STI sub classes not loaded until parent is
Reported by Ian Ownbey | May 2nd, 2008 @ 01:23 AM
When using STI, a Uninitialised Constant error is thrown when calling subclasses (Doc in following example) before parent class is called (container in following example).
Ex:
class Container < ActiveRecord::Base
end
class Doc < Container
end
Doc
#=> uninitialized constant Doc
Container
#=> Okay
Doc
#=> Okay

ooooo all the STI are in the same file as the model. This could be creating the problem.

That will definitely be a problem. If they are both in container.rb, how can the dependencies mechanism know that if you hit const_missing for Doc you need to look in container.rb?

Auto-loading only works when each class is in its own file. If you want to keep all the files in one, you can always force the load with require_dependency 'container' some where.
