Sending Emails For Successful Web Scraper Results Discussion

It took me some time to understand why my ActionMailer::MailDeliveryJob were getting enqueued but not performed when running the rake task. Reading this article https://stevechanin.blogspot.com/2017/05/deliverlater-not-working-in-rake-tasks.html it seems that using UserMailer#deliver_later puts the job in a memory queue that dies when the rake task ends.
Using UserMailer#deliver_now or putting the rake task to sleep with a sleep(5) at the end of it does help for now.

Restart the terminal, and then execute the rbenv command. The list of commands ought to be included.

If you're getting an error of "no .page method for nil Object" reset your Rails server. I was debugging in the error page console and saw that no params were being passed through, but once I restarted my Rails server everything worked perfectly.

How did open_letter receive your email with deliver_later? I had to switch to deliver_now on the notify method for this to work.

Update: If you want to user deliver_later in development, you can try the Solid Queue gem.

If you don't want to add the gem but want to test out open_letter, you can user deliver_now or add sleep to the end of the notify method as the other user suggested.
