mongoid_order

An easy way to make mongoid documentation order-able.

This class is extracted from benedikt’s great gem github.com/benedikt/mongoid-tree with some modifications. Thanks to benedikt!

Requirements

To install mongoid_order, simply add it to your Gemfile:

gem 'mongoid_order'

In order to get the latest development version of mongoid_order:

gem 'mongoid_order', :git => 'https://github.com/arkxu/mongoid_order.git'

And then:

bundle install

Add the include Mongoid::Orderable in the model:

class Node
  include Mongoid::Document
  include Mongoid::Orderable
end

This will add a position field to your document and provide additional utility methods:

node.move_up
node.move_down
node.move_to_top
node.move_to_bottom
node.move_above(other)
node.move_below(other)

node.at_top?
node.at_bottom?
