callbacks

There are several callbacks on following actions:

• update
• save
• delete (will be destroy in upcomming release)
• initialize

To use these callbacks just use the "rails" way:

class Page < GollumRails::Page

    after_save :update_something

    def update_something
      do_stuff
    end

end

You can also use whole classes, which respond to these callbacks:

class Callbacks

  def self.after_save(object)
    object.do_something
  end

end

class Page < GollumRails::Page

    after_save Callbacks

end

where object is the current instance of Page.

There are two types of callbacks:

• before_* .
• after_* .

Each of the above named actions has these types of callbacks.
