using js also

so if u wrote some js code which redirect you to some value

because undefined is a js data type

[fossil pond]

ah makes sense

thanks

well if anybody knows Django

please help me in #help-chili

[supple lantern]

I want help in django please
when I open django admin dashboard then all model tables are show but add delete edit option not showing?
what should I do?

[ionic raft]

If you register a model to admin.py it will show the model. Admin only shows those models you have migrated and registered. To edit or delete a model you need to work with models.py.

[supple lantern]

I already ran command makemigrations and all tables are showing but option like add edit delete not showing?

[ionic raft]

Did run the command migrate?

[supple lantern]

no

should i run for this?

[ionic raft]

python manage.py migrate is required to make the changes to the DB. makemigrations is just prepping the files for the change

[ionic raft]

And again, admin does NOT show edit or delete commands for the DB structure, only data. You edit/delete models in models.py

[supple lantern]

okay

[ionic raft]

You use admin to edit or delete records. But the DB structure is all driven by models.py and makemigrations/migrate commands

[supple lantern]

I'm not talking about commnds
I'm talking about buttons which are appears in django admin such as add new, or delete item

[ionic raft]

Right. But you've not migrated the changes to the DB yet

[supple lantern]

yes exactly I want to edit or delete records only

[supple lantern]

yes right

[ionic raft]

And to do that, you need to run migrate to change the DB model.

[supple lantern]

will do it

[supple lantern]

thanks a lot

[ionic raft]

I would suggest watching a tutorial or reading a book on understanding how the Django ORM works.

[supple lantern]

yes I will do

[ionic raft]

You're welcome.
As a tip, I backup with version control before makemigrations and migrate. Those two commands can have interesting results if your model is not perfect.

[supple lantern]

oh okay got it

[ionic raft]

The only time I've ever needed to hard reset a git branch was on changing the model and having a field setting incorrect. In particular, default values for image fields are nasty if you get them wrong.

[grave raft]

I am using django-rest-knox everything like login and register from postman is working fine but I can not create user from admin panel as it do not show email field
Do I also have to update admin.py for django rest knox??

[ionic raft]

Django question: I have just created a new template with an image. In dev the template and image renders perfectly. In prod it will not load.
When pushing the new image to prod I can see the additional count in collectstatic. So I know the image is brought over. And bear in mind, this is an established prod deployment that has many images.
Why would an image in the same static directory successfully serving up images not load in prod when it clearly loads in dev? Using nginx.

The irony is, I'm only creating this page because I need to get a URL path to be able to render these images for articles.

[quartz yacht]

Does anyone know how to get context data within a function based view in Django?

I know how in a class based view, but that's not translating for me.

not translating in a function based view.

[nova sonnet]

you would normally make a dict containing the context then pass it through with the request

[quartz yacht]

What if the data is in the model?

[nova sonnet]

what do you mean by that

[quartz yacht]

I have a function based view to create an object, and within that object I want the end user to select a specific object from the model to attach it to. Like, Book to Author, the user can name the book and then choose from a list of authors and assign the book to the author.

The list of authors is coming from the model.

[nova sonnet]

so you want the list of authors as context?

[quartz yacht]

I think so, yes.

[nova sonnet]

all authors or specific authors?

[quartz yacht]

Specific, I want to filter based on the user to entered the authors name.

[nova sonnet]

are you going to get the authors name through a form? if so you can access the POST/GET data through request.POST or request.GET

[quartz yacht]

Yes, I have a form that they'll be filling out.

[nova sonnet]

so I'd say filter the authors using whatever author the user puts in the form and pass that in as context, are you trying to access the data the user is inputting into the form?

[quartz yacht]

I want the user to select the author from a dropdown list

like this

[nova sonnet]

So what is the issue? Is it the drop down or filtering the authors?

Once you get the list of authors you can iterate it for the drop down

[quartz yacht]

I don't know how to get the list of authors from the model within a function based view.

I know how to do it in a class based view, not a function based view.

[nova sonnet]

And you want to filter the list of authors depending on the book title?

[quartz yacht]

 def get_context_data(self, **kwargs):
        context = super().get_context_data(**kwargs)
        context['form'].fields['author'].queryset = author.bjects.filter(customer_id=self.request.user)
        return context

No I want to filter the list of authors based on the creator

That's what I use for a class based view and it works well, but I want a function based view due to some extra processing and that's what I'm more comfortable in.

[nova sonnet]

What are you specifically filtering for when it comes to the authors because im a bit confused

[quartz yacht]

I want to list all authors, and then filter for authors that were entered by the logged in user.

For example, if there are 100 authors in the model, I want to only display the authors that I've entered myself.

[nova sonnet]

So you want to list all the authors the user can pick right and which ever one they pick all books from the author will be shown right?

[quartz yacht]

basically.

[nova sonnet]

You want the user to input it though a drop down or input?

[quartz yacht]

I want the user to select the author through a dropdown.

[nova sonnet]

Will the books only show when the author is selected or will it show before and after when the author is selected?

You’d want to pass in 2 querysets, one for the authors and books

[quartz yacht]

It's not that complex, I literally have a blank form, I want the user to enter a book title and then select from a dropdown list the author.

Book Name "Harry Pawter"

Select from a dropdown list of all authors that I manually entered.

[ionic raft]

Django question: I've deployed a web site in production through Docker/Nginx. When I add static images I can go to the docker container and collectstatic. Is there a way to configure the ngnix.conf file to update static files after the build? Currently, this is not happening automatically.

[nova sonnet]

Get whatever the request.GET data is and pass that in the filter for the for the books.

[quartz yacht]

I can do a get within a post request, or would I perform it on the outside of the post request.

@ionic raft I can't answer your question specifically but Django has a 3rd party app called WhiteNoise that will allow Django to serve the static files no problem.

[ionic raft]

Thanks. I'll keep that in my back pocket. The existing deployment is working very well. I can manually collectstatic after a docker build, but I am wondering if I can enhance the existing application

[nova sonnet]

What do you mean by this?

[ionic raft]

The end result is this: https://lanesflow.io/articles/article/4/

[quartz yacht]

btw @nova sonnet I really appreciate your help on this.

[nova sonnet]

You can check if there is any GET data through an if statement in the function (such as if request.GET: <do something>)

[quartz yacht]

Ok, I'll try to figure it out then.

[ionic raft]

I did some further testing. it turns out, if you run collectstatic the docker build/nginx caches static files for future builds. I only have to run collectstatic once for new files. That's a relief 😄

[tawny pollen]

hello django newbie here I have a question

[stark tartan]

How to get the request user in .save method in django

[ionic raft]

It's best just to ask away 🙂

[ionic raft]

Can you elaborate? Are you trying to save the user triggering the request somewhere?
If so, I would look to store the user into a user field in a Model.

[tawny pollen]

path('author/int:pk/update/', AuthorUpdate.as_view(), name='author-update')

in the above path function, can i change int:pk to just pk ? like

path('author/pk/update/', AuthorUpdate.as_view(), name='author-update')

[ionic raft]

No. Because by doing that you're hard coding the letters pk into the path. The int:pk is explicitly telling Django that it's a variable. It will look for that variable from the static link in the template.

[tawny pollen]

thanks

is it better to use generic views or class/function views?

[lapis stratus]

Hello, "Unable to log in with provided credentials." I have this error but when I check the network tab and check the request payload my credential was correct.

[neon osprey]

Just searching for some more information, I'm trying to make an full stack web application with Flutter & Djanjo, but apparently if I do this, it's actully called a ' Progressive Web Applicaiton' ? Would you still call it a Full Stack Web Application?

[lapis stratus]

Hmm have you tried using lighthouse and check it if your application considered as a PWA? In the project I have right now I'm trying to make the application as a PWA.

[inland oak]

https://discord.gg/code try to go here. they have OS channels

[patent cobalt]

The other invites are also related to the question, right?

[inland oak]

yes

at least of them should be sent

they were leading to the same server

[patent cobalt]

[inland oak]

Code Monkeys discord server has OS channel too

yeah, thanks

[opaque rivet]

I've got a prod server with docker containers running. Say I wanted to push an update from dev -> prod, do I always have to git pull, then restart my containers? Or is there a better way about this?

[inland oak]

I prefer doing it with ansible
it allows me

1. relaunch the deploying script from my working PC for quick update
2. or having ability to destroy server and install to fresh one from zero with the same one command

no attachments that pollute the server beyond your code, everything is version controlled

[opaque rivet]

But in either case, the prod server will not be usable once the update occurs right? So the website will be down?

[inland oak]

ansible => connects to servers => installs docker if it is missing => copies the code and builds the image and runs

[inland oak]

yes. There is quick solution about it though

for example if you would be using Hetzner provider, they allow Floating IPs

temporally attached to any server

you could have it attached to your domain

and when you update

you... create new server

install, check that everything work

and then in one click reattach ip to new server

if everything goes ok, you destroy old server, if not, switch back

same could be done manually if you will have additional server with reverse proxy

[opaque rivet]

Cool, so essentially a second server on the old codebase while the main prod server gets updated. I think AWS has some feature like that too

[inland oak]

I think it is called Blue-Green deployment, when both environments exist at the same time

[inland oak]

essentially, old server has old code base, new server is installed with new code from zero.

switching accurately traffic from first to second one, while looking if we need to switch back in case of emergency

https://paste.gg/p/anonymous/656a1af07ef042628e7ebee644265f77
in product create page productimageform is having product field why?

[opaque rivet]

Say you had a domain and an A record that points to your prod server IP. Could you add a second A record to use if that first one can't connect?

Redirecting to a different server essentially

[inland oak]

as far as I know A records work like... primitive load balancers, users got sent randomly to one of them

you could have several servers raised with identical software

and distribute your user load between them

through DNS usage

[opaque rivet]

Hmm, this is definitely worth a read. I feel like there is definitely something out there with AWS that probably solves this. I'll have a look there later.

I appreciate the help :)

[inland oak]

you could ask, what would be issue, and why would it be primitive? Answer: there is no healthcheckers. If one of servers is down, % of users would be still sent to dead server

normal load balancers (like Haproxy) can have healthcheckers

sending only if the servers are alive

[inland oak]

u a welcome ;b

quite loving a bit of devops. it makes life easier to devs.

[opaque rivet]

I'm liking it too. All started with Docker! Lovely to have on the CV too :)

[inland oak]

me three 😉

tbh I even decided having devops as my secondary direction

I'll first finish learning essentials for high level backend though

then I will dive in a more advanced devops

[neon osprey]

Yeah I've seen that, although I thought Full Stacks, didn't do PWA to be honest, I'm not sure if this is frounded upon rather doing full applications

Is there anyone with experience architecting django?
I stand before the decision on splitting an app into small apps or modules but I do not have enough experience architecting django and some consultation would be very useful.
It's difficult to ask a more specific question on this topic.

[inland oak]

django apps represent basically modules

each django app has separate set of tests / views / model

best recomendation is usually separating into django apps, if you feel that those are two different entities and logically they should be tested separately

usually separating into another django app... comes from the size of the thing

if you know that it will eventually be big one, feel free to separate, in order to not overbloat the current app

[gusty wagon]

Does anyone know if its possible to manage the search results of google by geo location? For example, when having a real estate listings website, and you are in New York... when googling for offices. You will get Offices in new york... But for real estate listing websites this is crucial. I want to show my top visited pages or most important ones, and not the one where the user is located at. Anyone have an idea how to tackle this? Please tag me.

[opaque rivet]

@gusty wagon could use the IP of the user to determine their location. Then show listings based off that.

[opaque rivet]

first thing that comes to mind:

clique = serializers.StringRelatedField(many=True)

The Clique model has a one-to-many relationship to Post (with Clique being on the one side, and Post being on the many side), so many should be False.

clique will always be a singular object, which is not iterable, hence the 'Clique' object is not iterable error

[manic crane]

ohhhh hmmmmm

time to problem solve & thanks very much

[manic crane]

but der can be many cliques ?

[opaque rivet]

one Clique object to many Post objects unless I've missed something.

[manic crane]

oh no i can make more than one clique

[opaque rivet]

can you elaborate?

[manic crane]

like i the drf request page it lets me make more than one clique

more than one post

wait actually just revised on one to many relationships

[cerulean badge]

i am getting this error
An invalid form control with name='description' is not focusable.
i rendered the form with crispyforms
and have this

<script src="https://cdn.ckeditor.com/ckeditor5/29.2.0/classic/ckeditor.js"></script>
  <script>
    ClassicEditor
        .create( document.querySelector( '#id_description' ) )
        .catch( error => {
            console.error( error );
        } );
  </script>```
what i got to know is that ckeditor makes the input hidden and it is required.
this error is raised when you submit the form because the input remains empty when validating
i added `blank=True` to description field but i want it to be required you know of a better solution?

[manic crane]

ohhh i get the many to many relationship one clique but many posts !

[opaque rivet]

one-to-many, yep

[opaque rivet]

what if you attach that function to the onSubmit attribute of the form?

[manic crane]

ok so to fix is to set many false ?

[opaque rivet]

it would be a step in the right direction

[manic crane]

thanks dude

[cerulean badge]

which function?

[opaque rivet]

Possibly you could make this into a function?

<script>
    ClassicEditor
        .create( document.querySelector( '#id_description' ) )
        .catch( error => {
            console.error( error );
        } );
  </script>

[cerulean badge]

its ckeditor script, you need it for wysiwyg editor

[opaque rivet]

ah okay. wasn't sure what that does. i'm not sure then!

[tawny pollen]

i have a django question. can someone help me ?

[opaque rivet]

go ahead

[tawny pollen]

the date doesn't show on the template. I am using generic views

[opaque rivet]

show the view? is the date a datetime object?

[tawny pollen]

class AuthorDetailView(generic.DetailView):
    model = Author
    context_object_name = 'author_detail'
    template_name = 'catalog/author-detail.html'

    def get_context_data(self, **kwargs):
        context = super().get_context_data(**kwargs)
        context['author_list'] = timezone.now()
        return context

yes date time object

[opaque rivet]

that I know of, objects can't be represented in templates. So you can convert it to a string:
https://www.programiz.com/python-programming/datetime/strftime

[tawny pollen]

i heard you can do something like this : {{ book_detail.date_of_birth|date }}

or like {{ book_detail.date_of_birth|date:'Y-m-d' }}. but it didn't work for me

[opaque rivet]

I'm not sure as I don't work with templates, but you could .strftime() in the get_context_data() method

[tawny pollen]

ok thanks. i'll try

[light cloak]

Does anyone know if it's possible in Django to access management form attributes inside a template? I'm trying to dynamically add new form fields but I think the management form TOTAL_FORMS field needs to be updated for extra forms to be submitted. Any ideas?

[opaque rivet]

what looks better?
1.

I prefer 1. because it fills more horizontal whitespace

[light cloak]

Yeah, 1

[fossil pond]

1 for sure

[opaque rivet]

thanks 👍

[ionic raft]

A LOT. Django/Flask are web development frameworks. Google sites built with Python and you'll see some big players come up.
Flask is great for getting going. Django is amazing for more complex sites (there's a link on my profile to a site I built with Django/Python. Didn't know any Python before April 16, 2021.

[ashen parrot]

oh

[ionic raft]

Side by side for sure. More obvious that it's a choice

[ionic raft]

If you want a fancy front end you can add a JS Framework like React of Next.js to the mix. However Django/Flask are very powerful application layers. When you pair Django with a Postgres DB you have a stack that is truly enterprise ready.

[ionic raft]

You need to combine both. For example, {{ article.date_written|date:'F j, Y' }}

[ionic raft]

You can use strftime in the view, but I typically go with a consistent format in the DB and use the |date:'F j, Y' formater in the template.

[opaque rivet]

which color of button is better?

[ionic raft]

Interesting question. The bottom button has greater separation, and feels more suited as a CTA. However, if the text 'Let's dive in' is not clickable I wondering if it might distract...

[ionic raft]

That said, once you pick your CTA colour and consistently apply, I say that lighter blue is better. It flows with the darker blue above and yet stands out.

[opaque rivet]

Ok, I'll remove the "Let's Dive in" and have them the blue color

[ionic raft]

What is more important...that the user finds or reviews?

[opaque rivet]

this is for the mobile view which is a bit different

[opaque rivet]

I'd say they're the same

[ionic raft]

What about both buttons the same lighter blue? Maybe see that with a screenshot of the entire view?

[ionic raft]

Oooo...
Is UniHalls a hyperlink?

[opaque rivet]

Footer, redirects to main page

[ionic raft]

I have to say (and this is but one opinion) I definitely prefer the lighter blue, and a consistent CTA. But then that's a preference. I want to train the user to know what to click and they don't have to think about it.
With the clickable logo being the same colour that fits

What about 'Contact us' text also being the same CTA blue?

[opaque rivet]

Nice, I agree

[opaque rivet]

Will do. Gonna go for a run now though ;P

this is the view on a computer

and this for the mobile. added some shadows and I think it looks nice

[ionic raft]

In short, everything that is a CTA is that blue. And seeing the lighter blue on the darker blue...yes. I like.
I'd change the two buttons on the computer view to the lighter blue too

I'm a HUGE fan of button shadows...
Interestingly, I break my own rule with the Support and Signout buttons.
All text links are the light blue. But the signout I make white so that it stands as a secondary click.
Support is dark blue because I'm not looking to drive them to create support work for us 😄

[opaque rivet]

I think it looks worse. Maybe because of the "lets dive in"

Actually it looks alright... hmmm

[ionic raft]

Agreed. Either remove the Let's dive in, or change to dark blue.
But I think it's a redundant invitation.
Also, change 'contact us' to same lighter blue perhaps?

But then, you've posed the question...Ready to get started? This is the invitation. Let's dive in doesn't add anything. The buttons are clear implication for behaviour

[fossil pond]

Hello guys! I want to send {{projects.thumbnail}} object in Django (which contains an image) to onmouseover="DisplayThumbnail()" as a parameter inside DisplayThumbnail so that it can be processed by JS. Is it possible?

[ionic raft]

I would keep the space between the words and the buttons equidistant above and below. If you remove the dive in, keep the white space...And now that I think about it, keeping contact us as dark is solid option too. Contacting is not really a CTA

[fossil pond]

i love it dude

[opaque rivet]

@ionic raft I'll test out colors later, heading on a run.

@fossil pond you think light blue > black?

[ionic raft]

Enjoy. 😄

[opaque rivet]

Thanks! 👍

[fossil pond]

The light blue and black combo looks sick yeah.

[ionic raft]

I think that the lighter clue as the CTA is a very nice combo with the darker blue...

[opaque rivet]

I mean, for the color of the two buttons, on the light gray background

Aah, design is my downfall 😁😁

At least I can change things quick with tailwindcss

[fossil pond]

Yeah I can relate. Having a designer as a partner would be pretty amazing ngl.

[ionic raft]

The lighter blue is definitely preference for me on the light grey background...
Here's my latest UI...very close colours to what I've gone with...
My big challenge was picking a CTA colour for a data rich experience. This is a portal for project management after all. In the end, making all text links that light blue really pulled them forward. I'll be curious what alpha testing reveals

[ionic raft]

Your focus on the smartphone app form factor is ideal. Your target market will mostly be using this on their phones.

Thank you bro for helping Thank you so much

I was looking for this for hours

[glacial yoke]

My project is giving me the error with status code 500, which means that I haven't got the same methods used in my http requests/api calls. Even though the methods are the same in both my django views.py, and my react frontend axios get function:

class UserView(APIView):

    def get(self, request):

function isAuth(){
    const response = axios.get("/user")
    console.log(response.data)
  }

this is the error:

createError.js:16 Uncaught (in promise) Error: Request failed with status code 500

[inland oak]

u a using promise based js library
https://github.com/axios/axios

correct get requests with it:

const axios = require('axios');

// Make a request for a user with a given ID
axios.get('/user?ID=12345')
  .then(function (response) {
    // handle success
    console.log(response);
  })
  .catch(function (error) {
    // handle error
    console.log(error);
  })
  .then(function () {
    // always executed
  });

// Optionally the request above could also be done as
axios.get('/user', {
    params: {
      ID: 12345
    }
  })
  .then(function (response) {
    console.log(response);
  })
  .catch(function (error) {
    console.log(error);
  })
  .then(function () {
    // always executed
  });  

// Want to use async/await? Add the `async` keyword to your outer function/method.
async function getUser() {
  try {
    const response = await axios.get('/user?ID=12345');
    console.log(response);
  } catch (error) {
    console.error(error);
  }
}

speaking in python terms, you used coroutine function, which you did not await ;b

[glacial yoke]

So if I await it, it should work?

[inland oak]

nah, better use then instruction

[glacial yoke]

Does it make much difference tho?

[inland oak]

const response = axios.get("/user")
console.log(response.data)

replace to

axios.get('/user')
  .then(function (response) {
    // handle success
    console.log(response.data);
  })

[inland oak]

my javascript knowledge is enough to know that this version will work

[glacial yoke]

Ok, thanks, will try it out

[inland oak]

while await I am not sure if will work, because it could be requiring additional requirements... like async env, what needs for that in js I have no idea.

[glacial yoke]

Ok

nope, it still gives the same mistake @inland oak

I've tried to add async and await to it

and it gave me this error:

Uncaught ReferenceError: regeneratorRuntime is not defined

oh right, that's probably because my babel config can't transpile it

give me a sec

ok, I fixed the babel part, but I still get the error 500

How else can I try to fix this? @inland oak

[opaque rivet]

@inland oak .then() is just syntactic sugar for await. However, I don't know how you'd handle errors (non 2xx) with await.

[inland oak]

Oh right, it is not js part

You have django crashing with 500

[glacial yoke]

Yeah, the error is definitely happening on the backend

but idk how to fix it

[inland oak]

Enable debug true

[glacial yoke]

it is

[inland oak]

And read

Resp o nse body

[glacial yoke]

from the console?

[inland oak]

Use .then, with error catching

.catch

And just read the error from response

[glacial yoke]

assert isinstance(response, HttpResponseBase), (
AssertionError: Expected a `Response`, `HttpResponse` or `HttpStreamingResponse` to be returned from the view, but received a `<class 'NoneType'>`  
[03/Sep/2021 22:24:49] "GET /user/ HTTP/1.1" 500 80418

this is what it gives in console

[inland oak]

Or see django error log

[glacial yoke]

if it says anything to you

[inland oak]

You return something wrong in /users view

In python

I am facing a certain issue with Django. When I upload picture to my model it gets saved on static/images but when I run the code it looks for the image in the folder static/images/projects (projects is the name of the html file

[glacial yoke]

It's returning json

[inland oak]

How it returns Json

[glacial yoke]

as a serializer

user = SteamUser.objects.filter(steamid=payload['steamid']).first()
        serializer = SteamUserSerializer(user)
        return Response(serializer.data)

Response() is a rest_framework function

[inland oak]

Looks legit

Hello can someone help me , when i type py manage.py collectstatic there's no css for the admin page while my static settings is

STATIC_URL = '/static/'

STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles')

STATICFILES_DIRS = [
    os.path.join(BASE_DIR, "static"),
        ]

STATICFILES_STORAGE = 'whitenoise.storage.CompressedManifestStaticFilesStorage'

[late gale]

Oh you still here , long time

hehe

[inland oak]

Let's start with saying, that whitenoise is bad

Really bad

[opaque rivet]

@fossil pond what's the code?

[late gale]

ok gonna remove it but i believe that wont create css admin

[inland oak]

No idea how u run the server

[late gale]

py manage.py runserver

normal way

[fossil pond]

urls.py:

urlpatterns = [
    path('admin/', admin.site.urls),
    path('__debug__/', include(debug_toolbar.urls)),
    path('', include('main.urls')),
]


urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
urlpatterns += static(settings.STATIC_URL, document_root=settings.STATIC_ROOT)```

settings.py:

```STATIC_URL = '/static/'
STATIC_ROOT = 'staticfiles'

STATICFILES_DIRS = [
    os.path.join(BASE_DIR, 'static')
]

MEDIA_ROOT = os.path.join(BASE_DIR, 'main/static/images')

[late gale]

i have css for my admin on other site while they have the same static settings

[glacial yoke]

check your templates code in settings.py

[inland oak]

Enable debug then.
Runserver is for dev anyway

[late gale]

it's enabled

[fossil pond]

projects.html:

                        
                        <ul class="list-group mx-auto justify-content-center list-group-flush">
                            {% for project in projects %}
                                <li class="list-group-item"><a href="#" class= "project-link" style="text-decoration: none;" onmouseover="DisplayThumbnail('{{project.thumbnail}}')"><span class="projects-title">{{project.title}}</span>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<span class="projects-summary">{{project.summary}}</span></a></li>
                            {% empty %}
                            <h4 class="display-4">There are no available projects as of now :(</h1>
                            {% endfor %}
                        </ul>
                          
                    </div>
                    <div class="col-6" id="ImageContainer"> 
                        <img style='height: 100%; width: 100%; object-fit: contain' id= "thumbnail" src="{% static 'images/rdr2.jpg'%}">
                    </div>```

project.thumbnail is the image basically

[inland oak]

Shrugs then.
Fell asleep

[fossil pond]

Didn't change anything its basically this:

    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [],
        'APP_DIRS': True,
        'OPTIONS': {
            'context_processors': [
                'django.template.context_processors.debug',
                'django.template.context_processors.request',
                'django.contrib.auth.context_processors.auth',
                'django.contrib.messages.context_processors.messages',
            ],
        },
    },
]```

[glacial yoke]

hmmm, seems strange

how is it imported into your html/css?

[fossil pond]

yea have to manually place images on that folder quite cumbersome

[late gale]

what shall i do then , nuke my project ?

hahaha

i have css admin in staticfiles folder

but not in static folder

gonna copy it and add it in static folder

they are the same so

[fossil pond]

views.py for the main app:

def projects(response):
    projects = Project.objects.all()
    return render(response, "projects.html", {'projects': projects})

Other than that it's all basic stuff

[glacial yoke]

can you send the error traceback

[fossil pond]

No error traceback. When I make the folder and put the images they get displayed. When the folder isn't there i get a 404 saying image not found

Not Found: /projects/coolman.jpg
[04/Sep/2021 01:12:52] ←[33m"GET /projects/coolman.jpg HTTP/1.1" 404 3102←[0m (when I don't manually place the image inside the projects folder)

[glacial yoke]

wait, so if you are uploading the image to your model, then it should save in db, right?

[fossil pond]

Uploading it from the admin panel. It's a model class attribute.

    title = models.CharField(max_length=200)
    thumbnail = models.ImageField(null=True)
    body = models.TextField()
    slug = models.SlugField(null=True, blank=True)
    summary = models.CharField(max_length=200)
    created = models.DateTimeField(auto_now_add=True)
    id = models.UUIDField(default=uuid.uuid4, unique=True, primary_key=True, editable=False)

    def __str__(self):
        return self.title   ```

Basically the thumbnail

[glacial yoke]

Yeah, I'm not sure if there is a way to fix this

only if you can somehow change the directory of where your images are saved if you upload it from local storage, because usually it is just saved as a link, and it can easily refer to it from anywhere

[fossil pond]

omg i fixed it!!

replaced project.thumbnail with project.thumbnail.url in the html

worked

[glacial yoke]

yeah, i was thinking that it had something to do with project.thumbnail, but wasn't too sure

well done

[late gale]

any image should has .url

since it directs to the url of the image from static folder

but nice

[opaque rivet]

Think I'm burnt out, think I just spent 2 hrs for a simple react animation

[solar lodge]

Anyone one the best way to make a select menu like this?

[wide canyon]

I want to start reading a few technical books. I'm starting from obey the testing Goat. Dies anybody want to join me? We'd act as accountability partners and discuss what we read at intervals

[ionic raft]

Oh that doesn't sound so good. I'm holding off on starting learning React. Building a billable hours app for consultant subscribers in my web app.
I do need to get to the Map App next though...and that means React!

[ionic raft]

That's a question that when I started to get answers became a rabbit-hole...uploading media....
In the end, I dropped profile pics and logos entirely. I opted to not use media entirely. If you upload images to the app server (/media/) then you lose statelessness and potential for load balancing. If you upload images to the DB other risks surface. I kicked that can down the road.

It's one thing to have media in development. But in production, it's another matter entirely.

Guys i need help in django, i have two views, one is to delete something and another one get it. However, when i call the view to delete and view to get it at the same time, it actually gets the result before it is even deleted

How can i fix this... i know this is about smtgh like async but i'm pretty weak in this

[fast lava]

can anyone help me

in

#help-rice

If somebody knows Django

[worthy lake]

# profile/<str:pk>/edit/
class UserProfileUpdateView(LoginRequiredMixin, UpdateView):
  ...

this is not sufficient for this view. Not only should the user be logged in, but they should have to be the exact user specified in the url. in a class based view (same as always) I dont know where to put this logic.

[inland oak]

Some form of locks is necessary to deal with it. Which lock implementation to use depends on... what u a building, student/work and etc

If to say simplest choice use redis-locks to block access to object during operation. Redis locks are universal and fast. They use key-value in RAM memory.

If u a dealing with sql database, they have their own database level locks

The most simplest and primitive, would be just blocking by creating file and checking its existence

[inland oak]

It will make sure to deal with one object in.. sequence. Depending on which operation will reach django first.

If it is not sufficient for you, you could lock object in advance. Not knowing your case enough to suggest more precise answer

Unless u know for sure, I would recommend redis locks. They are meant for this, fast, comfortable code interface

The most precise locks would be probably database level locks, but I am not sure if there are good libraries to deal with it. Django ORM supports them or not

        return Response({'message','You have left the room'},status=status.HTTP_200_OK)

Here's part of it, but i couldn't understand what ur saying hehe

The solution i have atm is

To use setTimeout

But i'm not sure if it's the best solution

In the original case, room is get before it is done deleting

        return Response(
            {"message", "You have left the room"}, status=status.HTTP_200_OK
        )

a bit of formatting before doing anything

you know.. the simpliest solution would be just

returning proper error that room got dissapeared

where you request the room

return something like

return Response(
            {"message", "The room was deleted"}, status=status.status.HTTP_410_GONE
        )

pooof. no problem. ;b

hmm.

oh wait

that can be done simplier ;b

see... the problem we have

that you keep in which user room in session

[lime frigate]

What if userin room is ran before the Response is called

[inland oak]

so... if we have always delay between operations

while requests reach the server

think about using cookies 😉

cookies store user info client side

[lime frigate]

Hmmm

[inland oak]

so you can be fast enough to delete information about him leaving the room

or client side local storage, whatever

[lime frigate]

Are the syntax almost the same

[inland oak]

not really

client side operations are made in javascript mostly

cookies can be accessed/created server side at the same time in python

so... it is like a mix of two languages here, and mix of frontend and backend

====================================

essentially you would have something like this....

User creates Room, he gets cookie, preferably JWT Token, that he is in this room, and that he is the host (you have logic like this, right?)

User leaves the room... Request is sent to server to delete the room in case he is host, and his cookie is deleted

[lime frigate]

Yes....

[inland oak]

a bit unsafe, since in order to delete the cookie we will need it being visible to javascript, but it should work

[lime frigate]

Hmm great idea

But which one is usualy used

[inland oak]

Cookies in the form of JWT Tokens have verifications that they were produced by your server
