I have a model in Django that has a file field and I want to export all the files associated with a Foreign Key associated to that model. (It's a contract model that has an Event Foreign Key)
How should I go about doing that?

[lime frigate]

I 'm starting to learn django. But when i create a website and run python manage.py runserver

It gives refuse to connect

What's the problem?

Or should i setup anything?

[jade lark]

python manage.py runserver 0.0.0.0:8000 or 0.0.0.0 (cannot remember off the top of my head atm)

[lime frigate]

Why isit so? I'm just curios

Curious*

Still refused to connect

[jade lark]

Did you try both variants of the command?

python manage.py runserver 0.0.0.0:8000 is the command. I just looked it up to confirm

[lime frigate]

Hold up my bad lmao

I typed sthg like 127.0.0.1/8000

So dumb of me

Sorry guys

[jade lark]

No worries man at least you got it figured

Can someone help me create some dependent drwopdowns in Flask?

I want to create dependent dropdown forms for Country, State, District, City

    return Response(serializer.data)
```  i'm using this view for pagination but if i visit to this and then come back  to database it deletes the object from database  automatically at visit

can't i used function based views for work like pagination deleting updating

@eternal blade the g0d is on9 wow

[eternal blade]

You need to check if the request is a GET or DELETE request

[dusk portal]

umm

can't i do with browser

wait lemme try with postman

[dusk portal]

then too it's deleting in postman too @eternal blade

umm func based view for rest framework ig sucks

[cobalt tartan]

thanksk mate!

Hey, any recommendations for a reporting app for django?

Pretty much would like to build queries and save reports that users can run again but with built in ability to export to csv, excel, pdf

[manic frost]

TIL that TypeScript allows you to express this:

[violet briar]

I don't really know if I should be using FastAPI or django for my graphene graphQL API, I come from a flask background so I am into more simple and open web frameworks, the thing is, I was not able to wire-up the database properly with FastAPI because I had to use SQLalchemy which is pretty painful and had to use graphql-sqlalchemy which tries to mimic the API of graphene-django, but, it's full of bugs and overall not so great to use

besides all that, the biggest problem I am facing is that I can't find any good learning resources to learn how to implement a graphQL API with fastAPI, all the quality tutorials were about graphene-django

but the struct i dont can upload

i has the proyect into a path src

[eternal blade]

You are deleting the post model regardless if the request is a GET request or a DELETE request, add an if statement to see if the request is GET if it is return the data, if the request is a DELETE request delete the post

What is the difference between python manage.py migrate and make
migrations ?

[ionic raft]

makemigrations is (from my limited understanding) about qualifying your changes, checking model for readiness, determining the upgrades to DB etc. It will serve warnings when there are missing elements. Migrate is the application to the DB.

[ionic raft]

Site logo needs to be

#sitelogi_ani...```
You're calling id and thus need # in the css

[lime frigate]

Still don't get it hehe what will happen if i use migrate insted of makemigrations

[ionic raft]

YOu need to use both. Makemigrations and THEN migrate

[inland oak]

makemigrations creates files which contain instructions to migrate db
migrate applies those files of migrations to your DB

[lime frigate]

Isit something like git add then git push

[ionic raft]

makemigrations = prepare
migrate = implement

[ionic raft]

Yes...kind of. A good comparison

[lime frigate]

Ok now i got it, thanksss😋

[ionic raft]

Oh and tip...git add/commit/push BEFORE you make changes to DB. Rolling back a DB can be a nightmare when it goes wrong

I've had a couple of instances where I used the wrong default on a type of field and things have gone VERY badly

I learned the hard way...
Updating the model? USE VERSION CONTROL!!!!

😄

[lime frigate]

What's rolling back?

[ionic raft]

Going to last working version...Like when you do something, and when you try and run things you get error messages that are really obscure that you KNOW related to something you did wrong in the change to the model

changing the DB is the riskiest change in my limited experience. git is the saviour...so long as you save right before the model change.

[lime frigate]

Change as in?

Adding data or adding column

[ionic raft]

If I change the application or presentation layer...easy to fix...but the DB...that's a whole different ball game.
If you change fields, their types, attributes, adding fields...

[ionic raft]

Pretty much. My rule is...If I mess with the model...I save that shit

[lime frigate]

Ooo ok now i got it.. thanks for the heads-up😉

[ionic raft]

But then, the model entity diagram for my web app project is a bit of a beast...

[lime frigate]

Man that's complicated for a beginner like me haha

[ionic raft]

19 tables...over 11k lines of python and 9k+ lines of html/css.
Yes...I too was a beginner...April 16, 2021. Four months later...and that's the result..

[lime frigate]

I like ur efffort keep it up

[ionic raft]

Apr 15 I did not know anything about Python.

[lime frigate]

Did u save it on github?

[ionic raft]

Couldn't stop if I tried...
I have a private repo on github for this.

About 1-2 weeks from first deployment to production on Linode. Assuming all goes as planned

[lime frigate]

Oooo i c

R u working ?

Or r u just plainly practising

[ionic raft]

I had the blessing of a few months of pause after a really big business project successfully delivered in March to client. Been filling the time until new contracts start in Sep. I'm a business consultant

Had the idea for this web app....and decided to learn how to code Python

[lime frigate]

Ooooo

So what is exactly ur job?

Software engineer,

?

[ionic raft]

Hmmm...I train and mentor organizations on how to improve how they work, how they collaborate. LanesFlow is the web app I'm building and is about automating what I do for a living, have been doing for 25 years.
Think, business consultant in an app...here's the dashboard of the web application...

[lime frigate]

Ooo so this is ur website?

[ionic raft]

Yep

[lime frigate]

And u use it for the purpose of business consulting?

[ionic raft]

The idea is that any business can use it for improving their processes.

[lime frigate]

Respect 🙌

[ionic raft]

The first subscription tier is free. You get access to most of the tools, just limited...

[lime frigate]

Hmmm my desired job is actually setting up website for companies

But urs is great too

[ionic raft]

I love what I do. LanesFlow is about making copies of me and what I do. 😄

I have limited bandwidth.

[ionic raft]

What are you currently learning?

[native tide]

oh ok

[lime frigate]

I know reactjs, php and java and basics of python so i looking forward to extend my knowledge in using django 😀

[ionic raft]

That's a great start!
I've been saving React/JS for next. The 8th app for LanesFlow is a diagramming app.
Django is amazing. It will be a great experience for you I'm sure. A bit complex at first, but once you get used to the layout/approach it really speeds up

[lime frigate]

But i find that it's quite similar to express js

So i think it will be a smooth journey

[ionic raft]

I'm not familiar with that. I actually have no knowledge of JS as yet. BUT, I also had no knowledge of Python either.

I've been 6 weeks solid on Django. I'm really starting to pick up speed. I get most error messages and can find things quickly.
What editor/IDE do you use?

[lime frigate]

I know it's dumb but i use python's built in one😂

[ionic raft]

I don't know it's dumb 😄
If it works, it works!

[lime frigate]

For javascript i use notepad++

I don't really care about ide tbh kinda lazy

[ionic raft]

I've not used it. I got started with PyCharm from day 1.
Yes, I get simple.

[lime frigate]

I even code on phone, termux

[pliant shoal]

wow

vs code and nano is good tho

[lime frigate]

Like when i'm outside or the computer is not available i just use termux

Works great also

[ionic raft]

PyCharm does teach me good PEP....and catches errors before I was time. But, the biggest gift of PyCharm is the things it suggests that help do things I coul;dnt before

[ionic raft]

You'll be set then. Can code ANYWHERE...

[lime frigate]

Yeahhh craving for new knowledge anywhere ahahahah

I hope as soon as i finish my education i can get a job asap

[ionic raft]

Need app? Give me rock and chisel! Can code you app!!!

[lime frigate]

But tbh i really hope the things i'm learning atm can gimme some sort of head start to conpete with others

Like getting a high salary job

[ionic raft]

If you get how to solve problems and translate that into value...you'll get a job

[lime frigate]

But nowadays a lot of ppl know programming so the competition is quite tough

[pliant shoal]

yeah most of them

[ionic raft]

Sure. Lots of people can program. But knowing how to solve problems and deliver value...that's the opening.

If you build a portfolio of projects that show you can solve problems and create valuable applications...it'll create the opening

[thorny quartz]

@ionic raft can you suggest me any site so that i can learn and understand Django

[ionic raft]

Sure. My initial teacher was Corey Schafer on YouTube...AMAZING start.
https://www.youtube.com/watch?v=UmljXZIypDc&list=PL-osiE80TeTtoQCKZ03TU5fNfx2UY6U4p

hello everyone I have a project to integrate react frontend with plus S and I am clueless about how to do the integration I have searched on the internet about the integration and this I got the result of using Axios API My target is to get input from react form standard data to the flask backend and redirect the user from that form to another form how can I achieved please tell me the steps and can you please guide me through the code.

[dusk portal]

how can i add a recurrsive (if) method so user can only delete his posts not anyone's else

class Post(models.Model):
    title=models.CharField(max_length=100)
    url=models.URLField()
    author=models.ForeignKey(User,on_delete=models.CASCADE)
    published_on=models.DateTimeField(auto_now_add=True)

@api_view(['GET','DELETE','UPDATE'])
@permission_classes([permissions.IsAuthenticatedOrReadOnly])
def detailview(request,post_id):
    if request.method=='GET':
        try:
            tasks=Post.objects.get(id=post_id)
            serializer= PostSerializer(tasks, many=False)
        except Post.DoesNotExist:
            raise Http404('OBJ NOT FOUND')
        
    if request.method=='DELETE' and User.objects.filter(username=request.user).exists():
        task_del=Post.objects.get(id=post_id).delete()
        return HttpResponseRedirect('/')
    return Response(serializer.data)```

rn any logged in user can del posts

[dusk portal]

@api_view(['GET','DELETE','UPDATE'])
@permission_classes([permissions.IsAuthenticatedOrReadOnly])
def detailview(request,post_id):
    if request.method=='GET':
        try:
            tasks=Post.objects.get(id=post_id)
            serializer= PostSerializer(tasks, many=False)
        except Post.DoesNotExist:
            raise Http404('OBJ NOT FOUND')
        
    if request.method=='DELETE' and Post.objects.filter(author=request.user):
        task_del=Post.objects.get(id=post_id).delete()
        return HttpResponseRedirect('/')
    return Response(serializer.data)``` now done this but getting error and when i  comment (last 4th line  from the end ) it works fine

else error

UnboundLocalError at /24/
local variable 'serializer' referenced before assignment```

[eternal blade]

Put the return inside the try block

[dusk portal]

Which the HttpResponse one or the last one @eternal blade

[eternal blade]

In the first if statement

[long jackal]

The code is too big for this so I asked it in stackoverflow, if anyone can help here's the link:
https://stackoverflow.com/questions/68789732/how-to-detect-collisions-in-js-canvas

[dusk portal]

Btw is my approach /logic correct (see the last 4th if statement) to get to know which user is logged in and who is the author see the models too

[dusk portal]

@eternal blade

[eternal blade]

if an anonymous user makes an request to the api the code will break

[dusk portal]

Yes

[eternal blade]

Add another if statement inside the second one

[dusk portal]

Author = the one who made the object (author)
So author=request.user

I'm coding from 2.5 month in django

Most of the problems are in

If else and those

Indents

😂😂

[native tide]

Can someone help me with dependent dropdowns in flask?

I am trying to do that

[dusk portal]

i have a blog app and i want user can see all the posts there in home and psgination view too but he can only delete the posts by him as author is connected to ForeignKey so it;s sending to User db too and the db too

@api_view(['GET','DELETE'])
@permission_classes([permissions.IsAuthenticatedOrReadOnly])
def detailview(request,post_id):
    if request.method=='GET':
        try:
            tasks=Post.objects.get(id=post_id)
            serializer= PostSerializer(tasks, many=False)
            return Response(serializer.data)
        except Post.DoesNotExist:
            raise Http404('OBJ NOT FOUND')
        
    if request.method=='DELETE' and Post.objects.filter(author=request.user):
        task_del=Post.objects.get(id=post_id).delete()
        return Response(f"{task_del} have been deleted")```

[eternal blade]

in the second if statement remove and Post.objects.filter(author=request.user)

add that logic in another if statement inside the second one

[dusk portal]

umm

ohk

[eternal blade]

What attribute is the posts author?

[dusk portal]

    if request.method=='DELETE':
        if Post.objects.filter(author=request.user):
            task_del=Post.objects.get(id=post_id).delete()
        return Response(f"{task_del} have been deleted")```

[dusk portal]

class Post(models.Model):
    title=models.CharField(max_length=100)
    url=models.URLField()
    author=models.ForeignKey(User,on_delete=models.CASCADE)
    published_on=models.DateTimeField(auto_now_add=True)

umm

[eternal blade]

if request.method=='DELETE':
    post=Post.objects.get(id=post_id)
    if post.author == request.user:
        post.delete()
        return Response("Success!")
    else:
        # Return Status 403 Forbidden

[dusk portal]

wow

u r hero

[eternal blade]

😄

[dusk portal]

umm

if post.user == request.user:
@eternal blade i have used this cez this make more sense

[eternal blade]

Doesnt look like the Post model has a user field

[dusk portal]

post.user i mean

lol

if request.method=='DELETE':
post=Post.objects.get(id=post_id)
if post.author == request.user:

@eternal blade

[eternal blade]

Yeah, that looks right

[dusk portal]

ohk

how u learned btw u r coding in django and drf from @eternal blade

it's my 2 n a half month ig im not that good

and i only focused on it

im good but not that

at making own logic i'm not that good rn at this point

im 16 my mind is not that much developed( nice excuse by me)

[eternal blade]

I watched a tutorial on youtube to learn django and I made some projects to learn drf

Still working on the drf project

Haven't made the frontend yet...

The frontend is the hard part

[pliant shoal]

Hi

[dusk portal]

u learning from how many months @eternal blade

[eternal blade]

I've been learning drf for about 2 months and django for about 9 months

[snow sierra]

HEY!

i have

updated = models.DateTimeField(auto_now=True)

template:

{{ post.update }}

it gives me [Aug. 15, 2021, 5:27 p.m.]

how can i filter?? Maybe only [Aug 15, 2021]

[inland oak]

Interesting.

Using something like this https://pypi.org/project/jsonpath-ng/

could be useful in order for API to be more versatile to incoming JSON input

which leads to less couping, which leads to less rippling effects.

[past cipher]

is it possible to embed a file directly into html

like a pdf document

[inland oak]

is it embedded enough for you?

[past cipher]

@inland oak I tried iframe to embed an image and it worked, and then I tried with one of my files, and it didn't work. I soon realised that even when i visit the URL in my browser, it auto downloads - hence why I couldn't embed. Thanks for the link, because it made me realise my mistake

[hardy nebula]

Someone knows how to get API of a website?

If yes please help

[ionic raft]

You can search (DuckDuckGo/Google) API along with the name of the website and if they have an API available it'll come up in the results. You also check out if they have documentation.

[inland oak]

https://www.programmableweb.com/apis/directory
there is even public and free database of available APIs

quite full one in my opinion

anyway, if there is no information about existing API

you could always try emailing the tech support of the web site

[snow sierra]

oo yes
value|date:"M t, Y" it works 🙂

and auto time showing wrong Month.. in settings everything is ok.. cannot find reason.. do u know something?

[ionic raft]

Date formatting is very useful.
I've not seen auto time show the wrong month.
I would double-check the formatting... Aug 15, 2021 would be "M j, Y"

[snow sierra]

OMG!!! am i drunk?? 😄
t Number of days in the given month. 28 to 31

How all r getting pycharm professional I don't have id which I have given to school

[ionic raft]

I pay for PyCharm professional. Working with a DB in Django makes the pro version very helpful and worthwhile. I know you can use other services for viewing a SQL DB, but having it all in the IDE works for me.

Wow

I only ask my parents to pay for Udemy couses

😂😂

And sometimes book

Asking them to pay for your IDE is a valid ask. Say it's for learning, and it will help you.

That's very cool of them.

[dusk portal]

Sure

[ionic raft]

I have a saying...
The opinions of others are none of my business.

[dusk portal]

Dsa = a good job and Google n FAANG companies
Development = This is taught when u join a company

Ppl say this

You can't make any commercial application though...

[dusk portal]

Got it

[hardy nebula]

Actually I wanted API of this👇
https://points.fwa.farm/

But still I'm unable to get it's API

[ionic raft]

Not every website has an API. If their terms of service don't prohibit it, there's web scraping as a choice. I believe if you enter robot.html (typically) you'll get to see what scraping is not allowed.

[hardy nebula]

Ok I understand that 👍
Is there any other way🥺

[native tide]

#help-lemon

[ionic raft]

Not that I know of. If there's no API then web scraping is what you're left with. I've used BeautifulSoup and Selenium. Selenium is more robust and I found it to be very interesting to use.

Selenium comes with ChromeDriver, which will allow you to set up browser event automation. Which is useful.

Hello guys, I'm brand new to Django. I followed a really stupid tutorial on Yt and I'm stuck.
Basically, my model class looks like this:

from django.db import models
from django.contrib.auth.models import User

# Create your models here.

class ToDoList(models.Model):
    user = models.ForeignKey(User, on_delete=models.CASCADE, related_name="todolist", null=True)
    name = models.CharField(max_length=200)

    def __str__(self):
        return self.name

class Item(models.Model):
    todolist = models.ForeignKey(ToDoList, on_delete=models.CASCADE)
    text = models.CharField(max_length=300)
    complete = models.BooleanField()

    def __str__(self):
        return self.text

Without the user variable everything works but I wanted every user to get a different page with different todolist items. When I do absolutely anything I get this error: table main_todolist has no column named user_id

[ionic raft]

As for great Django tutorials, Corey Schafer is AMAZING.

[fossil pond]

Thanks, subbed to him right away!

[ionic raft]

Wait a minute...why do you have an Item as a child to ToDoList?

[fossil pond]

Nah item has todolist as a foreign key so todolist is made up of one or more items

[ionic raft]

So, you can have multiple todolists?
That's going to get challenging quickly. To render both those forms together in a formset you'll need an Inline Formset. Those are AMAZING by the way...I've built two...but they're far from beginner Django

I must be missing something...a Parent-Child relationship for a todo list seems over-engineered to me. But then, I don't know the extent of the use-case.
And there are better teaching examples IMHO that could be picked to demonstrate a Parent-Child build.

Just joined...perfect timing

[fossil pond]

Oh yeah that video was horrible the guy made tons of mistakes. I've worked with Ruby in the past so I could see many obvious ones.

I swear on youtube the dumbest programmers get the most views

[ionic raft]

Ouch...
Well, you'll enjoy Corey. HIs stuff is solid.

[ionic raft]

Being skilled in something ! automatically = good teacher.

And if skill is lacking...that's brutal

[fossil pond]

To answer this, yes. Each user will have multiple todolists. It was all working, until I tried to make it user specific and basically put that user variable. None of my functions worked after that.

[ionic raft]

Question. How will users tell their todo lists apart? Do they have a different focus?

[fossil pond]

After logging in each user would only see their own todolist

Logging in is compulsory

[ionic raft]

Uhhh...
But you still don't need parent-child for that...
Just filter by the user and have a single todo list?

And logging in is compulsory for the approach I took.
But then, I'm new. My questions aren't challenging the approach. I'm trying to understand how two tables are better/more efficient in this use-case?

[fossil pond]

No idea how to do any of that

[ionic raft]

Ooohhh...
Simple...Queryset in the view.
Filter for the user....gimme a moment...

[fossil pond]

I just wanted a working tutorial/small project from where I can learn on my own

[ionic raft]

You'll need to learn about querying... 🙂

[fossil pond]

That video i clicked was a nightmare

[ionic raft]

My recommendation...watch Corey for a bit...he'll set you straight 😄

[fossil pond]

His video of Django is 3 years old, would that be alright?

[ionic raft]

by the way, the query for ToDoList would look something like...

ToDoList.objects.filter(user=self.request.user)```

[ionic raft]

Yeah. I watched it 1.5 months ago. My site is solid

The above filter takes care of building a query of tasks. You can either assign that filter to a variable or context dictionary (Class based view). But that'll be explained when you get into views...

Trust me when I say, learning how to dance with the Django DB is some of the most fun you can do with a website. It took me a bit, but bruh...ORM in Django is da BOMB

This is the home/dashboard of the web application I'm building. And it all started with Corey and that series on Django...

How do I revert this to use in a class component```jsx
const BaseJoi = require('joi')
const ImageExtension = require('joi-image-extension')

const schema = Joi
.image()
.minDimensions(100, 50)

[fossil pond]

Looks epic, btw I got mine to work. Just migration issues, I deleted the cache files and the database files and migrated everything again

How do I validate images with Joi browser?

export default class CreatePost extends Form {
  componentDidMount() {
    this.props.toggleShowSearchBar(false);
    axiosInstance.get().then((res) => {
      const slugs = res.data.map((post) => post.slug);
      this.setState({ slugs: slugs });
    });

    const BaseJoi = require("joi-browser");
    const ImageExtension = require("joi-image-extension");

    const Joi = BaseJoi.extend(ImageExtension);
  }

  state = {
    data: { title: "", image: "", content: "" },
    errors: {},
    slugs: [],
  };

  schema = {
    title: Joi.string().required().min(10).max(80).label("Title"),
    title: Joi.string().required().label("Image"),
    content: Joi.string().required().min(100).label("Content"),
  };

I have this at the moment

I want to access Joi from componentDidMount

or can I store it in the state?

[thorn igloo]

you can define it in it's own file and import it wherever you want to use it

[native tide]

good Idea

[native tide]

I did this ```js
const BaseJoi = require("joi-browser");
const ImageExtension = require("joi-image-extension");

const Joi = BaseJoi.extend(ImageExtension);

export default Joi;

In here jsx schema = { title: Joi.string().required().min(10).max(80).label("Title"), image: Joi.image().label("Image"), content: Joi.string().required().min(100).label("Content"), };

I get this error now

RangeError: Trying to access beyond buffer length

[thorn igloo]

i don't use joi so i don't know what that even means

[native tide]

joi-browser gives that error

ok

is there any way to restart my flask server within flask? trying to make an "update" command for my flask admin panel

[ionic raft]

Check your views, both the POST and GET branches (if I'm reading that right).

[ionic raft]

I'm not aware of a way of doing that. I've only seen restarts done in the terminal or through the IDE (which is running commands behind the scenes into the terminal space)

[timid nest]

I'm aware an IDE is just running python app.py my question was more of is there a built in method to restarting the flask loop, guess not.

[thorn igloo]

you're giving it two arguments when it only needs 1

they have somewhere mistake in their educational system, which affects all indians %

I wonder if it could be possible to email all educational indian organizations to fix it.

[vestal hound]

I wouldn’t really call it a mistake

just a regional thing

for example, in my country we say “stay” when we mean “live”, and Americans spell “brooch” “broach”

[inland oak]

like dialect?

something like that! that’s more or less how they form

So recently, I tried to use selenium to load a website in a browser, navigate to a button and click it, then closing the driver and starting over again (To clear cache)
I got it to click about once every 5 seconds per active script i had open, most of the time going into actually restarting the browser driver and loading the webpage

Later though, I found out somebody else was clicking the same button roughly 5 times per second, which I could simply not achieve.
Is there a way to load and click the buttons with Python, without rendering or reloading the website / driver?

That's my code by the way, the reason for the try and excepts is because of a cookie message loading at different times, and i need to call the button press on the actual button twice because it cant click on it the first time since its not clickable at that moment

hey guys! I have a Volunteer model that has a OneToOne field with a User. How could I update some User fields when updating Volunteer fields? in DJANGO

[thorny quartz]

can someone tell me meaning of this line {'movie': movie}) in this code

def view(request, id):
movie = Movie.objects.get(id=id)
return render(request, 'view.html', {'movie': movie})

[thorn igloo]

it's a dictionary

[versed python]

Show some code. What's not working?

[dense slate]

'movie' is the word you will refer to in your templates. and the second movie is the variable in your function that 'movie' is referring to.

the whole thing in the {}'s is the context that is being returned to your template

you can also do something like context = {"movie": movie, "2ndVar":2ndVar, "3rdVar":3rdVar, etc}

and just return context

[native tide]

I don't know if its a dumb question or not. but lets say I have an async function In javascript
Is there a way to have it start running in the background on a certain event, and then await the result on a button click?
sort of to make it have a head start and make the result appear faster

so lets say I have a form with a txt input and a button. I was thinking of when a change event happens on the txt input, it starts the async function (to have it run in background) and when the button is clicked we await the result of the async function

or is there another way to think of this / do it in a different way. I'm not very knowledgeable on asynchronous stuff

If I am not making sense, tell me to clarify 😄

Hi, can anyone help me change the primary bootstrap color on a flask webapp? I want the default primary link/button color to be custom.

[thorn igloo]

just add a custom style sheet

[ionic raft]

I'm still learning myself, so I there may be additional clarification from others. As @thorn igloo mentioned, you need to add a custom style sheet. When you load in Bootstrap you add the stylesheet links to the header if you're using Bootstrap through the CDN. When you add a main.css (or other name that works for you) in your project's static folder, you then can overwrite all the styles you want. What happens (if I recall correctly) is that Bootstrap's defaults are applied (because you called the Bootstrap style in the header) and then your custom stylesheet is applied.

This is accomplished by loading Bootstraps stylesheet link and then your stylesheet link into your template header. Here's a snippet of this in my Django project's base.html template. html <!-- Bootstrap CSS --> <link href="https://cdn.jsdelivr.net/npm/bootstrap@5.0.2/dist/css/bootstrap.min.css" rel="stylesheet" integrity="sha384-EVSTQN3/azprG1Anm3QDgpJLIm9Nao0Yz1ztcQTwFspd3yD65VohhpuuCOmLASjC" crossorigin="anonymous"> <!-- Local CSS --> <link rel="stylesheet" type="text/css" href="{% static 'articles/main.css' %}">

I make extensive use of commenting across all files and languages. If you're using Flask the syntax will be a little different for the href to the location for the custom css file.

I am making a game platform website, with a list of games. I have coded the games but want a dynamic way to list them. Similar to how youtube lists it's videos
This is how the games are stored

games = [
  ["name",
  "description",
  "author",
  "file location"
  ],
]

So what I am looking for is a way to create a element from JS, have it look nice (so either a way to create a template in html, then reuse in JS for each game. Or create the template in JS and reuse for each game). Any help on how I can do this will be appreciated

[ionic raft]

This is a great question. I'm working on a large web application and know refactoring is definitely to be done. At the same time, things are working great too.

One of the challenges with refactoring is that there are some very valid reasons for conditions. My web app has 5 subscription tiers, along with two other fields against a profile that determine what each user should see. In addition, there are some 19 tables in the DB, and a number of those tables require queries to determine counts of the records that belong to the user that they can then access/have count totals rendered in the template. The web app is a complex process improvement project management application with lots of tools per project available.

There is no cookie-cutter approach for refactoring here. Certainly, the extent of refactoring required will be determined by the design approach to coding I took in the first place. If I made good use of functions, then I should have no instance of repeat code in the file. I should be able to call functions when those queries are needed repeatedly.

However, and this is my newness speaking (only coding Python for 4 months) I am wondering if I could make use of calling functions from other files to save on making those functions within each file. The result I am envisioning is that I only have a function written in one file, and then make that function available through an import within every other file, and then invoke it.

I look forward to insights shared on this question.

[ionic raft]

TL;DR: I try to build web apps by using the back-end web server to create the structure, style and data for a web-page and use JS for managing web page behaviour that responds to how the user interacts with the web page.

A few questions. What web framework are you using? Flask/Django/Other?
How are you storing the game data? In a DB? Games appears to be a list of lists based in your snippet. Might there be an improved data structure for your games? I could see a list of a dictionary being something that can be queried.
Your question about creating an element from JS...I use the application layer in Django to query the DB, and then prepare the data for the template render, which is then built in html. This may be my newness speaking, but my general design philosophy is to have the web server build pages where possible, and leave JS to focus on front-end behaviour. If I start by offloading the build of the front-end in the front by relying primarily on JS I'm putting the processing demand on the client web browser. My understanding is that that is not as efficient.

Look up the basics of CSS selectors. .header is targeting any element with the class header, not the header element which I think is what you're trying to go for. Same with h2.

If I'm not mistaken, you can just remove the period before header and h2 in your style

the period will look for a class with that name

Hi folks, relatively new with using flask. I have made an API that uses the flask framework and gunicorn server. I serve POST requests via it. What I want to do now is, add authentication on flask level. Basically I would have 3 parameters that should be passed via headers i.e. Team, API Key, API Secret. I'm not finding a clear guide on this, can anyone help?

[honest dock]

nevermind

lol

[true kernel]

lol yea

my page is taking too much time to load as its pulling data from an api

is this the time to use redis?

I might be wrong, but I think redis is used for distributed cache, and this seems like a temporal cache problem to me

[quick cargo]

better to test rather than make assumptions

e.g. have you used the network tool on your browser to get more detailed info on whats taking the time load

have you timed the latency of the server code itself

[true kernel]

fetching data from the api

i tested it on jupyter, and its consistent

takes around 5-7 secs to load

[quick cargo]

well, is it your api? is it someone elses api? How do other browser behave? Where is the api server located? where are you located?

[true kernel]

how do these things matter though

[quick cargo]

How much data are you request etc...

yes

they all matter

[true kernel]

sure, when i make a fancy program

but not really when its just a mini project, right?

[quick cargo]

• If its not your api you cant do anything about it
• If its one browser loads really fast and another doesnt, is something broken on the client side
• If the api server is on the otherside of the world to you there is naturally going to be more latency, normally from UK -> US is 100ms+ of additional latency for a simple message, now consider how much more latency that adds when it's a large payload chunking data.

[true kernel]

sure, but in the end its taking time

so i would want to load it beforehand

[quick cargo]

well this is how you debug that :P

you also want to consider what the data actually is

how big is data should be your first question

/ how much data is there

if you're trying to load GB of data its obviously going to take a while

[true kernel]

im not sure this matters

i mean, I get your point

[quick cargo]

All of this very much matter, redis isnt a silver bullet and isnt going to magically make it faster at all

[true kernel]

these are important things, but not for this specific thing

[flat temple]

Anyone know how to add Mocha.js or Jest.Js to a Django application?

[quick cargo]

well you have yet to give any more specific details so im just listing off the standard debugging proceedure

[true kernel]

sure so im just pulling stock data from nse(national stock exchange)

[quick cargo]

okay, and how long does that api take to respond on average

and how much data does it return

[opaque vale]

laying out html and css is infuriating and i think im gonna take a sledgehammer to this

[true kernel]

so for the most part its the same data on the home page, and i would not want it to pull it everytime im reloading the homepage

[quick cargo]

are you using any css framework?

[true kernel]

depends on the query. 5-7 secs for this problem

[opaque vale]

I'm using django/bootstrap and I just want a container with a header in the middle and two divs left/right below it as a split view

and for some reason this shit is the most difficult

[quick cargo]

would say try out tailwindcss very nice framework to use

[opaque vale]

Trying another framework isnt gonna make my issues go away though its just going to make them worse shortterm so i'll pass thanks

[true kernel]

maybe you should just properly learn html/css/bootstrap. Might take you a whole day but itll be worth it

[quick cargo]

to do that it would be

<div class="flex flex-col items-center">
  <h1>Hey, Im centered</h1>
  <div class="flex justify-between">
    <div>Im a container</div>
    <div>Im also container</div>
  </div>
</div>``` in tailwind

[true kernel]

you can refer to traversymedia on youtube. Or w3 if text is your thing

[quick cargo]

but TLDR flex boxes are your friend

[true kernel]

word. cant believe i discovered them only yesterday

[opaque vale]

I'll take a look thanks

from django import forms
from django.contrib.auth.models import User
from .models import UserProfileInfo


class UserForm(forms.ModelForm):
    Password = forms.CharField(widget=forms.PasswordInput())

    class Meta():
        model = User
        fields = ('username', 'email', 'Password')


class UserProfileInfoForms(forms.ModelForm):
    class Meta():
        model = UserProfileInfo
        fields = ('portfolio_site', 'profile_pic')

<form method="POST" enctype="multipart/form-data">
    {% csrf_token %} {{ user_form.as_p }} {{ profile_form.as_p }}
    <input type="submit" value="Register" />
  </form>

so i am following this tutorial and the mentor uses
user_form.as_p
and
profile_form.as_p
and i didn't quite get what user and profile in form.as_p means?
there is no variable named profile in my code, only have profile_pic

[ionic raft]

I would add to the recommendation for Corey Schafer. I took his Django series. 20,000 lines of code and 1.5 month later and I look back and count that start with him as an excellent foundation. He also has a great Flask bootcamp.

[ionic raft]

I started a few months ago and was pointed in the direction of Bootstrap as a css styling framework. I cannot emphasize what an excellent starting point Bootstrap 5 is! Even though my web application has grown to huge proportions there's not been a moment where I've felt the need to ditch it. This is the end result of the logged-in dashboard for a process improvement project management web app...

[ionic raft]

I believe that form.as_p is a standard tag that will render the form fields with paragraph breaks. There are other ways of presenting a form. It's a quick way of separating all fields with paragraph breaks. If you don't use a formatting tag the form will be messy as each label and field will be displayed in order with no layout structure whatsoever.

If you really want to maintain simple (where you don't build your form manually, inputs/labels/text etc.) then you can look at crispy forms. Combined with Bootstrap, and Crispy Forms will instantly make very pretty forms with very little effort.

[nova pewter]

i get the form.as_p but why did he use "profile_" before it? to my little knowledge that doesn't reference to anything.

[ionic raft]

Because there are two forms being presented in the template: form (for the user signin) and profile (for the additional profile info). Even though you're not showing your models.py file, I can see that you are showing forms.py. I observe two forms, UserForms and UserProfileInfoForms.

Also, without seeing views.py for the app I cannot verify if the template will render as expected as I am unable to see if the forms are passed into the template correctly.

Whew...I started Django 1.5 months ago from new. I'm starting to really get it 🙂

[nova pewter]

so its just like commenting and has no effect on the form?

[ionic raft]

Not really. If you need help troubleshooting a framework like Django you need to understand the sequence:

• models.py for the app ishows what the DB stores, the data structure.
• forms.py is where you (optionally) build a form explicitly
• views.py is where you build the View. You can specify fields here and thus have no need for forms.py
• your html file (the template) will need the tags to render the variables that views passes to it.
• finally, urls.py for the app will need the url pattern to ensure you can refer to it through a static url link.

The challenge here is you showed only 2/4 snippets needed to verify/troubleshoot. You showed forms.py and the template. But without models.py and views.py for the app we can't really troubleshoot.

the tag .as_p is a quick and dirty way of taking the form fields passed from the view (potentially declared in forms.py, but not always) and rendering that form. Rather than seeing it as "commenting" look at as_p as formatting.

[nova pewter]

i see, thank for the help i'll look into it.

[ionic raft]

You're welcome. The Django documentation on forms is excellent and is well worth the read. It'll explain both the quick way {{form}} and building the form field by field. However, I've not needed to build a form manually as yet.

[nova pewter]

as you suggested i have bookmarked crispy forms i will look into it later on, any other libraries worth checking out?

[ionic raft]

🙂 Crispy forms is excellent. This is a screenshot of it working on an Inline Formset (about as intense as Django forms gets - a form with both Parent and Child rendered). This was literally rendered with {{ failure_form|crispy }} for the bulk.

[nova pewter]

cool

[ionic raft]

Yes...not having to manually build up a form is very cool. It also guarantees a consistent input UX across your site. My sense is that crispy forms combined with Bootstrap will provide for most input capture needs. Anything more demanding, such as splitting fields across rows etc. would need to be manually built.

[nova pewter]

thanks for the help fam!

[inland oak]

perhaps you have messed up static file server hosting

by any chance you are using whitenoise?

if yes, that's the problem.

[twilit needle]

bootstrap is very opinionated. Use tailwindCSS instead to build the same things easily, but with more flexibility. tailwindCSS isn't an alternative to bootstrap. It's something newer and different

https://tailwindcss.com/
docs are here

[proper hinge]

Sometimes I feel like in the only person who likes CSS

Don't get me wrong, the classes in these frameworks are convenient, but when I'm combing a bunch of tiny building blocks it just creates a mess of HTML

My understanding is that the goal of tailwind is to take that idea to the next level. I was already finding the HTML getting messy when using bootstrap.

[ionic raft]

Offering an un-requested opinion about tearing bootstrap out my web app project (some 20k lines big already) to replace it with Tailwinds with zero context for my project, the roadmap, or the timing of release, is not actually helpful...at all. I appreciate the intention. As for relevance or practical advice, it leaves a lot to be desired. I suggest checking in for some validation before weighing in with such an un-invited opinion. IF my website looked like dog shit that'd be one thing. I happen to think it looks decent for a v1 prototype built in 6 weeks by a web dev who didn't know Python before Apr 15, 2021, and learned css only a couple of months ago...

[versed python]

i think you are

css is a pain ngl

[ionic raft]

I like CSS. However, as someone new to CSS, what Bootstrap gave me was a decent looking foundation to build on for this v1 web app. Function AND form matter. I didn't want to spend months learning about form and style without function in play.
However, now that I've used bootstrap I've learned a LOT about css. I'd actually see going without a Framework as a great learning experience down the road.

[versed python]

yes using bootstrap for the first few projects is absolutely the way to go imo. theres not much to learn and yields decently good websites.

Css without any framework quickly turns into a nightmare though with separation concerns, naming and unused css.

[ionic raft]

I've received some very good feedback on my first web application's UX and style. 🙂

I'm about to launch 3 months of open alpha testing. That'll show me the way 😉

[proper hinge]

The idea of "never leaving html" is ironically a really bad advertisement for me. I think with larger projects it would be nicer to build custom css classes that use a preprocessor combine stuff from a css framework.

[versed python]

yes i looked at it a few days back it looked good

[ionic raft]

I actually just completed building the alpha testing application forms today. About an hour ago.

[versed python]

to each their own i say

i personally dont like switching to some other file just to see what btn applies

[ionic raft]

Ironically, for most UX function I moved away from buttons. There are two on the navbar, some for some forms. But for tabular display (process improvement project management app after all) I went with + and x for update and delete...

[versed python]

im sure you used other classes in that text. whats used there?

[proper hinge]

I find html with a bunch of classes in each element to have poor readability. Furthermore, the purpose of using some class can sometimes feel unclear as it just appears like random classes combined together since the building blocks are so small.

[ionic raft]

My UX challenge is a balance of Form AND Function. When you're building a rich information active working site, space is at a premium

[violet lynx]

tks @inland oak but no static file here, it runs fast on my local server but slow on digitial ocean server, fixed /etc/hosts but no effect

[ionic raft]

Oh my goodness...I'd have to check the template to answer that...
The thing is, I've actually layered custom css on top of Bootstrap. The last I checked there were 649 lines of css...
08-15:
320 files
11,118 Python
7,601 html
649 css
19,368 total

Which was my point. Bootstrap gave me a foundation I learned to navigate and make my own. It saved me a ton of time and got me to a decent style without holding me back.

[versed python]

I'd say this is quite readable

[inland oak]

which web server you are using btw?

gunicorn?

[ionic raft]

I find that naming a css class with an understandable name is as relevant for readability as naming a function, variable or class in Python.

[proper hinge]

I was ending up with stuff like class="row row-cols-2 row-cols-xs-3 row-cols-sm-4 row-cols-lg-6 justify-content-start g-3 mb-4"

Not very nice

[versed python]

that looks like bootstrap tho

but yes

[proper hinge]

Yes it is

[versed python]

Look into https://windicss.org/

[ionic raft]

LOL'ing here....
And yes, it does look like bootstrap. AND, when you learn bootstrap it actually becomes readable.

I'm not supporting it for readability, just saying that with time it can be read.

[versed python]

Especially this https://windicss.org/posts/v30.html#attributify-mode

[manic frost]

@proper hinge I like how in the "Build whatever you want, seriously" section (https://tailwindcss.com/) they demonstrate how you have to modify the entire HTML of a thing to change how it looks, and you can't change it at runtime (e.g. with CSS variables), or by just changing a stylesheet definition

[ionic raft]

By you like how...you mean, not like much?

[proper hinge]

Attributes look nicer, but still, I prefer the CSS syntax for representing style over defining it in html. It's just not as readable as CSS to me.

[versed python]

as i said

to each their own

[manic frost]

yeah I guess it's more of a preference

[ionic raft]

My intention/plan down the road is to hire someone who LOVES css and have them improve LanesFlow. I don't need to be the css-guru. It's not my bag, nor does it need to be. I'm just glad I could get v1 to a state where style > dog shit 😉

[twilit needle]

this might be out of nowhere, but if you try it you'll know the difference (I was also using boostrap prior). However, feel free to ignore my opinion

[proper hinge]

Yeah thanks for the recommendation though. I might try it next time I work in a site to get a feel for it

I also never put to practice the idea of using a preproccessor to combine framework classes into my own class

[ionic raft]

Like I said, your opinion didn't read like an opinion. In replying to a screenshot of my web app, you basically said, Bootstrap is very opinionated, tear it out and replace with this...without any context of how absolutely impractical that opinion is to apply.

[violet lynx]

wsgi

[twilit needle]

I didn't literally tell you to tear it out..

anyways it doesn't matter

[inland oak]

a bit more detailed.

what is your docker running command there?

[ionic raft]

When I read "Use tailwindCSS instead to build the same things easily, but with more flexibility" in reply to the screenshot that is how it came across. You started by saying that Bootstrap is opinionated, and then proceeded to offer your un-invited opinion about how I should be using something else. Had you simply offered that opinion without quoting me on the screenshot of my web app it would have been a non-issue

[native tide]

Is there a chance to create random planets and put details and its other features on web and use it for discord bots

[violet lynx]

python manage.py runserver 0.0.0.0:8000

it's working well on one machine

[twilit needle]

is anyone into python graphql here?

[violet lynx]

this's very strange to me

[inland oak]

it is development only server.

[versed python]

yeah

[inland oak]

you should not use it when deploying to anywhere else, it is only for your localhost.

[inland oak]

read https://docs.djangoproject.com/en/3.2/howto/deployment/

[twilit needle]

have you been successful with it? I feel that the ecosystem needs more features, like validation rules, input validation and a lot more

[versed python]

absolutely lol

i wrote a para a few days back mourning this

here

oh wait

that was a reply to you

lmao

[twilit needle]

also, python is a single threaded language. So, you don't get "real" multithreading, and will be writing blocking code. The only way to use dataloaders with frameworks like django and flask is through the "promise" library, because they shouldn't block. If you use asyncio supported libraries like quart, you can use quart instead. But promises aren't native in python and I dont like it.

This is what github did with ruby (another single threaded language). They promisifed blocking code

[native tide]

I want to create an planet rp bot

[twilit needle]

I started to doubt if single threaded languages should be used with graphQL

when you do it in javascript, everything fits nicely

[manic frost]

isn't Future the same as a promise? what's the difference?

[violet lynx]

you means the 0.0.0.0, it's inside docker, anw tks for that point, my current isssue is it's very slow, just return HttpResponse(0) took 2s

[proper hinge]

Yeah it's the same concept

[versed python]

have you tried Rust? How does it play with graphql?

[twilit needle]

no clue there lol

but I know they have a library named Juniper

[inland oak]

I use CMD gunicorn core.wsgi -b 0.0.0.0:8000 at the end of my dockerfile

plus serving static files and attaching certificate with nginx as reverse proxy (which is made as second docker container running together with first one via docker compose)

[versed python]

can you send me the config of the second container? I was not able to do it a few months back. Do you have a repo I could see?

[twilit needle]

but for python, asyncio should fix all the problems. The only problem is that the major players in this ecosystem, django and flask, weren't really built for asyncio. You'll have to use FastAPI or Quart or Sanic, but they are very new libraries and it feels like moving away from the gold standard

[violet lynx]

let me try with gunicorn, I'll report later

[proper hinge]

I think there are async decent substitutes for flask, but not for something as substantial as django

[versed python]

yes not having django just breaks my heart

but the community there is very stagnant

[twilit needle]

django doesnt support asyncio yet because it's ORM is sync. But because they have a lot of batteries included, they can't do a lot of breaking changes easily.

so we cant expect it in the foreseeable future

[elder rover]

hi.. any idea build booking time slot like this, how to print date like this

[twilit needle]

also, a lot of python ORMs are sync

[proper hinge]

[elder rover]

how to select the date when the user selects. what I need to learn. sorry i just started

[proper hinge]

You could use JavaScript to register a click event handler on the dates.

[versed python]

ahh lgtm. thanks!

[deft shore]

Is there a better or cheaper alternative to S3 Buckets? Specifically for a Django project.

[versed python]

why do have port 5555:4000 mapped?

[inland oak]

inside container it has 4000, i needed the service exposed at 5555 port to outside world.

in your case you could exposing to 443 port

plus, you would need a bit editing nginx config

so it would redirect from 80 port to 443 port, and exposing nginx 80 port then

[versed python]

alright thanks

have you used dokku?

heard a lot about it

[inland oak]

nope

first time hearing

[versed python]

it manages docker and nginx configuration

pretty slick

plan on using it soon

[inland oak]

how much manages, you mean it automatically installs docker-engine to your server + nginx
and allows you having simplied deploy with one dockerfile?

[versed python]

no it works completely through containers

its basically heroku but for your own server

How hard would it be to set up an e-commerce with just PayPal checkout for 2-4 products using flask?

[thorn igloo]

how hard something is is kinda relative to how much you know

[gentle ingot]

My google-foo is decent.

Django is just overwhelming.

[thorn igloo]

eh

paypal has some documentation on implementing the payment option onto your website. although it looks terrible from what i've seen

[gentle ingot]

I thought about the buy me button. But then if someone wants everything on the site then it would be a headache to group that and not charge separate shipping it seems.

[thorn igloo]

yea buy me button not really that customizable tbh

but that's just me

[worn fjord]

guys can anyone help me with flask?

I'm appending a list to add 2 images in it and then i had made a detec_face function which takes two images as a parameter and returns if they are same or not. But as soon as i run the program on the localhost and send two images it crashes and gives me an error on the detect_face function :/

[thorn igloo]

not enough info to tell what's actually happening

[worn fjord]

`@app.route('/', methods=['GET', 'POST'])

[thorn igloo]

what is the error saying? let's start there

[worn fjord]

ok wait ill run and copy paste directly

[elder rover]

owh.. ok

[worn fjord]

sry its taking some time. just give me a min

@thorn igloo

as soon as i push in the second image

[elder rover]

so I have to learn javascript to learn to do this

[thorn igloo]

what's mtcnn

[worn fjord]

oh its a framework for face detection

comes along with pytorch and opencv. this function was given by another internee to me, i had to integrate flask with this

[gritty coyote]

Hello everyone, Is there a job board in this server?

[worn fjord]

@thorn igloo

[thorn igloo]

if detect_face(list[0], list[1]) i have a feeling your problem is here

[worn fjord]

yes i know but i dont know what really is the problem :/

[thorn igloo]

the function accepts the image paths, you're passing the file object

[worn fjord]

yes but... i changed the detect_face, for example previously it was accepting paths but then in the function you can see i wrote img1= img1path .. previously it was taking the image from the path. now since im just passing the images it should work fine

[worn fjord]

should i save the image somewhere and then pass those paths? because that would be, in my opinion, bad practice, no?

also, i ran the detect face on cmd it's working fine.

[thorn igloo]

the function operate based on a path, you can rewrite it to work on the file directly, else idk

you probably need to save first if you don't want to rewrite the function, unless you can get the path without saving somehow

[thorn igloo]

because you were working with a path,

[worn fjord]

is it possible that it saves somewhere and deletes it afterwards? that's bad but its better than it being saved permanently

[worn fjord]

i think it is ill have to search it up a bit

[thorn igloo]

you can use the os module to delete files

[worn fjord]

yes, got you. well. thank you! 😄

{% for key,value in form.items() %} what is form supposed to be?

you did not pass it in render_template

[dawn shard]

it needs to look like this.

So what should I do next????????

[thorn igloo]

flask.render_template('data.html',form_data = form_data) pass your form as a parameter here

you need to code it yourself

of course, there exist implementations

you can look into, for example, Material Design components

it's still error.

How does Grammerly work?
How do they teach computer to automatically correct the text?
And how can we learn to do that and make something ?

[native tide]

automation

for a start

and then I believe they have a known phrases algorithm that studies other texts based upon well known articles etc and relates it to your texts

[final lake]

is it possible to make that type of softwares

[native tide]

well

yes

thats how it exists today

you just need to learn a bunch of algorithms

[brave stag]

for django what are the feasible web server for apis in production?

[glacial yoke]

why does it give me this error when I try to runserver?:

ImportError: Couldn't import Django. Are you sure it's installed and available on your PYTHONPATH environment variable? Did you forget to activate a virtual environment? 

It used to work perfectly fine, but now for some reason it just stopped working

i tried reinstalling django, but it didn't help

[lavish ferry]

You aren't in some virtual environment?

[glacial yoke]

nope

I never even used virtual environments

I literally have no idea why it would give me this error

[lavish ferry]

Did you try just closing your ide completely and reopening it?

[glacial yoke]

yes

[lavish ferry]

You are definitely importing it correctly? Right capitals/lower-case?

[glacial yoke]

yeah, I have never changed the manage.py file

It is auto compiled when you start your project

I literally haven't looked at it since I started project

[lavish ferry]

Well inadvertently it seems you have changed something

I wish I could help more, though it is probably something dumb/simple

[glacial yoke]

I definitely haven't changed everything

oh well, I guess I'll just have to restart my project

and copy in all the files

it doesn't even highlight as a problem

[lavish ferry]

No idea, any chance you are good at HTML though?

[glacial yoke]

wdym, you need some help?

[lavish ferry]

I need some help

[glacial yoke]

right

yeah, I'm fine with html

what do you need help with

[vestal hound]

@glacial yoke how are you executing it?

[glacial yoke]

in the console?

[vestal hound]

from IDE? in IDE terminal? in external terminal?

@lavish ferry just ask

[glacial yoke]

in IDE terminal

I even tried in external terminal

[vestal hound]

your environment is wrong then

[glacial yoke]

doesn't work

[glacial yoke]

how do I switch it then?

[vestal hound]

see

that’s the problem

it depends on which environment manager you used when you set up the project

[glacial yoke]

idk even know if my environment is wrong

[vestal hound]

the method will vary based on that

[glacial yoke]

I just ran it from my ide, without creating any virtual environments

so Idk why am I getting the problem now

[vestal hound]

it’s defo wrong because Django is showing as not installed

[glacial yoke]

how do I fix it then?

[vestal hound]

there’s a way to check but I don’t remember offhand

in your IDE terminal

if you run pip install django what happens

[vestal hound]

paste as text

[glacial yoke]

Requirement already satisfied: django in c:\users\егор\appdata\local\programs\python\python39\lib\site-packages (3.2.6)

[vestal hound]

run echo $PATH?

[lavish ferry]

Cheers, I keep failing with what should be simple HTML. I just want to have an image container 400px in height and 100% in width, with a 26rem in width card horizontally and vertically centred over the image which contains some H1 text. I can't for the life of me figure it out unfortunately.

[glacial yoke]

$PATH

that's all that it says

[vestal hound]

wtf

what OS

Windows?

[glacial yoke]

windows

yeah

[vestal hound]

ugh

I can’t remember how to do this on Windows

but if Django is showing as installed

then there’s an issue with your PATH

alternatively, PYTHONPATH

these control where Python looks for installed packages

[vestal hound]

the location of your installed packages is likely not contained therein

that’s why they can’t be found

you should be able to Google that

[vestal hound]

100% of the container?

okay so

you want a wrapper

around the image

[glacial yoke]

I tried googling, I can't find the right answer

literally nowhere

[vestal hound]

of the relevant size

[glacial yoke]

Everyone talks about virtual environments, but I have never used one

[vestal hound]

in this you put the image

[glacial yoke]

idk how to even start one lmao

[vestal hound]

and another element

that is absolutely positioned

then use top and left to fix it to the centre

just look into position: absolute

that’s a start

[vestal hound]

what IDE

[glacial yoke]

vs code

[vestal hound]

hm

I’m not familiar with VSCode so I don’t know how it manages environments

but anyway something is wrong with your path variables

[lavish ferry]

Would the wrapper just be a container?

Also presuming they aren't using a virtual environment they essentially just have everything they have ever pip installed installed and ready in VSCode

Though I don't know how to check the path unfortunately

[vestal hound]

if not virtual

then it's still an environment issue

[vestal hound]

what do you mean

[lavish ferry]

So I would put the image and the card in a container and then reposition the card?

[vestal hound]

yes

something like this

<div class="container">
    <img src="...">
    <div class="card">
        <h1>text</h1>
    </div>
</div>

.container {
    position: relative;
    display: flex;
}

.card {
    position: absolute;
    top: calc(50% - 20px);
    left: (50% - 20px);
    width: 40px;
    height: 40px;
}

off the top of my head

I haven't written frontend stuff for a few months

but this should be it

@lavish ferry

[lavish ferry]

after all my suffering, it should be that easy lol

I will give it a spin as soon as I make it home (got frustrated and left to get food)

Why the -20px in the CSS though?

[glacial yoke]

@vestal hound I even tried to create a new project in the same env, as where the django is installed, and it still didn't work

When I tried to run it

it just gave me the same mistake

[vestal hound]

yeah, like I said

you have a problem in the PATH

[vestal hound]

because

you want it to be centred

right

if it's just 50%

the left edge

will be at the horizontal midpoint

[lavish ferry]

Oh

Yep

[vestal hound]

which means the right edge will be @ the horizontal midpoint + its width

[lavish ferry]

I see, that makes sense

[grave raft]

In django if we have one to one relation can we overwrite the fields we are creating one to one relationshi with ??

[vestal hound]

what do you mean

[grave raft]

class User(AbstractUser): name = models.CharField(max_length=100) phone = PhoneNumberField(unique=True) email = models.EmailField(_('email address'), unique=True) phone_verified = models.BooleanField(default=False) email_verified = models.BooleanField(default=False)

`class TemporaryUnverifiedUserUpdate(models.Model):

user = models.OneToOneField(
    User, on_delete=models.CASCADE) 
phone = PhoneNumberField(unique=True, null=True, blank=True)
email = models.EmailField(
    ('email address'), unique=True, null=True, blank=True)
phone_verified = models.BooleanField(default=False)
email_verified = models.BooleanField(default=False)`

now if i create instance of TemporaryUnverifiedUserUpdate and updates it phone value and save

will it change the value of phone in user instance

[grave raft]

??

[lavish ferry]

Do

```Python
Code

[vestal hound]

it's ``` dude

[lavish ferry]

I know what it is, turns out my phone doesn't do the box I expected from the first one

Oh wrong symbol I see, phone again xd

Does Discord have some kind of escape character?

[native tide]

yeah

basically escapes a lot of things

[bright spindle]

is there someone able to understand django-rest authorization issues

i have full access to the admin and other non-django rest stuff outside of my network

and inside

however the second i start using the django-rest api trough react, i get Unauthorized (applies to all endpoints), unless i'm on my local ip address (192.168.x.x, localhost and 127.0.0.1 won't work)

[thorn igloo]

probably related to CORS

[bright spindle]

from what i see i think the CORS seems to be setup properly

CORS_ORIGIN_ALLOW_ALL = True

CORS_ALLOW_METHODS = [
    'DELETE',
    'GET',
    'OPTIONS',
    'PATCH',
    'POST',

    'content-type',
    'dnt',
    'origin',
    'user-agent',
    'x-csrftoken',
    'x-requested-with',
]

[thorn igloo]

what's the exact error you're getting?

[bright spindle]

Unauthorized: /api/any_endpoint
HTTP POST /api/any_endpoint 401 [0.03, 127.0.0.x:12345]

[thorn igloo]

you have authentication for your endpoint?

[bright spindle]

not that i'm aware of

it only works when accessing from 192.168.x.x

[thorn igloo]

did you configure your headers in react?

[bright spindle]

that isnt something i'm able to check right now

cause i'm only managing the backend

if i try to request to the api endpoint trough postman, and it gives the same error

i think that will isolate it to django

there's this thing tho

DEVELOPMENT_ENVIRONMENT = env('DEVELOPMENT_ENVIRONMENT', default='local')

i have no idea what this is, someone added this before i got the code

[thorn igloo]

i think the issue might be the request header in your frontend

but that's just my thoughts

[bright spindle]

i'll look up with the frontend gyu, and see if there's any issues with the frontend headers

the weird thing is that this worked out of the box the first time i ran it

@vestal hound it works but I can't get it to horribly destroy the size of the image:

<div class="image-container">
    <img class="d-block w-100"
        src="{{url_for('static', filename='images/other/home_encryption.png')}}">
    <div class="card image-card justify-content-center">
        <h1 class="text-center">Data Manipulation</h1>
    </div>
</div>

.image-container {
  width: 100%;
  height: 400px;
  position: relative
}

.image-card {
  position: absolute;
  top: calc(50% - 20px);
  left: calc(50% - 200px);
  width: 24rem
}

img{
  max-width: 100%;
  max-height: 100%;
  display: block
}

Not able to debug this. Please help!

[lavish ferry]

I have been buried by someone who hasn't even shared enough information to actually be helped. 😦

[vestal hound]

huh

I mean

you're stretching the image

[lavish ferry]

Yes. I don't know how to move from this to the desired stretch whilst maintaining the aspect ratio

Which isn't actually a stretch because the image is huge, but the point should still be clear.

[vestal hound]

hold up

I don't get it

what do you expect to happen

[true kernel]

I'm so sorry my man

[lavish ferry]

I want it to resize the image to fit the width whilst maintaining aspect ratio?

[vestal hound]

so the height has to go up?

[vestal hound]

gonna need the traceback to help you

[true kernel]

sure
