User roles are definitions of what users can do while using your applications. For example, when you are developing a marketplace for renting cars, you may need at least two user roles: hosts, who provide their cars, and users, who rent cars. Both of these user types will have different functions that they have at their disposal. Rolify is a Ruby gem that allows you to easily add and manage user roles in your application.
It can be integrated with other Ruby gems that you may need like authentication gems (devise, Authlogic, Clearance) and authorization gems that don’t provide role classes (CanCanCan, authority, Pundit).
You can install it as any other Ruby gem, and fortunately, it comes with a great README walk-through of the setup procedure and usage that you can follow along.
As it is an open source project, you can view its source code, learn how it’s built and also become a contributor to it.
