Transacted

A library to make writing transactional code easier.

Installation

Add this line to your application's Gemfile:

gem 'transacted'

And then execute:

$ bundle

Or install it yourself as:

$ gem install transacted

Usage

Require it in your file:

require 'transacted'

Then you can initialize Actions:

action_options = {
  up: -> {puts "Up !"},
  down: -> {puts "Down !"}
}
action = Transacted::Action.new action_options

You can then create a Transaction out of Actions :

first_action_options = {
  up: -> {puts "First up !"},
  down: -> {puts "First down !"}
}
first_action = Transacted::Action.new first_action_options

second_action_options = {
  up: -> {puts "Second up !"},
  down: -> {puts "Second down !"}
}
second_action = Transacted::Action.new second_action_options

transaction = Transacted::Transaction.new [first_action, second_action]

And execute it =

transaction_status = transaction.execute
# First up !
# Second up !

transaction_status would be either

• :execution_success : if all the actions are executed successfully
• :rollback_success : if an action has failed and the rollback was made successfully
• :rollback_failure : if an action has failed during execution, and another failure was encountered during rollback. The transactionality is lost in such cases since the rollback was not successful.
