Define authentication filters and accessor helpers for a group of mappings. These methods are useful when you are working with multiple mappings that share some functionality. They are pretty much the same as the ones defined for normal mappings.
Example:
inside BlogsController (or any other controller, it doesn't matter which): devise_group :blogger, contains: [:user, :admin] Generated methods: authenticate_blogger! # Redirects unless user or admin are signed in blogger_signed_in? # Checks whether there is either a user or an admin signed in current_blogger # Currently signed in user or admin current_bloggers # Currently signed in user and admin Use: before_filter :authenticate_blogger! # Redirects unless either a user or an admin are authenticated before_filter ->{ authenticate_blogger! :admin } # Redirects to the admin login page current_blogger :user # Preferably returns a User if one is signed in
