How to create admin user in django tests.py

Question

I'm trying to create an admin user as part of my tests.py to check on persmissions.

UPDATE: The tests.py is standard format that subclasses TestCase and the code below is called in the setUp() function.

I can create a normal user but not an admin user. If I try this:

    self.adminuser = User.objects.create_user('admin', '[email protected]', 'pass')
    self.adminuser.save()
    self.adminuser.is_staff = True
    self.adminuser.save()

OR self.adminuser = User.objects.create_superuser('admin', '[email protected]', 'pass') self.adminuser.save()

I get:

Warning: Data truncated for column 'name' at row 1

If I remove the is_staff line all is well (except I can't do my test!)

Do I have to load admin users as fixtures?

UserProfile is defined as follows:

class UserProfile(models.Model):

    user = models.ForeignKey(User, unique=True)
    organisation = models.ForeignKey(Organisation, null=True, blank=True)
    telephone = models.CharField(max_length=20, null=True, blank=True)

and full error traceback is:

The answer seems to be that you can't create an admin user in setUp but you can in any other function so if you want an admin user in testing, use a fixture!

Answer 1

I'd use the built-in create_superuser and log the user in before making any requests. The following should work:

from django.contrib.auth.models import User
from django.test.client import Client

# store the password to login later
password = 'mypassword' 

my_admin = User.objects.create_superuser('myuser', '[email protected]', password)

c = Client()

# You'll need to log him in before you can send requests through the client
c.login(username=my_admin.username, password=password)

# tests go here
