[hushed barn]

@toxic flame So should i just start a new project and quit this 1 because no 1 can figure it out

[native tide]

only 10... wow

@hushed barn maybe change what your view returns

and does your console say anything?

[hushed barn]

but if i cant even open an empty page

console says nuthing

it worked yesterday but doesnt work anymore i didnt do anything

[steady maple]

if ur 10 u cant be on discord

[native tide]

this ain't the place...

[hushed barn]

yes well i can be with a guardians permission and if i am mature enough

[steady maple]

oh ok

[native tide]

@hushed barn and the other routes work fine?

[hushed barn]

Yea but the from products.views import* does nothing to my code

unused imposrt statement

[native tide]

you don't need that.

from products.views import * imports everything form products.views, but in your products app you import them anyway

[hushed barn]

done

But could it be something to do with my firewall?

maybe a runserver command

[slim beacon]

firewall wouldnt stop you from connecting locally i think

[hushed barn]

yea true but maybeee ya know

[native tide]

well, I think it points to something external blocking it. Nothing shows in the console, and the routes look right

@hushed barn Can you send us a picture of your console

The "run" tab in pycharm

[hushed barn]

hey can you join a channel ill scweenshawe

oh it dont work

[native tide]

simpler to just send a screenshot of the run tab

[hushed barn]

oh what the fuck

[native tide]

well... there's your answer... since you ran into an error the server stops and when you retry the connection the server isn't running so it refuses to connect

[hushed barn]

so how do i fix that

i need to define enviroment?

[native tide]

I've never ran into that problem so idk

give it a search

[hushed barn]

yea well thanks a lot tryna fix this up

[blazing sapphire]

am i doing something wrong here. it just doesnt get redirected to the home route

  res.sendFile(__dirname + '/client/test.html');
});

app.post('/test', function (req, res) {
  setTimeout(function () {
    res.redirect('/')
  }, 5000)
})```

[native tide]

@blazing sapphire what if you specify the function in setTimeout outside of that block, then reference it inside setTimeout? I don't know whether that's the right usage of it.

[blazing sapphire]

even if i remove setTimeout, it still doesnt work

[native tide]

@blazing sapphire are you using react?

[blazing sapphire]

no

[hushed barn]

@native tide im dying here why does this show errors im doing it exactly like i read the page

[native tide]

read the error on the side, hover over the red for the error

you need a comma on the products path

because its a list

[hushed barn]

ok thanks

[native tide]

hey guys I just learned the basics of flask by watching a 1hr video by FreeCodeCamp
i'm confused what should I do now?

what projects should I make?

I tried googling but still confused lol

help

[rustic pebble]

make a covid cases tracker

@native tide

[native tide]

🤔

how?

@rustic pebble

[rustic pebble]

Figure it out

Lol

Its a project

[native tide]

ok

so I can a covid tracker with python like this (or some other way) and deploy it using flask and heroku? @rustic pebble

https://www.codesnail.com/coronavirus-tracker-in-python/

[rustic pebble]

Yes

[native tide]

thanks for the help

I will try to figure out th rest on my own

[rustic pebble]

alright

good luck

[native tide]

and is that code the only way to make a covid tracker?

[rustic pebble]

No

[native tide]

I want to do something by myself and not copy the code

[rustic pebble]

You can create your own wrapper

[native tide]

wrappers = decorators?

[rustic pebble]

No

You can make a background job that checks this folder:

https://github.com/CSSEGISandData/COVID-19/tree/master/csse_covid_19_data/csse_covid_19_daily_reports

Every day

And updates a database with all countries

[native tide]

🤔

ok

[rustic pebble]

Or you can just increment the day by 1 in this url

https://github.com/CSSEGISandData/COVID-19/blob/master/csse_covid_19_data/csse_covid_19_daily_reports/11-24-2020.csv

It is CSV so parsing it is easy

[native tide]

oh

it is called web scraping?

with bs4 and other libraries

[rustic pebble]

Its not rly scraping since you have direct access to the file

[native tide]

oh

[rustic pebble]

All you need is the raw

So basically this link

https://raw.githubusercontent.com/CSSEGISandData/COVID-19/master/csse_covid_19_data/csse_covid_19_daily_reports/11-24-2020.csv

A simple request would do it

data = requests.get(f'https://raw.githubusercontent.com/CSSEGISandData/COVID-19/master/csse_covid_19_data/csse_covid_19_daily_reports/{current_month}-{current_day}-{current_year}.csv').text

As simple as that

[native tide]

oh

I get it

so I have to parse the repo and check for new files daily (for which I can write an automated script? or smth? idk)
then I can make a flask application that displays it on webpage

?

[rustic pebble]

You can get current date with the following

from datetime import datetime
current_month = datetime.now().strftime("%m")
current_day = datetime.now().strftime("%d")
current_year = datetime.now().strftime("%Y")

[rustic pebble]

The best would be to use a database

[native tide]

ok

I have postgrs and mysql installed on my laptop but I never used them

let me search on my own

gtg to eat

[rustic pebble]

You will need to use an sql module for flask

the one I use is Flask-SQLAlchemy

[native tide]

SQLALCHEymy

yes

[rustic pebble]

Which provides on ORM

[native tide]

ik that

[rustic pebble]

Object Relation Map

[native tide]

ok

can I ping you when i'm back?

[rustic pebble]

sure

[native tide]

thanks

cya

[native tide]

Will script(js) file be running on browser when rendering html using flask?

[native tide]

@rustic pebble what is that raw github link ? and from where you got that ?

I decide to first write a python code and then try to make a flask page on it

[bright trench]

o

[past cipher]

how to read a config key in my main route files? I thought it was something like app.config['secret_key']

secret key is set inside init

I want to read the value inside one of my routes

nvm done it, I imported app instead of doing from app import app

[native tide]

how does web development works with python?

[pine yew]

@past cipher you'll also need current_app inside of a view

@native tide the same way as other languages, through a web framework. In Python, you have quite a selection but the most stable choices are Django and Flask

Django gives you more tools out of the box, Flask is extensible and relies on plugins

[native tide]

why would you make a web with python instead of using basic html?

[past cipher]

thanks @pine yew I already got it sorted

@native tide you use Python for the back-end

you still need to use html

for front-end

[pine yew]

There are two parts to a website, the backend and frontend. Your backend is usually written in pretty much any language, such as Python. Your frontend will always be a collection of html, css, and javascript.

[native tide]

ohh

is it matter the language?

[pine yew]

no, not really

[native tide]

oh ok thanks

which your prefer? flask or django?

[pine yew]

I use something called FastAPI because I mostly make REST APIs at work

and it has a lot of great features

[snow sierra]

but, how can you explain member everything about Django to HTML ?? sometimes Youtube or other sources are better and the best than chatting here :x it is not Negative Feedback. it is reality.. as i started python, django, html, js, css and other more... i am not pro.

[haughty turtle]

when I call create_user() on a User model does this check first if the user exits?

[native tide]

@haughty turtle afaik the username has the unique constraint so if a user already exists with such a username you'll run into that error.

So, by that metric, yes

[haughty turtle]

Cool, thanks

this is correct also for email? I mean as I am not using usernames just first and last name, email, pass

[native tide]

I don't think the email has the unique constraint

@haughty turtle you can expand on Django's user model with your own field constraints with AbstractUser. You'll still have the User methods such as .is_authenticated etc. maybe that's what you're looking for

[haughty turtle]

def register_user(request):
    if request.method =="POST":
        request = json.loads(request.body.decode('utf-8'))
        first_name = request['fname']
        last_name = request['lname']
        email = request['email']
        password = request['password']
        re_password = request['re_password']
        if password == re_password:
            u = User.objects.get(email=email)
            if u:
                User.objects.create_user(first_name=first_name, last_name=last_name, email=email, password=password)
            else:
                pass
        else:
            pass``` @native tide Should that be good for now in checking wether email exist

[native tide]

Looks fine, but in this scenario if the email already exists, the user won't know. (User will just return an error server-side if the unique constraint isn't fulfilled). So, I would manually check whether the email is available before saving the object.

Oh, and that being said, you'll have to add your own constraint for email if you want it to be unique

[haughty turtle]

yeah I am going to add that in that if a email exist it will throw a setCustomValidity('Email is Already Registered.'); on the email input in my JS

[native tide]

Oh, cool. Are you using React? @haughty turtle

[haughty turtle]

Vanilla

[native tide]

Ah, ouch.

[haughty turtle]

Should I really look into using a framework?

I like Vanilla JS

[native tide]

Depends on your use case. If it's something simple, no bother.

But using a framework something like React is great, and the libraries available speeds up really tedious tasks such as forms, etc

[haughty turtle]

I will look into it after I finish the page and rewrite from Vanilla JS into a framework, my last project had 500 lines in Vanilla JS , this one probably more

[native tide]

But if you can write it in vanilla JS I think that's already gave you a boost in understanding the frameworks.

I went straight into React without JS knowledge and didn't know any of the terminology (I still don't understand the DOM lol) so you'll do fine

[haughty turtle]

Cool, nice to know, haha dove straight into the DOM in day 1, I mean I got the hang of JS in just one day, it was pretty straightforward.

Frameworks just offer a benefit in dev speed or more? guess I will have to look into it.

[native tide]

Yea, dev speed, page speed (React can manipulate the virtual DOM instead of the whole DOM, so no refreshing of the page) and makes everything AJAX and smooth.

I wouldn't have anything to compare it too as the only JS I use is within the framework

But it will differ slightly, if you use React the main language is JSX which varies but only slightly

[frank wedge]

Hello,
I need help with two question, if someone could help me.

1. What is the proper way to chain methods based on conditions?
   If I have a class with multiple methods and on my object I would like to chain some of those methods only if certain conditions are met. How would I do that?

2. What is the proper encoding method for transfering data to another webservice? API service.
   I'm trying to send a JSON text to another service and it seems to return an error for some characters like +, <, >... etc.
   Thank you.

[native tide]

hello everyone

[devout coral]

Hello

Anyone here have some experience with Boto3 and S3. I have a Django application and am wanting to migrate to using S3 for media files and maybe static as well. Would this be a simple transition assuming the application is already running and I have files locally of course? If so how would I go about doing it? Setting ip boto3 normally and it will upload everything automatically?

This is probably the 100000th time someone asked this but... Vue or React (or something else) and why - for Django or just in general?

[pine yew]

I like vue v3's more FP approach, just personal style

I also like their use of single-file components (SFC)

[native tide]

class NoteSerializer(ModelSerializer):
    class Meta:
        model = Note
        fields = ["name", "content", "notebook", "slug"]

        notebook = CharField(required=False)
        content = CharField(required=False, allow_null=True, allow_blank=True)

Does anyone know why even though I've specified my content field to not be required, it's still being required?

I guess the same guess for notebook

[haughty turtle]

@native tide Grow your email list through Viral Giveaways Not allowed and its not a open-source project, you require a email for it. It does not belong here and you might as well remove it.

@dense slate If you are looking for a job then React as its more popular, Vue is Opened Source, I will main it for personal projects, but employers mostly look for React based on what is being shown.

[dense slate]

Is allow_null a more recent Django change? I thought it was just null=True.

@haughty turtle Future employability aside, from ease of use and just pleasure of working with it, sounds like Vue?

[haughty turtle]

VueJS I have heard alot of good things about they say its the best of both worlds between React and Angular

Its a highly active project, and making sure to stay ahead of Google and Facebook, I will make sure to learn it as my main framework when not in relation to employment

[hollow scaffold]

Django: real quick question, is there a way to automatically create x instance of a model if x instance doesn't exist?

I.E. (delete all model instances,) or (new django db is created): if no instances exist, a default instance automatically gets generated

[native tide]

@hollow scaffold maybe this will help?

https://docs.djangoproject.com/en/3.1/howto/initial-data/

[hollow scaffold]

Thanks, I'll take a look

for reference this is my current fix lol, but have to pass exceptions for initial migration to not throw an error

def getMainMenu(): # TODO FIX THIS SHIT
    try:
        # Check if menu is empty
        if not MainMenuLink.objects.all():
            link1 = MainMenuLink.objects.create(title='Home', url='/')
            link1.save()

...
            logging.error(f"No MainMenuLink objects exist, creating defaults")
    except:
        pass
        # Return menu
        return MainMenuLink.objects.all()
    finally: 
        pass

lol

[native tide]

This is so strange

I'm making a new note, it's appended to my client-side "list of notes", but if I am hovering over a note when I "submit", it does not show until my mouse leaves that div (that note). I have been pondering over my code for about an hour now and im so lost...

[hollow scaffold]

@kindred whale thanks btw, works great

[haughty turtle]

@native tide Can you show a snippet of the code

Have you include any code that would stop the function that refreshes your items on screen from running, I have accidently done this before, where inside my function I would call an if statement to check if the item hovered is not the same to the refresh my items

[native tide]

Dude, I actually just fixed it randomly. Holy fucking shit

It came to the point where I'm just changing stuff randomly without thinking

and it worked...

And that "snippet" would be 500+ lines 😳

So thank god for that 👍

[haughty turtle]

yeah would of loved to help back, but would of needed to review code. Glad you got it fixed though

you should go back step by step and undo changes until you find that ramdom piece that fixed it so you can understand the problem better for future references

@native tide

[native tide]

Yeah

It was totally unexpected because the functionality of my component essentially mirrors the functionality of ones I already wrote (successfully).

And going line by line, everything seemed to work fine.

[haughty turtle]

Boom created a Custom User and just registered and logged in

[native tide]

I think it's something with the inner workings of React. I have a parent component with a child component, and when I press "submit" to make that note, that child component is updating the state of the parent component.

I realized a lot of the state changes of the child component were reverting the state of the parent component to its DEFAULT. So, I just removed the state-changes from the child component, and placed it all in the useEffect hook of the parent component. And that worked.

So I think what was happening was that there was some async stuff going on not as expected, still not sure lol, don't really want to know

@haughty turtle Nice!

[haughty turtle]

You have any resources that would give me a depper understanding on how sessions work

I know there is the db, cookies, or file storage sessions

but I want to understand how this would be able to authenticate a user with user info being stored server side

Only finding detailed information on cookie based sessions

[native tide]

I'm pretty sure that Django gives every user a session token which is then stored client-side as a cookie, and on every request that token is included in the request header...

Actually I think I'm wrong on that one

Pretty sure that's token authentication which is different

https://medium.com/@sherryhsu/session-vs-token-based-authentication-11a6c5ac45e4#:~:text=Session based authentication%3A Because the,stored on the client side.

[haughty turtle]

Django uses database based sessions which are stored on the database as default

while Flask uses cookie bases sessions as default

[native tide]

This is giving some good info so far

https://developer.mozilla.org/en-US/docs/Learn/Server-side/Django/Sessions

"Django uses a cookie containing a special session id to identify each browser and its associated session with the site. The actual session data is stored in the site database by default (this is more secure than storing the data in a cookie, where they are more vulnerable to malicious users). You can configure Django to store the session data in other places (cache, files, "secure" cookies), but the default location is a good and relatively secure option."

That's pretty confusing to me.

So, Django stores each user's session ID in a database, and stores it as a cookie. Then on every request compares the cookie ID to the session ID...

How is that different to token authentication?

[haughty turtle]

You can read it and write to request.session at any point in your view. You can edit it multiple times```

it seems to grab it from request.session but yeah have to dig into it

[native tide]

# Get a session value by its key (e.g. 'my_car'), raising a KeyError if the key is not present
my_car = request.session['my_car']

Yeah

The mozilla docs explain it well

I might need to use the session auth to track stuff like website visits

But I still don't get how it's different to token auth

[haughty turtle]

    if request.method =="POST":
        new_request = json.loads(request.body.decode('utf-8'))
        first_name = new_request['fname']

        email = new_request['email']
        password = new_request['password']
        re_password = new_request['re_password']
        if password == re_password:
            try:
                u = User.objects.get(email=email)
                print('Email already in use.')
            except:
                User.objects.create_user(first_name=first_name, last_name=last_name, email=email, password=password)
                print('User Created.')

                    return redirect('http://127.0.0.1:8000/portal/')```

I am trying to redirect but it does nothing

[late gale]

hey can someone help me here

def delete(request, pk):
    order = OrderItem.objects.get(id=pk)
    if request.method == 'POST' :        
        order.delete
    elif order.DoesNotExist:
        order_name = order.name
        order_name.delete()

    return redirect('Cart')

    context = {'order': order}

    return render(request, 'products/delete.html', context)

i am trying to make the user delete the an order added to the cart by the id and it removed but if i came and add it again it says it does not exist because it has new id now so i am trying to delete it using order name or idk

[verbal snow]

Im trying to raise Django's Http404 to use their 404 page, however, it 500's
https://docs.djangoproject.com/en/3.1/ref/views/#the-404-page-not-found-view

[haughty turtle]

@late gale You should not be removing items from cart server side

That is something you take care of in the frontend, with JS

[native tide]

https://gist.github.com/joepie91/cf5fd6481a31477b12dc33af453f9a1d

[haughty turtle]

what you are doing is deleting the item from the database so this is the reason why you are getting such error, as users should not be allowed to delete global items that other users would need, that is an admin function.

Will save that to read later @native tide

Thanks

[late gale]

@haughty turtle oh so you mean i have to use javascript to delete i will try then

thank you

[native tide]

@late gale you can delete by order_number and every time something is put into the cart (or bought) assign it a new unique order number

Just a thought.

[haughty turtle]

Could do that also, but then doing this in Django would it not be more complicated and offer worse UX, as for changes to take effect on the browser would cause for a reload, while JS does it without reloading

?

[late gale]

i will try both

and see what's better for me

thank you

[native tide]

Oh yeah JS would be the better option for sure

You'd have something like the order_number thing as an API instead in that case

[late gale]

but how i can select an order item like if i added an id to the <h1> tag this will remove all my order items not a certain one

[haughty turtle]

show me your html

[late gale]

ok

[haughty turtle]

just a snippet is fine

[late gale]

                    </div>
                    {% for item in order.orderitem_set.all %}
                    <div class="cart-row">
                        <div style="flex:2"><img class="row-image" src="{{item.product.image.url}}"></div>
                        <div style="flex:2"><p style="font-family: inherit;">{{item.product.name}}</p></div>
                        <div style="flex:1"><p style="font-family: inherit;">${{item.product.price|floatformat:2}}</p></div>
                        <div style="flex:1"><p class="quantity" style="font-family: inherit;">{{item.quantity}}</p></div>
                        <div style="flex:1"><p>${{item.get_total|floatformat:2}}</p></div>
                        <div style="flex:1">
                        <a class="btn btn-sm btn-dark" href="{% url 'Products' item.product.id %}" style="font-family: inherit;">Update</a>
                        </div>
                        <div style="flex:1">
                            <a class="btn btn-sm btn-danger" style="font-family: inherit;" href="{% url 'Products_Delete' item.product.id %}">Remove</a>

                        </div>
                    </div>
                    {% endfor %}

there is the part

                            <a class="btn btn-sm btn-danger" style="font-family: inherit;" href="{% url 'Products_Delete' item.product.id %}">Remove</a>

thats the remove btn

hope u get what i am trying to say

[haughty turtle]

you need to loop through all of your remove buttons and add a eventlistener

[late gale]

oh that might work

let me try

[haughty turtle]

on click then grab its parent element

    for ( let l = 0; l < pwLength; l++) {
        document.querySelectorAll('.cart_trash')[l].addEventListener('click', function() {
            this.parentElement.remove();
            localStorage.removeItem(this.parentElement.getAttribute('id').replace(/_/g, " "))
            let totalC = parseFloat( parseFloat(document.querySelector('#total_cost').innerHTML.replace(/[^.\d]/g, '')).toFixed(2) - parseFloat(this.parentElement.childNodes[6].innerHTML.replace(/[^.\d]/g, '')).toFixed(2) ).toFixed(2);
            document.querySelector('#total_cost').innerHTML = `Total: $${totalC}`;
            if ( cart_count () < 1 ) {
                document.querySelector('#overlay_wrapper').style.display = 'none'
            }
        });
    }```

this is an example that I just recently used

[late gale]

oh ok let me see

[haughty turtle]

it has some extra stuff in there but just focus on the loop, the eventlistener, and this grabs the object that your item is in get the parent and delete it.

check if the item count in the cart is 0 to then exit out of the cart display

update new total price

[tacit sleet]

Okay I'm admittedly new to Django but am a bit baffled on this one. I have django running in docker. Template loads fine. I have a file called main.js in my static folder that 404s when the template tries to load it. Works perfectly in my 'prod' docker-compose using nginx and gunicorn, but running in the dev server it 404s. What the am I missing?

@haughty turtle the item isnt removed yet

there is only one remove button i think no loop needed

look

                            <button type="submit" id="button" value="Remove" class="btn btn-sm btn-danger"></button>

                        </div>
                    </div>
                    {% endfor %}
                    <script>
                        document.getElementById("button").addEventListener('click', function(){
                            var order_item = document.getElementById("order_item").remove()
                        })
                    </script>

it just removed the button .

or wait

oh it worked @haughty turtle but the problem is if i refreshed it came back again

[haughty turtle]

because you have your button wrapped in a div

so you have to remove the parent of the parent of your button

@late gale have to head out

[tacit sleet]

I grabbed #☕help-coffee

If anyone knows django and has a moment

[haughty turtle]

also you need a loop because you have a button for every item {% for item in order.orderitem_set.all %}

[late gale]

it removed the item but it comes back on refresh

oh i believe u are right

[haughty turtle]

because of the for loop, on refresh it refresh everything

[late gale]

i tried to click on the second button but not worked

[haughty turtle]

so you have make sure to verify where you are grabbing your items from {% for item in order.orderitem_set.all %}

[late gale]

and how i gonna loop in this tbh

[haughty turtle]

on refresh you are setting displaying all items from django again

[grizzled sand]

Hello everyone. Could i represent this function view to class based ListView?
I've confused because in django documentation says, ListView - Each generic view needs to know what model it will be acting upon. This is provided using the model attribute.
as i understand with model = My_model, but if i want add more the one model to this view, how can i do that?

Thanks!

def index(request):
    '''
    Function for display homepage

I have to head out wife is waiting for me, instead of using django to display each item in your cart try to use js

[late gale]

but i want it to be deleted forall

ooh np take care

[haughty turtle]

So when a user clicks add to cart you send the items they added over to Django? @late gale

[late gale]

yes

thats why i need to use django to delete

[haughty turtle]

@late gale are you dealing with registered users?

[snow sierra]

let me know why here is not request.POST['fname'] instead of request['fname'] .. etc.. ????

[wary turret]

Hello! I'm looking to start a personal project that needs a webserver backend. Just a few endpoints and some light DB access. Is Flask still the way to go? or is there something new/interesting I should check out?

[haughty turtle]

@snow sierra because I sent a POST through fetch in JS,

My items was attached into it's body as JSON

[snow sierra]

oops sorry, yes ( request = json.loads(request.body.decode('utf-8')) )

[late gale]

@haughty turtle nope guest users

[haughty turtle]

If you are using guest user then no reason to send this over to Django

[late gale]

i did i can remove all the orders using django from the remove button but cant remove specific one

[haughty turtle]

Could be due to the cascade on delete, show your model, but what I want to say is that if you are logging a user in then you shouldn't be sending this over to Django until the user is ready to finalize the purchase then you cross reference your items from your models to make sure they are paying the correct price.

[trim star]

I am trying to run unit tests in django python3 manage.py tests and I get the following error:

django.contrib.messages.api.MessageFailure: You cannot add messages without installing django.contrib.messages.middleware.MessageMiddleware

And messages is in INSTALLED_APPS

and MIDDLEWARE

[haughty turtle]

Even then if you log a user, me personally I would save this as a JSON through the use of fetch and save it under my User model. Then I would be able to grab it and loop through it. Even then point being you will still need JS to provide better UX, the way you are going would require a reload. @late gale

The way you are displaying your items in your HTML requires a reload for changes to take effect. Not recommended

[vestal hound]

@grizzled sand that doesn’t really work... it has to be one model per view.

can be nested thoughthis

[gaunt marlin]

@trim star did you add django.contrib.messages.middleware.MessageMiddleware' to your MIDDLEWARE settings ? https://docs.djangoproject.com/en/3.1/topics/http/middleware/#activating-middleware

i presume that you also had django.contrib.messages in your INSTALLED_APPS

[twilit needle]

BRUH no thats against discord's tos but dont worry I wont report you

import axios from 'axios';
import pixStore from '../redux/store';

axios.defaults.xsrfHeaderName = "X-CSRFToken"
axios.defaults.xsrfCookieName = 'csrftoken'
axios.defaults.headers.common['Authorization'] = JSON.parse(pixStore.getState().token);

export default axios;```

I did this to make axios default headers but still my requests are failing because they arent authorized

the api says I need the auth token in the header

But I already have it, right?

What am I doing wrong here? pls help me

I console.logged JSON.parse(pixStore.getState().token) Its the correct token

[gaunt marlin]

most api will also following the format of "Authorization: Bearer <token>"

like this?

@gaunt marlin

[gaunt marlin]

yeah

[twilit needle]

or the <>

is required?

[gaunt marlin]

no need for <>

[twilit needle]

okayb thanks Ill try it

[gaunt marlin]

i just use it to tell it's for token

[twilit needle]

okay

still same error..

idk why

does 401 indicate something else

[gaunt marlin]

401 is unauthorized https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/401#:~:text=The HTTP 401 Unauthorized client,credentials for the target resource.&text=This status is similar to,this case%2C authentication is possible.

[twilit needle]

function logoutUser() {
        axios.post('/api/logout/')
            .then(() => {
                dispatch({type: "CLEAR_AUTH"});
                <Redirect to='/login/' />
            })
            .catch(error => {console.log(error)});

    }```

[karmic egret]

can anyone suggest me some helpful tutorial for flask-security

[twilit needle]

this is how I make the request

and I import axios from here

import axios from '../../tools/csrfConfig';``` where I defined the default headers

anything wrong here?

[gaunt marlin]

which system are you using for authentication?

firebase? jwt?

[twilit needle]

token auth django

[trim star]

Yes I did

[twilit needle]

my other endpoints which dont need authentication are fine

[gaunt marlin]

i think you mean authToken of DRF, not Django(django don't have it)

@twilit needle then i think you would need to use the format of "Authorization: Token <token>" https://www.django-rest-framework.org/api-guide/authentication/#tokenauthentication
as you see from the example

Authorization: Token 9944b09199c62bcf9418ad846dd0e4bbdfc6ee4b

jwt you use Bearer, auth token you use Token

[twilit needle]

yeah the rest framework thing

i meant

[glass badger]

Can Django work as a sub-domain to a SquareSpace website?

[twilit needle]

axios.defaults.headers.common['Authorization'] = 'Authorization: Token ' + JSON.parse(pixStore.getState().token);``` am trying this @gaunt marlin

[gaunt marlin]

@twilit needle don't do that, you don't need the after authorization

[twilit needle]

okay

lol

axios.defaults.headers.common['Authorization'] = 'Authorization ' + JSON.parse(pixStore.getState().token);```

this?

it doesnt work though

same error in console

[gaunt marlin]

axios.defaults.headers.common['Authorization'] = 'Token ' + JSON.parse(pixStore.getState().token);

is ok , i don't know about axios so i guess this is the way to set header

[twilit needle]

http http://127.0.0.1:8000/hello/ 'Authorization: Token 9054f7aa9305e012b3c2300408c3dfdf390fcddf'```

I saw this example

[gaunt marlin]

yeah

did it worked though?

the api supposed to return status code of 200

[twilit needle]

yeah but it didnt

one sec

@api_view(["POST"])
@permission_classes((IsAuthenticated,))
def logout(request):
    try:
        request.user.auth_token.delete()
    except (AttributeError, Exception):
        pass
    logout(request._request)
    return Response(status=HTTP_200_OK)

this is my view

[gaunt marlin]

what did the api return?

[twilit needle]

401

not authorized

[gaunt marlin]

did you check your token? to see if it's correct?

[twilit needle]

um yes

its correct

am sure

https://simpleisbetterthancomplex.com/tutorial/2018/11/22/how-to-implement-token-authentication-using-django-rest-framework.html

am referring to this

GUESS WHAT IT WORKED

and I know why

axios.defaults.headers.common['Authorization'] = 'Token ' + JSON.parse(pixStore.getState().token);

we're supposed to do this

the Authorization: part was this

axios.defaults.headers.common['Authorization']

axios automatically passes it as a dict

so we shouldnt do Authorization:

[gaunt marlin]

well yeah that what headers.common is for

[twilit needle]

yeahh

[gaunt marlin]

set the header values

[twilit needle]

lol I was so stupid

[gaunt marlin]

so it can pack into dictionary

[gaunt marlin]

@twilit needle i suggested you this earlier but you said it returned 401 which make me confused

[twilit needle]

Ohh

sorry I think I mistook you

Maximum update depth exceeded. This can happen when a component repeatedly calls setState inside componentWillUpdate or componentDidUpdate. React limits the number of nested updates to prevent infinite loops.

now I get this error duh

when I try to login

import React from 'react';
import { Route, Redirect } from 'react-router-dom';
import {useSelector} from 'react-redux';
import {IsNull} from '../../tools/easierJavascript';

const PrivateRoute = ({component: Component, ...rest}) => {
    const user = JSON.parse(useSelector(state => state.user));
    return (
        <Route {...rest} render={props => (
            (!IsNull(user)) ? <Component {...props} /> : <Redirect to='/login/' />
        )} />
    );
};```

problem is with this

[gaunt marlin]

well that is axios error which i'm no expert in

[twilit needle]

no its reactjs error

function AppRouter () {
    return (
       <Router>
           <div className="appRouter">
                <Switch>
                  <PrivateRoute path='/app/' component={App} exact />} />
                  <Route exact path="/" render={() => (<Redirect to="/app/" />)} />
                  <AuthenticationRoute path='/login/' component={LoginMount} />
                  <AuthenticationRoute path='/register/' component={RegistrationMount} />
                </Switch>
            </div>
       </Router>
   );

So I have a router for my app

[gaunt marlin]

well react use axios to doing requests

[twilit needle]

and it has PrivateRoute components

[gaunt marlin]

oh ok got it

[twilit needle]

the private route component is running an infinite loop?

Maximum update depth exceeded. This can happen when a component repeatedly calls setState inside componentWillUpdate or componentDidUpdate. React limits the number of nested updates to prevent infinite loops.```

I got this error

nevermind

I think I solved it

I didnt json.parse the user in another component

[gaunt marlin]

@trim star i think your case might be like this https://stackoverflow.com/questions/55843504/django-messages-middleware-issue-while-testing-post-request

[iron beacon]

gn everyone

I'm kinda new to web-dev, mostly the authentication part got me confused

My question is how is token more secure then username and password authentication to REST APIs?

I'm currently developing a REST API and there's a endpoint to retrieve the user token based on its username and password.

In that case is not the same thing? If someone get your password it might aswell get your token in that way

[gaunt marlin]

@iron beacon token is to identify which user calling the api,
you first send username/password to authenticate that user is correct and give them a short live token, for example to call /profile api you would send user token instead of sending username/password again. If you want to secure from man in the middle attack(if someone stole your token), this is where SSL come in, it's use to encrypt your network traffic. If you use authentication setting up SSL is MANDATORY. TLDR: Token itself don't have any security, it just use to identify user, if you want secure then encrypt your api host with SSL

[iron beacon]

Oh, so that's why the DRF documentation mentions that you need to use HTTPS instead of HTTP when working with tokens

[gaunt marlin]

yep

@hushed barn everyone hits the point you have hit and makes silly mistakes wether you are 10 or 50 or anywhere in-between learning something new is the same for everyone. I started around that age messing with C++ and regret giving up to just pick back up on it at 23 years old. Also you should probably stop stating that you are under the age of Discord ToS might get your account suspended, either way your never to young or old to learn how to code.

[sterile peak]

I am going mad trying to work with zeep and one WSDL.. is there anyone experienced with this

@vestal dove you need to use blueprints

@feral condor Open the database in a DB viewer (SQLite browser) and see what fields were generated

Then you will know how to navigate

Anyone here who has worked with Django and ariadne? I am having a tough time implementing user authentication and want to see some example repos if you have one.

[native tide]

Hey guys... I am looking to build an application that is going to have two bits that need to work independently. One would be talking (mostly receiving) to a MQTT bus, the other one would offer a REST API to serve as an endpoint for a system downrange. I did something similar a couple years ago and then I decided to use Threading. I ran my server in one thread and web server in the other while they exchanged data throuh Queues.

I guess my question would be what would be the go-to approach for something like this today?

Thank you in advance for any advice you may give!

[haughty turtle]

Could you not also use a text file called logs and check up on it to then see when its updated and if so then read it and perform a action, as far as best practices I do not know, I have done something similar with Sockets for apps on different system, but if they are on the same seems like a log file would serve the purpose

Ah take a look at this

https://www.geeksforgeeks.org/methods-in-interprocess-communication/

@native tide

[native tide]

@haughty turtle yes, I have considered this option too.

[haughty turtle]

https://docs.python.org/3/library/ipc.html the python docs reference the use of signal or mmap modules for IPC on same machine. Might be worth taking a look at

[thin dome]

anyone here?

i want help

with my django project

i am facing a error

error is '<module 'home.urls' from 'D:\\Programs\\Hello\\home\\urls.py'>' does not appear to have any patterns in it. If you see valid patterns in the file then the issue is probably caused by a circular import.

[verbal snow]

For some reason i get this when going to the django admin panel
https://haste.powercord.dev/wenosesone

[thin dome]

are u reponding to me?

[verbal snow]

How would I respond to you with and admin panel error?

[thin dome]

sorry

[native tide]

@thin dome show us urls.py

[thin dome]

can u help me?

ok my app one or project one? @native tide

[native tide]

home\urls.py

[thin dome]

ok

from django.urls import path
from home import views

urlpatterns = [
    path("", views.index, name="home")
]

[native tide]

@verbal snow 'User' object has no attribute 'pk' What is your User object in this case?

@thin dome did you register you app in settings.py

[thin dome]

how to? in tutorial he doent open settings.py @native tide

i m learning so idk that error and other stuff

[native tide]

So open settings.py and show me INSTALLED_APPS

[thin dome]

i only now how to register templates

ok

[verbal snow]

I have a separate user model than the admin user model. Which one?

[trim star]

Yes I had those items but for some reason when I run the tests it fails

[thin dome]

    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
]``` @native tide

[native tide]

what is your appname? is it home? If so, add 'home` to installed_apps

[thin dome]

yes

how?

django.contrib.home?

[native tide]

@verbal snow Do you know what file that error is in, User object has no attribute pk?

@thin dome No, just 'home'

[thin dome]

ok

[native tide]

The name of the app

[thin dome]

    'home'
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
]```

like this?

[native tide]

well, no, it's a list

you missed something out

[thin dome]

then how?

[native tide]

the clue is

Somebody help me:
https://hastebin.com/ocomonusuq.sql

it's a list

[thin dome]

im starting django please help me

pleaseeeeeee

[verbal snow]

Looks like a django file itself

Looks like admin logs

Logs.py of admin

[native tide]

@thin dome Yeah, that's not a django problem, that's a basic python problem. Give me an example of a list.

[thin dome]

a = [1,1,2,2]

thats a list

[native tide]

Now compare that to your INSTALLED_APPS

[thin dome]

['home']?

[native tide]

@verbal snow I'm gonna need more information than the error, maybe you're calling .pk incorrectly? I don't know

[verbal snow]

I'm not calling it

This is a django file calling it

[native tide]

Ok, do you have a custom User model?

[thin dome]

is it ['home']?

[verbal snow]

No

[thin dome]

help mememememememememeeeeeee

[native tide]

@verbal snow So what are your models looking like?

Flask or Django. Which is best?

And WHy?

[thin dome]

flask for small apps django for big

[native tide]

@thin dome You just gave me an example of the list. Now compare it to INSTALLED_APPS.

[native tide]

Learning Django will be fine?

[thin dome]

please nobody torched me this much

yes

[native tide]

I'm asking this question so you will learn

Instead of just giving the answer

[thin dome]

i am learning it too @native tide

[native tide]

you need a comma after 'home'

[thin dome]

ok nice mentor

[native tide]

Ohk Thank You.

so I asked you to compare it to your list so that you'd see that you need a comma

[thin dome]

is this right?

    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',```

[native tide]

what type is INSTALLED_APPS

Can we do the things which JS can do like adding animations to button with django?

@native tide Not really, unless you use CSS animations

Django is a backend framework

[thin dome]

INSTALLED APPS is list

[native tide]

exactly... so why are you doing this? ['home']

Ohk and can we render js(frontend js) with django.

yep

within a html?

mhm

like having a js file for html.

and we render html so that js is also rendered.

[thin dome]

    'home',
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
]```

[native tide]

You mean <script> within html? Yea

@thin dome that's right

[native tide]

Yeah and having index.js linked with html

[thin dome]

but i am getting this error again

[native tide]

Then its fine i can then make a nice frontend too.

[untold topaz]

Anyone here familiar with XML and XML Queries??

[native tide]

@thin dome then you need to sort out the urls.py in your root directory

[verbal snow]

https://haste.powercord.dev/iluhibujuk

[native tide]

Do you have any project with django like having a text box linked with sql?

[verbal snow]

this is my models

but the error looks like it has to do with the admin User model

I have my own user model

[thin dome]

this is my rootROOT_URLCONF = 'Hello.urls'

[verbal snow]

But it is not sub classing the admin one

[native tide]

@verbal snow Possibly, in your admin model are you setting this?:

unique_id = models.AutoField(primary_key=True)```

[native tide]

@native tide

@thin dome No, open up the urls.py , you should have 2

Want to see how the code looks like.

[thin dome]

yes

[native tide]

For me?

[thin dome]

this is my hello url=```from django.contrib import admin
from django.urls import path,include

urlpatterns = [
path('admin/', admin.site.urls),
path('', include('home.urls'))
]

no i was saying it to @native tide

[native tide]

Ohk

[thin dome]

u indian?

[native tide]

Yes.

[simple surge]

hi

[verbal snow]

What admin model?

[simple surge]

I`m, luqm,an

[verbal snow]

I'm not editing any admin models, nor am I subclassing any of them

[thin dome]

@native tide

[native tide]

@verbal snow But you made your own admin model, right?

[native tide]

Why are you asking btw?

[thin dome]

no my many frnds name is vishal

in india

[native tide]

Ahh i see.

Hmm Vishal is an Indian name.

[thin dome]

yes

[verbal snow]

No

Thats what I've been trying to say

[thin dome]

man help meeeeeeeeeeeeee

[verbal snow]

I'm not doing anything with any admin models

[thin dome]

@verbal snow can u help me?

[verbal snow]

What is it?

[thin dome]

mproperlyConfigured: The included URLconf '<module 'home.urls' from 'D:\Programs\Hello\home\urls.py'>' does not appear to have any patterns in it. If you see valid patterns in the file then the issue is probably caused by a circular import.

this error

[verbal snow]

https://stackoverflow.com/questions/3011179/django-the-included-urlconf-doesnt-have-any-patterns-in-it

[thin dome]

i have gone to that website

i cant understand anything

[native tide]

@thin dome give your urls names

name="url_name"

[thin dome]

can u come to vc i will screen share

[native tide]

no

[thin dome]

ok

is this what u want

from django.urls import path
from home import views

urlpatterns = [
    path("", views.index, name="home")
]

this is my app urls

[native tide]

give it a path, like 'example/' and see what the issue is then

[thin dome]

i was creating fornt page

means if there is just url then it will go home page

so its just " "

[native tide]

Ok, it was just a debugging thing, what's your views.index?

[thin dome]

# Create your views here.
def index(request):
    return HttpResponse("this is homepage")```

this is my views.py

[native tide]

So if you want it in the homepage, why don't you just do
path("", views.index(whatever the route is), name="homepage") in your main urls.py

[thin dome]

:[ i cant understand

i am just following tutorial

[verbal snow]

whats so hard to understand

[thin dome]

@native tide

@native tide your are bestttttttt guy i ever met in django field

[native tide]

so is your issue fixed now?

[thin dome]

yes

but include doent work

but i think thats ok

this is my main urls```from django.contrib import admin
from django.urls import path,include
from home import views

urlpatterns = [
path('admin/', admin.site.urls),
path("", views.index, name="homepage"),
]

[native tide]

because in your main urls.py, you are specifying the routes for your apps.

so

path("products/", include(products.urls))```
will setup a url for `site/products`

Then in your `products` app you can do:

```py
path("product-1/", views.index, name="product-1")

which is for the url site/products/product-1/

So if you have an app, make sure it has it's own url.

[thin dome]

ok can i dm u if i face error?

or no?

[native tide]

use google

[thin dome]

ok

[native tide]

Can we do register and login logic from a single route in django?

@native tide yep

@native tide give me some hints

how would you do that?

I want home address to be redirected to login/register page

can't you just have 2 forms which do different things when submitted

when they are not logged in or registered

[native tide]

oh right

Can I redirect to two different pages? (login and home) from a single (home address) route?

@native tide

why not

sure

again, I need hint for that

that would be awesome

anyway, are you working on ML project sir?

well, if Login form is submitted, redirect to x, if signup form is submitted, redirect to y

not atm but I'd be interested to hear about it

but, the project urls.py file would give me an error if I set two app with same route ('') right?

[haughty turtle]

In your view @native tide

In your urls.py it would grab the first one that matches

[native tide]

so, how do I do that whole thing working?

@native tide Oh I misunderstood that question

say, I have an app for home route leading to dashboard with an empty route in projects, urls.py

You can have one route, have a view, that view can take information from the request (which specifies stuff, like login or register and THEN redirect you to another route)

and same for login page (app)

[haughty turtle]

The norm is that you send a user to login and from there you place a link that sends them to the register page

@native tide

[native tide]

so, the url should be different?

Well can you explain in layman terms what you want to achieve?

[haughty turtle]

He just wants to create a normal login registration page, but the thing is @native tide that you would have no way to find out if the user wants to login or register without them clicking a link for either or

[native tide]

I am actually trying to move the static website which was designed with html/css, now, I am trying to add blog on it. but, I designed the login/register form in a single page

then, I also don't want the login/register page routes to be url/login or url/register

got me?

[haughty turtle]

Well how would you know what a user wants to do ?

[native tide]

wdym?

[haughty turtle]

You have to have a link saying to either register or login, from there you can use JS to display the either form depending on which was clicked

You want the log in and register to be on the same page correct, you can choose to display a log in form and have a Register Account link under the form

Upon clicking the link with JS you can hide the display of the login form and show the sign up one

You send a fetch POST to the server and specify wether it's a Login or Signup and handle that in your views.

[native tide]

Still don't know what he wants lol. You can have the login/register on the same page, and if LoginForm.is_valid() you can redirect to (/homepage/) and you can do the same for the RegisterForm, it's got nothing to do with the routes

Can I DM one of you guys to show what I am trying to make?

[native tide]

I have created a page like this

[haughty turtle]

And you are struggling to toggle which forms to display?

[native tide]

nop

I am struggling to think how will I apply that in django

[haughty turtle]

in Django all you need is a view to send a POST request through fecth in JS that contains your form data and then type of form sent wether Login or Register.. with that you either register the user and log them in or just log them in and then send them to the dashboard

[native tide]

I feel like I am getting it finally

prolly makes sense when I implicate that

[tacit sleet]

Yesterday someone that was helping me with a Django issue mentioned that they hadn't done Django in a while - is that because Django isn't the best option for a python frontend and I should consider something else? I'm building a portal a user will oauth into to manage some settings (via API calls to another service) and take a subscription payment via Stripe

[native tide]

are you good at JS?

[tacit sleet]

Writing JS for this is my first real exposure to it, so no

[native tide]

php?

[tacit sleet]

I'd prefer not - I'm familiar enough to know I'm not a huge fan of PHP

if I did something other than python it'd be JS, but that's a bigger undertaking since I'd have so much to learn

If the answer is python is a bad option and just go learn JS I'm okay with that

[native tide]

I am no expert but Python isn't bad. But, if you were familiar with JS, I would suggest JS. But, if you have to start from the beginning, it doesn't worth

because django is capable of doing your things

[tacit sleet]

thanks!

[haughty turtle]

Django for backend, JS frontend

JS is built into the browser client side so it allows for real time changes in the browser while you secure your website and any sensitive info with Django and it's backend which handles any request sent to your server

[tacit sleet]

yeah that's what I'm doing now. Using JS to do the event handling for button clicks and passing things to django for payment/etc.

[native tide]

in django how to add like a global filter to a model. So everytime this model is called, that filter is applied to it before.

[tacit sleet]

I just wanted to make sure I shouldn't go to an all JS solution like node or something

[haughty turtle]

https://www.google.com/amp/s/clever-solution.com/blog/django-vs-node-js-choose-the-most-suitable-web-app-development-technology/amp @tacit sleet

Seems like Django offers better security and faster deployment then node.js

[quick cargo]

thats low key comparing an entire language to a framework tho

[surreal nest]

Hi guys

I have a question about the http protocole

Let’s say a client made a request and the server responded back

How does the client know how to ask new requests depending of the servers’s answer ?

[haughty turtle]

How are you sending out the request ?

@surreal nest

[surreal nest]

with a tcp connection

With the socket module

[surreal nest]

Nvm, seems that the client make himself the new request depending on the response of the server

[native tide]

@native tide what's your ML project btw?

[minor horizon]

I just have created a fast api running in a docker container. It shows that it's running, but it's absolutely not responding to my posts. Any ideas?

This is the dockerfile:

FROM python:3.6.9-alpine

WORKDIR /fapi

COPY . /fapi

RUN pip install --upgrade pip setuptools wheel
RUN pip install -r /fapi/requirements.txt

EXPOSE 8000

CMD [ "uvicorn", "api:app" ]

And I run it via: docker run -p 8000:8000 fapi:test

And this is the output:

INFO:     Started server process [1]
INFO:     Waiting for application startup.
INFO:     Application startup complete.
INFO:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)

[native monolith]

have you tried localhost?

curl - X POST localhost:8000/

[minor horizon]

Yea I have tried that:

And no logs/stdout in docker logs

[native monolith]

is your app working on this port ?

[minor horizon]

Yep,

[native monolith]

🤔

maybe container has different addres

localhost is inside I think

[minor horizon]

Sorry, what do you mean by address?

[native monolith]

127.0.0.1 aka local host is reachable as localhost inside, but im not sure

[minor horizon]

I would love to if you help me, I'm kinda stuck here

Hmm

I just tried 0.0.0.0, not working either

when I run it via like uvicorn api:app, it works well. Without docker

PORTS seems right, right?

curl -X GET 0.0.0.0:8000/ i get the error curl: (56) Recv failure: Connection reset by peer

[native monolith]

try adding output ip

https://forums.docker.com/t/how-to-expose-port-on-running-container/3252/10

[minor horizon]

This worker, thanks! But I doesn't fit for me yet, I need to understand this

What if I don't want to use host's network, isn't the isolating containers best practice?

[native monolith]

I would tell you If I knew

[minor horizon]

I see. Thanks a lot!

[native tide]

Has anybody deployed a django + react application before? What hosting service did you use? Please let me know 🙂

[haughty turtle]

Would it be any different than a normal setup?

[native tide]

I don't know what the "normal" setup is

[haughty turtle]

check out linode

[native tide]

I feel like linode doesn't have the relevant reputation to be able to discuss on a resume...

Compared to something like AWS or GCP

but I've heard AWS is not for beginners

so I think I'll use heroku or GCP

or digital ocean. but i've not heard much about that

[haughty turtle]

Umm what's the difference between Linode and AWS?

Aren't they both VPS

@native tide

[short nacelle]

AWS is awesome, use S3 Buckets to host static websites

[thin dome]

how to use render?

[gaunt marlin]

render of Django?

[thin dome]

yes

how to use it

[humble rapids]

I know this is unrelated. But does anyone here have a good understanding of the library 'pyglet' in python and would be willing to help me out?

[native tide]

trying to implement a linear regression problem solution in my webapp

[gaunt marlin]

@thin dome render() is to use within your app views, it render which html template to return with values passing to that template. To read more on the function you can see this https://docs.djangoproject.com/en/3.1/topics/http/shortcuts/#render
If you haven't done the django tutorial pages it mention on how to use it https://docs.djangoproject.com/en/3.1/intro/tutorial03/#write-views-that-actually-do-something

[thin dome]

ya i solved it

[pseudo marsh]

Hey there, I needed some help with html

on this page
https://leetcode.com/problems/poor-pigs/

Inspect element, and you will find a div tag like this:
<div class = "content__u3I1 question-content__JfgR" >

I'm not so good with web development, Could someone help me figure out where this class = "content__u3I1 question-content__JfgR"is?
I want to copy the question description from the page and format it just like it is formatted on leetcode

I tried looking at the link rel stylesheets thing in the <head> tag but I couldn't figure it out

[vestal hound]

it's automatically generated by some frontend framework

[karmic egret]

can anyone suggest me helpful videos and article for flask security, especially on how can I manage and personifize my own login, logout, etc websites

[pseudo marsh]

well how do I format the question the way they did on my page then?

[vestal hound]

...is that even legal?

[pseudo marsh]

and how'd you tell it was automatically generated

oh it isn't?

[vestal hound]

I would imagine the CSS and HTML protected by copyright

shrug is my guess

[pseudo marsh]

that sounds really weird

[vestal hound]

nobody calls their CSS classes "content_U3I1"

anyway

[pseudo marsh]

lol that was the only reason?

[vestal hound]

you mean replicate the whole page?

or just the question?

[pseudo marsh]

No just the question

Also I'll brb in a few mins

[rustic pebble]

Frontend framework for sure, React does that

[pseudo marsh]

will not be able to respond till thhen

[pseudo marsh]

aight I'm back

[pseudo marsh]

well just the question, is that doable?

[pseudo marsh]

Uh is there an easy way to replicate it then?

[rustic pebble]

Yes

Learn react

[pseudo marsh]

very insightful

thanks for the time anyway.

[rustic pebble]

Well React is a huge frontend framework, there is nothing easy going with it lmao

@pseudo marsh

[pseudo marsh]

I mean

I didn't intend to have it identical, just something that looked similarly formatted to that piece of text
I don't think that would require me to invest time into react imo

[vestal hound]

define "similarly formatted"

[pseudo marsh]

For now I'll just do with the bareblocks html part of it and add some backticks in there to make a few words stand out and that'll suffice

Have a similar look

[rustic pebble]

You cannot replicate SPA-like behavior without a SPA framework and as all things, learning one takes time and devotion

[vestal hound]

not specific enough

[pseudo marsh]

yeah I didn't anticipate a task as simple as this would require all that effort, is all

[vestal hound]

I have no idea what you mean by the "look"

[rustic pebble]

Do you mean by how the classnames appear?

Or by the styling of the web page?

[vestal hound]

which is a pretty subjective thing

[rustic pebble]

ye

[vestal hound]

this, but which aspect of the styling?

[pseudo marsh]

what I mean is

I have this

on my screen

[rustic pebble]

Yes

[pseudo marsh]

I just wanted to have this piece of text somewhere else

and for it to have the same look as this

[rustic pebble]

That's styling and has nothing to do with react

[vestal hound]

basic CSS

[rustic pebble]

or frameworks

yup

[vestal hound]

do you know CSS?

[pseudo marsh]

Right, and I figured the styling depended on the class name which was kinda what I think I asked originally

[vestal hound]

hm.

do you know how CSS classes work?

[pseudo marsh]

Yeah a bit, and I figured the style for this was coming from the css class I asked about earlier?

[rustic pebble]

There is no css class actually, you create an element, you create a class attribute for that HTML element then you can directly edit that element's style by using its class name as an identifier in css

So basically

[pseudo marsh]

ie, I wanted the definition for the class so I coudl have a similar wstyle

[rustic pebble]

<p class="test">this is a test paragraph</p>

This has a class with the name of test

in order to style that object you can do 2 things

either in-line styling by adding a style attribute

[vestal hound]

ah, then not really

in this specific case

those classes are for content projection

not for styling the question text itself

[rustic pebble]

or by creating a css file and doing the following

.test {
  /* add style here
}

[pseudo marsh]

I understand that, which was why
<div class = "content__u3I1 question-content__JfgR" >
I was looking for where "content__u3I1 question-content__JfgR" was defined

oh

[rustic pebble]

that's for content projections yet

it probably inherits style from a parent element

[pseudo marsh]

so so whwere's the styling for the question text?

right

[vestal hound]

p sure it isn't even a custom style

just HTML

and a cursory examination of the HTML appears to bear that out

[pseudo marsh]

oh right

wait what's the difference between

content projections and well, the style for the question being displayed?

[vestal hound]

content projection basically means

dynamically creating content.

for example

workflow might be like

1. fetch question data from DB
2. parse question data
3. render question data into its slot <- this is content projection

styling affects the process of rendering i.e. what it looks like

as opposed to what it is

[pseudo marsh]

content projection is just the 3rd point in that list, is that what you meant by the arrow?

[vestal hound]

so the classes you originally talked about can be thought of as internal bookkeeping data so the framework "remembers" where the content should be

on the other hand, styles are about, given certain content, what it should look like

[vestal hound]

yes

and

that's basically a bunch of strong, code, ol etc. tags.

[pseudo marsh]

oh so like, content projections is for structuring the page
styling is for actually formatting individual parts of the structure, did I understand that right?

[vestal hound]

something like that

content projection is a HTML thing

[pseudo marsh]

and styling is a css thing, yeah?

well I guess that makes sense

Thank you both of you 👍

[vestal hound]

yw

[vestal hound]

yes, but in this case

the CSS is not really relevant

it's just HTML tags

look at the HTML generated and you can tell

[pseudo marsh]

oh right

so I was able to copy just the html part of it and I got this

Which looks just the same

right, this was so simple and I'd been struggling for so long

thank you 🙂

[vestal hound]

yw! 👋

[native monolith]

what is general method for returning results to user from backend ?

new route? access to resource? other?

[vestal hound]

you could return an ID and check periodically

or use WebSockets

or SSEs

you mean like

delayed right

[native monolith]

yes, return image after x time

id? so what you mean by id?

[vestal hound]

return an ID

that lets the client do a separate GET request

then the client polls periodically

[native monolith]

so I redirect him to template and pass ID ?

or js and same page

[vestal hound]

up to you

[native monolith]

thats why I asked for general case 😄

[vestal hound]

it is literally up to you

there is no general case here

that said, for polling you would at least need some JS in either case

even if you're not running a SPA

[native monolith]

yes yes thanks 😄

I also wonder how to make upload progress bar 🤔 , since I am runnig local I do no see when upload happens

is it when I click submit or when it is sending post request?

[vestal hound]

hm you'd need JS for this

[native monolith]

i rephrase question

[vestal hound]

or do you mean like

on the backend?

sorry I don't really understand

[native monolith]

File upload happens at POST request or GET in FORM input?

[vestal hound]

POST

[native monolith]

[vestal hound]

wait

why would there be a GET

[native monolith]

page without post 😄

I run js here and do basic validation then redirect to page with only POST

[vestal hound]

but your form submission is still a POST, right

[native monolith]

yes, I get files with POST

[vestal hound]

you mean upload?

[native monolith]

yes

Form is on GET page, and redirects to POST

  <form action='{{ url_for("validate_image") }}'
        method="POST" enctype="multipart/form-data"
        onchange="ValidateFileIfImage()"  >
    ...
    <button id="submitBt" type="submit" class="btn btn-primary">Confirm</button>

[grizzled sand]

@vestal hound Hm it works.
You just need define get_context_data in your view.

        context = super(IndexListView, self).get_context_data(**kwargs)
        context['team_list'] = Team.published.all()
        context['servicesPackages_list'] = ServicesPackage.published.all()
        return context ```

[vestal hound]

huh what works

do I need to expose port in docker?

@leaden perch if you have a question just ask, someone with knowledge in flask will answer

[karmic egret]

how do I get over the original template , and set up my own template for login, logout, etc in flask security

I mean I did not set up any route yet in my program,

yet this page can show up

[past cipher]

you must of already created that page

and why use flask-security

why not flask login ?

Here is a login I created a month or two back for a digital store:

@karmic egret

HTML template:

@past cipher What is the major difference between flask security and flask login

Because my teacher suggest me to us flask security

[past cipher]

security is dead I believe unless its started being maintained again

[karmic egret]

okay, thanks

hello guys, I need help in #help-mushroom

Can someone help me out with a feature in Django? I wanted to implement a so called "save for later" or "pins" feature to my blogs app that will save that post from that user and display it to a specific template called "pins" (just like on instagram, the save button). I'd appreciate it, thanks!

[past cipher]

store the post id in the database and then call it on the saved later page
