Make BooleanField required in Django Rest Framework

I've got a model with a boolean field that I'd like to deserialize with the Django rest framework and I want the serializer to complain when a field is missing in the post request. Yet, it doesn't. It silently interprets a missing boolean as False. ``` class UserProfile(models.Model): """ Message between two users """ user = models.OneToOneField(User, verbose_name="django authentication user", related_name='user_profile') newsletter = models.BooleanField(null=False) research = models.BooleanField(null=False) ``` The model is created with a Serialiser like this: ``` class UserProfileSerializer(serializers.ModelSerializer): research = BooleanField(source='research', required=True) newsletter = BooleanField(source='newsletter', required=True) class Meta: model = UserProfile fields = ('research', 'newsletter') ``` In my view I'm also creating a user, so I have some manual steps: ``` def post(self, request, format=None): userprofile_serializer = UserProfileSerializer(data=request.DATA) reg_serializer = RegistrationSerializer(data=request.DATA) phone_serializer = PhoneSerializer(data=request.DATA) errors = {} if userprofile_serializer.is_valid() and reg_serializer.is_valid() and phone_serializer.is_valid(): user = reg_serializer.save() data = reg_serializer.data user_profile = userprofile_serializer.object user_profile.user = user userprofile_serializer.save() return Response(data, status=status.HTTP_201_CREATED) errors.update(reg_serializer.errors) # ... return Response(errors, status=status.HTTP_400_BAD_REQUEST) ``` However, the following test case fails, because the rest framework doesn't complain about the missing param but instead inserts a False in from_native ``` def test_error_missing_flag(self): data = {'username': "test", 'password': "123test", 'email': 'test@me.com', 'newsletter': 'true', 'uuid': self.uuid} response = self.client.post(reverse('app_register'), data) # should complain that 'research' is not found self.assertTrue('research' in response.data) ``` If I replace my 'research' field with an Integer field that the serializer fails as expected. Any ideas?
