Dynamicly add unlimited number of indexed, searchable, validatable, strongly typed fields to your ActiveRecord models.
Add this line to your application's Gemfile:
gem 'acts_as_metadata'
And then execute:
$ bundle
Or install it manually:
$ gem install acts_as_metadata
Generate migration that creates metadata tables:
$ rails g metadata:migration
Add acts_as_metadata to your model:
class MyModel < ActiveRecord::Base
acts_as_metadata
end
and create metadata_cache column to speed up metadata extraction:
rails g migration AddMetadataCacheToMyModels metadata_cache:text
Create metadata types in your database:
mt = MetadataType.create! :tag => :sample, :name => "Sample", :datatype => :string
Its ready to use:
m = MyModel.new
m.m_sample = 'some string'
m.save!
Add some validations or default value if you need:
mt.default = 'some default string'
mt.mandatory = true # presence validation
mt.regexp = "[a-z]*" # regexp validation
mt.values = ['aaa', 'bbb', 'ccc'] # inclusion validation
mt.save!
There are more usage examples in spec directory.
