User create Dynamic Role base

Hi! So my app uses CanCanCan and Devise for working with users. Now the app needs to have a feature where users can create role. How can I approach this new task.

Example:
Admin(User) can create Roles with a permission list (can and can't with on/off boolean) without redeploying the app.

Check out Rolify. It can handle pretty much anything you want to do with roles and permissions.
