Let's say you have

class Chili < ActiveRecord::Base
  has_many :beans
end

class Bean < ActiveRecord::Base; end

class Pinto < Bean; end

Now, let's say you have one chili record that's associated with one pinto (it's a sad chili). If you do this

>> mychili.beans
= []

Where the beans at?!

The problem is that in development, Rails doesn't preload any classes, but the association proxy won't actually look for subclasses of Bean when building it's query unless those subclasses have been loaded, so you don't get any beans. This doesn't happen in prod where all model classes are pre-loaded, but it was source of some confusion for me this morning.

A dumb workaround:

>> Pinto
>> mychili.beans
= [#<pinto id:="" 1="">]
