A bookmarkable model can be any ActiveRecord class so you can use the acts_as_bookmarkable to bookmark other users in a friends list, or bookmark posts in a favorites list, etc. And following the Web 2.0 trends, bookmarks themselves can act as taggable so that you can label bookmarks with tags. You need to install the acts_as_taggable plugin separately, or you can remove one line in the bookmark.rb file to disable tags for bookmarks.

Usage

• Make your ActiveRecord model act as bookmarkable.

  class Model < ActiveRecord::Base

    acts_as_bookmarkable
  

  end

• Add a bookmark to a model instance

  model = Model.new bookmark = Bookmark.new(:title => ‘bmark title’) model.bookmarks << bookmark

• Each bookmark references the bookmarkable object

  model = Model.find(1) model.bookmarks.get(0).bookmarkable == model
