Constants in models are initialized before fixtures are loaded?

Hi,

here's simplified code from the model: class Foo < AR::Base   FIRST = Foo.first.id end

The problem is that when testing I get well known error: "Called id for nil...". I guess that this constant is initialized before the fixtures are loaded.

Is there any way to fix it?

The constant is initialized when the class is loaded which is indeed
before the fixtures are. Does it have to be a constant or would

class Foo < ...    def self.some_function      #cache the value and return it    end end

be acceptable?
