implementing ActiveRecord callbacks and background processing in Rails 7.1
I tried several approaches but none seem to work. I've looked through the documentation and I'm still confused about I've searched everywhere and can't find a clear answer... I'm working with an scenario with ActiveRecord callbacks not behaving as expected when used in conjunction with background processing jobs in Rails 7.1. I have a model called `Order` that triggers a background job to send a confirmation email after it is created. I am using the `after_create` callback for this. The question is that the email is being sent multiple times for the same order under certain conditions. Here's a snippet of my model: ```ruby class Order < ApplicationRecord after_create :send_confirmation_email def send_confirmation_email OrderMailer.confirmation(self).deliver_later end end ``` I've verified that the job is being enqueued multiple times, which I suspect is due to some race condition where the `after_create` callback is triggered more than once. I've tried adding a unique constraint in the database to prevent duplicate entries, but it doesn't resolve the scenario since the duplicates seem to originate from the callback itself. Additionally, I checked the job processing logs and noticed that the same order ID is getting picked up multiple times: ``` Performing OrderMailer.confirmation with arguments: [#<Order id: 1, ...>] Performing OrderMailer.confirmation with arguments: [#<Order id: 1, ...>] ``` Has anyone encountered a similar scenario, or does anyone have suggestions on how to handle this scenario effectively? I would appreciate any insights on best practices for using callbacks with background jobs in Rails 7.1, especially related to ensuring that the job is only enqueued once per order creation. My development environment is macOS. What's the best practice here? This is my first time working with Ruby 3.9. What's the correct way to implement this? This is my first time working with Ruby 3.10. I'd really appreciate any guidance on this.
