Inherited views in Rails 3.1 - instance variables

How can an inherited view 开发者_如何学Ctemplate know what the (main) instance variable name is? Is there:

• some built-in way to detect them using some magic, or;
• we roll our own (with the controller name is the only method I can think of right now), or;
• use some generic name, or;
• ???

Rolling my own right now, but if the wheel's already been invented...

Ok after some reading and experimentation, I found out that it has the same helpers as inherited_resource_views

• collection to get the collection (eg. index action)
• resource to get the resource (eg. show action)

And the resource(s) are still available as instance variables (eg. @user in UsersController)
