Hey folks, we've been working on a gradual migration from DelayedJob to ActiveJob within the DEV codebase.

Move delay calls to ActiveJob #3136

lightalloy posted on Jun 12, 2019

As described in #2497, to be less dependent of DelayedJob we also need to move jobs which are created by calling delay method to ActiveJob:

Here is the list of the calls:

[x] Slackbot.ping
[x] reaction.create
[x] ArticleAnalyticsFetcher.new.update_analytics
[x] HtmlVariantSuccess.create
[x] HtmlVariantTrial.create
[x] message.send_push
[x] RssReader.new.fetch_user
[x] several calls in trigger_delayed_index
[x] index.delay.delete_object("users-#{id}")
[x] user.follow
[x] chat_channel.delay.index! - https://github.com/thepracticaldev/dev.to/pull/4317

Actions for each of the calls:

create a corresponding ActiveJob, specify a queue name
call the required method inside a job
replace the delay method calls with a job perform_later call
you may need to modify the existing tests by using perform_enqueued_job instead of run_background_jobs_immediately helper

Remember to pass record ids (if needed) instead of ActiveRecord objects to a job to avoid deserialization errors (#1621)

Take a look at the issue. We have a lot of merged pull requests to use as a guideline to get you started, for example...
