Rails 7.2.X breaks enqueuing without `enqueue_after_transaction_commit?` method on queue adapters

[tostart-pickagreatname]

Rails 7.2.1 requires that queues implement the enqueue_after_transaction_commit? method.

The impact of not having this method and upgrading to 7.2.1 is that all job enqueuing fails.

This method is described in rails/rails@e922c59

This commit also introduced ActiveJob::QueueAdapters::AbstractAdapter which all rails queues now inherit from.

In the future, the best path would be to have the adapter inherit from AbstractAdapter, to avoid new methods breaking job enqueuing.

At this time, however, its default behaviour could simply be implemented.

Update, the change actually came in 7.2 not 7.2.1.

A workaround for whoever ran into this issue with Rails 7.2 and Que 2.4—put this in your app/jobs/application_job.rb.

class ApplicationJob < ActiveJob::Base
  # Automatically retry jobs that encountered a deadlock
  # retry_on ActiveRecord::Deadlocked

  # Most jobs are safe to ignore if the underlying records are no longer available
  # discard_on ActiveJob::DeserializationError

  # Wait for the transaction to commit before enqueuing
  self.enqueue_after_transaction_commit = :always
end

This recommendation by @scomma does not seem to fix it for us.
We added to our application.rb the following

  config.active_job.enqueue_after_transaction_commit = :always

This allowed us to run on rails 7.2 and the latest Que (2.4.1)
