Transaction Strategy

The transaction strategy wraps your action execution in a database transaction:

class TransferFunds
  include Action

  use :transaction

  expects :from_account, :to_account, :amount

  def call
    from_account.withdraw!(amount)
    to_account.deposit!(amount)
    expose :transfer_id, SecureRandom.uuid
  end
end

Important: The transaction wraps the entire action execution, including:

• before hooks
• The main call method
• after hooks
• Success/failure callbacks (on_success, on_failure, etc.)

This means that if any part of the action (including hooks or callbacks) raises an exception or calls fail!, the entire transaction will be rolled back.

Requirements: Requires ActiveRecord to be available in your application.
