Transactions

Transactions

As your business logic gets complex you may need to implement transactions. The classic example is a bank funds transfer from account A to account B. If the withdrawal from account A fails then the deposit to account B should either never take place or be rolled back.

Basics

All the complexity is handled by ActiveRecord::Transactions. Any model class or instance has a method named .transaction. When called and passed a block, that block will be executed inside a database transaction. If there's an exception raised, the transaction will automatically be rolled back.

Example

Integration test with Omniauth. This example is using twitter, and assume you've installed rspec and capybara. Official document is here: https://github.com/intridea/omniauth/wiki/Integration-Testing
# in spec/support/omniauth_macros.rb
module OmniauthMacros
def mock_auth_hash
# The mock_auth configuration allows you to set per-provider (or default)
# authentication hashes to return during integration testing.
OmniAuth.config.mock_auth[:twitter] = {
'provider' => 'twitter',
'uid' => '123545',
'user_info' => {
'name' => 'mockuser',
