As I am sure you know the 'find_by*' methods are all dynamic. They are based on the field/column name, not on the type of object the column is supposed to reference (if any). AR will do the magic of finding the ID value if you pass an object to the method but apparently it will not be "magic enough" to let you remove the '_id' suffix from the field/column name in your 'find_by*' method name. It would be nice if the Rails guys made a little change so we could do what you wanted to do here, though. ;)
