ActiveRecord::Base subclasses in rails3 returns a string
Reported by johnf | June 24th, 2010 @ 09:04 AM
In rails 3 :ActiveRecord::Base.send(:subclasses) returns an array of strings rather than classes.
This means you see the error below. Adding a whole heap of constantize calls around the place seems to fix things
undefined method abstract_class?' for "Keyword":String
(NoMethodError)<br/>
