after_commit(ignore_errors: false, &block) click to toggle source

Workflow#after_commit will accept a block to execute after the transaction commits. This is very useful to isolate side-effects. They will run only on the transaction’s success and will not be able to roll it back when there is an exception. Useful if your background jobs processor is not using the same database connection to enqueue jobs.

def after_commit(ignore_errors: false, &block)
  Sequent.configuration.transaction_provider.after_commit(&block)
rescue StandardError => e
  if ignore_errors
    Sequent.logger.warn("An exception was raised in an after_commit hook: #{e}, #{e.inspect}")
  else
    raise e
