Includes:
RailsEventStore::AsyncHandler
Defined in:
app/subscribers/delivery_pre_pack_cancelled_notification_handler.rb

Overview

Sends the pre-pack-cancellation email to the warehouse / requester after
an in-progress pre-pack is aborted.

WHY async via event: the delivery is captured by id at publish time and
re-queried at perform time, so a same-transaction destroy (the
Itemizable purge_empty_quoting_deliveries zombie cleanup) is a clean
no-op instead of ActiveJob::DeserializationError (AppSignal #4958).
Replaces a direct InternalMailer.…deliver_later call whose GlobalID
arg could be invalidated by a destroy in the same transaction before
the after-commit enqueue actually pushed to Redis.

Instance Method Details

#perform(event) ⇒ void

This method returns an undefined value.

Processes a persisted pre-pack cancellation event: clears the delivery's
suggested_packaging_text, resolves the cancelling Party (if its id still
references a live row), and emails the warehouse / requester.

Parameters:

  • event (RubyEventStore::Event) —

    the persisted Events::DeliveryPrePackCancelled event

Raises:

  • (StandardError) —

    if updating the delivery, resolving cancelled_by,
    or sending the notification fails
