Nube

Nube aims to be as flexible and abstract as possible while helping you work with remote object in different Rails applicaction as activerecord objects. It's 100% compatible with Associations (Locals-Remotes, Remote-Remote, Remote-local), Scopes, Validations. Besides is posible work with object from different Rails applications.

Installation

Add this line to your application's Gemfile:

gem 'nube'

And then execute:

$ bundle

Or install it yourself as:

$ gem install nube

Usage

Associations

Its possible define relations between differents class, locals with remotes. It's possible use any options, as, dependent, foreing_key, , class_name, etc. For local class is only necessary:

  1. Add include LocalAssociation.
  2. Define associations as activerecord but use remote_ when you like define one relation with a remote class, for example: remote_belongs_to, remote_has_one, remote_has_many.

For Remote class is only necessary:

  1. All remote class inherits from Nube::Base.
  2. All relation definition is with remote_

Examples:

Local class with Remote class or Remote class with Local class

    # Rails app A with the persisting object
	Class Client < ActiveRecord::Base
      include LocalAssociation
      remote_has_one :remote_class, dependent: :nullify, foreign_key: "remote_class_foreign_key_id"
      remote_has_one :other_remote_class, through: :foo
      remote_has_many :foo_bar_remote_class, class_name: "RemoteClass", foreign_key: 'foo_bar_remote_class_id'
      belongs_to :remoteable, polymorphic: true
      belong_to :bar
    end

    # Rails app A with the persisting object
    class Bar < ActiveRecord::Base
      has_one :client
    end

    # Rails app B without the persisting object
    class Remote_class << Nube::Base
      remote_belongs_to :client
      remote_has_many :clients
      has_many :clients, as: :remoteable, class_name: "Client", dependent: :destroy
    end

Remote class with Remote class

    # Rails app B without the persisting object
	Class Client < Nube::Base
      include LocalAssociation
      remote_has_one :remote_class, dependent: :nullify, foreign_key: "remote_class_foreign_key_id"
      remote_has_one :other_remote_class, through: :foo
      remote_has_many :foo_bar_remote_class, class_name: "RemoteClass", foreign_key: 'foo_bar_remote_class_id'
      remote_belongs_to :remoteable, polymorphic: true
    end

    # Rails app B without the persisting object
    class Remote_class < Nube::Base
      remote_remote_belongs_to :client
      remote_has_many :clients
      remote_has_many :clients, as: :remoteable, class_name: "Client", dependent: :destroy
    end

Scopes

    # Rails app A with the persisting object
    Class Client < ActiveRecord::Base # Rails app A
	  scope :submitted, -> { where(submitted: true) }
      scope :newer_than, -> (date1, date2) { where('start_date > ? and start_date < ?', date1, date2) }
      scope :late, -> { where("timesheet.submitted_at <= ?", 7.days.ago) }
    end

    # Rails app B without the persisting object
    class Client < Nube::Base
      scope :submitted # Only define the name
	  scope :newer_than, using: [:date1, :date2] # Onlye define scope name, and options.
	  scope :foo, remote_scope: :late  #Online define name. In this case the scope it's renamed
    end

Validations

The validations must be defined where activerecord models exist. So when a class it's defined as Nube::Base, it's not necessary define any validations.

API Controller

It's only necessary define:

	class AnyController < ApplicationController
	  include NubeController
	  RESOURCE = ModelName
	end

The public action are:

  1. index
  2. count
  3. create
  4. update
  5. update_all
  6. destroy_all

Development

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.
