PostgreSQL: Full text search with the “websearch” syntax
PostgreSQL’s powerful full text search feature supports several query syntaxes. Of these, a website search feature should typically pick the websearch syntax. websearch copies some features from popular search engines, as covered below, offering familiar short syntax to users. It is also forgiving and will never raise a syntax error for user input, whilst other syntaxes can. The syntax The websearch syntax discards stop words, such as “a” or “the” in English, then parses according to these rules: Individual words match independently. Double-quoted phrases match as a single unit. The word or (case-insensitive) specifies an “or” condition between two words or phrases. A - prefix specifies to not match the following word or phrase. The below table gives some examples mapping queries to their tsquery representations. Query tsquery Notes the donkey 'donkey' Stop word “the” removed the blue donkey 'blue' & 'donkey' The two words can appear in any order, with any number of words between "blue donkey" 'blue' <-> 'donkey' The words must appear together in the given order "the donkey" 'donkey' Stop words are removed within quotes donkey or mule 'donkey' | 'mule' Either word will match "blue donkey" or "red mule" 'blue' <-> 'donkey' | 'red' <-> … -

Boost Your DX bundle deal update
My two “Boost Your DX” books are available in a bundle deal, saving $10 compared to buying them separately. Great for improving your Django and Git skills at the same time. Buy the bundle on Gumroad This offer does not apply to team licenses. I initially created a bundle deal in October, shortly after releasing Boost Your Git DX. However, it was done with a “hack” using Gumroad’s upsells feature, meaning you had to try to buy one book first to see the offer. This option was less discoverable and didn’t stack with the regional discount for lower-income countries. On Christmas day, Gumroad released a true bundle feature. I have taken advantage of this to create the bundle product page. Enjoy buying for yourself or gifting to others, and let me know if you encounter any issues. May your developer experience always improve, —Adam -

Django: Detect the global privacy control signal
Global Privacy Control (GPC) is a specification for web browsers to signal website operators not to share or sell the user’s data. This signal is intended to exercise legal data privacy rights such as those provided by the California Consumer Privacy Act (CCPA) or the EU’s General Data Protection Regulation (GDPR). While GPC is a proposal, support has been implemented in Firefox and several other privacy-focused browsers and extensions. The GPC C specification is deliberately simple to implement with only a few moving pieces. Everything is covered in the implementation guide and demo site. In this post, we’ll look at implementing GPC within a Django project with code samples you can adapt. Because GPC is simple but requires very situation-dependent actions, it would be hard to build any specific support into Django or a third-party package. The GPC signal (sec-gpc header) When enabled, the browser sends a sec-gpc header with a value of 1, known as the GPC signal. It’s up to your site to save that the signal was seen for the user and act accordingly, depending on applicable regulations. You can check the header in a Django view like so: def index(request): ... gpc_enabled = request.headers.get("sec-gpc", "") == … -

Weeknotes (2023 week 50)
Weeknotes (2023 week 50)django-imagefield The path building scheme used by django-imagefield has proven problematic: It’s too likely that processed images will have the same path. I have changed the strategy used for generating paths to use more data from the source; it’s now possible (and recommended!) to set IMAGEFIELD_BIN_DEPTH to a value greater than 1; 2 or 3 should be sufficient. The default value is 1 which corresponds to the old default so that the change won’t be backwards incompatible. However, you’ll always get a deprecation warning if you don’t set a bigger value yourself. The default will probably change in the future. Advent of Code I have always felt a bit as an imposter because I do not have any formal CS education; not so much in the last few years but certainly earlier in my career. I have enjoyed participating in the Advent of Code 2022 a lot and I have definitely learned to know when to use and how to use a few algorithms I didn’t even know before. I’m again working through the puzzles in my own pace and have managed to solve almost all of them up to today this year. There still are some … -
