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).


class Container < ActiveRecord::Base

class Doc < Container

#=> uninitialized constant Doc
#=> Okay
#=> Okay

    Works fine for me. Where have you put these classes?

    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.
