CommandError: The permission codename 'change_mymodel' clashes with a builtin permission for model 'myapp.MyModel'
django, django-south
Solution
Did you define custom permissions with names staring with "add_", "change_" or "delete_"?
If yes, then these permissions clash with the default permissions as documented here.
In this case: Remove your custom permissions and use the default ones or rename your custom permissions so they don't clash with the default ones.
