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

TIA

Wouldn’t it just auto increment though?

Just don’t specify an ID at all.

Just try it and find out for yourself.

Why would you want all fixtures with id=0 anyway?

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.
