A simple MongoMapper plugin to make adding comments to your models easy
v1.2 is a mongomapper 0.9.0 update to support the new plugin system if you are using mongomapper 0.8.x please use version 1.1 of the gem
Install the gem
gem install mm-commentable
Or add it to your Gemfile
gem 'mm-commentable'
Then add the commentable plugin to you MongoMapper::Document
class Post
include MongoMapper::Document
plugin MongoMapper::Plugins::Commentable
def on_add_comment(comment)
do something when a comment is added...
end
end
You must implement the #on_add_comment callback! - however it can be an empty implementation It is called when a valid comment is added to the commentable item with #add_comment!
@post = Post.create @commentor = User.create @post.add_comment!("great post..", @user) @post.comments_count # => 1 @posts.comments # => [<Comment>]
The commentor association is polymorphic, so any class will probably work, I expect the commentor would normally be an instance of class <User>, but it could be a <Person> or an <Account> and it will still work

Fork the project
-
Start a feature/bugfix branch
-
Commit and push until you are happy with your contribution
-
Make sure to add tests for it. This is important so I don’t break it in a future version unintentionally.

Please try not to mess with the Rakefile, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.
