After Transaction Commit

ActiveRecord::Base.connection.after_transaction_commit { ... }

Build Status

An ActiveRecord extension that allows writing callbacks to run after the current transaction commits. This is similar to the built-in ActiveRecord::Base#after_commit functionality, but more flexible, and doesn't require putting the callback on a specific model.

Callbacks will only run once, on the next commit, not after every subsequent commit. Callbacks will never run if the transaction rolls back.

Installation

Add this line to your application's Gemfile:

gem 'after_transaction_commit'

And then execute:

$ bundle

Or install it yourself as:

$ gem install after_transaction_commit

Usage

ActiveRecord::Base.transaction do
  ActiveRecord::Base.connection.after_transaction_commit { run_some_background_job }
  # run_some_background_job has not run yet
end
# now, it has run

# this one runs immediately, since we are outside a transaction
ActiveRecord::Base.connection.after_transaction_commit { some_other_task }

Usage in Tests

If you want to write tests that interact with after_transaction_commit callbacks, pull in the test_after_commit gem in your test environment, and things will work as expected. See that gem's README for installation instructions.
