Rails 7.1: solution with background job execution timing affecting user notifications
I'm deploying to production and After trying multiple solutions online, I still can't figure this out. I'm working with an scenario with background jobs in my Rails 7.1 application where user notifications are being sent out at unexpected times. I'm using Sidekiq for processing background jobs and ActionMailer to send email notifications. The question arises when I enqueue jobs that depend on the completion of previous jobs, but it seems like they are executing out of order, causing users to receive notifications before their actions are fully processed. For instance, I have a job called `NotifyUserJob` that is enqueued after a user completes a purchase. This job sends them a confirmation email. However, sometimes users receive the email before the purchase record is fully saved to the database. I believe this might be related to how I'm handling job dependencies. Here’s a simplified version of my code: ```ruby class PurchaseController < ApplicationController def create @purchase = Purchase.new(purchase_params) if @purchase.save NotifyUserJob.perform_async(@purchase.user_id) redirect_to @purchase, notice: 'Purchase was successfully created.' else render :new end end end ``` And the job looks like this: ```ruby class NotifyUserJob include Sidekiq::Worker def perform(user_id) user = User.find(user_id) UserMailer.purchase_confirmation(user).deliver_now end end ``` I've tried using `deliver_later` instead of `deliver_now`, thinking it might help with timing, but the notifications still go out too early. I've also considered using transactions, but I'm unsure how to implement that properly in this case. Am I missing something in how Sidekiq manages job execution order, or is there a better way to ensure that notifications are sent after all related database operations are complete? Any suggestions would be greatly appreciated! This is part of a larger API I'm building. Has anyone else encountered this? This issue appeared after updating to Ruby LTS. Thanks, I really appreciate it!
