I want to use composite primary keys in django but I can't find a solution, I tried it in different ways, even trying to make an alter in the table but it won't let me, I want to use it based on this model class Contiene(models.Model): id_boleto = models.OneToOneField("Boleto", primary_key=True, on_delete=models.CASCADE) boleto_cdg = models.CharField(default='', max_length=50) # Asegúrate de que este campo sea opcional num_orden = models.ForeignKey("OrdenCompra", on_delete=models.CASCADE) cantidad_total = models.IntegerField() def generate_random_code(self): numbers = ''.join(random.choices(string.digits, k=12)) # Genera 12 números aleatorios letters = ''.join(random.choices(string.ascii_uppercase, k=3)) # Genera 3 letras aleatorias return numbers + letters def save(self, *args, **kwargs): # Si no se ha proporcionado un boleto_cdg, entonces genera uno automáticamente if not self.boleto_cdg: self.boleto_cdg = self.generate_random_code() # Llamar al método save de la superclase para guardar el objeto super(Contiene, self).save(*args, **kwargs) def __str__(self): return f"{self.id_boleto}{self.num_orden}{self.cantidad_total}{self.boleto_cdg}"` Where num_orden and id_boleto would become composite pk, please help!!!

django field local for every user
How can I create a field that is different for every user. For example if we have an instance of a Comment model and there is a field that is different for every user that tells if user has liked that comment. So when I map through the objects i can just check if a user has liked it. Something like a local field for every user. -

How to filter objects based on a field in parent model

Both parent models are the same. -

Mocking signals function in unit test
I'm using Django version 4.2.6. I have a file, signals.py, that includes a pre-save handler for my entity: def do_stuff(sender, instance, **kwargs): ... stuff... pre_save.connect(do_stuff, sender=MyEntity) ... so that when an instance of MyEntity is either created or updated, the do_stuff() function is executed. How do I mock do_stuff() in unit tests? I have a number of tests that create and update MyEntity instances, so do_stuff() is being called during the execution of the unit test. My implementation of do_stuff() is making a call to an external source amongst other functionality, so I want to mock it when the unit test runs. I have tried declaring the following a part of my unit test: @mock.patch("application.package.signals.do_stuff", autospec=True,) ... but when I execute the test, I can see that do_stuff() is still being executed. -

How to change time input format in Django Admin?
The Django docs describe the use of TIME_INPUT_FORMATS, and say that the formats are described using the Python datetime module syntax. But in Django Admin 4.2 none of the directives - I'm using %H, %M, %I, %p - are making any difference. Instead, both 12-hour and 24-hour time inputs are accepted, with and without leading zeros. How do I gain control over the format, preferably without altering admin templates? Here are the other relevant settings: settings.py LANGUAGE_CODE = 'en-us' TIME_ZONE = 'America/Denver' USE_TZ = True USE_I18N = False There's the input_formats argument for DateTimeField, but that includes date formats, and I need just the time formats separately (for a Django Admin detail view of an object that has a datetime field). There's also another question about display of times that looks interesting, but I'm concerned now with time input. -

How to filter a queryset to show unique items of certain category in a database using django?

Can't create Django Custom User from Django admin page
I've created a custom user model named User that inherits from AbstractUser to add two additional fields for two-factor authentication (otp_base32 and otp_auth_url).

Can I use drf-spectacular's GET_MOCK_REQUEST setting to fake a request when testing my API with Swagger UI?
I'm using drf-spectacular to document the API endpoints of a Django / DRF project, mainly with the @extend_schema decorator and it works nicely for the Swagger UI. What I would like to do is to "alter the behaviour" of some of the API endpoints so that when they are called from Swagger UI, we end up with a faked response of some sort (instead of regularly processing the request through the code). So I'm trying things with the GET_MOCK_REQUEST setting, but I can't get anywhere : its function seems to be called for every detected endpoint during api schema generation (but I can't see any changes in the yaml schema file, is this revealing ?). when playing with the supposed "altered endpoints" in Swagger UI, this function is not called. I'm probably missing something here, I might have misunderstood what GET_MOCK_REQUEST is meant for... Some help would be appreciated. -
Django AppRegistryNotReady when running Unittests from vscode
My UnitTest test cases in a Django project run fine when running them directly from the Django utility (python manage.py test). However, when trying to run them from VSCode's test explorer, I get django.core.exceptions.AppRegistryNotReady: Apps aren't loaded yet.. I found several similar questions that were already answered here on SO, but none of the solutions seem to work. Here's what I tried: import my classes (e.g. models) within the SetUpTestData method and the actual test methods of the test class, rather than at the top of the file. This seemed to help a bit, in the sense that the tests now do show up in the test explorer (previously they didn't), but I still get an error when running them. set the DJANGO_SETINGS_MODULE environment variable at the top of the file containing the test class: import os os.environ.setdefault("DJANGO_SETTINGS_MODULE", "my_project.settings") add a .env file to my root directory, containing DJANGO_SETINGS_MODULE = my_project.settings add a configuration with purpose debug-test to launch.json: "configurations": [ { "name": "Django test", "type": "python", "request": "launch", "program": "${workspaceFolder}\\manage.py", "args": [ "test" ], "purpose": ["debug-test"], "django": true, "justMyCode": true } ] remove tests.py from my app folder, as my tests are stored in a separate folder (and apparently … -

uploaded images not alwasy visible on production azure environment
I have dockerized a django applicaton and deployed with NGINX on Azure.I also executed the command: manage.py collectstatic for copying the static files to the directories that are served by the file server. So I created on the azure environment a App service and I pushed everything to the docker containers. And everything is working fine. But a user has the ability to upload an image. And now comes the strange part. After some time, the uploaded image is not displayed in the app. And sometimes it is displayed in the app For example this image"with url: .azurewebsites.net/media/media/photos/animals/Grey_Wolf_klein_formaat_232396120.jpg is displayed. But this image with url: azurewebsites.net/media/media/photos/animals/335946586_Gestreepte_jakhals_klein_formaat.jpg is not displayed and gives a 404: 404 Not Found nginx/1.25.3 So I will show you partly the the settings.py of django: STATIC_URL = '/static/' MEDIA_URL = '/media/' STATIC_DIRS = [ (BASE_DIR, 'static') ] STATICFILES_DIRS = [BASE_DIR / 'static'] STATIC_ROOT = BASE_DIR / 'staticfiles/' MEDIA_ROOT = BASE_DIR / 'media' # Default primary key field type # https://docs.djangoproject.com/en/4.1/ref/settings/#default-auto-field DEFAULT_AUTO_FIELD = 'django.db.models.BigAutoField' and the NGINX.conf file looks: upstream DierenWelzijn { server web:8000; } server { listen 80; server_name https://dockerdierenwelzijn.azurewebsites.net; location / { proxy_pass http://DierenWelzijn; proxy_set_header Host $http_host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; client_max_body_size 10M; proxy_redirect off; } location … -

Dual Django stack on same database
We have just finished migrating our very old Django 1.6 (with South)/ Python 2 app to a new well-maintained OS running a well-maintained version of PostgreSQL There were several attempts to upgrade the Django app code, but it's so old it relies on libraries that are no longer supported or have a new version with a radically changed APIs. We finally settled to copying the entire virtual environment and run old code on old libraries. It actually works just fine internally. However, third party APIs have moved on and don't support old libraries anymore. Not that they were working on the old server. So we would like to create a new Django 5 / Python 3 stack that would cover the following Social login Modern Django Rest framework A new frontend with a modern framework, eventually Now, running two nginx server {} or location {} with separate gunicorns doesn't scare me but I'm wondering: can the two stacks use the same database ? can I interact with sessions using one stack and expect the other to follow ? how can I evolve the model properly on both stacks ? -
