RateableAttributes¶ ↑

RateableAttributes is a re-implementation of ActsAsRateable for multiple attribute support.

To install as plugin:

script/plugin install git://github.com/sdepold/rateable_attributes.git

In order to create the rating table just run the following commands:

script/generate rateable_attributes
rake db:migrate

This will generate a migration. Run rake db:migrate.

rateable_attributes :graphics, :sound, :whatever, :range => 1..5

This allows you to rate the model for the attributes graphics, sound and whatever. To do so use

my_model.rate(3, a_user[, :the_attribute]) # you can just ignore the attribute to create a general rating
my_model.rate_graphics(3, a_user) # equals my_model.rate(3, a_user, :graphics)

RateableAttributes a method to the model called visualize_average_rating. It can be called the following options:

• attribute = The attribute you want to display. Default: nil

• image_rated = The image/symbol you wish to be shown as reached rating. Default: A yellow star

• image_unrated = The image/symbol you wish to be shown as unreached rating. Default: A white star

• image_hover = The image/symbol you wish to be shown when hovering one of the rating images (see next option). Default: An orange star

• enable_rating = Should the user be able to click and rate?

• click_url = The URL which gets called, when a user clicked on a star to rate the model.

When you enable the rating option, the controller should return a json object as follows:

{new_rating: 2}

Important as well is, that you include the generated javascript file. Just do the following in your documents head:

= javascript_include_tag "rateable_attributes.js"

The javascript uses the prototype plugin. Feel free to change it for JQuery if you are using it.
