ActiveRecord::OrderByIds
ActiveRecord scope methods for ordering by an explicit list of values.
Installation
Add this line to your application's Gemfile:
gem 'active_record-order_by_ids'
And then execute:
$ bundle install
Or install it yourself as:
$ gem install active_record-order_by_ids
Usage
This gem adds two methods to active record scopes: .order_by_ids
, and the more general .order_by
.
Examples:
user1 = User.create(id: 1)
user2 = User.create(id: 2)
user3 = User.create(id: 3)
User.order_by_ids([2,3,1]) #=> [user2, user3, user1]
user3 = User.create(parent_id: 3)
user2 = User.create(parent_id: 2)
user1 = User.create(parent_id: 1)
User.order_by(parent_id: [2,3,1]) #=> [user2, user3, user1]
Development

To install this gem onto your local machine, run bundle exec rake install
. To release a new version, update the version number in version.rb
, and then run bundle exec rake release
