What's the best thing about working for Octopus Energy?
On November 16, 2020, I started my first day of employment at Octopus Energy. Here's why I love working there. The Tech Stack The entire tech stack is built on things I know. Python, Django, AWS, and modern JavaScript frameworks. It's been implemented in a very solid way, managing to be both conservative in approach yet innovative in design. While my previous experience has proven useful, I've had the chance to learn new and exciting things. Examples of things I've learned: Hashistack on AWS React & Next.js Yet when I think about it, the tech stack isn't the best thing about working for Octopus. I can find the same tech stack in a thousand other organizations. The People It's always a delight to work with bright, positive-minded people who share your excitement for a job or cause. I like being around people who know things I do not, for no other reason than I can learn by osmosis. I enjoy being around them, and can't wait to meet them as the pandemic fades away. I also am amazed by the same treatment across different groups within the organization. No group or division is looked down on, be they software engineering, … -

One Database Transaction Too Many
Have you ever wondered how bugs are born? I'm not talking about the trivial kind you can catch with simple unit testing. I'm talking about bugs that may not be apparent on first sight, but are so obvious in retrospect. This is a story about how I accidentally sent hundreds of users messages they got paid when they didn't! What it feels like when you realized you made a mistakeIllustration by Milica Vezmar Basara Table of Contents The Story Creating a Payout Sending Notifications Working in Bulk The Bug Nested Transactions Remedies Assert Atomic Block Durable Transaction Sending Signal on Commit Using a Queue Testing Testing with Django Testing with Pytest Thoughts on Django Signals The Story We have a process in the system where we pay out money to merchants and other types of users. The payout process is a pretty big deal for most users because this is how they get paid. Creating a Payout To facilitate the payout process we have a Django model called PayoutProcess. To create a new payout we use a function that looks roughly like this: from __future__ import annotations from django.db import model, transaction as db_transaction class PayoutProcess(models.Model): #... fields @classmethod def … -

Backend Engineer Interview Script
Dwight Schrute, Assistant *to* the Regional Manager. Dunder Mifflin Inc. Credit: NBC. Last month I’ve written a post with Django-specific interview questions. That post is about verifying a candidate’s depth of knowledge with Django. This post is about less specific questions I ask a candidate. Before proceeding to the Django specific ones. If I do proceed after all. In case the candidate does not have any Django-specific experience, what’s the point? These questions do not look for specific answers. Rather the aim is to open up a discussion. So the questions are more in the form of how or why rather than what. And no. How do you describe yourself? is not one of these questions. If you ever get that question, the only correct answer is that by Dwight Schrute as shown above. The questions in this article revolve around: improving web application response time designing authentication handling asynchronous work / task queues HTTP REST API design 1. Server response time Q: In the context a dynamic “data driven” web application, how would you decrease a page’s response time? Asking this should allow the candidate to come up with multiple answers. Among the common answers you should note the … -
How to test a Django ModelForm
What is a ModelForm in Django? ModelForm in Django is a convenient abstraction for creating HTML forms tied to Django models. Consider the following Django model: from django.db import models from django.contrib.auth.models import User class Invoice(models.Model): class State(models.TextChoices): PAID = "PAID" UNPAID = "UNPAID" CANCELLED = "CANCELLED" user = models.ForeignKey(to=User, on_delete=models.PROTECT) date = models.DateField() due_date = models.DateField() state = models.CharField(max_length=15, choices=State.choices, default=State.UNPAID) def __str__(self): return self.user.email To create a form for this model so that we can save and edit invoices in a view, we can subclass ModelForm as follows: from django import forms from .models import Invoice class InvoiceForm(forms.ModelForm): class Meta: model = Invoice fields = ["user", "date", "due_date", "state"] Here we create an InvoiceForm tied to Invoice. This form will expose the following fields in the form: user date due_date state Once we create a ModelForm, we can use it in creation/editing Django views. For an example of the usage, check out the documentation. In this post we focus only on testing the form without interacting with the view layer. (For an example test of a form in the context of a view see Testing an inline formset in Django) How to test a Django ModelForm Testing the … -
