raty-rails

Introduction

raty-rails is a Ruby gem that wraps the [jQuery Raty][] plugin, allowing its image and Javascript files to be served via the [Rails][] [asset pipeline][].

[jQuery Raty][] is a useful "star rating" [jQuery][] plugin.

This project is not officially associated with the [jQuery Raty][] project.

Installation

Install the gem

raty-rails requires Rails 3, since it depends on the asset pipeline.

To install, add one of the following to your Rails project's Gemfile:

gem 'raty-rails', github: 'yuanping/raty-rails' # Bleeding edge

Then, install the gem by running bundle install.

Configure the assets

Modify the [Sprockets manifest][] in your application.js file to include one of the following, depending on whether you want to include the compressed Javascript or the uncompressed Javascript:

You'll also need to include raty_rails in your scripts for this to work.

//= require jquery.raty
//= require raty_rails


// as CSS
*= require jquery.raty

Usage

At this point, your Rails application has access to jQuery Raty. See the [jQuery Raty][] web site for instructions on how to use the plugin.

Making Things Rating

raty-rails provides a helper method in your view to make your model values ratable. By default, you need to specify the model and property that should be rating. A div element is rendered with data-* attributes used by JQuery Raty.

%h1= rating_for @model, :name

You can customize the tag name and title attribute:

• title - The model and attribute name are used to create a capitalized title

The rating_for helper method automatically adds these data-* attributes used by raty.

• url - Uses the polymorphic_path(model) helper method.
• class - "class" attribute on element.
• value - Uses model.name.
• number - The number of stars.
• cancel - Add a cancel button on the left side of the stars to cacel the score.

# example of nested resource
%h1= rating_for [picture.gallery, picture], :name, class: 'custom-style'


## Notes

* The [jQuery Raty][] images are installed so that their assets paths won't
  conflict with same-named images in the application or in other gems.
