Sorted indexes for Ohm

Setup

1. Include the Callbacks and Sorted modules in your model:

   include Ohm::Callbacks 
   include Ohm::Sorted
   

2. Add a sorted index to your model with the following line:

   sorted :ranking, group_by: :status
   

You will need to resave every model if they already exist.

Usage

To query the sorted index, use the sorted_find class method.

>> Post.sorted_find(:ranking, status: "draft")

This returns an Ohm::SortedSet, which is just a subclass of Ohm::BasicSet backed by a sorted set.

Requirements

This plugin works with Ohm versions higher than 0.1.3.
