Module: Dry::Transaction::Extra::Steps::Async

Defined in:

lib/dry/transaction/extra/steps/async.rb

Overview

Executes the step in a background job. Argument is an ActiveJob or anything that implements ‘#perform_later`. This can include other Transactions when using the :perform_later extension.

If the provided transaction implements a ‘validate` step, then that validator will be called on the input before the job is enqueued. This prevents us from enqueuing jobs with garbage arguemnts that can never be run, and limits the params passed through the message body into only those relevant to the job.

Additionally, ActiveJob only allows for the serialization of a few types of values into the message, Strings, Numbers and ActiveRecord::Model instances (via globalid). Anything else will raise an ActiveJob::SerializationError. Calling the validator beforehand helps strip those out as well.

Accepts an optional argument of delay:, to allow for jobs to be performed later, instead of as soon as possible.

Usage:

async GuestsCleanupJob # A job async Guests::CleanStale # A transaction async DoThisLater, delay: 5.minutes # Optional delay for the job
