运行测试用例时，Django的user_logged_in信号不起作用

Question

I have this signal:

@receiver(user_logged_in)
def on_user_login(sender, request, **kwargs):
    if request.user.is_superuser:

It all works when running the app. But when testing, this piece of code fails:

self.client.force_login(...)

The test fails with:

AttributeError: HttpRequest object has no attribute user

If I remove the signal, that test case runs just fine.

I have Django 1.10

Answer 1

In my test I was testing one of the admin views. I wanted to login the user first before doing this change. What I did not realize was that I really wanted to test just the admin view, not logging in.

So instead of using client for testing, I used RequestFactory and passed the user in it. No logging in necessary.

The original error was due to the fact that client in django tests does not add the user to the request.
