How to test nested Serializers in Django Rest?
I have a ToDo App Django project, and so there are Task and TaskList models which are linked with a ManyToMany relation. Inside my TaskSerializer, I have defined a nested TaskListSerializer which handles the reverse relation of a task's tasklists. Everything is going well in real world, and the serialization and deserialization is ok. This is what you should put request when updating a task (as json): { "title": "hello", "tasklists": [ {"pk": "b84d3375-0e09-4dd1-9809-f92d29d6aa36"}, {"pk": "b84d3375-0e09-4dd1-9809-f92d29d6aa36"} ] } But inside the Tests, I want to test this serializer and, when I'm sending the put request the tasklists field is not sent to the view! This is the test request: path = self.task.get_absolute_api_url() data = { "title": "hello", "tasklists": [ {"pk": "b84d3375-0e09-4dd1-9809-f92d29d6aa36"}, {"pk": "b84d3375-0e09-4dd1-9809-f92d29d6aa36"} ] } self.client.put(path, data) But there is no tasklists field inside the validated_data and initial_data of view.(the title field is sent and validated) I guess that the Renderer and json_encoder have the problem with this type of data. so how should the correct request data be inside a nested serializer test? In General, How to test a Nested Serializer! -
How to handle forward slash in API call
I know this goes against all of the rules, but I have a database that has a primary key in the format of /. Ex. 12345/A. I'm using Django Rest Framework and can't seem to make the API call to retrieve this record. The Django admin changes this to 12345_2FA in the URL, but this doesn't work for the API call. Thanks! -
Django Password Reset Form Not Showing When Using DRF, Works from Website
I'm facing an issue with my Django application involving the password reset functionality. When the password reset link is sent via the standard Django website flow, everything works as expected: the user receives an email with a link, and upon clicking it, they are taken to a page with a form to reset their password. However, when the reset link is sent through a Django Rest Framework (DRF) API (triggered from a Flutter app), the user still receives the email with a link, but the page that opens does not show the password reset form. The rest of the HTML content on the page renders correctly, but the form itself is missing. Here's the relevant part of my CustomPasswordResetConfirmView in Django: class CustomPasswordResetConfirmView(PasswordResetConfirmView): form_class = SetPasswordForm success_url = reverse_lazy('users:password_reset_complete') template_name = 'users/password_reset_confirm.html' @method_decorator(sensitive_post_parameters('new_password1', 'new_password2')) @method_decorator(csrf_protect) def dispatch(self, *args, **kwargs): return super().dispatch(*args, **kwargs) def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) context['form'] = self.form_class(user=self.request.user) return context And the template users/password_reset_confirm.html is as follows: <main class="mt-5" > <div class="container dark-grey-text mt-5"> <div class="content-section"> <form method="POST"> {% csrf_token %} <fieldset class="form-group"> <legend class="border-bottom mb-4">Reset Password</legend> {{ form|crispy }} </fieldset> <div class="form-group"> <button class="btn btn-outline-info" type="submit">Reset Password</button> </div> </form> </div> </div> </main> I am not sure … -
conditional constraints for django model
I have database model like this ActionType = ( (1,"PostBack"), (2,"Uri"), ) class RichMenu(BaseModel): key = m.CharField(max_length=64,unique=True) action_type = m.IntegerField(choices=ActionType,default=1) url = m.CharField(max_length=255,blank=True,null=True) name = m.CharField(max_length=255,blank=True,null=True) Now I would like to make constraint like this, When action_type is 1, url should be null and name should not be null When action_type is 2, name should be null and url should not be null Is it possible to make conditional constraints for this case? -
Nginx can't load static files, did I set wrong path?
I tried setting up nginx with docker on my django project. I checked the volume exists on docker container. And I do have access to my swagger path, but staticfiles does not load. What else can I attempt? Thanks... For example, as settings.py has set the path: # Static files STATIC_URL = "/static/" STATICFILES_DIRS = [ os.path.join(BASE_DIR, "static"), ] STATIC_ROOT = os.path.join(BASE_DIR, "staticfiles") and here is nginx/nginx.conf, may see locaiotn in http: events { worker_connections 1024; } http { upstream django { server web:8000; } server { server_name localhost; access_log off; listen 80; location /static/ { alias /app/staticfiles/; } location / { proxy_pass http://django; proxy_set_header Host $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; } } } And finally, docker-compose script: version: '3.8' services: web: build: . command: gunicorn core.wsgi:application --bind 0.0.0.0:8000 --timeout 120 --workers 3 volumes: - .:/app - static_volume:/app/staticfiles ports: - "8000:8000" depends_on: - redis nginx: image: nginx:latest volumes: - ./nginx/nginx.conf:/etc/nginx/nginx.conf:ro - static_volume:/app/staticfiles ports: - "80:80" depends_on: - web ...... volumes: static_volume: -

Best way to import models from a bunch of different django projects
Basically I have a project that has a bunch of microservices and a number of databases across them. What I want is to create another service that I can run different scripts on that make some changes to the prod db. For example if there was a bug that messed up some records, I'd have to go in to the prod db and fix those records. What would be the best way to import all these models? I want to be able to do something like service_a.db.ModelA service_b.db.ModelB etc Or is there a package I can use to do this already instead of trying to build my own? -

Adding tags to identify notes in a django website?
I am currently working on a django project where you can upload course materials, have a personal calendar with notes and a to-do list. I am working on the notes and a personal feature I would like to add is I would either like to be able to attach the notes to a class, or I would like to be able to add identifying tags that would group the notes. Maybe even make it so that when they "enroll" in a paticular class, it automatically creates a folder for that class for them to add notes to. Could anyone shed some light on possible ways I could accomplish this? So far, I only have the ability to create notes, edit and delete them. -

How should mysql.connector be shared correctly with threads in Django applications?
This concerns a potential solution to my earlier question in which I was getting commands out of sync; you can't run this command now after wrapping mysql cursors in __enter__ and __exit__. I have read elsewhere that Django does not spawn new threads to handle multiple requests, but rather multiple Django processes would normally be spawned in order to achieve parallelism. Despite this advice, I began printing Thread.ident and Thread.native_id and noticed that they were changing. Based on this, I speculatively wrote something like: def db_connect (): t = threading.current_thread() if not hasattr (t, 'db_connection'): print (f"New MyDBConnectionClass for {t.ident}~{t.native_id}") t.db_connection = MyDBConnectionClass () return t.db_connection.get_cursor () # This object has a __exit__ which closes the cursor along with class MyDBConnectionClass (): def __del__(self): t = threading.current_thread() print (f"MyDBConnectionClass deleted for {t.ident}~{t.native_id}") the view handlers' usage of the cursors is unchanged: with db_connect() as db: results = db.all (query, args) So far this seems to have fixed the commands out of sync error (and the exit code 245 crash mentioned in the original question). MyDBConnectionClass.__delete__ is not being called, but various instances are created for a few different ident values. My current hypothesis is that there is some sort of … -
