Django "Table already exists" on testing
you should use python manage.py migrate app_name rather than python manage.py migrate.Because you had used it before
I've tried to solve the following issue: 
I'm running python manage.py test to test my application. 
After creating a new test_app database, I'm getting 

DatabaseError: (1050, "Table 'auth_group' already exists") 

I haven't installed South (it's not on the INSTALLED_APPS list), how do I solve this?
