Rails - Nov 2010 - Bug when serializing to_xml when :foreign_key is named like association

Think of the following models:

class User < ActiveRecord::Base
  has_many :created_entities, :class_name => "Entity", :foreign_key
=>
"created_by"
end

class Entity < ActiveRecord::Base
  belongs_to :created_by, :class_name => "User", :foreign_key =>
"created_by"
end

There is also a created_by integer field in the Entity migration.
Everything seems to work fine with these model (fetching the
association and so on), but when I try to serialize
Entity.to_xml :include => :created_by (or include something other the
model has as association) it fails (NoMethodError: undefined method
`macro'' for nil:NilClass).
For full trace see:
http://stackoverflow.com/questions/4217923/nomethoderror-when-serializing-to-xml

But as soon as I rename the association in the Entity model to:
belongs_to :creator, :class_name => "User", :foreign_key =>
"created_by"
the serialization to_xml start to work again.

Im using Rails 3.0.1. Can someone reproduce that?

Guess what ... solved in Rails 3.0.3 :-)

I''d say you''re skating on thin ice: what''s
some_entity.created_by
supposed to return: the foreign_key or an instance of User?
