RailsDependsOn

A simple rails engine to make it easier to use the great DependsOn jQuery Plugin:

http://dstreet.github.io/dependsOn/

Note: not all the features of the original plugin are implemented for now

Installation

Add this line to your application's Gemfile:

gem 'rails_depends_on'

And then execute:

$ bundle

Or install it yourself as:

$ gem install rails_depends_on

Include the assets in your javascript manifest file:

//= require dependent-fields to your Javascript manifest file (usually found at app/assets/javascripts/application.js).

Usage

   = f.input 'a_checkbox'
  .depends-on{"data-id" => 'a_checkbox', 'data-value' =>'true'}
    = f.input 'another_field'

   = f.input 'a_text_field'
  .depends-on{"data-id" => 'a_text_field', 'data-value' =>[['1'],['2']]}
    = f.input 'another_field'

   = f.input 'a_text_field'
  .depends-on{"data-id" => 'a_text_field', 'data-qualifier'=> 'not', 'data-value' =>[['1'],['2']]}
    = f.input 'another_field'

   = f.input 'a_multiple_select'
  .depends-on{"data-id" => 'a_multiple_select', 'data-qualifier'=> 'contains', 'data-value' =>[['1'],['2']]}
    = f.input 'another_field'

   = f.input 'a_text_field'
  .depends-on{"data-id" => 'a_text_field', 'data-qualifier'=> 'email', 'data-value' => 'true'}
    = f.input 'another_field'

   = f.input 'a_text_field'
  .depends-on{"data-id" => 'a_text_field', 'data-qualifier'=> 'url', 'data-value' => 'true'}
    = f.input 'another_field'

   = f.input 'a_text_field'
  .depends-on{"data-id" => 'a_text_field', 'data-qualifier'=> 'match', 'data-value' => '\da{3}'}
    = f.input 'another_field'

   = f.input 'a_radio_buttone'
  .depends-on{"data-name" => 'a_radio_button', 'data-qualifier'=> 'match', 'data-value' => ['1','2']}
    = f.input 'another_field'

TODO

• Multiple dependencies
• Regexp qualifier
• Custom Qualifiers
• implement all dependsOn options (callbacks etc..)
