= acts_as_taggable_on_steroids This plugin is based on acts_as_taggable by DHH but includes extras such as tests, smarter tag assignment, and tag cloud calculations. Thanks to www.fanacious.com for allowing this plugin to be released. Please check out their site to show your support. == Resources Install * script/plugin install http://svn.viney.net.nz/things/rails/plugins/acts_as_taggable_on_steroids == Usage === Basic tagging Using the examples from the tests, let's suppose we have users that have many posts and we want those posts to be able to be tagged by the user. As usual, we add +acts_as_taggable+ to the Post class: class Post < ActiveRecord::Base acts_as_taggable belongs_to :user end We can now use the tagging methods provided by acts_as_taggable, <tt>tag_list</tt> and <tt>tag_list=</tt>. Both these methods work like regular attribute accessors. p = Post.find(:first) p.tag_list # "" p.tag_list = "Funny, Silly" p.save p.reload.tag_list # "Funny, Silly" === Tag cloud calculations To construct tag clouds, the frequency of each tag needs to be calculated. Because we specified +acts_as_taggable+ on the <tt>Post</tt> class, we can get a calculation of all the tag counts by using <tt>Post.tag_counts</tt>. But what if we wanted a tag count for an individual user's posts? To achieve this we extend the <tt>:posts</tt> association like so: class User < ActiveRecord::Base has_many :posts, :extend => TagCountsExtension end This extension now allows us to do the following: User.find(:first).posts.tag_counts This can be used to construct a tag cloud for the posts of an individual user. The +TagCountsExtension+ should only be used on associations that have +acts_as_taggable+ defined. Problems, comments, and suggestions all welcome. firstname.lastname@example.org == Credits www.fanacious.com
