Can't have Fixtures with ID 0?

Is it not possible to load fixtures with ID of 0? Is there a way to
force it?

TIA

Just don’t specify an ID at all.

Wouldn't it just auto increment though?

The ID of a fixture record should actually be irrelevant. IMO you should
NEVER use ID as a basis for any part of your tests. There simply isn't a
need and it leads to fragile tests almost every time. For instance

User.find(1) can be users(:something_useful)

if assigns(:user) == 34 can be if assigns(:user) == users(:some_user).id

In almost every case its clearer without the ID. In Rails 2 you don't
even need to specify ID's anymore and its about time.
