Probably not explaining this clearly enough (I blame the distillery masters at Lagavulin), but: find_by_line_item fails - my_line_item is an instance of the class (an object) that does not have a 'line_item' attribute you indicated, it *is* a LineItem find_by_line_item_id works - rails infers the id attribute when you pass an object (my_line_item), and in this case you've provided enough information to tell rails which attribute to use... I suppose you could mod the logic for find to include your syntax... -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
