Install
=======

    $ gem source -a http://gems.github.com/
    $ sudo gem install mintdigital-has_roles

    # environment.rb
    config.gem 'mintdigital-has_roles', :lib => 'has_roles'

Example
=======

In an ActiveRecord class:

    has_roles :admin, :moderator

Then run:

    ./script/generate has_roles && rake db:migrate

Now your model has these instance methods:

    add_role(:moderator)    #=> true
    remove_role(:admin)     #=> true (doesn't have role)
    has_role?(:admin)       #=> false
    can_have_role?(:writer) #=> false

    # These are auto-generated based on your defined roles.
    # They just call has_role?(name)
    admin?      #=> false
    moderator?  #=> true
