ActiveRecord::OrderByIds

Build Status Code Climate

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

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

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, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
