Module: Easyop::Plugins::Transactional

Defined in:
lib/easyop/plugins/transactional.rb

Overview

Wraps the entire operation (including before/after hooks) in a database transaction. On ctx.fail! or any unhandled exception the transaction rolls back.

Supports ActiveRecord and Sequel out of the box.

Usage — include style (classic):

class TransferFunds
  include Easyop::Operation
  include Easyop::Plugins::Transactional
end

Usage — plugin DSL (recommended, works with ApplicationOperation):

class ApplicationOperation
  include Easyop::Operation
  plugin Easyop::Plugins::Transactional
end

Or opt in per operation:

class TransferFunds < ApplicationOperation
  plugin Easyop::Plugins::Transactional
end

To opt out when the parent has it:

class ReadOnlyOp < ApplicationOperation
  transactional false
end
