This is true, I've encountered this as well. You do get basic database
level validation of your queries which will catch the big sillies, but
I think the validation happens using the manipulators. Just trying it
now I've gotten some mileage with this:
>>> from django.models.auth import users
>>> manipulator = users.AddManipulator()
>>> manipulator.get_validation_errors(dict(username="mtt",
first_name="Michael", last_name="Twomey", email="mtt"))
{'date_joined_date': ['This field is required.'],
'date_joined_time': ['This field is required.'],
'email': ['Enter a valid e-mail address.'],
'last_login_date': ['This field is required.'],
'last_login_time': ['This field is required.'],
'password': ['This field is required.'],
'username': ['User with this username already exists.']}
What would be nice is some kind of validate flag for save or the class
constructor which raised an exception with this info in it. This would
make life a little easier for scripting.
Another thing missing is logic to construct the slugs, they currently
come from the admin javascript AFAIK.
cheers,
