Unable to submit a form with Django (Using UserCreationForm & ModelForm)
I've been trying to create a method to upload a profile picture for a user at the time of registration.

How to LIMIT number of different choices in my model that user can save? - Python Django
I have model UserDraft. Inside that model I have pick_id with different choices represented in numbers when u go into Django Admin. I want each choice to be limited to max 5 times for each user to be picked. For example in this code I want to have user1, 1, hero1, user1, 1, hero2, etc....Also i would love to restrict that you cant pick same hero twice. models.py from django.db import models from users.models import User from heroes.models import Hero from django.core.exceptions import ValidationError class UserDrafts(models.Model): FIRST = "1" SECOND = '2' THIRD = '3' PICK_ID = [ (FIRST, 1), (SECOND, 2), (THIRD, 3), ] user_id = models.ForeignKey(User, on_delete=models.CASCADE, related_name="user_id") pick_id = models.CharField(max_length=20, choices=PICK_ID) hero_id = models.ForeignKey(Hero, on_delete=models.CASCADE) def save(self, *args, **kwargs): if self.__class__.objects.filter(user_id=self.user_id).count() >= 5: raise ValidationError('Maximum five picks are allowed per user') return super().save(*args, **kwargs) def __str__(self): return self.user_id.username class Meta: verbose_name = "UserDraft" verbose_name_plural = "UserDrafts" This save method that I used only limits user to pick more then 5 times. But I also want to be able to restrict choices for each choice to be picked 5 times per 1 user...So maximum number of picks will be 15. 5 pick_id`s will be 1(FIRST), 5 will be … -
Django REST framework: How to use multiple PKs in URL with class based views/serializer
I have two models (examples): class Container(models.Model): name = models.CharField(max_length=100) class ObjInContainer(models.Model): Container = models.ForeignKey(Container, on_delete=models.CASCADE) A Container can have N number of ObjInContainer. I'm trying to write a REST API to do two things: First: See all ObjInContainer from a single Container: # urls.py url(r'^container/(?P<container_id>\d+)/objects_in_container/$', ContainerObjectsListAPIView.as_view(), name='container_objects_list'), # views.py class ContainerObjectsListAPIView(ListAPIView): queryset = ObjInContainer.objects.all() queryset = queryset.prefetch_related('container') serializer_class = ContainerObjectsListAPIView # serializer.py class ContainerObjectsListAPIView(ModelSerializer): container = SerializerMethodField() class Meta: model = ObjInContainer fields = [ 'id', 'container', ] def get_container(self, obj): return str(obj.container.name) But this lists all ObjInContainer from ALL Container. How do I tell REST Framework that the Container it needs to get the ObjInContainer from is the one in the URL from <container_id> ? I suppose in views.py where I declare queryset = ObjInContainer.objects.all(), should really be queryset = ObjInContainer.objects.filter(container_id=container_id), but how do I access the <container_id> part of the URL in the view class? Any my second issue is how to detail a single ObjInContainer, by using two different IDs in the URL? # urls.py url(r'^container/(?P<container_id>\d+)/objects_in_container/(?P<obj_in_container_id>\d+)/$', ContainerObjDetailAPIView.as_view(), name='container_object_detail'), # views.py class ContainerObjDetailAPIView(RetrieveAPIView): queryset = ObjInContainer.objects.all() serializer_class = ContainerObjDetailSerializer # serializer.py class ContainerObjDetailSerializer(ModelSerializer): container = SerializerMethodField() class Meta: model = ObjInContainer fields = [ 'id', 'container', ] … -

django on AWS with multiple settings file
Well, I had one setting file before and it was working perfectly both in local and AWS of course with both the database configuration in one setting file. When ever I use to push my code on AWS I would comment my local db configuration and then push. So for sure, that's annoying. I can't comment and uncomment constantly both the database configuration in one file. Therefore, I decided to have 2 setting files. one for the local and the other for AWS. Once I pulled the code into AWS server and run migrations python manage.py migrate --settings=settings.staging It worked and migrated. By the way, this is the setting file which resides my RDS configuration.

Django Rest Framework ViewSet testing with JWT tokens
I'm trying to test my Django Rest Framework (DRF) views with a JWT token created by Firebase. I'm using a package called drf-firebase-auth to implement the actual authentication backend. Here're my current DRF settings: REST_FRAMEWORK = { "DEFAULT_PAGINATION_CLASS": "rest_framework.pagination.PageNumberPagination", "PAGE_SIZE": 10, "DEFAULT_PERMISSION_CLASSES": [ "rest_framework.permissions.IsAuthenticated", ], "DEFAULT_AUTHENTICATION_CLASSES": [ "rest_framework.authentication.SessionAuthentication", "drf_firebase_auth.authentication.FirebaseAuthentication", ], } When I use Postman to query the development API with the proper JWT token, everything seems to work fine. I get a response with a 200 code etc. and the payload contains what I know is in my development database. However, when I start writing tests for my views, I start getting 403 and 500 codes. Here's an example where I'm using DRF's RequestsClient client to do the actual testing: class UserViewsetTestCase(APITestCase): def setUp(self): self.token = get_firebase_id_token_v2() self.client = RequestsClient() self.base_url = "http://127.0.0.1:8000/api/users/" self.client.headers.update({"Authorization": f"JWT {self.token}"}) def test_user(self): response = self.client.get(self.base_url) self.assertEqual(response.status_code, 200) This leads to an assertion error noting that 500 != 200: ====================================================================== FAIL: test_user (organizations.tests.test_views.UserViewsetTestCase) ---------------------------------------------------------------------- Traceback (most recent call last): File "/Path/to/project/organizations/tests/test_views.py", line 32, in test_user self.assertEqual(response.status_code, 200) AssertionError: 500 != 200 Note that the utility function get_firebase_id_token_v2 returns the Firebase based JWT token for me on the server: def get_firebase_id_token_v2(): api_key = settings.FIREBASE_PUBLIC_API_KEY url … -
Django authentication not working for browser
I am trying to use django's inbuilt authentication system for my application. I'm able to authenticate a user during login but, for the following requests request.user.is_authenticated is coming as False login view: user_name = request_body['username'] password = request_body['password'] user = authenticate(username=user_name, password=password) if user is not None: login(request, user) request.session.set_expiry(86940) I've written a decorator to check authentication, the code is: from django.http import HttpResponse def authenticate_request(f): def check(request): if request.user.is_authenticated: #coming as false even after authenication is done return f(request) else: return HttpResponse(status=401) return check What am I missing while authenticating the request? -
