orderable

User customizeable ordering for active records.

How to use

Add a field to keep track of the ordering position to your model:

class AddOrderablePositionToPosition < ActiveRecord::Migration
  def self.up
    add_column :positions, :order_position, :integer
  end

  def self.down
    remove_column :positions, :order_position
  end
end

Include Orderable in your model

class Position < ActiveRecord::Base
  include Orderable

Specify the column to use for ordering:

orderable_field_is :order_position

Now get the records back in order:

Position.in_order.all

Or update the ordering:

Position.update_order([0, 3, 2, 1])

Contributing to orderable

  • Check out the latest master to make sure the feature hasn’t been implemented or the bug hasn’t been fixed yet

  • Check out the issue tracker to make sure someone already hasn’t requested it and/or contributed it

  • 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.
