Django unit testing - authenticated user check in model method
I am using Django 3.2 I am trying to test a model that checks if a user is authenticated. The model code looks something like this: class Foo(Model): def do_something(user, **kwargs): if user.is_authenticated(): do_one_thing(user, **kwargs) else: do_another_thing(**kwargs) My test code looks something like this: from model_bakery import baker from django.contrib.auth import authenticate, get_user_model User = get_user_model() class FooModelTest(TestCase): def setUp(self): self.user1 = baker.make(User, username='testuser_1', password='testexample1', email='user1@example.com', is_active = True, is_superuser=False) baker.make(User, username='testuser_2', password='testexample2', email='admin@example.com', is_active = True, is_superuser=True) self.unauthorised_user = authenticate(username='testuser_2', password='wrongone') def test_user(self): self.assertTrue(self.user1.is_validated) # why is this true? - I haven't "logged in" yet? self.assertFalse(self.unauthorised.is_validated) # Barfs here since authenticate returned a None So, How am I to mock an unauthenticated user, for testing purposes? - since it appears that the is_authenticated property is read only? -

Vue - Optimal way of receiving notifications from back-end
I'm adding backend-sent notifications to my Vue 3 app. My Django backend generates notifications and saves them to the user inbox; where they can be accessed and read at any time. I'm trying to decide which way is best for the front-end to receive such notifications. Basically, I'm torn between two options: use polling; something like a setInterval of 20 seconds that simply makes a REST call to get the most recent notifications for the user open a websocket; the server pushes a message each time there's a new notification I'm leaning a little more towards the websocket option; however, I am concerned with: complexity: having to manage re-connections and all the things that can go wrong with a WS performance: I am predicting peaks of 200-300 users at a time; is having that many open WS connection a possible concern? Weighing these factors, which one would be the better choice for my needs? And how would you mitigate the drawbacks of the chosen approach? -
