NumeritajTipo

NumeritajTipo is yet another enumeration types library. This library does not override any methods defined at ActiveRecord or Mongoid or Neo4jrb.

Add this line to your application's Gemfile:

gem 'numeritaj_tipo'

And then execute:

$ bundle

Or install it yourself as:

$ gem install numeritaj_tipo

class User < ActiveRecord::Base
  include NumeritajTipo::ActiveRecord

  enumerize :role, values: %i(admin user), type: Symbol, default: :user
end

class User
  include Mongoid::Document
  include NumeritajTipo::Mongoid

  field :name
  enumerize :role, values: %i(admin user), type: Symbol, default: :user
end

class User
  include Neo4j::ActiveNode
  include NumeritajTipo::Neo4j

  property :name
  enumerize :role, values: %i(admin user), type: Symbol, default: :user
end

• values:
  • enum values range.
  • values should be Symbol values list.
• type:
  • enum type (describe below).
• default:
  • default value of the attribute.
• allow_nil
  • if true allow the null value, it doesn't allow in the case of false.

user = User.create

user.user?
=> true

user.admin?
=> false

User.roles
=> [:admin, :user]

User.admin.count
=> 1

User.user.count
=> 0

• generate enums

$ rails g enum Role admin user

will generate enum type under app/enums:

• app/enums/role.rb:

NumritajTipo.define_enum :Role, %i{
  admin
  user
}

• using enum

class User < ActiveRecord::Base
  include NumeritajTipo::ActiveRecord

  enumerize :role, type: 'Role', default: :user
end

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
