ActiveRepository

ActiveRepository was designed so you can build your Business Models without depending on any ORM. It by default saves your data in memory using ActiveHash (https://github.com/zilkey/active_hash). Then when you decide which ORM you want to use you only have to connect ActiveRepository with it.

Currently it only works with ActiveRecord and/or Mongoid.

It also has the advantage of letting you test directly in memory, with no need to save data on disk, which gives a great boost to your test suite speed.

Here are some data for comparison:

• ActiveRepository: Finished in 0.63357 seconds; 78 examples, 0 failures

• ActiveRecord: Finished in 3.78 seconds; 78 examples, 0 failures

• Mongoid: Finished in 5.25 seconds; 78 examples, 0 failures

With ActiveRepository you can make associations with ActiveRecord, Mongoid and ActiveRepository seamlessly.

Requirements

Ruby

ActiveRepository requires Ruby version >= 1.9.3.

Installation

Add this line to your application's Gemfile:

gem 'active_repository'

And then execute:

$ bundle

Or install it yourself as:

$ gem install active_repository

Usage

To use it you should inherit ActiveRepository::Base:

class User < ActiveRepository::Base
end

ActiveRepository::Base has two class attributes to help it identify where it is going to persist data

model_class

This attribute is used to identify the class responsible for persisting data, it should be the ActiveRecord model or the Mongoid Document.

save_in_memory

This attribute is used to persist data directly into memory. When set to true, it ignores the model_class attribute value and save in the memory, if set to false it user model_class to persist data.

P.S.: Just be careful, the set_save_in_memory method should always be called after set_model_class method.

class User < ActiveRepository::Base
  # Defines the class responsible for persisting data
  set_model_class(UserModel)

  # Set this to true in order to ignore model_class attribute and persist in memory
  set_save_in_memory(true)
end

Then, you have only to set the fields it is going to use:

class User < ActiveRepository::Base
  # Defines the fields of the class
  fields :name, :email, :birthdate

  set_model_class(UserModel)

  set_save_in_memory(true)
end

Now you are all set and ready to go. It is just using ActiveRepository as if it was your ActiveRecord model or Mongoid Document.
