TypeError: Field 'id' expected a number but got <django.contrib.auth.models.AnonymousUser object at 0x7f5e95756920>

Question

first time I ask on the website.

I was testing a Django Restframework app. The is to check an unauthenticated user that wants to create a review. I got this error: TypeError: Field 'id' expected a number but got <django.contrib.auth.models.AnonymousUser object at 0x7f5e95756920>.

this is the class test: class ReviewTestCase(APITestCase):

def setUp(self):
    self.user = User.objects.create_user(
        username="example", password="Password@123")
    self.token = Token.objects.get(user__username=self.user)
    self.client.credentials(HTTP_AUTHORIZATION='Token ' + self.token.key)

    self.stream = models.StreamPlatform.objects.create(
        name="Netflix",
        about="#1 Platform",
        website="https://www.netflix.com"
    )
    self.watchlist = models.WatchList.objects.create(
        platform=self.stream, title="Example Movie",
        storyline="Example Movie",
        active=True
    )
    self.watchlist2 = models.WatchList.objects.create(platform=self.stream, title="Example Movie",
                                                      storyline="Example Movie", active=True)
    self.review = models.Review.objects.create(review_user=self.user, rating=5, description="Great Movie",
                                               watchlist=self.watchlist2, active=True)

    data = {

        "rating": 5,
        "description": "Great Movie!",
        "watchlist": self.watchlist,
        "active": True
    }

    response = self.client.post(
        reverse('reviewcreate', args=(self.watchlist.id,)), data)
    self.assertEqual(response.status_code, status.HTTP_201_CREATED)
    self.assertEqual(models.Review.objects.count(), 2)

    response = self.client.post(
        reverse('reviewcreate', args=(self.watchlist.id,)), data)
    self.assertEqual(response.status_code, status.HTTP_400_BAD_REQUEST)

Answer 1

In data items, you are passing an object, and you have to pasa an id. Change this:

review_user: self.user.id

Answer 2

Thanks to everyone, I found the mistake. In fact the problem was not in the func in the tests.py but in the view, where I misspelled: permission_classes = [IsAuthenticated] with: permission_clasees = [IsAuthenticated] So everything is fine now. Thanks again to all of you
