I have a class called "Foo" that looks like this: class Foo < ActiveRecord::Base belongs_to othermodel end and a class "Bar" that looks like this: class Bar < Foo belongs_to thirdmodel end When i try to serialize bar with : bar.first.to_json(:include => :othermodel), it fails in production mode. Strangely it works in the development environment. I digged around and found that the bar.first.class.reflections.keys only includes "thirdmodel" and not "othermodel" in production mode. I can''t explain that, in rails 2 and in the development environment it works prefect. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
