♦️ There is a safer alternative to 'git push --force'!

🫸 Use --force-with-lease and --force-if-includes to restrict force pushes so that they don’t unintentionally overwrite commits pushed by others.

Explained in my post: https://adamj.eu/tech/2023/10/31/git-force-push-safely/

I finally got around to upgrading my main project from Django 4.2 to Django 5.

I allocated several hours this evening for the arduous process of making sure I got everything right, and before I got started I figured I'd give django-upgrade (by @adamchainz) a try this time around.

No more than 15 minutes later my project was running on Django 5, tested good, and pushed to production.

Wait, what?!?! 😲

Super impressed with how easy django-upgrade made it ❤️

@jack Great to hear.

Which fixer was the most helpful? There are none for Django 5.0 but maybe the 4.1 or 4.2 ones fixed some deprecations that you hadn’t addressed…

@SebastianM6L@mastodon.social avatar

Why isn't

Model.objects.get_or_none()

a thing in ?

That would save some boilerplate code or am I wrong?

Because if there is a chance that there is no entry for the query get()will raise a DoesNotExist exception that you have to catch.

get_or_none()would be cleaner in my opinion.

@SebastianM6L Many duplicate closed tickets asking about this:

https://duckduckgo.com/?t=ffab&q=site%3Acode.djangoproject.com+get_or_none&ia=web

Also, I’ve seen several packages implement it. I think it could be a worthwhile forum discussion, at laest to gather more opinions. I suggest you start a thread on https://forum.djangoproject.com :)

I’m helping a client upgrade to django-import-export v4, and I gotta say I’m enjoying the clarity of the release notes. Every breaking change spelled out, with PR links. Thank you Matt :)

A pattern I’ve recently enjoyed using:

  1. Change some function in a way that needs fixes to call sites.
  2. Run the whole test suite with pytest.
  3. Copy the list of failing test IDs from pytest’s summary into a scratch file.
  4. Fix up the found callers.
  5. Verify everything fixed by saving the list of tests with: pytest $(cat scratch/testids.txt)

adamchainz,
@adamchainz@fosstodon.org avatar

@watte Yes, and allowing partial test runs in step four whilst fixing up certain callers.

What's the lowest amount you've paid for something using a credit card?

Went to the market the other day and paid for a £2 punnet of fruit using a credit card. Guy was running Square on his phone, showed me the screen, I tapped, done.

I remember when everyone was £10 minimum for card payments, even in large shops. Now sole-traders can take instant payment for low value amounts. Brilliant!

@Edent I regularly go in Tesco and buy a single banana for my toddler at 27p.

@OliverC @alexhern @Edent This is a small local supermarket, they’re cheaper in larger ones. I always thought produce was more expensive in the US, I saw broccoli at $5 in a large supermarket, some years ago.

Trying to upload a directory and use webkitRelativePath to preserve the local path in a app, and it seems like that might not be so easy.

I've tried a custom upload handler, but even there, Django seems to have already stripped the path.

adamchainz,
@adamchainz@fosstodon.org avatar

@circumeo Did you get any further? Sounds like an interesting feature to support, though we’d probably wait for the cross-browser spec to add it to Django itself.

adamchainz,
@adamchainz@fosstodon.org avatar

@circumeo Ah, looking at the docs, this is an HTML input property, only: https://developer.mozilla.org/en-US/docs/Web/API/File/webkitRelativePath . I think Django isn’t stripping the path, it’s just not sent by the browser. I think you need to use JavaScript to put the values into some form field if you want to send them to the server.

adamchainz,
@adamchainz@fosstodon.org avatar

@circumeo Ah I see. It is probably up in the WSGI later, and may even be a recommended step in HTTP or WSGI servers. Deserves more research.

Any #django cracks here who can explain me why when I run my tests with the django built in manage.py test (runs unittest) I have 51 tests run.

When I run them with pytest It will only run 38 tests.

I'm really enjoying this post by @capjamesg about fun things you can do on your personal website: https://jamesg.blog/2024/02/19/personal-website-ideas/

After many years of thinking about it, I finally created my own site 2 months ago and it's been a lot of fun. I'd definitely recommend it!
