+# SeemsRateable
+
+Star rating gem for Rails application using jQuery plugin <a href="http://www.myjqueryplugins.com/jquery-plugin/jrating">jRating</a>
+
+## Demo
+
+<a href="http://rateable.herokuapp.com/">Demo</a> application, requires to sign up before rating
+
+## Instructions
+
+### Installation
+
+Add this line to your application's Gemfile:
+
+    gem 'seems_rateable'
+
+And then execute:
+
+    $ bundle
+
+Or install it yourself as:
+
+    $ gem install seems_rateable
+
+### Generation
+
+	$ rails generate seems_rateable:install
+	
+Generator creates migration files, javascript files and initializer
+
+### Prepare
+
+Require javascript files by adding this line to application.js
+
+	#application.js
+	//= require_directory ./rateable
+
+Add <code>seems_rateable</code> to routes.rb file
+
+Include stylesheet adding <code><%= seems_rateable_stylesheet %></code> to your layout header
+
+Also make sure you have an existing <code>current_user</code> helper method	
+
+Don't forget to run
+
+	$ rake db:migrate
+
+To prepare model add <code> seems_rateable </code> to your rateable model file. You can also pass a hash of options to 
+customize the functionality
+
+<ul>
+<li><code>:dimensions</code>Array of dimensions e.g <code>:dimensions => [:quality, :quantity]</code> </li>
+<li><code>:allow_update</code>Allowing user to re-rate his own ratings, default set to false e.g <code>:allow_update=> true</code></li>
+</ul>
+
+	class Post < ActiveRecord::Base
+		seems_rateable :allow_update => true, :dimensions => [:quality, :length]
+	end
+
+To access object's rates use <code>rates</code> method, to get dimension rates pass an argument eg :
+
+	@object.rates
+	@object.rates(:quality)
+	@object.rates(:quantity)
+	
+This also applies to cached average rating e.g
+
+	@object.average	
+	@object.average(:quality)
+	@object.average(:quantity)
+	
+And to object's raters e.g
+	
+	@object.raters
+	@object.raters(:quality)
+	@object.raters(:quantity)
+	
+To track user's given ratings add <code>seems_rateable_rater</code> to your rater model.
+If your rater class is not "User"(e.g "Client" or "Customer") change configuration in initializer generated by this engine. 
+Now you can access user's ratings by <code>@user.ratings_given</code>
+
+### Usage
+
+To display star rating use helper method <code>rating_for</code> in your view
+
+    #index.html.erb
+    
+    rating_for @post
+    
+    rating_for @post, :dimension => :quality, :class => 'post', :id => 'list'
+    
+    rating_for @post, :static => true
+ 
+You can specify these options :
+<ul>
+<li><code>:dimension</code>The dimension of the object</li>
+<li><code>:static</code>Set to true to display static star rating, default false</li>
+<li><code>:class</code>Class of the div, default set to 'rateable'</li>
+<li><code>:id</code>ID of the div e.g <code>:id => "info"</code>, default nil</li>
+</ul>
+
+To edit the javascript options locate rateable.js file in /app/assets/javascripts/rateable/.
+The javascript options are explained directly in the file
