It's easy to get this error when you start designing tests.

If this is the case in the admin background to return the account, and then enter the corresponding page can be, the specific reasons do not know

Feels like getting a user failed

Update:

Replaced the Django Abstractuser in the user model you wrote

However I set the name to be empty, so return nonstring

Modification Method:

In the __STR__ function, set the return value to Abstractuser inside the username.
