Allows to connect any two ActiveRecord objects through a double polymorphic association object - A Link (how surprising) We use this plugin to generate week links between objects allowing better flexibility. This plugin used the Acts_as_commentable plugin as a base.

• Run the following command:

script/plugin install

class AddLinksTable < ActiveRecord::Migration
def self.up create_table "links", :force => true do |t| t.column "created_at", :datetime, :null => false t.column "linkable_id", :integer, :default => 0, :null => false t.column "linkable_type", :string, :limit => 15, :default => "", :null => false t.column "target_id", :integer, :default => 0, :null => false t.column "target_type", :string, :limit => 15, :default => "", :null => false t.column "member_id", :integer, :default => 0, :null => false end

      add_index "links", ["member_id"], :name => "fk_links_member"
    end

    def self.down
      drop_table :links
    end

  def self.down
  end
end
