Acts As Commentable (now with comment threads(TM)!!! -- kidding on the (TM))
Allows for threaded comments to be added to multiple and different models. Drop-in compatible for acts_as_commentable (however requiring a database schema change)
The 2.x version of this gem is for Rails 4 and later versions only. For the Rails 3.x compatible version of this gem, please use version 1.2.0.
This gem depends on CollectiveIdea's Awesome Nested Set gem. It is installed if not already present when you install this gem.
You can find the gem on GitHub at collectiveidea/awesome_nested_set
In your Gemfile, add:
To install from scratch:
rails generate acts_as_commentable_with_threading_migration
This will generate the migration script necessary for the table
To upgrade to acts_as_commentable_with_threading from the old acts_as_commentable:
rails generate acts_as_commentable_upgrade_migration
This will generate the necessary migration to upgrade your comments table to work with acts_as_commentable_with_threading
If the generators fail, you can just as easily create the migrations by hand.
See the templates in the generators under
class Article < ActiveRecord::Base acts_as_commentable end
Add a comment to a model instance, for example an Article:
@article = Article.find(params[:id]) @user_who_commented = @current_user @comment = Comment.build_from( @article, @user_who_commented.id, "Hey guys this is my comment!" )
To make a newly created comment into a child/reply of another comment:

@all_comments = @article.comment_threads
To retrieve only the root comments without their child comments:
@root_comments = @article.root_comments
