Boring Python: dependency management
This is the first in hopefully a series of posts I intend to write about how to build/manage/deploy/etc. Python applications in as boring a way as possible. So before I go any further, I want to be absolutely clear on what I mean by “boring”: I don’t mean “reliable” or “bug-free” or “no incidents”. While there is some overlap, and some of the things I’ll be recommending can help to reduce bugs, I also want … Read full entry -
Recent objects using several Django models
Recent objects using several Django models I released a new Python package which builds on the excellent code published by Simon Willison in the blog post Building a combined stream of recent additions using the Django ORM. The rationale etc. for why this is useful is described much better by him and I’ll save everyone’s time by not repeating it in a worse way. The new package is django-recent-objects, developed on GitHub and available from PyPI. The package supports e.g. combining recent articles and comments in a single activity stream: from testapp.models import Article, Comment from recent_objects.recent_objects import RecentObjects ro = RecentObjects( [ { "queryset": Article.objects.all(), "date_field": "created_at", }, { "queryset": Comment.objects.all(), "date_field": "created_at", }, ] ) additions = ro.page(paginate_by=10, page=1) django-recent-objects adds the following features which aren’t available in the blogpost linked above: The name of the date_field doesn’t have to be the same for all objects Primary keys of different types are1 supported The code uses a real paginator and doesn’t only support fetching the first few objects Hopefully! ↩ -

How I Integrated Zapier into my Django Project
As you might know, I have been developing, providing, and supporting the prioritization tool 1st things 1st. One of the essential features to implement was exporting calculated priorities to other productivity tools. Usually, building an export from one app to another takes 1-2 weeks for me. But this time, I decided to go a better route and use Zapier to export priorities to almost all possible apps in a similar amount of time. Whaaat!?? In this article, I will tell you how. What is Zapier and how it works? The no-code tool Zapier takes input from a wide variety of web apps and outputs it to many other apps. Optionally you can filter the input based on conditions. Or format the input differently (for example, convert HTML to Markdown). In addition, you can stack the output actions one after the other. Usually, people use 2-3 steps for their automation, but there are power users who create 50-step workflows. The input is managed by Zapier's triggers. The output is controlled by Zapier's actions. These can be configured at the website UI or using a command-line tool. I used the UI as this was my first integration. Trigger events accept a JSON … -

Professionalism: What is “professionalism” and why am I writing about it?
I’m starting a new series on professionalism: the set of workplace behaviors that are generally expected at work. These behaviors are largely unspoken, but they do exist: there are consequences for violating them. In this series, I aim to write down some of these rules and explore their implications. Eventually, I hope to have a solid list of what “professional behavior” really means. -

Is my advice too mercenary?
A criticism of some of my writing is that it’s too mercenary. Some see my advice as coldly calculating, too focused on individual outcomes over collective ones, and implicitly distrustful of others. I think this is fair criticism! It’s not exactly what I’m going for, but it’s a fair reading. However, there’s more to it than that, I want to address it (and defend myself, just a little bit). -
Generic Functionality without Generic Relations
When you have some generic functionality like anything commentable, likable, or upvotable, it’s common to use Generic Relations in Django. The problem with Generic Relations is that they create the relationships at the application level instead of the database level, and that requires a lot of database queries if you want to aggregate content that shares the generic functionality. There is another way that I will show you in this article. I learned this technique at my first job in 2002 and then rediscovered it again with Django a few years ago. The trick is to have a generic Item model where every other autonomous model has a one-to-one relation to the Item. Moreover, the Item model has an item_type field, allowing you to recognize the backward one-to-one relationship. Then whenever you need to have some generic categories, you link them to the Item. Whenever you create generic functionality like media gallery, comments, likes, or upvotes, you attach them to the Item. Whenever you need to work with permissions, publishing status, or workflows, you deal with the Item. Whenever you need to create a global search or trash bin, you work with the Item instances. Let’s have a look at … -

Your last one-on-one: what to do instead of an exit interview

You’d never dream of retaliation, are open to feedback – even if it’s harsh. You don’t want to put your departing direct in an uncomfortable or threatening position, but you’d like to know what they have to say! What then? -
Amsterdam python meetup
(Summaries of a talk at the April 2022 py.amsterdam meetup). Interesting takeaways from book 'Test Driven Development With Python' - Rok Klancar The book "test driven development with python" is available for free onine at https://www.obeythetestinggoat.com/ . The subtitle is test driven development (TDD) for the Web, with Python, Selenium, Django, JavaScript and pals... It is a quite thick book, but the author is very enthousiastic about programming and the subject of testing, so it actually very readable. The book consists of three parts: The basics of test driven development and django. So he starts out with explaining web development with django, just enough for having something real to test. Web development sine qua non. He's serious, at the end of part two you'll actually have deployed a web application. (And you'll have tested it, of course.) More advanced topics in testing. The core idea of test driven development is that you first write a (failing!) test and only then you write the code to get the tests to pass. The first test in the book is whether you have installed django (which you haven't yet). That sets the tone for the rest of the book :-) The whole time … -

How to sort case insensitively with empty strings last in Django
Imagine you have something like this in Django: class MyModel(models.Models): last_name = models.CharField(max_length=255, blank=True) ... The most basic sorting is either: queryset.order_by('last_name') or queryset.order_by('-last_name'). But what if you want entries with a blank string last? And, you want it to be case insensitive. Here's how you do it: from django.db.models.functions import Lower, NullIf from django.db.models import Value if reverse: order_by = Lower("last_name").desc() else: order_by = Lower(NullIf("last_name", Value("")), nulls_last=True) ALL = list(queryset.values_list("last_name", flat=True)) print("FIRST 5:", ALL[:5]) # Will print either... # FIRST 5: ['Zuniga', 'Zukauskas', 'Zuccala', 'Zoller', 'ZM'] # or # FIRST 5: ['A', 'aaa', 'Abrams', 'Abro', 'Absher'] print("LAST 5:", ALL[-5:]) # Will print... # LAST 5: ['', '', '', '', ''] This is only tested with PostgreSQL but it works nicely. If you're curious about what the SQL becomes, it's: SELECT "main_contact"."last_name" FROM "main_contact" ORDER BY LOWER(NULLIF("main_contact"."last_name", '')) ASC or SELECT "main_contact"."last_name" FROM "main_contact" ORDER BY LOWER("main_contact"."last_name") DESC Note that if your table columns is either a string, an empty string, or null, the reverse needs to be: Lower("last_name", nulls_last=True).desc().
