Give this man a cigar! That's exactly what's going on. class WeatherObservation < ActiveRecord::Base belongs_to :start_time, :class_name => 'TimeDimension', :foreign_key => 'start_time_id' belongs_to :end_time, :class_name => 'TimeDimension', :foreign_key => 'end_time_id' belongs_to :weather_station ... end The ActiveRecord::Associations::ClassMethods doc has a nice section on "auto generated methods" -- I didn't notice that it's the argument to :belongs_to that defines the method name and not :foreign_key, i.e. it generates: WeatherObservation#start_time rather than: WeatherObservation#start_time_id Good catch -- thanks. -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
