Get values in real time in Django
I have made a sketch of how my project should look like. The user can communiticate with a virtual assistant over the web browser. The backend is Django. How to get values from the database in real time in Django? I've heard about Rest API, but I am not sure if that is the right thing to do. It is possible to use queries like website.com/?variable=value, but that is NOT what I want, because that slows down the time to "update" the user's screen and speakers. The frontend and backend is Django. The user should be able to communicate with Morpheus (there are other characters as well) when the "conversate" button is clicked. -
How can I display all fields from a Many-to-Many Model in Django Admin
I have the following Models: class ModelA(models.Model): some_field_A = models.CharField() some_other_field_A = models.CharField() class ModelB(models.Model): some_field_B = models.CharField() many_to_many_relation = models.ManyToManyField(ModelA) In admin.py I am using filter_horizontal to edit the ManyToManyField: class ModelB(admin.ModelAdmin): model = ModelB filter_horizontal = ('many_to_many_relation',) but it shows only some_field_A and I want it to show both fields from ModelA, because the entries in ModelA are unique depending on both fields and as you can see from the picture there are multiple entries with the same value (i.e. some_field_A = EUV) but they have different values for some_other_field_A: -
Celery 5.0.4 with Django 3.1.4 - OperationalError: Error 101 connecting to localhost:6379. Network is unreachable
I am having an issue with Django and Celery integration whereby it seems the settings for the RESULT_BACKEND and BROKER_URL keys are not being honored. I am running Django and Celery successfully in Docker with django-celery-beat without issue. Scheuduled tasks are running as expected. The issue I am having is when calling a @task function through a Django Signal. When this runs (triggered from Django Rest Framework); I get the following error: OperationalError: Error 101 connecting to localhost:6379. Network is unreachable. This would be expected because I dont run redis locally but within another container. Any ideas on why the configuration is not being used? I have confirmed that the environment variables are being loaded correctly and seen by both celery and Django. Compose File app-redis-prod: image: redis:alpine app-worker-prod: environment: - PLATFORM=prod - CERT_DIR=/run/certificates - DB_SSL_MODE=require - BROKER_URL=redis://rocx-redis-prod:6379 - RESULT_BACKEND=redis://rocx-redis-prod:6379 settings.py CELERY_BROKER_URL = os.environ.get('BROKER_URL', 'redis://localhost:6379') CELERY_RESULT_BACKEND = os.environ.get('RESULT_BACKEND', 'redis://localhost:6379') CELERY_ACCEPT_CONTENT = ['application/json'] CELERY_TASK_SERIALIZER = 'json' CELERY_RESULT_SERIALIZER = 'json' CELERY_TIMEZONE = 'UTC' CELERY_ENABLE_UTC = True celery.py app = Celery('MYAPP') app.config_from_object('django.conf:settings', namespace='CELERY') app.autodiscover_tasks() @app.task(bind=True) def debug_task(self): print(f"Request {self.request!r}") Any ideas would be greatly appreciated! -

Why can't I clear or change field on inline formset, but I can only add, after clicking submit button?
I am new to Django and I am trying to create a view that uses a form with fields, another form with an image and file field, and a third inline formset form with two fields that uploads an image and video with the option to add more after submit, all in the same view. The problem I am currently experiencing is that I am able to add videos to my inline formset, but I am not able to clear or change those fields and I would like to know if it is my view that is causing it. Thanks! View: def edit(request, id): all_objects = get_object_or_404(Profile, id=id) ProfileFormset = inlineformset_factory(Profile, MultipleFileUpload, fields=('image', 'video',), extra=1) if request.method == 'POST': form1 = EditProfile(request.POST or None, instance=all_objects) form2 = ProfileUpdateForm(request.POST, request.FILES, instance=all_objects) formset = ProfileFormset(request.POST, request.FILES, instance=all_objects) if form1.is_valid() and form2.is_valid(): form1.save() form2.save() formset.save() return HttpResponseRedirect(".") form1 = EditProfile(instance=all_objects) form2 = ProfileUpdateForm(instance=all_objects) formset = ProfileFormset(instance=all_objects) context = { 'form1': form1, 'form2': form2, 'formset': formset } return render(request, 'accounts/edit.html', context)``` -

How is the correct way to send a json serializer

How to use multi-tenant functionality in django
Im trying to create a project that should have multi-tenancy ability but i want it a bit customized. So here is my whole schema I want an organization to signup whenever someone lands on my main site, they will be given a landing page (handled in view, no worries about this) eg: www.test.com (this will be my public url) Lets say company puts the name "abc" in form and signs up for my site. Now I want to create a tenant like abc.test.com (tenant url) and also database (postgres) should have an organization table in public schema and an abc table in private schema This is my main goal of the project. Now I have achieved most of it. DB schemas are handled and everything is done by using django-tenants package by tomturner. What I cant achieve is the functionality to differenciate automatically between my public and private urls. Like if someone hits "www.test.com" should land on my main site if someone hits "abc.test.com" should land on my private urls. I know I have to write a middleware for this (which is given in django-tenants) but still im not able to achieve it. By the way im following https://github.com/django-tenants/django-tenants/tree/master/examples/tenant_multi_types/tenant_multi_types_tutorial this … -

Handling JWT Authentication for Soft Deleted Users in Django Rest Framework
I'm trying to make a username available once a user deletes their account. By default the username is unique meaning the username won't be available even after the account is soft deleted. This is, by default, the setup that comes with django out of the box. class CustomUser(AbstractUser): username = models.CharField( _('username'), max_length=150, unique=True, help_text=_('Required. 150 characters or fewer. Letters, digits and @/./+/-/_ only.'), validators=[UnicodeUsernameValidator()], error_messages={ 'unique': _("A user with that username already exists."), }, ) is_active = models.BooleanField( _('active'), default=True, help_text=_( 'Designates whether this user should be treated as active. ' 'Unselect this instead of deleting accounts.' ), ) is_active is used here to mark a model as deleted. So that I can be able to take advantage of UniqueConstraint and add a condition, I have to drop the uniqueness of the username. class CustomUser(AbstractUser): username = models.CharField( _('username'), max_length=150, unique=False, help_text=_('Required. 150 characters or fewer. Letters, digits and @/./+/-/_ only.'), validators=[UnicodeUsernameValidator()], error_messages={ 'unique': _("A user with that username already exists."), }, ) is_active = models.BooleanField( _('active'), default=True, help_text=_( 'Designates whether this user should be treated as active.

Blocked Set-Cookie in development environment DRF SessionAuthentication + React
I have a very specific question that I haven't found within the many questions regarding this topic. I have a DRF + React web application which I recently changed from Token Authentication to Session Authentication for server side expiration. In production this works great, upon login I receive two Set-Cookies, a session id and a csrftoken. However, in my development environment, the Set-Cookies are blocked as This Set-Cookie was blocked because it had the 'SameSite=Lax' attribute but came from a cross-site response which was not the repsonse to a top-level navigation.. I tried changing the SameSite setting to none, in which case Chrome requires secure cookies, which I don't think is possible in my dev environment. I tried disabling Cookies without SameSite must be secure in chrome://flags. Listing localhost in CSRF_TRUSTED_ORIGINS solves the CSRF, but then the login issue remains. Although I don't think this is relevant, a lot of solutions here mention to add {withCredentials: true} to the requests, this however does not solve my issue as I do receive the Set-Cookie headers, they're just blocked... -

Recreating a file-based POST request from Django-Rest-Framework test in curl
I have a test case using The test library from Django. In my test I have the following: class TestLoadCurve(TestCase): def setUp(self): self.client = Client() self.test_user = User.objects.create_user('test_user', 'a@b.com', 'test_user') self.client.login(username="test_user", password="test_user") def test_post_loadcurve_as_xlsx(self): response = self.client.post( reverse('loadcurves-list'), {'file': open("app/tests/loadcurve_files/loadcurve.xlsx", "rb"), "name": "testuploadloadcurve"}, ) self.assertEqual(response.status_code, status.HTTP_201_CREATED) And the (simplified) endpoint looks like this: class LoadCurveViewSet( mixins.CreateModelMixin, mixins.RetrieveModelMixin, mixins.ListModelMixin, viewsets.GenericViewSet ): ... def create(self, request, *args, **kwargs): up_file = request.FILES['file'] ... return Response(status.HTTP_201_CREATED) This test works. But I want to re-create the POST request that it makes using curl for some documentation. I have only made it so far: curl --user <myuser>:<mypass> -X POST -H --data-urlencode "payload={\"file\": $(cat app/tests/loadcurve_files/loadcurve.xlsx), \"name\": \"curlloadcurve\"}" http://localhost:5100/loadcurves/ Using the debugger I am able to stop the processing at the line up_file = request.FILES['file'], at which point I realize that both request.FILES and request.data are both totally empty. Am I not making the POST request correctly? I was following this answer Python version is 3.6.9 Django version is 3.1.3 -
Django - perform action on Profile while creating User
I was looking for solution for my problem here, but it didnt solve my problem. I want to create user's profile while their signing up.
