Rocket Tag

Clean, modern and maintainable, context aware tagging library for rails 3.1 +

Installation

In your gemfile

gem "rocket_tag"

Then at the command line

bundle install

Create the migration at the command line

rails generate rocket_tag:migration
rake db:migrate
rake db:test:prepare

Configuration

Add configurations to config/initializers/rocket_tag.rb:

RocketTag.configure do |config|
  config.force_lowercase = true # Automatically convert all tags to lowercase (optional, default: false)
end

Usage

class TaggableModel < ActiveRecord::Base
	attr_taggable :skills, :habits
end	

item = TaggableModel.create

item.skills = ["kiting", "surfing", "coding"]
item.habits = ["forking", "talking"]

Match any tag across any contexts

TaggableModel.tagged_with ["forking", "kiting"]  

Match all tags across any contexts

TaggableModel.tagged_with ["forking", "kiting"], :all => true

Match any tag on a specific context

TaggableModel.tagged_with ["math", "kiting"], :on => "skills"

Match all tags on a specific context

TaggableModel.tagged_with ["math", "kiting"], :all => true, :on => "skills"

Match a miniumum number of tags

TaggableModel.tagged_with ["math", "kiting", "coding", "sleeping"], :min => 2, :on => "skills"

Match tags to specific contexts

TaggableModel.tagged_with { :skills => ["math", "kiting"], :languages => ["english", "german"]

Take advantage of the tags_count synthetic column returned with every query

TaggableModel.tagged_with(["math", "kiting", "coding", "sleeping"], :on => "skills").where{tags_count>=2}	

Mix with active relation

TaggableModel.tagged_with(["forking", "kiting"]).where( ["created_at > ?", Time.zone.now.ago(5.hours)])  

or even downstream

User.where{email="bradphelan@xtargets.com"}.documents.tagged_with ['kiting', 'math'] , :on => :skills

where we might have

class User < ActiveRecord::Base
  has_many :documents
end

class Document < ActiveRecord::Base
  belongs_to :user
  attr_taggable :tags
end 

Find similar models based on tags on a specific context and return in decending order of 'tags_count'

model.tagged_similar :on => "skills"
model.tagged_similar :on => "habits"

The two cases of tagged_similar below are functionally identical because there are only two contexts specified on the class. If there were three or more contexts specified then the two below would not be identical.

model.tagged_similar :on => ["skills", "habits"]
model.tagged_similar

Find popular tags and generate tags clouds for specific scopes

User.where{email="bradphelan@xtargets.com"}.documents.popular_tags

where we might have

class User < ActiveRecord::Base
  has_many :documents
end

class Document < ActiveRecord::Base
  belongs_to :user
  attr_taggable :tags
end 

and you can access the field tags_count on each Tag instance returned by the above query. Generating the CSS and html for your tag cloud is outside the scope of this project but it should be easy to do.

Alias tags. If you have several tags that means the same things, then create alias for it.

#array with inctances of RocketTag::Tag
tag1, tag2, tag3 = ['ror', 'ruby-on-rails', 'rails'] 
tag1.alias << [tag2, tag3]
#Models with tag `rails`
# returns all Posts with `rails`, `ruby-on-rails` and `ror` tags 
Post.tagged_with(['rails']) 

Contributing to rocket_tag

  • Check out the latest master to make sure the feature hasn't been implemented or the bug hasn't been fixed yet
  • Check out the issue tracker to make sure someone already hasn't requested it and/or contributed it
  • Fork the project
  • Start a feature/bugfix branch
  • Commit and push until you are happy with your contribution
  • Make sure to add tests for it. This is important so I don't break it in a future version unintentionally.
  • Please try not to mess with the Rakefile, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.
