Where is user.admin? defined in rails-devise-pundit starter app?

Question

I used RailsApps rails-composer to create a rails-devise-pundit starter application. I am still a little new to ruby on rails and newer to devise, pundit and rails 4.

Answer 1

Roles are defined in the app/models/User.rb file (the User model).

class User < ActiveRecord::Base
  .
  .
  .
  enum role: [:user, :vip, :admin]
  after_initialize :set_default_role, :if => :new_record?

  def set_default_role
    self.role ||= :user
  end

end

The application uses the ActiveRecord enum method to manage roles. ActiveRecord provides convenient methods to query the role attribute:

user.admin! # sets the role to "admin"
user.admin? # => true
user.role  # => "admin"

See documentation for ActiveRecord::Enum for details. The ActiveRecord enum method is new in Rails 4.1.

I've updated the README for the rails-devise-pundit application to include this information. It's also covered in my Rails Pundit Tutorial.

It is an attribute of the User model. Same as first_name or last_name, there is a field called admin which is a boolean.
