Error while adding an image to the db using django panel in production. Using docker, nginx and gunicorn
I did a page with django which give the possibility to the user to access to the django admin panel to add an image into the page. The image is being pull to the database with the models of django. class Images(models.Model): left_arrow= models.ImageField(upload_to="general/arrow/") right_arrow= models.ImageField(upload_to="general/arrow/") open_complete= models.ImageField(upload_to="general/complete/") close_complete= models.ImageField(upload_to="general/complete/") untick= models.ImageField(upload_to="general/tick/") tick= models.ImageField(upload_to="general/tick/") This was working perfectly in development because i had this command in the urls file: if settings.DEBUG: urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) In production i had to errase those lines. The media files that were already in the database are being showed perfectly well, the static and media files are working perfectly.

Setup Heroku to run Django unit tests in parallel
I am currently working on a Django project and have deployed my application on Heroku. I want to optimize my CI/CD pipeline by running my Django unit tests in parallel (I'm using pytest and I'd like to keep using it). Could someone guide me on how to properly set up parallel test execution? The following is my app.json file: { ...

Django Admin TabularInLine bad table shown
I have a Django Admin List-Change module with a TabularInline, where the table head is shown correctly, but every row is wrong, as if it were a StackedInline.

How do I show the error to the user when initializing the Django form?
I'm trying to do the following. The form should upload a text file. If it is not present, the form should not be loaded. An error should appear instead. class SemanticAiForm(forms.Form): semantic_folder = configurate.AI_DATA_FOLDER semantic_files = 'ai_openai_fresh_news.txt' def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) semantic = self.get_semantic() if semantic is None: self.add_error(NON_FIELD_ERRORS, 'No data') else: self.fields['order'] = forms.CharField(widget=forms.Textarea()) self.fields['order'].initial = semantic.system_content def get_semantic(self) -> Union[SemanticTxt, None]: """ Получает объект SemanticTxt с прочитанным файлом параметрической конфигурации.

If there is no file, on the contrary. Django reports: 'SemanticAiForm' object has no attribute 'cleaned_data' I'm trying to do something else. If there is no file, display an error in the template. And don't show the form. What am I doing wrong? -
Force django not to redirect after password change?
Maybe this is a stupid question. I have a simple Django app and when I change the password (success or not) I want to stay on the same page (I wanna manage with JS the messages). So I no wanna redirect at all at path (password_change/done). Is this possible? This is the views file that I tried, I tried to return None hoping it will work. @login_required def ChangePassword(request): form = ChangePasswordForm(request.POST or None) if form.is_valid(): form.save() messages.success(request, 'Your password was successfully updated!') else: messages.error(request, 'something happened!') -
Why is POST request to /api/posts/ returning 401 Unauthorized in Django DRF despite valid token in Axios headers?
Problem: I'm facing an issue with a 401 Unauthorized response when making a POST request to /api/posts/ in my Django Rest Framework (DRF) backend from a React frontend. The Axios instance in React uses an interceptor to add a Bearer token (stored in localStorage) to the Authorization header, but the request still fails. The DRF view uses generics.ListCreateAPIView and requires authentication with permissions.IsAuthenticated. The POST request fails, even though the token is present in the headers. I've checked both the frontend and backend configurations, but the issue persists. The urlpattern is posts/. But from frontend it all the urlpatterns for the api(Django app) can only be accesed through /api/urlpattern/. Django DRF Backend Code models.py class Post(models.Model): author = models.ForeignKey(User, on_delete=models.CASCADE, related_name='posts') body = models.TextField(max_length=240) media = models.ImageField(null=True, blank=True) created_at = models.DateTimeField(default=timezone.now) def number_of_likes(self): return self.likes.count() def number_of_comments(self): return self.comments.count() def get_created_at_in_user_timezone(self, author): user_timezone = pytz.timezone(author.profile.timezone) return self.created_at.astimezone(user_timezone) class PostSerializer(serializers.ModelSerializer): author = serializers.StringRelatedField(source='author.username', read_only=True) number_of_likes = serializers.SerializerMethodField() number_of_comments = serializers.SerializerMethodField() def get_number_of_likes(self, obj): return obj.likes.count() def get_number_of_comments(self, obj): return obj.comments.count() class Meta: model = Post fields = ['id', 'author', 'body', 'media', 'created_at', 'number_of_likes', 'number_of_comments'] read_only_fields = ['author', 'created_at', 'number_of_likes', 'number_of_comments'] class PostListCreateView(generics.ListCreateAPIView): queryset = Post.objects.all() serializer_class = PostSerializer permission_classes = [IsAuthenticatedOrReadOnly] … -
What is the best way to handle potentially large file uploads in django?

django StreamingHttpResponse to return large files

Django collectstatic not working in production after changing tailwind.config.js
I recently change my local tailwind.config.js to add the breakpoint rules. In local, to apply change i do ./manage.py tailwind start (im using django-tailwind) and then collectstatic and the change is applied. But when i push it to production and do the exact step i can't see the changes happen after i restart the server. I have tried running in incognito mode, changing from Chrome to Firefox, hard refresh my browser, purge my cache in Cloudfare. But i still didnt see the changes. What can it be? is there an option to force django to refresh staticfiles? I thought restarting the server was enough. -
What is the best and the fastest way to switch from Django to Node.js? [closed]
I want to switch from Django(Python) to Node.js(JavaScript), and I'm planning to do this within 2 months at maximum for some reason. So, what is the best way to achieve to this goal? I see two ways to do this: 1-To start a course(video, book and etc..). 2- To start coding and learn the differences at the way. I have tested both of them in previous week. Just started coding with js, and writing some algorithms, and it was cool. Also started the Eloquent JS book; it is good also, but long. I prefer reading rather than watching, in general. What method of learning should I use? -

Problem Description: I'm working on a Django project where I want to auto-play videos when they are at least 70% visible in the viewport and pause them when they fall below 70%. I've written the JavaScript using IntersectionObserver, and the logic works well on its own. However, I'm facing some issues when integrating it into my Django template. What I Have Tried: I have a Video model in Django where each video file is stored. In the template, I loop through the videos and apply the IntersectionObserver logic for auto-play and pause. The videos load and display correctly, but the auto-play behavior isn't consistent. Here’s my setup: models.py: class Video(models.Model): vidid=ShortUUIDField(length=10,max_length=100,prefix="video",alphabet="abcdefgh") title = models.CharField(max_length=100) description = models.TextField(blank=True) video_file = models.FileField(upload_to='videos/') uploaded_at = models.DateTimeField(auto_now_add=True) def __str__(self): return self.title views.py: def shorts_view(request,vidid): shorts1 = Video.objects.filter(vidid=vidid) shorts2 = Video.objects.all() context = { "shorts1":shorts1, "shorts2":shorts2, } return render(request,"videoshareing/shorts.html") shorts.html {%load static%} <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Lazy Load Shorts</title> <link href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/6.0.0-beta3/css/all.min.css" rel="stylesheet"> <style> /* Global Styles */ body, html { margin: 0; padding: 0; background-color: #181818; color: #fff; font-family: Arial, sans-serif; height: 100%; overflow-y: scroll; } .shorts-container { display: flex; flex-direction: column; } .video-container { position: relative; height: … -
Custom error messages in Django Rest Framework
I have a serializer: class CompanyProfileCreateSerializer(serializers.ModelSerializer): class Meta: model = CompanyProfile exclude = ["id", "company"] class CompanyCreateSerializer(serializers.ModelSerializer): company_profile = CompanyProfileCreateSerializer(required=True) password = serializers.CharField(write_only=True) class Meta: model = Company fields = ["id", "email", "password", "company_profile"] extra_kwargs = { "password": {"write_only": True, "style": {"input_type": "password"}} } def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) # Define custom error messages for all fields dynamically for field_name, field in self.fields.items(): field.error_messages.update({ "required": f"{field_name.replace('_', ' ').capitalize()} is required.", "null": f"{field_name.replace('_', ' ').capitalize()} cannot be null.", "invalid": f"Invalid value for {field_name.replace('_', ' ').capitalize()}." }) def create(self, validated_data): company_profile_data = validated_data.pop("company_profile") company = Company.objects.create(**validated_data, **company_profile_data) return company I added the __init__() method based on this answer to another question. But I am facing a problem. If I send the following request: { "email": "companytestregister1@gmail.com", "password": "password123", "company_profile": { "name": "Company Test Register1" } } the response I get is: { "field": "email", "detail": "user with this email already exists." } This is correct. The response is different from DRF's default error response because I am using custom exception handler. But the problem is that when I change the request to: { "password": "password123", "company_profile": { "name": "Company Test Register1" } } I still get the same error response. The … -
Django SESSION_EXPIRE_AT_BROWSER_CLOSE not working in Microsoft Edge
I am trying to log out users automatically when they close the browser or a tab. I have set: SESSION_EXPIRE_AT_BROWSER_CLOSE = True in my Django settings, and it works as expected in most browsers. However, it does not seem to work in Microsoft Edge. Is there a specific solution or workaround to make this functionality work in Edge? I also tried using beforeunload, but it logs out the user even when the browser is refreshed: $(document).ready(function() { $(window).on("beforeunload", function(e) { $.ajax({ url: "{% url 'logoutUser' %}", method: 'GET', }); }); }); -
Marking a Cookie as Partitioned in Django
This is my view: @ensure_csrf_cookie @require_http_methods(['GET']) def set_csrf_token(request): return JsonResponse({'message': 'Set CSRF cookie'}) I set this cookie in a Cross-Origin context so I also enable in my settings.py: CSRF_COOKIE_SAMESITE = "None" CSRF_COOKIE_SECURE = True However, my browser (FireFox and Chrome) both warn (require?) the use of Partitioned cookies; yet, Django appears to lack a setting for CSRF_COOKIE_PARTITIONED. So I ask what would be an elegant solution to setting my cookie as Partitioned? -
Django app under nginx and django gives a 502 sporadically on a large HTML page, other errors also
Before I did anything I would see a bad gateway on my deployed site or the error referenced here: Django/nginx/gunicorn giving this in deployment: GET https://.../ net::ERR_INCOMPLETE_CHUNKED_ENCODING 200 (OK) I changed a few things in nginx.conf and see less of the incomplete chunked error but still get the bad gateway. Viewing the nginx error.log I noticed errors that make no sense to me when I get the 502 bad gateway: 2024/09/16 12:34:24 [crit] 25088#0: *103 open() "/var/lib/nginx/tmp/proxy/4/01/0000000014" failed (13: Permission denied) while reading upstream, client: 10.75.0.152, server: 10.75.1.214, request: "GET /mainpage/nicfips/nicfipsguide/ HTTP/1.1", upstream: "http://unix:/run/apo_web.sock:/mainpage/nicfips/nicfipsguide/", host: "10.75.0.204:8080” I checked the folder where this referenced page exists and it is the same users as other links and and has what should be the correct chmod on it as well. As a test I took the HTML that is displayed on the page in question and it runs everytime so I know it is a timing issue of sorts, there is. just a REALLY long HTML page (I could break it up) but I am not sure why simple HTML is causing issues this day in age. The page does no database queries or anything. Guessing I need to edit a timing in … -
Django session creates new session key on every page refresh, causing duplicate carts
I am working on a Django app that uses user sessions to manage shopping carts. However, every time i refresh the page, a new session key is generated, which causes a new cart to be created. This results in multiple carts for the same user/session, which shouldn't happen. I'm try to understand why Django is creating a new session on every page refresh. On reload of /products multiple sessions are created in django backend [16/Sep/2024 17:11:31] "GET /api/products/ HTTP/1.1" 200 212 Session key: iedrvaus89536ly57pb242tnalwtx7vo [16/Sep/2024 17:11:31] "GET /api/carts/retrieve_cart/ HTTP/1.1" 200 107 [16/Sep/2024 17:11:31] "GET /api/products/ HTTP/1.1" 200 212 Session key: eipxdrmkf343fjtkchk7ads14ef1vccr [16/Sep/2024 17:11:31] "GET /api/carts/retrieve_cart/ HTTP/1.1" 200 107 If I click on add to cart I get two carts created: { "id": 77, "items": [ { "id": 66, "product": 1, "product_sku": "MNT-MST-MDL-HRV", "product_name": "Monthly Harvest Box", "product_price": 50.0, "quantity": 1 } ], "created_at": "2024-09-16T20:10:24.950541Z", "updated_at": "2024-09-16T20:10:24.950541Z" }, { "id": 78, "items": [], "created_at": "2024-09-16T20:10:25.006548Z", "updated_at": "2024-09-16T20:10:25.006548Z" } Here is ProductsPage.js import React, { useState, useEffect } from "react"; import './ProductsPage.css'; import Cart from './Cart'; import PictureGrid from "./PictureGrid"; const ProductsPage = () => { const [products, setProducts] = useState([]); const [cartItems, setCartItems] = useState([]); const [cart, setCart] = useState(null); // … -
