Description

Sortiri is a clean and lightweight solution for making ActiveRecord::Base objects sortable.

Getting started

Sortiri is supported for ActiveRecord 4.2+ on Ruby 2.6.0 and later.

In your Gemfile, for the last officially released gem:

gem 'sortiri'

Usage

To add Sortiri to an ActiveRecord::Base object, simply include the Sortiri module.

class User < ActiveRecord::Base
  include Sortiri::Model
end

Ascending

Sorting is ascending by default and can be reversed by adding a hyphen (-) to the start of the property name.

# GET /users?sort=name

class User < ActiveRecord::Base
  include Sortiri::Model

  sortable against: %i[name age weight], default_sort: 'age'
end

# users will be sorted by name and ascending (A -> Z)

Descending

To sort by descending, simply add a hypen (-) to the start of the property name.

# GET /users?sort=-name

class User < ActiveRecord::Base
  include Sortiri::Model

  sortable against: %i[name age weight], default_sort: 'age'
end

# users will be sorted by name and descending (Z -> A)

Default sort option

It is mandatory to provide a default sort option for the model. If nothing is passed, the default sort option will be applied.

# GET /users

class User < ActiveRecord::Base
  include Sortiri::Model

  sortable against: %i[name age weight], default_sort: '-age'
end

# users will be sorted by age and descending

Sorting through associations

It is possible to sort columns on associated models.

You can pass a Hash into the :associated_against option to set up sorting through associations. The keys are the names of the associations and the value works just like an :against option for the other model. Right now, sorting deeper than one association away is not supported.

class Company < ActiveRecord::Base
  has_many :users
end

# GET /users?sort=-company.name

class User < ActiveRecord::Base
  include Sortiri::Model

  belongs_to :company

  sortable against: %i[name age weight], associated_against: { company: [:name] }, default_sort: '-age'
end

# users will be sorted by their companies name and descending (Z -> A)

Controller

Sorted

Allows to specify an order string.

class UsersController < ApplicationController
  def index
    @users = User.sorted(params[:sort])
  end
end

Sorted!

Replaces any existing order defined on the relation with the specified order.

class UsersController < ApplicationController
  def index
    if params[:sort].present?
        @users = User.sorted!(params[:sort])
    else
        @users = User.sorted(params[:sort])
    end
  end
end

Sortiri's sort_link helper creates table headers that are sortable links

To use Sortiri's sort_link helper, simply include the Sortiri module on your ApplicationHelper.

module ApplicationHelper
  include Sortiri::ViewHelpers::TableSorter
end

<%= sort_link(@users, :name, 'First Name') %>

= sort_link @users, :name, 'First Name'

Additionally css classes can be passed after the title attribute.

<%= sort_link(@users, :name, 'First Name', 'd-flex justify-content-center') %>

= sort_link @users, :name, 'First Name', 'd-flex justify-content-center'

Configuration

Sortiri uses default up and down arrows for the view helper. This may be changed by setting them in a Sortiri initializer file (typically config/initializers/sortiri.rb):

Sortiri.configure do |c|
  c.up_arrow = 'fas fa-angle-up'
  c.down_arrow = 'fas fa-angle-down'
end
