Images do not appear on a page even though they are already in a DB (Django)
I try to learn how to deploy my django project. I have a form in which user can upload his image. The image is a content for ImageField of a Recipe model. Uploading process is working as expected but when I try to display these pictures on the page they just dont appear.

404: NOT_FOUND error on Vercel - Django deployment
I deployed a Django project on Vercel and it shows the deployment is successful. However, when I try to open the website, it shows the error: 404: NOT_FOUND Code: NOT_FOUND ID: lhr1:lhr1::6n29s-1732227821846-0cc9eddbb440 My Django project can be found in the following link: https://github.com/RailgunGLM/railgunglm-com I tried solving the problem by, as some solutions on stackoverflow suggested, inserting a vercel.json file and a build.sh file, adding the line app = application at the very end of wsgi.py, including .vercel.app in my ALLOWED_HOSTS in setting.py, and lastly, installed whitenoise. However, none of them seems to work. The application works normally in my local machine, but I'm not sure whether I made a mistake in one of these files. I would be really appreciated if there is a solution to fix this problem. -
Changing the session key to a different user model field
I have my own user model. Django derives the session key from the primary key in this model. However, I wish to use a different field as the primary key / session key. The problem with changing the primary key is that it will break existing logged in sessions since the Django session middleware code tries to convert the session key to the type of the primary key defined in the model. I wish to change from username to a uuid. I thought I could work around this by having different auth backends since the session stores the backend but this type conversion occurs before Django calls the get_user method in my custom backends. Is there a way to uses a new field as the primary key? -
Constraint to forbid NaN in postgres numeric columns using Django ORM
Postgresql allows NaN values in numeric columns according to its documentation here. When defining Postgres tables using Django ORM, a DecimalField is translated to numeric column in Postgres. Even if you define the column as bellow: from django.db import models # You can insert NaN to this column without any issue numeric_field = models.DecimalField(max_digits=32, decimal_places=8, blank=False, null=False) Is there a way to use Python/Django syntax to forbid NaN values in this scenario? The Postgres native solution is to probably use some kind of constraint. But is that possible using Django syntax? -
DRF serializer missing fields after validation
I have a simple DRF serializer: class CustomerFeatureSerializer(serializers.Serializer): """ Serializer for a customer feature. """ feature_id = serializers.CharField() feature_value = serializers.SerializerMethodField() feature_type = serializers.CharField() name = serializers.CharField() def get_feature_value(self, obj): """ Return the feature_value of the feature. """ return obj.get("feature_value", None) the feature_value field is a method field since it can be either a boolean, an integer, or a string value (so for now I just kept it as a method field to fetch the value). I am using this to serialize some objects that I am hand-generating (they do not correspond 1:1 with a model) but for some reason after validation the name and feature_value fields are just completely disappearing. for feature in toggleable_features: display = { "feature_id": feature.internal_name, "name": feature.name, "feature_value": profile.feature_value(feature) if profile.has_feature(feature.internal_name, use_cache=False) else False, "feature_type": feature.type, } features.append(display) print(display) print(features) serializer = CustomerFeatureSerializer(data=features, many=True) print(serializer.initial_data) serializer.is_valid(raise_exception=True) print(serializer.validated_data) return Response(serializer.validated_data) and the print statements output: {'feature_id': 'feat-id', 'name': 'feat name', 'feature_value': True, 'feature_type': 'boolean'} [{'feature_id': 'feat-id', 'name': 'feat name', 'feature_value': True, 'feature_type': 'boolean'}] [{'feature_id': 'feat-id', 'name': 'feat name', 'feature_value': True, 'feature_type': 'boolean'}] [OrderedDict([('feature_id', 'feat-id'), ('feature_type', 'boolean'), ('name', 'feat name')])] the value is just gone.

Django Test Environment Runs Twice and Fails When Using if not IS_PRODUCTION and INJECT_FAKE_DATA
Description: I'm encountering a strange issue in my Django test environment. When running my test suite, the environment appears to initialize twice, causing a specific test to pass the first time and fail on the second run. The problem seems to be related to the following conditional statement in my settings.py file: if not IS_PRODUCTION and INJECT_FAKE_DATA: # Code for injecting fake data Environment Details: Django version: 5.1.1 Python version: 3.12.1 Test Framework: pytest with pytest-django Database: MongoDB for test What Happens: When I run my tests, the environment is reloaded twice (as evidenced by logs). On the first initialization, everything works as expected, and the test passes. On the second run, the same test fails due to the environment not behaving as intended.

Celery picks up new tasks, but all old are stuck in PENDING
In a nutshell: I'm able to run new celery tasks but the old ones are stuck with PENDING states. Celery run command: celery -A config.celery_app worker --pool=solo --loglevel=info Environment: Celery 5.4.0 redis-server 7.4.1 on WSL (Windows Linux) The celery and Django app runs on windows and the redis-server in WSL. I ran celery a couple of times and everything was good, but now I constantly see some old tasks as "PENDING" state when I read their state in Django with AsyncState(task_id). Purging the queue with celery -A config.celery_app purge didn't make anything either. I visited a couple of threads on this, but none seem to be dealing with my precise problem. (I'm still able to execute new tasks) I wonder if it's not a problem with running on WSL or something like this, because I'm also unable to see the task queues from the app or CLI: celery inspect active_queues gives kombu.exceptions.OperationalError: [WinError 10061] No connection could be made because the target machine actively refused it and doing: i = app.control.inspect() scheduled = i.scheduled() shows no tasks Project is built with django-cookiecutter and Celery task was basically defined as: @app.task def my_task(**kwargs): return my_function(**kwargs) -

Use existing page for error 404/505 in Wagail
I am using the most recent version of Wagtail, 6.3.1 at this time. I want to use a specific page for an error 404 and error 500 so I can have it in line of the rest of website.

Django: Objects that live throughout server lifetime
I have some data in csv format that I need to load into the application once and then reuse it throughout the lifetime of the application, which is across multiple requests. How can I do that? An obvious method for me is to have a module that will load the data and then expose it. However, I don't like modules doing a lot of work, because then imports lead to unexpected side effects. I would like to do that one-time work in a predictable, deterministic fashion, not because someone imported a module. Does Django provide some hooks for globals? Some kind of Application/Service class where I could do that work and then access the data in the requests? -

Difference between Apple Sign-In Token Request: /auth/token vs /auth/keys
I am working on a Flutter + Django REST Framework application and implementing Apple Sign-In functionality. When Iam tried to manually obtain the user's access_token, I followed the flow where needed to generate a client_secret on the backend (it was a JWT built using values like KEY_ID, TEAM_ID, CLIENT_ID, and CLIENT_SECRET from APPLE DEVELOPER account). I would then send the authorization_code (received from flutter), client_secret(genereted by developer on backend), and other details to https://appleid.apple.com/auth/token to get the access_token. However, when integrating the same Apple Sign-In functionality using the drf-social-oauth2 library for Django, I noticed that I no longer need to use all those keys and secrets (like KEY_ID, TEAM_ID, CLIENT_SECRET etc.). Instead, it only requires the CLIENT_ID and identity_token that I receive from the Flutter app, and it sends a request to https://appleid.apple.com/auth/keys, which returns the access_token without needing the authorization_code from Flutter. So, what is the difference between these approaches? In both cases, I get an access_token (although access_tokens have different expiration times), but the only thing is that in one case, I don't need all those keys, and in the other, I do. -

Django - Failed Login Redirecting To Different Page
I am new to Django and I am trying to use the authentication system. I have managed to get it working using the default Auth URLS.

I have managed to display the form, and when a user enters correct details, the login is successful. Unfortunately when the user enters wrong information it is currently redirecting me to the login url (accounts/login) I have been trying to rectify this, but I either break the auth or it redirects, I cannot seem to find a solution.

I'm debugging sitemap generation, and finally have the following snippet: items=Event.objects.all() for limit in (1000, 10000, 20000): events=items[:limit] print(f'{limit=}') start=time() for obj in events.values('id', 'slug', 'date_updated'): s='/events/{0[slug]}_{0[id]}_{0[date_updated]}/'.format(obj) print(f' Time spent: {time()-start:.2f}') start=time() for obj in events.only('slug', 'date_updated'): s=f'/events/{obj.slug}_{obj.pk}_{obj.date_updated}/' print(f' Time spent: {time()-start:.2f}') And I have the following output: limit=1000 Time spent: 0.26 Time spent: 9.80 limit=10000 Time spent: 0.66 Time spent: 85.09 limit=20000 Time spent: 1.18 Time spent: 177.20 I see in the doc that QuerySet.values() is recommended for few fields and when you don't need the complete Model behaviour, which is indeed the case here. But is the overhead of creating Model instances (and whatever more there is under the hood) indeed SO huge? Or it's something about my setup and (mis)configuration. When it's doing models, I see both python and mysql processes consume CPU. And it's inexplicable, because same query when I run it in mysql client takes half a second. -
Get currenty logged in user in Django/Angular
I am creating a Django / Angular project but I am having an issue. In normal django applications without frontend framework we can just do request.user and we can get the iformation needed. I already created the api endpoints to my User model but is there a way to directly find the user Id to make a call like this: getUserById(userId: number): Observable<User> { const url = `${this.baseUrl}users/${userId}/`; return this.http.get<User>(url); } Or do I need to set up a different serializer like this for example: class CurrentUserView(APIView): permission_classes = [IsAuthenticated] def get(self, request): user = request.user # Get the current logged-in user serializer = UserSerializer(user) return Response(serializer.data) make a call to this endpoint and then with the data from here access the rest of the endpoints? Also right now I havent set up an Authentication mechanism. Maybe in the future if I do I wont be needing an endpoint like this? Thanks in advance -
Django HTTPS with nginx as reverse proxy. Issues with CSRF tokens
I developed a Django application which runs inside a docker container. Outside the container, a natively runnign nginx does the reverse proxy-ing of the requests that django application. Django runs via WSGI with gunicorn. General setup: I use a HTTP sever on port 80 which only serves a redirect to HTTPS on Port 443. No data is actually served on that port. Port 443 is setup for HTTP/2 with SSL encryption Path /static is served by nginx to supply static django data. Path / is configured as proxy to the django instance: location / { proxy_set_header Host $http_host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; proxy_pass http://127.0.0.1:8000; # This is the port the docker container with my django listens to } Django is configured with the following options: # Production only settings SESSION_COOKIE_SECURE = True CSRF_COOKIE_SECURE = True SECURE_SSL_REDIRECT = False I set the SECURE_SSL_REDIRECT to false, as I have a server internal healthcheck that accesses the django application on http://localhost:8000 and checks its status. As there is not HTTPS on that route, a forced SSL redirect would break that check. I rely on the strict configuration of nginx that an outside access can never occur via HTTP …
