Working With Rails

Acts As Commentable

NOTES FROM DARL: * DO NOT set the commentable_type value of the comment. This is done automatically by the plugin.

Allows for comments to be added to multiple and different models.

Resources

Install * Run the following command:

script/plugin install http://juixe.com/svn/acts_as_commentable

• Create a new rails migration and add the following self.up and self.down methods

  def self.up create_table “comments”, :force => true do |t| t.column “title”, :string, :limit => 50, :default => ”” t.column “comment”, :text, :default => ”” t.column “created_at”, :datetime, :null => false t.column “commentable_id”, :integer, :default => 0, :null => false t.column “commentable_type”, :string, :limit => 15, :default => ””, :null => false t.column “user_id”, :integer, :default => 0, :null => false end end

  add_index "comments", ["user_id"], :name => "fk_comments_user"

  def self.down drop_table :comments end

Usage

• Make you ActiveRecord model act as commentable.

class Model < ActiveRecord::Base
    acts_as_commentable
end

• Add a comment to a model instance

model = Model.new
comment = Comment.new
comment.comment = 'Some comment'
model.comments << comment

• Each comment reference commentable object

model = Model.find(1)
model.comments.get(0).commtable  model
