Rails - Sep 2009 - Transaction blocks and rollbacks

Hello, I''m beginning to test a payment method, here is an abbreviated
form.

How can I rollback and redo the transaction if any of the save calls
fail?

  def process_payment!  # class Payment
    transaction do
      success = true

      user.blitz_interest = true
      user.points += 1
      user.blitz_contributes += DIVIDEND

      user.credit.pebbles += 1

      blitz_fund = BlitzFund.find_or_create_by_dues(DIVIDEND)
      blitz_fund.general_pool += DIVIDEND

      save
      user.save
      user.credit.save
      blitz_fund.save
    end
  end

The simplest way is:

raise ActiveRecord::Rollback

which will roll the whole transaction it''s executed inside of back.

Hi  Jesse Crockett

  Like

ActiveRecord::Base.transaction do

end
