Multiple user roles for Rails

Have you ever wondered how to handle multiple user roles?, if so you probably have been doing with a column on the user, but soon enough you will encounter with the problem of having specific columns for each role, which causes a lot of NULL columns and becomes hard to scale.

rails g acts_as_user:install

The generator will install in initializer which describes all the ActsAsUser configuration options, so we recommend you take a look at it. When you are done you are ready to start your user model:
