Setting tags in your fastapi endpoints will group them in the docs. You can also set some metadata around the tags to get nice descriptions.
Here is a full example from the post.
I often want to reach for non existing list comprehensions in jinja 2, Here are a few nice equivalents.
DataDog ddqa is building out a textual app and deploying it with pyapp. They have CI setup to fully build and cross compile their textual tui into github releases that you can just download from their releases page. This is something I am looking at for markata. This would be pretty sweet to be able to make it just work on places like windows. It would also be interesting to try to build a full desktop app with pyapp.
Today I am working on fokais.com, trying to get to a point where I can launch by workig through stripe integrations. This is my first time using stripe, so there has been quite a bit to learn, and I am probably building in more than I need to before launching, but I am learning, and not in a rush to launch.
I am building the fokais backent in python primarilyt with fastapi and sqlmodel on sqlite. My billing integration is going to be all Stripe.
Here is a link to the stripe docs for your refrence, especially if you want to see how to cancel subscriptions in other languages. They include code samples for many popular languages.
This is the part of the user model that includes the cancel and reactivate methods. It pretty much follows the stripe guide.

Looking for a Heroku replacement, What I found was shocking!

I’ve long hosted my personal blog as a static site on waylonwalker.com. It’s all markdown, converted to html, and shipped as is. It’s been great, I’ve moved it from GitHub Pages, to Netlify, tried Vercel for a minute, and have landed on Cloudflare Pages. Each migration has not really been that hard, it’s just pointing ci to a different host after the site has built.
Now the part that I have struggled with is how to cheaply host a server rendered application that can just live on forever without me paying for it. This is a harder problem as it costs more to keep servers spinning, memory, and disk all ready for you to use at a moments notice.

Litestar is an interesting api framework similar to fastpi, that I am interested to check out to see if it fits into some project scope. It sounds like it comes with a lot more batteries included for things like auth, but does not have hard opinions like django. At this point I’m not jumping off of fastapi, but its something I want to try.
I wanted to host some static files through fastapi. Typical use cases for this might be some static web content like html/css/js. It could also be images or some data that doesn’t need dynamically rendered.
The docs cover how to host static files, and give this solution that is built into fastapi.

I’ve recently given tailwindcss a second chance and am really liking it. Here is how I set it up for my python based projects.
https://waylonwalker.com/a-case-for-tailwindcss
npm is used to install the cli that you will need to configure and compile tailwindcss.
npm install -g tailwindcss-cli
Setup #
You will need to create a tailwind.config.js file, to get this you can use the cli.

Fastapi lets you tag your APIRouter’s so that the swagger docs are grouped according to the router.
router = APIRouter(tags=['router'])
Now all routes in router will appear in the router group in the swagger docs.
sqlite-utils is primarily a cli tool for sqlite operations such as enabling full text search, and executing searches, but it also has a nice python api that is exposed and pretty straightforward to use.
from sqlite_utils import Database db = Database("database.db") db["post"].enable_fts(["title", "message", "tags]) db["post"].search("water")
This returns a generator object that you can iterate over the row objects with.
datasette really does everything doesn’t it!
> A command-line utility for taking automated screenshots of websites
Daaaang, this is such an elegantly simple way to get web screenshots with a cli. I was literally up and running with two commands on my arch linux machine (which it warned was unsupported by playwright).
pip install shot-scraper # Now install the browser it needs: shot-scraper install shot-scraper waylonwalker.com shot-scraper https://datasette.io/ shot-scraper https://datasette.io/ -h 1280 -w 1920 shot-scraper https://datasette.io/ -h 480 -w 720 shot-scraper shot --selector '#posts' https://thoughts.waylonwalker.com/post/89
Note
shot-scraper https://datasette.io/is a full length screenshot of the entire page.Oh and its pretty dang fast, let alone the setup time, this crushes on startup time in my attempts to use a headless browser in the past.
An interesting way to build automatically annotaatd docs with arrows pointing to elements on a webpage.
Creating many to many relationships with sqlmodel requires a LinkTable Model. The link model will keep track of the linked id’s between each of the models.
I went down the route of leveraging the json-enc extention in htmx, but later realized that this completely breaks browsers/users who do not wish to use javascript. While most of the web would feel quite broken with javascript disabled, I don’t want to contribute to that without good reason.
Taking a second look into this issue, rather than using json-enc, and using as_form to get form data into a model keeps the nice DX fo everything being a pydantic model, but the site still works without js. with js htmx kicks in, you get a spa like experience by loading partials onto the page, and without, you just get a full page reload.
