Greetings, I have a problem with attr_accessor and create seemingly being at odds with each other in my environment. Here is the setup: A simple class representing a US State (say, Maine for example): class State < ActiveRecord::Base attr_accessor(:name, :code) end In an IRB session, I type the following and receive the response...

...9;, :foreign_key => ''friend_id'' has_and_belongs_to_many :friends_of, :join_table => ''friends'', :class_name => ''User'', :foreign_key => ''user_id'', :association_foreign_key => ''friend_id'' attr_accessor :new_password attr_accessor :friends attr_accessor :friends_of ... end But when I use user.friends or user.friends_of they always return nil even after I entered some data in the db manually. There are no errors in the logfile... Any ideas? thanks Frank
