   This was a great tip but it would be nice to see how to use it with nested attributes in a form and also how to set the strong parameters for it in rails 4.

   So, do you have any advice for OO actions that work on data stored on the join table? For instance, if you added a field to Subscriptions called “expired” for folks that quit paying their subscription fee, how would you access and/or update the “expired” field?

   Obviously, you can pull the subscription through a call like *sub = Subscription.where(user: user, magazine: magazine)*, but i didn’t know if working directly on the Subscription model is considered the Rails Way of working CRUD on join tables.
