Acts As Taggable On

This plugin is heavily based on Acts as Taggable on Steroids by Jonathan Viney. While basic tagging functionality is handled expertly as well as tag cloud calculations, for many applications there may be a need to have several “tag fields” for a given model.

For instance, in a social network, a user might have tags that are called skills, interests, sports, and more. There is no real way to differentiate between tags and so an implementation of this type is not possible with acts as taggable on steroids.

Enter Acts as Taggable On. Rather than tying functionality to a specific keyword (namely “tags”), acts as taggable on allows you to specify an arbitrary number of tag “contexts” that can be used locally or in combination in the same way steroids was used.

Installation

The simplest way is just to install straight from the SVN:

script/plugin install http://svn.intridea.com/svn/public/acts_as_taggable_on

Testing

Acts As Taggable On uses RSpec for its test coverage. If you already have RSpec on your application, the specs will run while using:

rake spec:plugins

Example

class User < ActiveRecord::Base acts_as_taggable_on :tags, :skills, :interests end

@user = User.new(:name => “Bobby”) @user.tag_list = “awesome, slick, hefty” # this should be familiar @user.skill_list = “joking, clowning, boxing” # but you can do it for any context! @user.skill_list # => [“joking”,”clowning”,”boxing”] as TagList @user.save

@user.tags # => [<tag name:>,<tag name:>,<tag name:>] @user.skills # => [<tag name:>,<tag name:>,<tag name:>]

User.find_tagged_with(“awesome”, :on => :tags) # => [@user] User.find_tagged_with(“awesome”, :on => :skills) # => []

@frankie = User.create(:name => “Frankie”, :skill_list => “joking, flying, eating”) User.skill_counts # => [<tag name=”joking” count=”2”>,<tag name=”clowning” count=”1”>...] @frankie.skill_counts

Dynamic Tag Contexts

In addition to the generated tag contexts in the definition, it is also possible to allow for dynamic tag contexts (this could be user generated tag contexts!)

@user = User.new(:name => “Bobby”) @user.set_tag_list_on(:customs, “same, as, tag, list”) @user.tag_list_on(:customs) # => [“same”,”as”,”tag”,”list”] @user.save @user.tags_on(:customs) # => [<tag name=”same”>,...] @user.tag_counts_on(:customs) User.find_tagged_with(“same”, :on => :customs) # => [@user]
