Coming back at update_or_create for round 2!

If you call update_or_create where the instance already exists and the defaults passed in are already the values on the instance, do you ever want it to actually re-save the instance?

I'm running into the case where I'd prefer it to not update the instance if it doesn't need to. I'm guessing I'm overlooking some race condition problem though.

@fallenhitokiri That would be a tough one. I'd argue that since nothing else is being updated, you wouldn't want that timestamp being touched.

CodenameTim,
@CodenameTim@fosstodon.org avatar

@fallenhitokiri And that's probably the nail in the coffin for the argument to change it.

BUT.

I'd argue the savings of not issuing an update > the heartbeat example. Especially considering you could replace it with update_or_create(id, {'updated': timezone.now()}) whereas you have to re-implement update_or_create to get that performance optimization.

@webology I'm realizing that this problem is only a major problem when using django-simple-history where it creates a historical record on every save. These empty saves add up if they occur on a regular basis.

CodenameTim,

@fallenhitokiri I see two reasons for the updated timestamp column. One is for a heartbeat like you described. The other is for a last modified. In that latter case, if nothing has been modified, it's more confusing to have that timestamp changed.

@ryanhiebert @webology Welp, maybe I should create that issue on the repo for a library specific utility function.

@ryanhiebert @webology Pretty sure bulk_create with update_conflicts is an upsert for postgres now.

Open source contributors, what did you wish you knew when you started contributing? Or is there something that kept you from contributing for too long?

I am asking for a presentation, which I will give in two weeks.

CodenameTim,
@CodenameTim@fosstodon.org avatar

@mahryekuh smallish, regular contributions go a long way.

CodenameTim,
@CodenameTim@fosstodon.org avatar

@mahryekuh For me it was the idea that small changes didn't make an impact, so it wasn't worth the high effort to get started and do them.

When having a #Django App deployed to #fly.io @flydotio what's the best way to read the actual Django logs? Store them in volumes? Or stream them to some S3? I get a 500 response in the browser sometimes and want to see the actual stacktrace.

@derwaro Have you considering installing Sentry?

Wrote about cracking the case of the missing time zone data. Where did it go? Did I cause it or was it an upstream bug?

(Spoiler: it was me..)

@josh Yikes, that's a gnarly one to untangle. Nice write-up!

I laughed at:

All right, here's a fun Django question:

You start a simple project, using SQLite locally. You write a model, then call makemigrations, then call migrate.

At what point is the db.sqlite3 file created?

CodenameTim,
@CodenameTim@fosstodon.org avatar

@ehmatthes I would have assumed migrate, but I'm guessing makemigrations because it needs to check the django_migrations table to determine which migrations have been applied.

After a month and a half of working nearly full-time looking for a job, I accepted an offer today.

I'm worn out and looking forward to a little time off before I start something I'm better at. 🙂

@_chrismay Congratulations Chris! That's always a challenge and a relief.

@nanorepublica I think there's room for this. While applications shouldn't have this (it assumes some level of lack of data integrity), it's probably in most systems > 5 years old. I look at this as a data driven version of https://deadmanssnitch.com/

I was just reminded of the most difficult language I had to learn. https://en.wikipedia.org/wiki/VHDL

Looking at it now, I get more of it, but trying to learn that syntax at the same time I was learning Java was challenging.

CodenameTim,
@CodenameTim@fosstodon.org avatar

@immibis Well then. I'm glad I'm not a Verilogger!

Edit: Not that there's anything wrong with Verilog. The syntax is unusual the point of being obscure to an uninitiated person.

@CodenameTim@fosstodon.org avatar

@immibis You're illuminating massive blindspots of mine from college!

CodenameTim,
@CodenameTim@fosstodon.org avatar

@immibis I barely understand what a simulation language is today. Much less so when you remove 16 years of programming knowledge.

@satya Actually learn VHDL 😅

Thinking about this:

> Django apps should use as little code as possible; they should lack boilerplate. Django should take full advantage of Python’s dynamic capabilities, such as introspection.

My test suite has just one dot on the last line. What would you do?

  • Delete one test
  • Change the width of the terminal
  • Keep it as a visceral reminder of the uncomfortably chaotic nature of the universe
  • Write more tests

@dabeaz @nedbat That's the best idea I'll see all week 👏

@joni how does that room feel when there isn't bright sunlight? I want to paint my office a bold color, but I'm afraid it'll be overly dark when it's not bright out.
