Instructions

Install

Add the ratyrate gem into your Gemfile

gem 'ratyrate'

Generate

rails g ratyrate user

The generator takes one argument which is the name of your existing devise user model UserModelName. This is necessary to bind the user and rating datas. Also the generator copies necessary files (jQuery Raty plugin files, star icons and JavaScript files)

Example:

Suppose you will have a devise user model which name is User. The devise generator and ratyrate generator should be like below

rails g devise:install
rails g devise user

rails g ratyrate user # => user is the model generated by devise

This generator will create Rate and RatingCache models, db/migrations, and link to your user model.

Database Migration

Run the migrations:

rake db:migrate

Javascript include

//= require jquery.raty
//= require ratyrate

Prepare

I suppose you have a car model

rails g model car name:string

You should add the ratyrate_rateable function with its dimensions option. You can add multiple dimensions.

class Car < ActiveRecord::Base
  ratyrate_rateable "speed", "engine", "price"
end

Then you need to add a call ratyrate_rater in the user model.

class User < ActiveRecord::Base
  ratyrate_rater
end

Using

There is a helper method which name is rating_for to add the star links. By default rating_for will display the average rating and accept the new rating value from authenticated user.

<%# show.html.erb -> /cars/1 %>

Speed  : <%= rating_for @car, 'speed' %>
Engine : <%= rating_for @car, 'engine' %>
Price  : <%= rating_for @car, 'price' %>

Available Options

1- If you need to change the star number, you should use star option like below.

Speed  : <%= rating_for @car, 'speed', star: 10 %>
Engine : <%= rating_for @car, 'engine', star: 7 %>
Price  : <%= rating_for @car, 'price' %>

2- If you want to disable/enable the rating after user's first rate use the new option disable_after_rate

Speed : <%= rating_for @car, 'speed', disable_after_rate: true %>

To enable changes after first user rate set disable_after_rate to false

3- To enable half stars use the option enable_half

Speed : <%= rating_for @car, 'speed', enable_half: true %>

4- To show or hide the half stars use half_show

Speed : <%= rating_for @car, 'speed', half_show: true %>

5- To change the path in which the star images (star-on.png, star-off.png, star-half.png, ..etc) are located use

Speed : <%= rating_for @car, 'speed', star_path: true %>

To just change one of the star images choose from these options (star_on, star_off, star_half)

6- To add the cancel button to the left, or right of the stars use (default is false)

Speed : <%= rating_for @car, 'speed', cancel: true %>

7- To change the place of the cancel button (left, or right) use (default is left)

Speed : <%= rating_for @car, 'speed', cancel_place: left %>

8- To change the hint on the cancel button use (default is "Cancel current rating!" )

Speed : <%= rating_for @car, 'speed', cancel_hint: 'Cancel this rating!' %>

9- To change the image of the cancel on button use

Speed : <%= rating_for @car, 'speed', cancel_on: 'cancel-on2.png' %>

10- To change the image of the cancel off use

  Speed : <%= rating_for @car, 'speed', cancel_off: 'cancel-off2.png' %>

Other Helpers

You can use the rating_for_user helper method to show the star rating for the user.

Speed : <%= rating_for_user @car, current_user, 'speed', star: 10 %>

And you can use the imdb_style_rating_for to show a similar to IMDB rating style.

Speed : <%= imdb_style_rating_for @car, current_user %>

Semantic Versioning

Ratyrate attempts to follow semantic versioning in the format of x.y.z, where:

x stands for a major version (new features that are not backward-compatible).

y stands for a minor version (new features that are backward-compatible).

z stands for a patch (bug fixes).

In other words: Major.Minor.Patch.
