Pizza Recipe

Hi I'm Simone! This recipe was developed based on some tips I acquired over time from lots and lots of resources and tutorials like youtube videos, family and friends recipes. I'm just an amateur who likes making pizza :)

If you plan to perfectionate your pizza making skills, I suggest to come up with your own recipe and research online watching lots of tutorials and different techniques. For now the following recipe is the one that works for me!

(I'm not a professional pizzaiolo and I never had any sort of experience in a professional pizzeria restaurant)

Introduction

To get rq workers talking to opbeat at this current time, you must use a custom rq exception handler and add it to the chain that the worker accepts. This allows us to call opbeat synchronously and avoid the current issues with the opbeat library's async workers.

Both of the examples below keep the original rq exception handler functionality of moving a failed job to the failed queue, but this is optional - if you only want opbeat logging then just don't pass the move_to_failed_queue handler.

Note that we send a lot of extra information about the job itself (see _get_job_details) but this is not a requirement, the stack you get is useful enough without it.

With django-rq (>=0.9.5)

Probably one of the easiest things you'll ever do with gpg

Install Keybase: https://keybase.io/download and Ensure the keybase cli is in your PATH

First get the public key

keybase pgp export | gpg --import

Next get the private key
