When I do ```python -m unittest`` inside of my users app, I get this error:
TypeError: argument of type 'ConnectionHandler' is not iterable
I was customizing my User model in django and I wanted to make a test for it. I already did the migrations and the custom User model works good (I did with a new database), so I expected to run the test successfully. Here is my test code:
from django.test import TestCase
from django.contrib.auth import get_user_model
# Create your tests here.
class UsersManagersTests(TestCase):
def test_create_user(self):
User = get_user_model()
user = User.objects.create_user(email='[email protected]', password='foo')
self.assertEqual(user.email, '[email protected]')
self.assertTrue(user.is_active)
self.assertFalse(user.is_staff)
self.assertFalse(user.is_superuser)
try:
# username is None for the AbstractUser option
# username does not exist for the AbstractBaseUser option
self.assertIsNone(user.username)
except AttributeError:
pass
with self.assertRaises(TypeError):
User.objects.create_user()
with self.assertRaises(TypeError):
User.objects.create_user(email='')
with self.assertRaises(ValueError):
User.objects.create_user(email='', password="foo")
def test_create_superuser(self):
User = get_user_model()
admin_user = User.objects.create_superuser('[email protected]', 'foo')
self.assertEqual(admin_user.email, '[email protected]')
self.assertTrue(admin_user.is_active)
self.assertTrue(admin_user.is_staff)
self.assertTrue(admin_user.is_superuser)
try:
# username is None for the AbstractUser option
# username does not exist for the AbstractBaseUser option
self.assertIsNone(admin_user.username)
except AttributeError:
pass
with self.assertRaises(ValueError):
User.objects.create_superuser(
email='[email protected]', password='foo', is_superuser=False)

if not email:

email = self.normalize_email(email)
user = self.model(email=email, **extra_fields)
user.set_password(password)
user.save()
return user

Why does the test fail?
