RailsSandbox

a tiny gem that provides a protective sandbox for database transactions.

this gem is based on the magic of ActiveRecord::Base#transaction.

Add this line to your application's Gemfile:

gem 'rails_sandbox'

And then execute:

$ bundle

Or install it yourself as:

$ gem install rails_sandbox

in your model:

# app/models/my_model.rb

require 'rails_sandbox'

class MyModel
  def json_with_updated_attributes(params)
    # the json result with updated attributes will be returned while the actual
	# record keeps unchanged
    ActiveRecord::Base.sandbox do
	  self.update_attributes(params)
	  self.to_json
	end
  end

end
