Hi
Please help me in understanding the :source option of has_one/has_many through association. The Rails api explanation makes very little sense to me
"Specifies the source association name used by has_many :through queries. Only use it if the name cannot be inferred from the association. has_many :subscribers, :through => :subscriptions will look for either :subscribers or :subscriber on Subscription, unless a :source is given. "
Thanks.
