|
|
||
|
|
### 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
