The CanCan gem offers a straight forward and flexible way to define what a user can and cannot do.

CanCan is an authorization library for Ruby on Rails which restricts what resources a given user is allowed to access.

CanCan uses a model to define the abilities of a user. Inside the class you declare what a user can and cannot do by using the “can” method. From your controllers you use the "can?" method to test the current user's authorization.
