Enhances Rails with database-backed ordered sorting via controllers, models, and views.
- Enables models to be sortable.
- Adds view helpers and jQuery UI positioning controls with AJAX support.
- Enables controllers to handle sortable resources (i.e. models) and respond to AJAX requests.
For a secure install, type the following from the command line (recommended):
gem cert --add <(curl -Ls http://www.redalchemist.com/gem-public.pem) gem install sorter --trust-policy MediumSecurity
NOTE: A HighSecurity trust policy would be best but MediumSecurity enables signed gem verification while allowing the installation of unsigned dependencies since they are beyond the scope of this gem.
For an insecure install, type the following (not recommended):
gem install sorter
Add the following to your Gemfile file:
Add the following to your application.js file:
//= require jquery.sorter
Add the following to your application.css file:
*= require jquery.sorter
For models, add the following:
class Photo < ActiveRecord::Base is_sortable end
This assumes the column used for storing position information is called "position". If this is not the case, you can change the defaults as follows:
class Photo < ActiveRecord::Base is_sortable column: :rank end
For controllers, add the following:
class PhotosController < ApplicationController is_sortable end
This assumes the resource (i.e. model) associated with this controller is call Photo. If this is not the case, you can change the defaults as follows:
class PhotosController < ApplicationController is_sortable model_class: RecordPhoto end
This will allow you to use the render_position_control helper method which will yield position controls (i.e. drag-n-drop, move to top, move up by one, move down by one, and move to bottom). All changes take place via AJAX calls back to your controller so that changes in your views are reflected back in the database.
To test, do the following:
- cd to the gem root.
- bundle install
- bundle exec rspec spec
