Permalink

Instalation

gem install permalink

Usage

Add the method call permalink to your model. Your model should have a permalink attribute.

class Page < ActiveRecord::Base
  permalink :title
end

You can specify the permalink field:

class page < ActiveRecord::Base
  permalink :title, :to => :title_permalink
end

If you don't want to use permalink, you can call 'some text'.to_permalink string method and manage the permalink process by yourself.

Permalinks are not unique by default. permalink overrides to_param as following:

def to_param
  "#{id}-#{permalink}"
end

You can define the to_param format:

class Page < ActiveRecord::Base
  permalink :title, :to_param => %w(id permalink page)
end

The above settings will generate something link 100-some-title-page. By overriding to_param method you don't have to change a thing on your app routes.

If you want to generate unique permalink, use the :unique option:

class Page < ActiveRecord::Base
  permalink :title, :unique => true, :to_param => :permalink
end

The permalink is generated using ActiveSupport::Multibyte::Chars class; this means that characters will properly replaced from áéíó to aeio, for instance.

The permalink is created when before_validation callback is evaluated. This plugin also tries to generate a permalink when before_save callback is evaluated and the instance has no permalink set.

You can force the permalink generation by setting the :force option.

class Page < ActiveRecord::Base
  permalink :title, :force => true
end
