CSRF cookie error after Django 3.2 update (DRF with token authentication)
I was looking to update my app backend from Django 3.1.14 (working fine but no longer supported) to a newer version (I tried both 3.2 and 4.0), but after updating I started getting a CSRF cookie error. Forbidden (CSRF cookie not set.): /api-token-auth/ Does anybody by any chance know what's changed in Django in regard to CSRF, and how to avoid the errors? I was under the impression that CSRF is not enforced when using Django Rest Framework with token authentication. I tried anyway to remove the 'django.middleware.csrf.CsrfViewMiddleware' middleware, to add @csrf_exempt to all the views, deleted all existing tokens and logged out of Django admin, but to no avail. My DRF configuration in settings.py is as follows: INSTALLED_APPS = [ 'rest_framework', 'rest_framework.authtoken', ] REST_FRAMEWORK = { 'DEFAULT_AUTHENTICATION_CLASSES': ( 'rest_framework.authentication.TokenAuthentication', ), 'DEFAULT_PERMISSION_CLASSES': ( 'rest_framework.permissions.IsAuthenticated', ), } -
Using Django-Taggit in Django Rest Framework 3.13.1 with Django 4.0.2 with Error "Invalid json list" in Serializing Tags Model Attribute
Older solutions uses django-taggit-serializer which is now been deprecated and doesn't work with the version I have.

Django check if many-to-many relationship exists
I have a kind of social network in Django where people can send direct messages. Within all of those messages, I have a conversation field to show who the messages are between so that I can group the messages by person when displaying them to the user. I'm trying to figure out how I can search for if a conversation exists. In the print statements below in the view, I get back: <QuerySet [<Conversation: Sarah and Stephen>, <Conversation: Sarah and James>]> <QuerySet [<User: Sarah>, <User: Stephen>]> <QuerySet [<User: Sarah>, <User: James>]> In the view below, the sender is 'Sarah' and the receiver is 'James', so I'm trying to figure out how I can search for if a conversation between them already exists (through filter or something) by matching them with the kinds of QuerySet lists above so that if so, I can use that conversation and if not, I can create the conversation. I've tried many things but keep getting stuck. I'm pretty new to many-to-many relationships. The view def writemessage(request, id): profile = Profile.objects.get(id=id) context = { 'profile': profile, } conversations = Conversation.objects.all() print(conversations) for each in conversations: print(each.participants.all()) if request.method == 'POST': sender = request.user receiver = profile.user … -

How to catch an empty query exception with Django
I'm after an elegant and efficient approach. I am doing a query to a model that has a chance to return an empty queryset and if that happens I must do a query with other parameters that will work for sure. It would be really nice if I could put the query inside a simple try except but it doesn't catch like so. What's holding me back from using .exists() is that it feels like I'm doing the query to the database two times. One to check the existence and the other to really get the object. -

Best way to reuse code from an old data migration in a new data migration
A few months ago, I wrote a custom data migration that created some model objects. I wrote a function inside the migration file, create_data, and then for the migration operation, ran it using RunPython operations = [ migrations.RunPython(create_data) ] Now, we have another object we need to be automatically populated by migrations. I'd like to reuse my create_data function, but in a new migration. Problem is, I don't know if I can import it properly, or if importing from a previous migration is a bad idea. create_data = __import__('projects.project.migrations.0012_auto_20210331_2126').create_data This doesn't work, but anyways I think there are issues importing from files that start with numbers that make this weird. The other idea I have is to copy paste this function into one of my normal django apps where reusable code lives, then I could import it as usual and use in future migrations without issue as well. The downside is that the code is still copy pasted once. How should I reuse my old code from this older migration in a new migration? Is there a nice way to import it, or should I just copy paste it to a better place and never put logic in migration files … -
How to modify all databases when overriding DiscoverRunner setup_databases with parallel

add help text for OneToOneField

Adding Data from Bootstrap Cards as Django Objects Using Checkboxes
This is kind of a complicated question, but: I am using Django. User enters data on one template and then using logic in my view and an API call, the next page is rendered which displays multiple bootstrap cards, each containing data from that API call present in that first view. On top of each bootstrap card holding the data is a checkbox. I would like to have the user be able to check/uncheck any bootstrap card to add the data from those cards as a new object (NewNFT from my models.py). In an attempt to make it less complicated, I will just share my html, which shows how each card is formatted with the text box/data from the API call and then I will also share my model for the object that is being created. Is anyone able to explain how to add each of these 'cards' (really data from each card) as a new object for my model? I can't figure out the view.py logic to make that happen. For some reason it's not letting me display, but of course there would be a form around the card data as well as a submit button. And the data … -
Does Zappa support Djangos recently added async functionality?
I'm starting to learn Django's new native async support: https://docs.djangoproject.com/en/4.0/topics/async/ Is it supported by Zappa? I've tried creating a basic async view but when I deploy it using Zappa the view just runs in normal sync mode. I'm aware that Zappa has it's own async functionality (wish I knew about it earlier), but I'd prefer to use the Django async. -
Many to Many table of MYSQL database in django
I connected my Django project to an existing MySQL database. Migration worked well and I can see the new Django-generated tables in the MySQL database. I have some many-to-many relationship tables in the MySQL database, without primary keys, since it is not necessary for MySQL. The Django documentation specifically states that every model needs a primary key and that Django might auto-generate a primary key column. When running inspectdb, I don't see that Django added anything to my database. An example table "countries" the columns: country_id and country_name many-to-many table "country_neighbors" the columns: country_id and neighbor_country_id(which is a country_id in the countries table) Question: Can I just use my database as is and use the inspectdb-generated foreign keys in the many-to-many model as I did when I only worked directly with the mysql database? many thanks! -

Issues with NGINX / SSL Certificate when running docker-compose with NGINX, Django & Acme companion
