Acts As Commentable with Reply¶ ↑

Provides a single Comment model that can be attached to any model(s) within your app. It creates Comment and CommentReply models and handles the plumbing between those models and any models that you declare to be commentable models. The replies are limited to one-level nesting. If you need no nesting then check out acts_as_commentable. If you need deeper nesting then checkout acts_as_commentable_with_threading.

The advantage of this gem over acts_as_commentable_with_threading is that it does not use the nested set model and this leads to faster writes. Check this Wikipedia article for further reading on the nested set model.

Installation :¶ ↑

Add the following line to your Gemfile

Rails 4¶ ↑

gem 'acts_as_commentable_with_reply'

Generator¶ ↑

Rails 4¶ ↑

rails g comment

Then migrate your database to add the comments and comment_replies models:

rake db:migrate

Usage¶ ↑

Make the desired ActiveRecord model act as commentable:

class Post < ActiveRecord::Base
  acts_as_commentable
end

Add a comment to a model instance by adding the following to the controller:

commentable = Post.create
comment = commentable.comments.create
comment.title = "First comment."
comment.comment = "This is the first comment."
comment.save

Add a reply to a comment instance by adding the following to the controller:

comment = Comment.find x # Any other way of obtaining a comment instance
reply = comment.comment_replies.create :reply => "This is the first reply."

Fetch comments for the commentable model by adding the following to the view:

commentable = Post.find(1)
comments = commentable.comments.recent.limit(10).all

Fetch replies for a comment instance by adding the following to the controller/view:

comment = Comment.find x # Any other way of obtaining a comment instance
replies = CommentReply.find_comment_replies comment

You can also add different types of comments to a model:

class Todo < ActiveRecord::Base
  acts_as_commentable :public, :private
end

To fetch the different types of comments for this model:

public_comments = Todo.find(1).public_comments
private_comments = Todo.find(1).private_comments

By default, ‘acts_as_commentable` will assume you are using a `Comment` model. To change this, or change any other join options, pass in an options hash:

class Todo < ActiveRecord::Base
  acts_as_commentable class_name: 'MyComment'
end

This also works in conjunction with comment types:

class Todo < ActiveRecord::Base
  acts_as_commentable :public, :private, { class_name: 'MyComment' }
end
