Add likes to your Mongoid models
Posted by Cesidio Di Landa on 08 November 2012
We needed a way to add likes to stories for Minstrels. We started looking for gems that provide this functionality and we found tombell/mongoid-voteable, that does a little more by providing a voting system to mongoid models. So we decided to fork this gem and focus only on likes. Today we gave it back to the open source community.
add the gem to your
Mongoid::Likeable module to the models you want to like.
You can like a story by simply using the
like method on the model.
There is also a method to check if a user liked a model.
Likes are stored in a field called
likes, so you can sort models by like count.
Note: if your users are not stored in a Mongo collection or the ID field is
_id, you can still pass the ID in as the second parameter instead.
