ListSorter

This plugin is an adapted version of Recipe 5 of Chad Fowler’s Rails Recipes.

ListSorter provides a common interface to sort ActiveRecord models you’re representing via html lists (

or
) in your view templates.

There are two methods in the ListSorter module.

collection_sort – This method sorts a collection of one AR object’s child models. I originally used it to sort a Product’s photos.

Requirements

1. Prototype + Scriptaculous 3. acts_as_list plugin (or possibly some derivative of this, though I haven’t tested any others so I can’t be sure)

Example

In your models:

class Product < ActiveRecord::Base
    has_many :photos, :order => :position
end

class Photo < ActiveRecord::Base
    acts_as_list :scope => :product
end

In your controller:

class ProductsController < ActionController::Base sort_list ‘bios’ end

private
  def index
    bios = sortable_list
  end

def sortable_list
  Products.all(:order => 'position')
end

In routes.rb:

map.sort “products/sort/:id/:parent/:children”, :controller => ‘products’, :action => ‘sort’
