valid causes this exception.
To change that:
class Node < ActiveRecord::Base def self.instance_method_already_implemented?(method_name) return true if method_name == 'changed' return true if method_name == 'changed?' super end end
But note, that this will influence the functionality of ActiveRecord (without changed? the API can’t distinguish, if the model was changed or is valid etc.).
