green_light <img src=“https://travis-ci.org/overture8/green_light.svg?branch=master” alt=“Build Status” />¶ ↑

Provides client side validation, with the help of the jquery validation plugin. Keeping validation in the model, where it belongs.

Installation¶ ↑

Add green_light to your Gemfile and run the bundle install command.

gem 'green_light'

Usage¶ ↑

Include the JQuery validation plugin in your app/assets/javascripts/application.js file:-

//= require jquery.validate

Since the validation rules are creating dynmically they need to be included in the header of your layout file:-

<%= javascript_include_tag "green_light" %>

Add the green_light class to the forms that you wish to have client side validation:-

<%= form_for(@model, :html => { :class => 'green_light' }) do |f| %>

And finally, add some validations to your models!

Currently Supports these validations¶ ↑

validates_presence_of
validates_length_of
validates_format_of
validates_uniqueness_of
validates_numericality_of

For validations that are not yet supported, the gem will degrade gracefully to the standard Rails server-side validation.

Legacy Rails 3 Support¶ ↑

For Rails 3 support use the older version (0.0.3) of green_light

Requirements¶ ↑

JQuery is require for the jquery validation plugin. Be sure to include this in your application.js file:-

//= require jquery

Running the Tests¶ ↑

bundle install
bundle exec rspec spec
