mintdigital-has_roles

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
