Activerecord::WrappedTransaction

Wrap transactions in a way that lets you easily detect if the block succeeded or rolled back for complex, procedural usage with an object interface.

It supports MySQL, PostgreSQL, and SQLite.

Installation

Add this line to your application's Gemfile:

gem 'activerecord-wrapped_transaction'

And then execute:

$ bundle

Or install it yourself as:

$ gem install activerecord-wrapped_transaction

Usage

ActiveRecord::Base.include ActiveRecord::WrappedTransaction

wrapped_result = ActiveRecord::Base.wrapped_transaction do
  # Do something
end

wrapped_result.result # 
wrapped_result.success?
wrapped_result.rolled_back?

You can pass the same options you would to ActiveRecord::Base.transaction: requires_new, isolation, joinable

Todo

• Test coverage for multiple connections (should be supported, but not guaranteed)
• Maybe monad support for being able to execute complex logic more fluently.

Development
