Take a look at GraphQL sometime. I am using Django+GraphQL+Apollo and it is crazy fast.

late gale
#

Cool, I heard abotu graphQl but never used it before

#

and what's Apollo

#

never heard of that

dense slate
#

Apollo is a client that helps to cache data from the server, so you can deliver user requests even faster by reducing server requests.

late gale
#

oooh it sounds great

dense slate
#

Well, apollo has a client, and also a server and other tools.

#

But I just use the client with next.

late gale
#

That would make your web more fast and better SEO

#

lol

#

Yea I used react before but I learnt Next and It's very similar to react but when I tried it I compared the performance of react and next and tbh next was faster

#

and it was a basic web just to compare those two

#

I believe next is something we gonna see more in the future

indigo kettle
#

isn't nextjs also just react? They should be similar

dense slate
#

Next is like React+

#

It just optimizes a lot of things.

indigo kettle
#

I see

late gale
#

It's like React the future

is django as backend and reactjs for frontend possible? would it be a good combination for web app as a stack?

Hi guys, why if a try to load media files in deployment with debug = False my media files are not loaded?

#

i'm using django

Some of Next's features are amazing, and when paired with the power of Django, you can make some really nice things

I think it's the meta of web development

actually, meta would probably use express

trying to use selenium for webscraping - but I'm using a lot of time.sleep(). It feels really hacky. Is that normal?

there are APIs for waiting until something loads

which is what I think you want

opaque rivet
#

Yeah, for ajax elements loading

thanks, found the docs for it

what are the things I absolutely must need inside a heroku requirements.txt file for Flask?

#

I keep on getting a H10 app crashed error.... but my Procfile and wsgi.py looks good

#

on my requirements.txt file I have psycopg2, gunicorn, all the Flask stuff...

#

do I need certifi or chardet or requests?

#

also my wsgi.py file is

from app import create_app

app = create_app()```
which might be a little confusing, could this be a problem?

I'm using django with async views and aiohttp to make requests.

I can't find any fix to it and instead found some bug in aiohttp https://github.com/aio-libs/aiohttp/issues/4324 Is there something I can do for it?

with selenium, is it possible to access elements with custom attributes?
such as:
<a href="" my_custom_attribute="my_custom_value">...</a>
is there a way to filter through these elements based off my_custom_attribute?

Hello. Does it make sense to create, edit and delete at the same time in an API? For example in a scheduling application. Just like what you see in the picture. The user can set the times he wants. Finally, after pressing the save button, create if there is no time interval. Update if there is and delete if not in the submission period.

hey guys, i have actually tried the django , and other frameworks, one is there.. um i think the name is cherrypy, but thats not what i really wanted................ i was looking for a technique for putting the python code in the html program, just like we put the js and css code into html

#

and also do you guys know what an arduino is? its basically a pcb through which you can program a hardware, programming lcd screen and other things, you must know it, so i wanted to check if there is a way to connect the arduino to python programs, arduino works on C language ......

Django: what do you folks use for a mutliple select field? The default UI/UX of the default one is terrible. I cannot for the life of me, extract the js/css from the admin for the multiple-select widget and you can't invoke it while not being logged in as superuser.

iron obsidian
#

@ember adder how do you use a custom one though?

#

and a related question: is there a way to display a filter (search box) in a select box of a one-to-many field in the admin?

mild bridge
iron obsidian
#

@mild bridge I tried to use filter_horizontal, but got a message it's only for many-to-many fields?

mild bridge
#

ah I must have misread

#

I'm not sure it is builtin in that case

iron obsidian
#

how do I override though?

mild bridge
iron obsidian
#

is there a list somewhere with all the builtin widgets?

mild bridge
#

cc: @ember adder on overriding frontend for field inputs, custom widgets are generally how it's done

iron obsidian
#

so for something that allows filtering on the frontend, I would need JS. Do I just add a template with JS?

#

is there an easy/semi-standard way to integrate react here (in the admin as a custom widget) or something? since just rendering a small react component would be easiest for me

mild bridge
iron obsidian
#

I see. what exactly do you mean by point to it?

mild bridge
#

I mean just use the standard relative path from any TEMPLATE_DIR

#

Like if your template is in src/core/templates/plugins/multi-select.html you'd do template_name = "plugins/multi-select.html"

iron obsidian
#

and the multi-select.html is just whatever? some html, some JS, some CSS? what's the API for widgets

mild bridge
# iron obsidian and the multi-select.html is just whatever? some html, some JS, some CSS? what's...

I'd have a look through some of the builtin ones for reference:
https://github.com/django/django/tree/main/django/forms/templates/django/forms/widgets

Since widgets are basically just rendered inside forms, they can really just contain anything alongside any valid form input element. You'll need to make sure the type, name and value attrs match the ones in the widget instance passed to the template context, see input.html for reference

iron obsidian
#

but how does django take a value from it. What if my widget is not an input

mild bridge
#

In the vast majority of cases you can just get away with overriding the template for one of these builtin widgets rather than defining your own, I just find it's more explicit to do the latter

iron obsidian
mild bridge
#

I'm not really familiar with how custom widgets play with React, it's probably worth looking at some existing projects for a point of reference

iron obsidian
#

I'm trying to find some

mild bridge
#

I'm sure react-select will render an input element to the DOM at some point, don't really see how else it would function as a form input

#

So (I assume) it'll just be a case of telling React to render your component in the context of your template override

iron obsidian
#

yeah but what does django expect exactly? Do I give it the input an id/name attribute and it takes it from there? is it just an html form?

#

the docs for the admin are a bit sparse

mild bridge
#

Looking at how the default select widget renders things should give you a good point of reference, I'm trying to find an example of how the frontend guys do it at work

#

@iron obsidian as far as I can tell, it's just a case of setting name to your field name, and id to id_ + field name

iron obsidian
#

Thanks. do you know why the id_ + field name is needed?

mild bridge
#

nope 😄 it might not even be needed, I'm sorta just going off some templates that were written for a custom widget recently

#

I don't really work on that side of things

iron obsidian
#

😄 ok, thanks so much!

#

I'm thinking about rolling my own admin with react-admin . I don't know if playing with semi-arcane template stuff in django admin would take less time than just doing it myself

#

@mild bridge do you know if there's a custom channel/discord server for django?

mild bridge
iron obsidian
#

@mild bridge thanks. btw, unrelated, but how do you name a django project? this seems so random..

mild bridge
#

The project as a whole? It doesn't really matter much, naming your apps is what's actually important (i.e. your distinct django apps, not the webapp as a whole)

iron obsidian
#

so what do you call the project? just "project"? "config"? name of company?

is this for webscraping too?

in requests library, I want to do a POST request. How do I know the name of the values etc so I can post them?

For example, I will do a dictionary {"name": "value"}

How do I know what the "name" is. Do I go to the website and do the post request manually, then check what is sent? How do I check what is sent?

grim helm
#

quick question with flask, is there a way to get other body data when submitting a post request?

gritty cloud
grim helm
#

that only gives me input tag things

gritty cloud
#

I'm not that good at flask, but in pretty sure request.form returns a dict

grim helm
#

yeah it returned an immutable dict containing 1 item

#

others just vanished

gritty cloud
#

In ur html

#

The tags you want to submit in the form need to have a name

#

Also make sure you are using correct URLs and methods

grim helm
#

uhh... its fine to generate input tags with name dynamically right?

#

these are all input tags with some names

unknown.png
#

but request.form only gives me this

gritty cloud
#

the rest are disabled

#

i don't think disabled ones get submitted in the form

grim helm
#

:(

#

i dont want user to edit them

#

I just want them submitted..

gritty cloud
#

you can have them hidden

#

see this question

grim helm
#

ouh! that's neato

gritty cloud
# 
<input hidden='hidden' name='foo' value='bar'/>
grim helm
#

noice, works
one last thing

#

i wanna send those coords as well

#

they change dynamically when the user drags the element

#

is there a way to send em

gritty cloud
grim helm
#

ah.. fair enough

gritty cloud
#

then submit them with the form

grim helm
#

so the only way to interact with flask and html is forms

gritty cloud
#

you can also make a rest api with flask

#

and use javascript to interact with it

grim helm
#

mehhh that's overkill.. smth with jinja is what i needed

#

but yeah, this is a clean way

I am wanting to parse through this XML and change the CUSTID within the keywords but I don't want to make changes to the other keywords. I can't make changes to this file because I don't own it to do so.

            <default_value>ABC123</default_value>
        </keyword>
    </keyword_defaults>
#

Parse through it using python.

#

I know a little about ElementTree but I am not sure how I would pick out the specific keyword with the DefaultcustomerID txt that I need to change.

Hi Django Channels doesn't support JWT auth by default using workarounds we can send the token as a query parameter

#

But this exposes the token

#

How do I go about managing this?

#

This is for a group chat, a user can have only 1 group chat

#

So the address would be /group/<groupname>

you can use another cloud provider

replit.com provides cloud hosting and a dev environment

alright thanks a lot

#

i tried deploying a django app into heroku but after too many errors i just gave up

#

i've also tried to try aws but had to stop when it asked for my credit card lol

#

you need to know a bit before you can make stuff

paper briar
#

a lot lol

#

which is why i've resorted to 000webhost

gritty cloud

all ur errors are probably coming from the fact that your procfile is missing or has bad commands

i think i got stuck at the procfile

Hello

#

I am trying to modigy a certain model field after the user sends a post request in the API

# 

class PostList(ModelViewSet):
    permission_classes = [PostUserWritePermission]
    serializer_class = PostSerializer

    def get_object(self, queryset=None, **kwargs):
        item = self.kwargs.get('pk')
        return get_object_or_404(Post, slug=item)

    def create(self, request, *args, **kwargs):
        post_data = request.data
        slug = post_data['title']
        print('THIS IS SLUG', slug)

        print(post_data)

        new_post = Post.postobjects.create(post_data)

        new_post.save()
        serializer = PostSerializer(new_post)
        return Response(serializer.data)

    def get_queryset(self):
        return Post.postobjects.all()
    ```
#

Not going good so far cuz I am getting this error create() takes 1 positional argument but 2 were given

#

and It is coming from this line new_post = Post.postobjects.create(post_data)

#

This is the Post Model ```py

class Post(models.Model):

class PostObjects(models.Manager):
    def get_queryset(self):
        return super().get_queryset().filter(status='published')

options = (('draft', 'Draft'), ('published', 'Published'))

category = models.ForeignKey(Category, on_delete=models.PROTECT, default=1)
title = models.CharField(max_length=250)
excerpt = models.TextField(null=True)
content = models.TextField()
slug = models.SlugField(max_length=250, unique_for_date='published')
published = models.DateTimeField(default=timezone.now)
author = models.ForeignKey(User, on_delete=models.CASCADE, related_name='blog_post')
status = models.CharField(max_length=10, default='published', choices=options)

objects = models.Manager
postobjects = PostObjects()

class Meta:
    ordering =  ('-published',)

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

And this is the post serializer ```py
class PostSerializer(serializers.ModelSerializer):
class Meta:
model = Post
fields = ('id', 'title', 'slug', 'author', 'excerpt', 'content', 'status', 'published')

I want to add django-wiki and django-tagulous to my own project

https://django-wiki.readthedocs.io/en/latest/installation.html

I've read the docs and other sources and I gather I need to create an app in my project and override the django-wiki pages.

But the docs don't explictly list what to override (views, urls).

I splunked the module's code, but I don't recognize the patterns.

What's the first step to integrate django-wiki (which is really a whole django website by itself--i know because I've installed and tested the wiki by itself).

#

_"You can override default django-wiki wiki.sites.site urls/views site implementation with your own: override by setting the default_site attribute of a custom AppConfig to the dotted import path of either a WikiSite subclass or a callable that returns a site instance." _
https://django-wiki.readthedocs.io/en/latest/customization.html#site

This just doesn't make any sense to me...

opaque rivet
#

woah... django jobs are growing quite a bit (or it might be the time of year?)

I remember at the start of this year, there were about ~550 in my country. Now it's 700, pretty good growth

#

also - I have a webscraping module of my webapp. If I want to have it as a seperate service, i'll need to allow it to have its own API right. So, would I setup a new django project and containerize that?

if you can afford I would recommend using Hetzner for example, they provide quite cheap offers for testing/development

proper hinge
#

I have no reason to believe free tiers of Google, AWS, and Oracle (you didn't mention that one) would be unreliable. They just give you fewer resources to work with.

It's not like the classic cPanel free hosts that are stuck in 2010 or whatever.

That's just rumours I saw somewhere. not having first experience with free tiers

The fact that this is Python-only and the syntax is really short AND you can use this with even advanced stuff defo makes this my go-to

Hey, I have been working with a website with Django as backend (like 4-5 s)
I am experiencing a severe latency for the application to fetch data from database and render
is there a way to do client sided rendering by using ajax
i mean something similar to what react does with array.map()

create() got multiple values for keyword argument 'slug' is the Error I get from this code line return Post.objects.create(**validated_data.data, slug=title)

#

This is the full view```py
class PostList(ModelViewSet):
permission_classes = [PostUserWritePermission]
serializer_class = PostSerializer

def get_object(self, queryset=None, **kwargs):
    item = self.kwargs.get('pk')
    return get_object_or_404(Post, slug=item)


def get_queryset(self):
    return Post.objects.all()

def create(self, validated_data):
    print(validated_data.data)
    title = validated_data.data["title"]
    print(title)

    # Once you are done, create the instance with the validated data
    return Post.objects.create(**validated_data.data, slug=title)```
#

When the user sends a post request to create a post, I want to automatically fill in the slug field for them with the current value the title holds.

#

but also make modifications to that title before doing so like: .lower(), .split(' '), .join('-')

what does this mean message=form.cleaned_data.get('message') , does it mean that username's cant be same , cez i cant make same username , and what if i remove this line

Screenshot_97.png
dense slate
#

@dusk portal it means that message becomes the value from your message input on your form after it passes through your form validation.

dusk portal
#

u mean which value

#

can u explain clearly plz plz @dense slate

dense slate
#

value of the input field on your form called "message"

dusk portal
#

ohh so why corey schafer made it message only

#

why not anything else

dense slate
#

I don't know Corey Shafer.

#

As to their intentions, I also don't know.

dusk portal
#

ok so django forms have automatic 3 input , username , password and reenter password why cant i use

#

password

#

can i?

#

and what this means

#

form.cleaned_data, why this

#

what is this

#

what this do

dense slate
#

form.clean_data is validated data from your forms.py

dusk portal
#

ohh

#

how can i make my email also unique same as username cant be same

# 
from django import forms
from django.contrib.auth.models import User
from django.contrib.auth.forms import UserCreationForm

class UserRegisterForm(UserCreationForm):
    first_name=forms.CharField
    last_name=forms.CharField
    email=forms.EmailField()

    class Meta():
        model=User
        fields=['first_name','last_name','email','username','password1','password2']```
dense slate
#

Check if the email exists, then return a message if so.

#

You could do a quick lookup to see if the user email exists already before the function continues.

dusk portal
dense slate
#

How would you look anything up? You can query the DB.

dusk portal
#

yes in my admin page users are getting registered

dense slate
#

Do you know how to query the database to get a user, for example?

dusk portal
#

u mean login from those userrs

#

idk i have to learn that

dense slate
#

Keep it up, you'll get there.

#

Better you understand what you need to do, and then learn how to do it following the tutorials.

#

so figure out how to search the DB for a specific variable.
Such as:
user = User.objects.filter(email=email_address)

dusk portal
#

oh

dense slate
#

If the user exists, return a message and don't create the user.

dusk portal
#

i am coding at django

#

from 5th of June

#

That's ok, keep it up.

Hi, are there certain html tags that are completely safe , that is I can let users use those tags in their posts? I am making a django site where users can use (custom) bold, italicize and image tags which are not escaped. Is this safe?

dense slate
#

Not really. From what I've read, unless you know the data is absolutely 100% safe, like your own DB or function return messaging, you shouldn't use it without some kind of custom markdown implementation.

#

But there are libraries out there to take care of that.

vernal thistle
dense slate
#

Google django markdown library?

#

I only remember TinyMCE

vernal thistle
#

Is TinyMCE safe? I used it and it didn't even close unclosed tags.

dense slate
#

It might not be, I don't use those libraries. You'll have to check on that.

vernal thistle
#

All right.

Hello. I’m trying to display images from a folder in an HTML webpage. How do you form a folder path with a variable file name? Could anyone help with this?

#

I’m using pycharm flask

'default': {
        'ENGINE': 'django.db.backends.postgresql',

        'HOST': 'db',
        'PORT': 5432,
    },

The Host refers to my postgres container. But what if I want to run my webapp locally and use localhost?

Umm… no I’m not trying to print the path. I want to display images that are stored in the static folder.

But the name of the file is a variable

yes, so you can form variable paths like that, which you can then pass to your html template

In my Django project is it better to not use the Django ORM?

Made a whole backend for an app, now came across articles saying the ORM is bad

hi anyone FLASK expert here? I have page A with form search, form points with payload in URL to page B so page B for example has ...?query=Cats. Ok cool, I have some dummy data in my main_run.py like:

dummy_data = [
  {
    'name': 'Dog',
    'age': 2
  },
  {
    'name': 'Cat',
    'age': 1
  }
]

and I want to show in page B data of query from link, if it is a Cat, then it will display something like {{ data[0].name }}. I tired in my page B do smth like:

@app.route('/pageB?q=<LINK_DATA>')
def page_b(LINK_DATA):
  if LINK_DATA in dummy_data:
    LINK_DATA = LINK_DATA
  else:
    LINK_DATA = 'Dog' # just for test
  return render_form('page_b.html', data=LINK_DATA)

And I get an error like I forgot provide data for LINK_DATA

quick cargo
#

generally, ORMs are good

#

people poo poo ORMs because it takes away the need for learning the raw SQL which often can lead people to writing less than good queries just because they dont necessarily understand whats going on behind the hood.

#

in terms of management, ORMs are great, combined with automatic migrations it makes maintaining the code base considerably easier

#

but to use them well you do still want to have some SQL / applicable knowledge in the DB design first so you're able to better visualise how the system is going to produce the queries and how that's going to affect performance and efficiency etc...

dense slate
#

Yea they make my life easier for sure.

Hi, i would like to do an event like discordy but with a website. So i. e. when a value or something changed on a website then it will trigger my pthon code. I was thinking to use a while True loop so it checks if the value is the same as the previous request, but i think that's a bad way to do that. Do you have any ideas?

#

It seems like a common sense question and I think the answer is yes, but I still wanted to ask.
If the internet speed is slow, then does it mean GET and PUT request would also be slow?

proper hinge
#

Those involve sending data over the internet. Therefore, they are affected by the speed of the connection. So the answer is yes.

#

However, when discussing slow internet, it usually means low bandwidth. If the requests don't send a lot of data (e.g. only a kilobyte), then you wouldn't notice.

naive rock
#

ok that makes sense so something like GET and PUT wont get effected if it's sending and receiving couple of kilobytes of data, when the internet itself has couple of mb in download and upload.

#

Thanks!!

How can I add a button that when I click it, it will print ("Hi") in console (Django)

i am working on a projet in django , all is working fine , but after adding modals with ajax i have a message like this "broken pipe" ? can anyone explain me , i really don't know how to fix it please!

west peak

          <button type="submit" name='mybtn2'>Download results in Excel</button>
        </form>

all that I want this to do is print ('hello') in console.

views.py

    if request.method == "GET":
        print("hi")

how can I go about doing this?

inland oak
#

They offer things like throttling limit there for example too (to limit amount of requests from same ip against abuse)

arctic wraith
marble spade
#

even if its post tho, it doesn't really work

#

it refreshes the page

#

and it doesn't say "hi"

arctic wraith
#

do you want just a button that print hi ?

marble spade
#

for now, yes

#

don't wanna use js

arctic wraith
#

ah ok

#

you can use <a href="">....</a> ?

marble spade
#

I don't want to redirect to a new page tho

arctic wraith
#

and css to have like button

marble spade
#

eh

#

why when I refresh the page, does it run that function?

#

and like how can I stop that

without refresh you want

Use whatever works best with what you're doing

Backend's always better, if you're dealing with a big project

calm plume

yea going for a big project

That's what I prefer, personally

But it's your choice

calm plume
#

It's very dependent on 1, your preferences, 2, exactly what your project is

#

interesting

#

Like, if your backend is just a REST API that's deployed on a different subdomain, you wouldn't do routing there

you would then need to incorporate an API for passing data to and from

make sure that that html file is in a directory called templates in the same working directory as your main.py

It can be made accessable by your localhost only

so basically what I am trying to do is to pass name and surname in the url

when the user puts them in the field forms

but instead I get errors and cant find a way to fix it

#

like, how can I specify those values? I tried googling

outer apex
# hollow apex like, how can I specify those values? I tried googling

You specified show_info's url with /user/<name>/<surname>, so when you use url_for with show_info, you need to pass in name and surname as kwargs.

I suspect that there's no reason for you to include name and surname for the show_info url, since you're getting those from the form.

Hey guys I tried to create a database using sqlalchemy
But the class isn't providing any of the methods or functions while calling it.
Even after I imported that class again

The method of that imported class

Like while importing pandas as pd
We can use pd. read_csv so that's the method or function of that pandas class

Is it possible to store data in cache per user session?
Like I fetched an API with a lot of data and I need to access it everywhere until user browse...

so... just store user session key in it 😉 or something like that

just make sure you output valid, not outdated data

class Profile(models.Model):
    user=models.OneToOneField(User,on_delete=models.CASCADE)
    image=models.ImageField(default='notactive.jpg',upload_to='profile_pics')``` why  we r adding upload_to and what's the difference between ForeignKey and OneToOneField
#

plz

inland oak
#

for example you have Profile

#

every User instance should be having its own Profile instance and only one

#

it makes it perfect (one to one) relationship

#

but for example you created Message, there can be a lot of messages to one user

#

that would be already perfect for Foreign key relationship (one to many)

#

Foreign key is used to attach a lot of objects to one object

#

OneToOneField basically extends the same model

dusk portal
#

@inland oak

if request.method=='POST':
   form=UserCreationForm(request.POST)

if form.is_valid():
    form.save()
  message=form.cleaned_get('message)

So tell me why we r using this last time after its saving info to the db

I encounter this code using Flask in Python. This is the Jinja used html file. I wonder if the word "content" in {% block content %} is a reserved word or any other coder determined word.

{% extends "base.html" %}

<div class="container">
  <h1 class="title">Welcome, Name!</h1>
  <a href={{ url_for('download') }}>Download Your File</a>

<div style="background-image: url('{{ url_for('static', filename='img/{{ my_name}}') }}'); ">

Notice how {{my_name}} doesnt work in link in .html file; but works if I put it in <h1> tags for example. Why. See how it destorys my var: ???

Hi, is there any method to invalidate sessions in all devices using jwt (Django)?

#

For example, when changing passwords

inland oak
#

when they aren't matching, I deny jwt decoding

#

a bit silly approach tbh

#

but hey, it works

safe kindle
#

Haha ok, I'll keep it in mind, thanks

inland oak
#

verified with signature that they were not tampered with

#

they were not changed

#

when you decode JWT

#

you verify that the data inside was not changed

#

so... you can keep safely for example something like

{
  "User Level Permission": "10",
  "IsUserAuthorizedToUseThingX": "True"
}
#

storing hashed password is essentially the same

Ohh, I see...

How do I use persistent ClientSession with django? I need to use aiohttp and some async libs like discord.ext.ipc but I can't figure out how to use them...

I've been finding any guide or reference from past week but unable to find one, can't find proper docs in django official too... (Note I know how to create basic async views but that's not the issue with me) Thanks :)

I think my experience has to do more with the framework

#

it doesn't do things the 'pythonic' way

#

it's like you are using a different language

#

in the other hand in flask you can make your app in seconds and just hit flask run or python app.py and it will just run

#

in django you have to make commands over and over and over to just get things to work

#

flask-admin bluh bluh bluh. There's a app and a project. 7+ .py files created with the project

quick cargo
#

because you shadow your function names

#

you can only have one function with a given name

#

two functions in the same space with the same name is called shadowing and means that only the last function will be the function python uses / registers

obtuse whale
#

ok 🙂 thanks for the heads up

vestal hound
#

I don’t think shadowing is the right term here?

#

it’s more reassignment right

#

shadowing is about scopes

#

like the first function will never be accessible again so it’s not shadowed, just gone

inland oak
quick cargo
# vestal hound kinda nitpicky but

I guess? But then you use the term shadowing when say someone does all = foo and it shadows the all() function, in the same sense it's the same thing?

vestal hound
#

if it was in global scope

#

this would be shadowing

# 
a = 1

def f(a):  # this shadows a from outer scope
    pass
quick cargo
#

I guess true

#

I guess I just roll with pycharm's definition of it 😅

Hi, I'am doing an app with DRF, but I'am stuck on one thing.
I created API that can return JSON from model, with filtering and sorting...
Now I wanted to handle POST request, that will update DB records from static hardcoded url, which returns JSON as well.
serialiser.is_valid() returns True. But then, as I want to .save() I got this. "django.db.utils.IntegrityError: UNIQUE constraint failed: api_book.id"
Anyone could help on it? I got confused...

How do I include a module in webpack if I don't use it in any of my own JS modules?

#

The module in question is from npm - it's just something from the front end that works without me needing to interact with it in any way with JS

I probably could just import it anyway so webpack picks it up, but that seems like a hack considering I don't actually need to use it directly.

right, i am not too familiar with tkinter so i can't really say if it's possible to make a gui like that, but if you are good with html, css and javascript, you can make "desktop apps" with html css as the frontend part and use the eel library to connect your python code to the UI. or you can look at electron js i believe

not sure if electron js lets you use python

timber thorn

ok so its possible to connect python with html and css?

you need to have your media url in your path, try adding this to the end of your main urls.py
if settings.DEBUG:
urlpatterns += static(settings.STATIC_URL,
document_root=settings.STATIC_ROOT)
urlpatterns += static(settings.MEDIA_URL,
document_root=settings.MEDIA_ROOT)

Anyone here been able to load @font-face into Django in css file?

Here's a sample for submitting login data as form through a flask api to get it from flask using request.form

app/static/js/script.js

xhr = new XMLHttpRequest()
xhr.open("POST", "/api/login", true)
xhr.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
xhr.send(`username=${user}&password=${pass}`)

xhr.onreadystatechange = function() {
    if (this.readyState === XMLHttpRequest.DONE && this.status === 200) {
        // Here's the JSON response from the Flask API
        let resp = JSON.parse(this.response)
    }
}

app/app.py

... # Your previus Flask code
@app.post("/api/login")
def api_login():
    print(request.form["username"], request.form["password"])
    return jsonify({"status": "success"})

#

I know that @font-face can be brought into css regularly. How can this be done with Django?

I have uploaded woff font files into project/static/fonts.

css file has the following

@font-face {
  font-family: 'Mont';
  src: url("/fonts/font.woff2") format("woff2"),
    url("/fonts/font.woff") format("woff");
    font-weight: 900;
}

h1, h2, h3, h4, h5, h6 {
    color: #444444;
    font-family: 'Mont', sans-serif;
}

So, I'm pulling the font into the heading tags. The @font-face style is at the top of the css file.

I am seeing a 404 in the console.

GET /static/articles/fonts/font.woff HTTP/1.1" 404 1831

The files are there. But they are not coming through. What am I missing?

anyway, a lot of applications use Electron to run their frontend application with chromium

#

no idea how to interact with that from Python, but there are probably some other libraries like that if you specifically want to build something with a browser integration

#

but there are lots of GUI libraries for Python

Hello Friends, I have a question about QueryDict type in Django.... So I have a form wich uses the select tag and so I can send multiple inputs with a POST.
I don't understand why python doesn't returns all the values from the dict when I try to read the key.... it returns only the last element on the list....

Screen_Shot_2021-07-04_at_13.21.16.png
#

when I do dict['1'] It should return -> ['1_1', '1_2'] but it's only returning '1_2'....as a string.... any ideas why? is this a bug?

#

Alright never mind.... OMG why Django 😦 so actually Django returns the last value from a list when you do it this way.....
https://code.djangoproject.com/ticket/1130
I hate it when Django objects work differently from Python objects.....

view.py

def add_city(request):
    data = dict()

    if request.method == 'POST':

        form = AddCityForm(request.POST)
        city = request.POST.get('country')
        duration = request.POST.get('duration')

        if form.is_valid():
            form = form.save(commit=False)
            form.request.session['duration'] = duration

        city = request.POST.get('country')
        duration = request.POST.get('duration')
        something = request.POST.get('something')

        if form.is_valid():
            form.city = city
            form.duration = duration
            form.something = something
            form = form.save()

forms.py

class AddCityForm(forms.Form):
    duration = forms.ChoiceField(widget=forms.RadioSelect(attrs={

without virtual environment I can't run django?

warm igloo

Sure you can.

thorn igloo
timber thorn
#

wasn't good

#

not what I was looking for

thorn igloo
#

how?

#

ok then,

#

if you don't want to use that, i guess you can just use the standard python libraries for gui

timber thorn
#

I now use electronjs

thorn igloo
#

how do you connect it to python?

timber thorn
#

not at all

#

I use electronjs!!

#

JavaScript with html and css

#

the bad thing is I have to convert my whole python code to js

thorn igloo
#

wasnt your original post about connecting your python to an html gui?

timber thorn
#

yes cuz I thought this is my solution

#

but it wasn't

thorn igloo

Looking for help using @font-face in a css file in Django. I have uploaded woff/woff2 font files into project/static/fonts.

css file has the following

@font-face {
  font-family: 'Mont';
  src: url("/fonts/font.woff2") format("woff2"),
    url("/fonts/font.woff") format("woff");
    font-weight: 900;
}

h1, h2, h3, h4, h5, h6 {
    color: #444444;
    font-family: 'Mont', sans-serif;
}

So, I'm pulling the font into the heading tags. The @font-face style is at the top of the css file.

I am seeing a 404 in the console.

GET /static/articles/fonts/font.woff HTTP/1.1" 404 1831

The files are there. But they are not coming through. What am I missing?

how does flask google oauth work?

#

i can't find any website with good code (i copy-paste the code to get it to work, then edit it to be right for my use)

#

i even cant fetch title

it's null when i used self.content in str

west mulch

you haven't created model User but linked a foreignkey to it

ionic raft
dusk portal

it's django auth

for some reason it's trying to get /static/articles/fonts/font.woff

oops, typo

there

ionic raft

#

@thorn igloo do code at django too?

thorn igloo
#

no i dont

thorn igloo
ionic raft
thorn igloo
#

alright

ionic raft
#

Still not working...I'll try a server restart and hard refresh on the page. If this doesn't work I will have to look at settings.py and see if I can resolve through forcing a mapping

dusk portal
ionic raft
# thorn igloo alright

It's weird....because console shows mapping to the folder I've configured in url in css file. However, it returns a 404....

#

Nope...not working...Let me try and shift folder structure...

ionic raft
thorn igloo
dusk portal
#

oh

ionic raft
thorn igloo
#

yea

#

wait, it needs to be in static

ionic raft
#

OK. I'll refactor back to static.

#

This is what I had....have restored to this:

unknown.png
# 
@font-face {
  font-family: "Mont";
  font-style: normal;
  font-weight: normal;
  font-stretch: normal;
  src: url('fonts/font.woff2') format('woff2'), url('fonts/font.woff') format('woff');
}```
thorn igloo
#

the articles folder in static

ionic raft
#

Like this?

unknown.png
thorn igloo
#

yes, now what does it say?

ionic raft
#

OMG....MY HERO!!!!

ionic raft
thorn igloo
#

awesome

ionic raft
#

You're amazing....This was a WEIRD one!

#

Of course....oh my goodness...
Well, Django is awesome to learn...and it has some fun idiosyncracies. Loving it...but whoa....

#

I've literally been banging my head on that for about 4-5 hours

#

I can't believe I didn't think to move the fonts folder inside articles/static...face palm

thorn igloo
#

i dont know why the /fonts/... url automatically looks in articles tho

ionic raft
thorn igloo
#

hhm, i mean you have to understand at some point in order to change it

ionic raft
#

In a way though...it's basically saying, look to the css file, and then assume fonts will have their own folder inside the same folder

#

Now, I'm wondering if I'll be able to centralize fonts, base.html and css files in the project folder...but so far all I've gotten is "outside folder hierarchy" errors.
I imagine that I'll either have to accept duplication for such files across apps, or I'll work out how to setup that mapping

Hi I just recently finished my school management app

#

It uses a three user system

#

Log-in with Pepanni and password alexdiana to access Primary admin

#

John and password favourgilead to access teacher admin

#

Sharon and password favourgilead to access student admin

#

It's my first project so I'd love to know what you guys think.

#

😅

Looks like a good start.

  • If this really is a site for primary education then even the colors look appropriate. (^_^).
  • I like the size of fonts, icons and buttons, which can be tricky.
  • Clicked around and everything seems to be working nicely.
    One thing I would think differently is Student List > Paid. While the switch works nicely as a GUI element, I don't like the lack of safeguards. This information is import and must be correct. I just clicked Luke's payment as $0, and I'm pretty sure he's going to get kicked out of school. hehe

Hello everyone,
I'm trying to make a function that retrieves the productStockLevel: "inStock" that is in the data variable on the auchan site on the page of an item.
I'm stuck because I can't access the data variable and I searched on the internet but I couldn't find anything or maybe I used it wrong.
For the moment I can only get the script[4] where my data variable is.
If someone can help me I would be very grateful I've been working on it for 1h30.

Translated with www.DeepL.com/Translator (free version)

code:

import requests
from bs4 import BeautifulSoup

session = requests.session()

def get_stock():
    global session
    productPage = 'https://www.auchan.fr/power-a-etui-de-protection-silhouette-pikachu-nintendo-switch/p-c1334312'
    response = session.get(productPage)
    soup = BeautifulSoup(response.content, "html.parser")
    scripts = soup.find_all('script')[4]
    print(scripts)

get_stock()

Hey Kylar. I'm new to this community and I did offer advice for your project. That said, I was looking in the FAQ for an answer to another question and I noticed this:

"Can we have a channel to show off projects...?
[...] You're welcome to showcase your projects in our off-topic channels..."

Just so you know--before we both get Mod-Clobbered. (>__<)

Hello, I am learning flask flashing. But I encounter a code like this, which is in the documentation https://flask.palletsprojects.com/en/1.1.x/patterns/flashing/

<!doctype html>
<title>My Application</title>
{% with messages = get_flashed_messages() %}
  {% if messages %}
    <ul class=flashes>
    {% for message in messages %}
      <li>{{ message }}</li>
    {% endfor %}
    </ul>
  {% endif %}
{% endwith %}
{% block body %}{% endblock %}

But in the python file there is no get_flashed_messages() pass into this html file. How does this happened? How does Jinja2 read this function from nowhere?

But how does jinja read that function? Also I did not import it.

Give me a moment...will look up a snippet I have...

I spent a couple of months with Flask...so have accomplished this before

OK....so here's how I used Python to send the flash...
