My css styles don't connect to my django-written website
Some styles were connected without any problems, but I managed to make only one section, as they stopped connecting and my entire site began to look like a document in word I have already searched for similar problems here, tried the solutions given; I also searched for how to connect styles, etc. Unfortunately, I did not find a solution to my problem, so I am writing here Base.html {% load static %} <!DOCTYPE html> <html lang="ru"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>{% block title %}{% endblock %}</title> {% block css %} <link rel="stylesheet" href="{% static 'css/_normalize.css' %}"> <link rel="stylesheet" href="{% static 'css/main.css' %}"> {% endblock %} </head> index.html {% extends './base.html' %} {% load static %} {% block css %} <link rel="stylesheet" href="{% static 'css/main.css' %}"> {% endblock %} {% block title %} Главная {% endblock %} {% block content %} <section class="hero"> <div class="container hero__container"> <div class="hero__content"> <div class="hero__text"> <h1 class="title hero__title"> Центр подбора лечения от&nbsp;алкоголизма, наркомании и&nbsp;других зависимостей </h1> <h4 class="title hero__subtitle"> Мы&nbsp;приходим на&nbsp;помощь в&nbsp;самых нелегких ситуациях и&nbsp;точно знаем как можем помочь и&nbsp;пациенту, и&nbsp;его близкому окружению. </h4> </div> <button class="btn btn-reset hero__btn"> <a href="#" class="link-reset hero__link">Бесплатная консультация</a> </button> </div> <div class="hero__image"> <img src="{% static 'images/hero/hero-img.png' %}" … -
Can't send files to ChatConsumer in Django Channels
I'm having an issue with sending files to a handler in ChatConsumer using Django Channels. I have two consumers, ChatConsumer and GroupChatConsumer, for handling direct messages and group messages. I want to send files to ChatConsumer or GroupChatConsumer based on whether a group exists or not. If the group doesn't exist then file should go to ChatConsumer I'm sending the files using channel_layer.group_send through views. Keep in mind I have the same handler name in ChatConsumer and GroupConsumer but despite changing those the issue persists What i have tried: Added print statements right after group_send to confirm if they execute without any error and they do! I also added logging inside ChatConsumer to see if any file or message is recived but there isn't! Ensured if the websocket connections are active and they are! So how can I verify if a message is successfully sent to ChatConsumer? Why is the consumer not receiving any messages? My code: https://github.com/Kioshi5581/djchat -

Django: Html select with onchange action (without using form) and pure Javascript: redirect with code 200 but page not loaded
I have a select box in my template that reacts on changes with the onchange function that sends the selected value to the Django view. The view gets the required data from the database and should display them. main.html {% block content %} <select class="form-select form-select-lg mb-3 categorySelect select" name="categorySelect" aria-label="Select category" onchange="getSelectedId(value)"> <option value="None">Select category</option> <option value="all">All</option> <option value="cat1">Category 1</option> <option value="cat2">Category 2</option> </select> {% endblock %} select.js function getSelectedId(selectedValue) { const value = selectedValue; const endpoint = "/all/select"; fetch(endpoint + "?select_id=" + value) .then() .then(response => { }) } views.py def select(request): select_id = request.GET.get("select_id", "None") print(select_id) if select_id.__contains__('None'): return render(request, "home/main.html" ) elif select_id.__contains__('all'): return redirect(reverse('all:probe_list')) elif select_id.__contains__('cat1'): selected = "Category 1" config = RequestConfig(request) resultTable = AllProbesTable(Probe.objects.filter(category = "cat1")) config.configure(resultTable) return render(request, 'all/selectResults.html', {'table':resultTable, 'selected': selected}) I get the correct select_id in the view and the I get a 200 from the redeirect but the page is not changing (similar to This question). I understand that I need to add a reload such as "location.reload()". I added this to the template I am redirecting to but this did not work. Is there any way to trigger a reload or is there another way to implement a … -
Is Enumerating Through Multiple Categories in API Tests a Good Practice? Alternatives for View Testing?
I'm currently writing tests for my Django application using pytest and pytest-django. One of my tests involves creating multiple category instances and verifying that they are correctly listed in the API response. Here’s a snippet of the test: @pytest.mark.django_db def test_auth_user_can_list_categories(auth_client, category_factory): categories = category_factory.create_batch(5) url = reverse("category-list") response = auth_client.get(url) assert response.status_code == 200 for i, category in enumerate(categories): assert response.data[i]["id"] == category.id assert response.data[i]["name"] == category.name In this test, I’m creating 5 distinct categories and then using enumerate to loop through them to verify that each category is correctly listed in the API response. I’m wondering if this approach of enumerating through the categories to match them with the API response is considered a good practice. Are there any better or more efficient ways to test this scenario? Specifically, are there alternative strategies for view testing that could offer more robust or scalable solutions? I’d appreciate any advice or best practices on how to improve this test or alternative methods to achieve the same results. -
Background-image in CSS url blocked by Opaque Response Blocking
I use a background-image like this: <style> .bg-image { background-image: url("{{ instance.background.url }}"); } </style> but the request gets blocked A resource is blocked by OpaqueResponseBlocking. Displaying the image the 'normal' way with <img src="..."> works perfectly. I tried setting a header in CORS-Configuration like: Content-Type: text/css but that did not change anything. I did specify the origin domain and allowed GET, PUT, DELETE, POST and HEAD. -
Django Session variables not visible after login
I am developing a hospital site. patients are allowed to login and book appointment. When a patient logs in, a sessions is initiated and saved.

order_by combined column in django
I have two models who inherit from another model. Example: class Parent(models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False, verbose_name="ID") class A(Parent): name = models.CharField(max_length=255, verbose_name="Name") class BProxy(Parent): target = models.OneToOneField('B', on_delete=models.CASCADE) class B(models.Model): name = models.CharField(max_length=255, verbose_name="Name") My query currently looks like this: Parent.objects.all() In my serializer, I check which subclass the parent object is (hasattr(obj, 'a')) and then use either name = obj.a.name or name = obj.b.target.name for the serialized data. But now I would like to sort the queryset for the output. Normally I would use Parent.objects.all().order_by('name') here. But the name is in the subclasses. Would it be possible to combine the “name” columns of the two subclasses and then sort by them? Or is there another solution? -

How do I create Stripe-like DB ID's for Django models?
Core problem I'm trying to solve: I want to have ID's on my database models that are similar to Stripe's (i.e. of the form aaa_ABCD1234 where the ABCD1234 part is a ULID and the aaa_ part is effectively the table name (or a shortened version of it)). This feature has saved me a ton of time in debugging Stripe integrations and I'd love for users of my systems to be able to have those same benefits. However, I know taking the nieve approach and just a string as a primary key on a table is terrible for performance (mostly indexes and consequently joins as I understand it) so I want to take advantage of the built in UUID datatype in the DB to store only the ABCD1234 part in the DB and not store the aaa_ part since that will be identical for all rows in that table. Where I stand today I'm currently thinking of doing this as follows: Have a "private" field on the DB model (call it _db_id?) that is the UUID and technically the primary key on the model in the DB. Have a GeneratedField that takes the above private field and prepends the table prefix … -
How to convert query string parameters from Datatables.js, like columns[0][name] into an object in Python/Django?
I'm using DataTables.js and trying to hook up server-side processing. I'm using Django on the server. Currently, the data to Django looks like: {'draw': '1', 'columns[0][data]': '0', 'columns[0][name]': 'Brand', 'columns[0][searchable]': 'true', 'columns[0][orderable]': 'true', 'columns[0][search][value]': '', 'columns[0][search][regex]': 'false', 'columns[1][data]': '1', 'columns[1][name]': 'Sku', 'columns[1][searchable]': 'true', 'columns[1][orderable]': 'true', 'columns[1][search][value]': '', 'columns[1][search][regex]': 'false', 'columns[2][data]': '2', 'columns[2][name]': 'Name', 'columns[2][searchable]': 'true', 'columns[2][orderable]': 'true', 'columns[2][search][value]': '', 'columns[2][search][regex]': 'false', 'order[0][column]': '0', 'order[0][dir]': 'asc', 'order[0][name]': 'Brand', 'start': '0', 'length': '10', 'search[value]': '', 'search[regex]': 'false', '_': '1725412765180'} (as a dictionary) However, there's a variable number of columns and order values that might come through. So I'd like to convert all of this into a few key variables: start length search value search regex draw array/list of column objects array/list of order objects But I don't know a lot of python -
JWT token claims in Django Rest Framework
I am using rest_framework_simplejwt, and would like to add extra information to the access token returned for authorization purposes. Following along with https://django-rest-framework-simplejwt.readthedocs.io/en/latest/customizing_token_claims.html I am able to modify the access token. However I want to be able to add a claim based on the initial POSTed login. For example: curl -X POST -H 'Content-type: application/json' -d '{"username": "user1", "password": "supersecretpassword", "project": "project1"}' https://myurl.com/api/token/ I would like to be able to add project1 to the access token. Is there a way to add extra information in that manner? -

Heroku Django performance issues - Request Queuing
We run a Django application on Heroku, and lately we've been seeing some performance issues.

Why are requests queued? Is this a horizontal scaling issue? It does not seem like the Python app itself is Any help welcome! Kind regards, Martijn -

How do I correctly render a django-view using Apphooks in django-cms?
I am building a project in Django CMS using version 4.1.2. Part of the project will be a news-section, for which I defined a Django model like this: # news/models.py from django.db import models from django.utils import timezone from djangocms_text_ckeditor.fields import HTMLField class Post(models.Model): title = models.CharField(max_length=200, verbose_name="Title") text = HTMLField(verbose_name="Text") user = models.ForeignKey('auth.User', on_delete=models.CASCADE, verbose_name="Author", blank=True, null=True) date = models.DateTimeField(default=timezone.now, verbose_name="Date") class Meta: verbose_name = "Post" verbose_name_plural = "Posts" def __str__(self): return self.title I want this model to be a django model instead of handling it with CMS-Plugins, so that editors can manage Posts using the admin-interface and to make it easier to use things like pagination. I have a little experience with Django, but not really with Django CMS. However, on the page displaying the news-section, I also want to have a header, a sidebar and a footer that should be editable using the CMS-Toolbar. Therefore I made an Apphook - from what I understand this should allow me to integrate the news-page with Django CMS. This is what my Apphook looks like: # news/cms_apps.py from cms.app_base import CMSApp from cms.apphook_pool import apphook_pool from django.urls import path from django.utils.translation import gettext_lazy as _ from news import views @apphook_pool.register … -
Django Template: How to connect chat script passing in Django Tag with JavaScript?
I'm working on a Django project where I need to conditionally render and execute a chat script based on user cookie consent. Here's what I've got so far: In my Django template, I have the following snippet: {% if page.page_type.chat_script %} {{ page.page_type.chat_script|safe }} {% endif %} This snippet is responsible for rendering a chat script (something like chat script code) which is set via the Django admin panel. However, I only want this script to execute if the user has accepted all cookies. I already have a separate JavaScript file (cookies_configuration.js) that handles cookie consent and injects various scripts into the head or body once consent is given (it works pretty fine when I use it with normal different scripts placed in other files). Here's a simplified example of how that injection looks (a little snippet from my code): 'injections': [ { 'location': 'head', 'code': 'initGoogleAnalytics()' }, ] Now, I want to do something similar for the chat script—essentially wrap the Django template snippet in a function like initChatScript() and then call this function only after cookie consent is granted. However, I'm not sure how to dynamically include and execute this Django template code within the JavaScript function. I've … -

Overriding DRF ListAPIView list() method
I have a DRF Project, wich has a ListAPIView for a model called Category. This model, has a ForeginKey to itself named parent_category and with related name of subcategories. I want my URLs to behave like this: get a list of Categories with no parent: example.com/api/categories get a list of subcategories of an object with some id: example.com/api/categories/{id_here} models.py: class Category(models.Model): name = models.CharField(max_length=100) parent_category = models.ForeignKey('self', null=True, blank=True, on_delete=models.CASCADE, related_name='subcategories') views.py: class CategoryList(generics.ListAPIView): queryset = Category.objects.all() serializer_class = CategorySerializer And I have no idea how to write my urls.py. Do I need DRF routers? or Django path works fine? I don't know which to choose or how to use them for this project. I thought if i override ListAPIMixin's list() method, it would work, but I don't even know what to write in that.
