has n, :through micro issue

Reported by comboy | November 11th, 2008 @ 04:16 AM

When somebody defines a has n, :through association and he doesn't define has many relation to the :through model, he got some strange errer about calling method name on nil object which may be confusing.

Maybe it's a good idea to let this bad coder know what may be wrong. It's probably not even worth creating a patch but something like

 if options[:through] && !relationships.keys.include?(options[:through])
   raise ArgumentError, "Relation '#{options[:through]}' not found.", caller

in associations.rb in method "has" may do the job.
