Speaking at Python Web Conf
During the week of March 21-25 at Python Web Conf I'm giving my first public conference talk in three years. I'm both excited and apprehensive about returning to the speaker's podium. To me, public speaking is like a roller coaster ride. The climb up the first hill (or minute when it comes to speaking) is absolutely terrifying. Then as soon as the car accelerates (or I begin to speak), endorphins kick in. I go from struggling not to visibly tremble from fear to shaking with excitement. Hint: Use code Speaker15@PWC2022 to get 15% off your ticket costs. The talk I'm going to give is titled, "Confessions of Joe Developer". Here's the synoposis: Over the course of 17 years of professional Python development at Octopus Energy, NASA, and various agencies, Daniel Roy Greenfeld has picked up a lot of easy tricks stolen from the best and brightest in the software community that make him look good in front of his peers and colleagues. And now, at great risk to his career and reputation, he is going to show you how he does it. What that description doesn't tell you is that I came up with the core concepts of that talk … -
Announcing WhiteNoise 6
WhiteNoise is a simple solution to serving static assets. It lets you skip configuring a separate web server for your static assets, and serve them straight from Django. It’s a brilliant tool. I’ve used it for years on various projects, and I’ve recommended it many times, and mentioned it in several blog posts. WhiteNoise was created by Dave Evans in 2013. I’ve met Dave several times at the London Django Meetup. Recently the project’s maintenance was getting a bit backlogged, so I volunteered to help and Dave accepted :) I got to work adding support for modern Python and Django versions, dropping old ones, and merging in a few feature requests. I just released these accumulated changes as version 6.0.0. Nothing drastic has changed for the major version bump - most users should not be affected. setuptools’s python_requires field also ensures users on outdated Python versions still install older WhiteNoise versions. But there are enough changes that it felt like a major number was needed, and version numbers are cheap. Here are the changelog entries for 6.0.0: Drop support for Python 3.5 and 3.6. Add support for Python 3.9 and 3.10. Drop support for Django 1.11, 2.0, and 2.1. Add … -

Save a Django Query to the Database
I found a StackOverflow question on saving a Django query to the database, but I was left super unclear on what to do. There’s all this talk about pickling and serialization that I’m sure makes a ton of sense to someone smarter than me. The current answer is old, however, and in 2022, I found another solution: turning a dict into JSON. Plus, I found a way to make it work with my htmx live search, allowing me to view the results of my query on the front end of my site (read: pretty) to double-check that things look okay before saving. I’ll show you what I did below. I believe pickling still works, so at the end I will show some more thoughts there. models.py - example database structure class Transaction(models.Model): id = models.CharField(max_length=24, primary_key=True) date = models.DateField(null=False) amount = models.IntegerField(null=False) info = models.CharField() account = models.ForiegnKey(Account, on_delete=models.SET_NULL, null=True) category = models.ForeignKey(Category, on_delete=models.SET_NULL, null=True, blank=False, default=None) class Account(models.Model): name = models.CharField() email = models.EmailField() class Category(models.Model): name = models.CharField(unique=True) class Rule(models.Model): category = models.ForeignKey(Category, on_delete=models.SET_NULL, blank=False, null=True, default=None) criteria = models.JSONField(default=dict) # this will hold our query My models store financial transactions, the category the transaction fits into (e.g., … -

How to Set Up Source Maps with Django
Source maps are files that map your minified CSS or JavaScript back to the original code. They allow you to use your browser’s development tools to debug minified code as if it were the original. In this post we’ll look at how source maps fit into Django’s static files infrastructure, including a couple recent changes I made to Django to better support them. We’ll look at using a JavaScript source map, but everything applies equally to CSS source maps. Alrighty, let’s dig in. Directory Layout Let’s look at an example project using source maps to see how they fit into Django’s infrastructure. This project demonstrates a static file setup that works well for most projects. The project has three directories for “static files” with different roles, all in the root of repository: frontend/, which contains the source CSS and JavaScript files. Django doesn’t use this directory at all. Frontend tools, like bundlers, should process the source files in frontend/ and place output files in the next directory, static/. This provides a clear “hand off”. static/, which contains static files for Django to manage. This is in the STATICFILES_DIRS setting: STATICFILES_DIRS = [BASE_DIR / "static"] static_root/, which is created by Django’s … -

Django Rest Framework authentication: the easy way
In this tutorial you'll learn how to implement Django Rest Framework authentication in your web application by leveraging the built-in Django session framework. This approach is way simpler (and secure) than other popular methods such as JWT, and has only one requirement: your frontend (think Vue.js, React, ...) and your backend should be served by the same domain. I created an example project on GitHub you can use to follow along with this tutorial. Table of Contents Why you should avoid JWT for Django Rest Framework authentication Django Rest Framework settings Django Rest Framework authentication endpoint Test authentication using HTTPie A new endpoint to retrieve the user profile Test the user profile endpoint using HTTPie Conclusions Why you should avoid JWT for Django Rest Framework authentication JWT (Json Web Token) is a very popular method to provide authentication in APIs. If you are developing a modern web application with Vue.js or React as the frontend and Django Rest Framework as the backend, there is an high probability that you are considering JWT as the best method to implement authentication. The reality is that JWT is just one method, and unfortunately not the simpler, nor the most reliable. JWT is not … -
Four Tips for Writing Better Go APIs
Go is a really powerful programming language that allows you to write concurrent code that is still easy to understand. But designing APIs can be hard, even for seasoned Go programmers. When designing APIs for libraries and applications in Go it's important to keep in mind the strengths of the language to make your APIs easier to use and avoid pitfalls like goroutine leaks. With that in mind, here are a few common issues I see often with Go APIs and some tips for how to make them better. ## Don't Take APIs Out of Context The context package is a very powerful package that takes some get[...] -

A Problem with Duplicated Mutable Constants
Here’s a small problem I’ve seen where several modules share versions of the same “constant” variable. It came up in the context of a Django project with multiple settings files, but it could happen in different contexts. Imagine you have two submodules defining API_CONFIG as a “constant” dictinoary. The development submodule should copy the value in base, but use a different value for the "rate_limit" key. You have example/base.py which looks like: API_CONFIG = { # ... "rate_limit": "10/m", # ... } …and example/development.py: from example.base import API_CONFIG API_CONFIG["rate_limit"] = "100/m" By importing from base, the development module doesn’t need to completely redefine API_CONFIG. Great - the redundant repetition is reduced. But can you see the flaw in this approach? The problem is that API_CONFIG is the same dict in both modules. The change in development “leaks” back to base: In [1]: from example import base In [2]: base.API_CONFIG["rate_limit"] Out[2]: '10/m' In [3]: from example import development In [4]: development.API_CONFIG["rate_limit"] Out[4]: '100/m' In [5]: base.API_CONFIG["rate_limit"] Out[5]: '100/m' Eek! This happens because Python variables are only names for underlying objects. Pointing another name to the same variable does not create a copy. If this is surprising, Ned Batchelder’s Python Names and … -
