Testing Django Admin Action (redirecting/auth issue) - django

Question

I'm trying to write tests for an Admin action in the change_list view. I referred to this question but couldn't get the test to work. Here's my code and issue:
class StatusChangeTestCase(TestCase):
"""
Test case for batch changing 'status' to 'Show' or 'Hide'
"""
def setUp(self):
self.categories = factories.CategoryFactory.create_batch(5)
def test_status_hide(self):
"""
Test changing all Category instances to 'Hide'
"""
# Set Queryset to be hidden
to_be_hidden = models.Category.objects.values_list('pk', flat=True)
# Set POST data to be passed to changelist url
data = {
'action': 'change_to_hide',
'_selected_action': to_be_hidden
}
# Set change_url
change_url = self.reverse('admin:product_category_changelist')
# POST data to change_url
response = self.post(change_url, data, follow=True)
self.assertEqual(
models.Category.objects.filter(status='show').count(), 0
)
def tearDown(self):
models.Category.objects.all().delete()
I tried using print to see what the response was and this is what I got:
<HttpResponseRedirect status_code=302, "text/html; charset=utf-8", url="/admin/login/?next=/admin/product/category/">
It seems like it needs my login credentials - I tried to create a user in setUp() and log in as per Django docs on testing but it didn't seem to work.
Any help would be appreciated!

I found the solution - I wasn't instantiating Django's Client() class when I created a superuser, so whenever I logged in - it didn't persist in my subsequent requests. The correct code should look like this.
def test_status_hide(self):
"""
Test changing all Category instances to 'Hide'
"""
# Create user
user = User.objects.create_superuser(
username='new_user', email='test#example.com', password='password',
)
# Log in
self.client = Client()
self.client.login(username='new_user', password='password')
# Set Queryset to be hidden
to_be_hidden = models.Category.objects.values_list('pk', flat=True)
# Set POST data to be passed to changelist url
data = {
'action': 'change_to_hide',
'_selected_action': to_be_hidden
}
# Set change_url
change_url = self.reverse('admin:product_category_changelist')
# POST data to change_url
response = self.client.post(change_url, data, follow=True)
self.assertEqual(
models.Category.objects.filter(status='show').count(), 0
)
