ozataman-acts-as-taggable-on
Advanced tools
This plugin was originally based on Acts as Taggable on Steroids by Jonathan Viney. It has evolved substantially since that point, but all credit goes to him for the initial tagging functionality that so many people have used.
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.
Acts As Taggable On is available both as a gem and as a traditional plugin. For the traditional plugin you can install like so (Rails 2.1 or later):
script/plugin install git://github.com/mbleigh/acts-as-taggable-on.git
For earlier versions:
git clone git://github.com/mbleigh/acts-as-taggable-on.git vendor/plugins/acts-as-taggable-on
Acts As Taggable On is also available as a gem plugin using Rails 2.1's gem dependencies. To install the gem, add this to your config/environment.rb:
config.gem "mbleigh-acts-as-taggable-on", :source => "http://gems.github.com", :lib => "acts-as-taggable-on"
After that, you can run "rake gems:install" to install the gem if you don't already have it. See http://ryandaigle.com/articles/2008/4/1/what-s-new-in-edge-rails-gem-dependencies for additional details about gem dependencies in Rails.
** NOTE ** Some issues have been experienced with "rake gems:install". If that doesn't work to install the gem, try just installing it as a normal gem:
gem install mbleigh-acts-as-taggable-on --source http://gems.github.com
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
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:"awesome">,<Tag name:"slick">,<Tag name:"hefty">] @user.skills # => [<Tag name:"joking">,<Tag name:"clowning">,<Tag name:"boxing">]
User.find_tagged_with("awesome", :on => :tags) # => [@user] User.find_tagged_with("awesome", :on => :skills) # => []
User.tagged_with("awesome", :on => :tags) # => [@user] User.tagged_with("awesome", :on => :skills) # => []
@frankie = User.create(:name => "Frankie", :skill_list => "joking, flying, eating") User.skill_counts # => [,...] @frankie.skill_counts
Acts As Taggable On utilizes Rails 2.1's named_scope to create an association for tags. This way you can mix and match to filter down your results, and it also improves compatibility with the will_paginate gem:
class User < ActiveRecord::Base acts_as_taggable_on :tags named_scope :by_join_date, :order => "created_at DESC" end
User.tagged_with("awesome").by_date User.tagged_with("awesome").by_date.paginate(:page => params[:page], :per_page => 20)
You can find objects of the same type based on similar tags on certain contexts. Also, objects will be returned in descending order based on the total number of matched tags.
@bobby = User.find_by_name("Bobby") @bobby.skill_list # => ["jogging", "diving"]
@frankie = User.find_by_name("Frankie") @frankie.skill_list # => ["hacking"]
@tom = User.find_by_name("Tom") @tom.skill_list # => ["hacking", "jogging", "diving"]
@tom.find_related_skills # => [,] @bobby.find_related_skills # => [] @frankie.find_related_skills # => []
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) # => [,...] @user.tag_counts_on(:customs) User.find_tagged_with("same", :on => :customs) # => [@user]
Tags can have owners:
class User < ActiveRecord::Base acts_as_tagger end
class Photo < ActiveRecord::Base acts_as_taggable_on :locations end
@some_user.tag(@some_photo, :with => "paris, normandy", :on => :locations) @some_user.owned_taggings @some_user.owned_tags @some_photo.locations_from(@some_user)
This plugin is still under active development. Tag caching has not been thoroughly (or even casually) tested and may not work as expected.
