eccentric_j: something like OnboardingVenue.objects.filter(user__groups__company__merchants__isnull=False, is_active=True)

I had to mess a little with models, so that related expression may need tweaking

Oooh that still gives me a really good direction to go in. Thanks very much for wrestling with it!

:)

why in django does a choices field have a short version to be stored in db...what is the benefit of that

YEAR_IN_SCHOOL_CHOICES = (

('FR', 'Freshman'),YY

eblip: It gives you options, like supporting legacy database systems, or minimizing storage space.

in general it's a good idea to separate what's stored from what's displayed

ah ok, i can see it saving a little space..but when you display the details...you will be displayed FR

rather than Freshman, and this may be confusing for someone who doesnt know about these matters

depends how you access it

if you use a default modelform, it'll use the display name

(unless you override it)

A select HTML element works similarly `<option value="10">Freshman</option><option value="11">Junior</option><option value="12">Senior</option>`. The idea is you can use labels your users recognize that powers data you can work with

you can access the display name yourself with get_<FIELD_NAME>_display()

ah cool... ill try that

some discussion here: https://www.reddit.com/r/django/comments/4w051c...

what's a good approach on using atomic transactions, while using a post save signal?

thanks ill take a look at that

ironi: I'm not sure you can... I think if you want atomicity you might need to look at overriding the save() method

i.e. I create model Foo and then 2 instances of model Bar with fk to model Foo, within a transaction.atomic block - and then I want the post save for Foo to be emitted after theentire transaction is done

jessamynsmith: is maybe transaction.on_commit(lambda: signal_receiver(foo.id) the way to go instead of using post_save signals?

ironi: I feel like we need somebody more versed than I in the intricacies of django and transactions

maybe knbk

and then get the instance from the db with a select_related(Bar)

I would like to avoid doing another request bound db query though

is there a 'legal' way to get say uptime/disk space usage within a django app?

ask your os?

FunkyBob: yeah, obvs, but was wondering if there was a particularly standard way to do it.

hanetzer: no. the most standard way would be to assume there is no such thing

moldy: gotcha.

I have a weird problem. I have an app created by django 2.1 and the models have the view permissions, but one created with 2.0 does not and both live on the same project. Is this a knows bug or something?

hanetzer: also, uptime and disk space usage are **very** different things. which real-world problem do you want to solve?

moldy: recreate daloradius in django. so, hopefully getting feature parity

they have it, so I was wondering about it myself.

calling it djaloradius for now :)

hanetzer: not familiar with daloradius. sometimes the best thing to do is not to do something.

yep. just idle curiosity, as that wouldn't be crucial to the operation of it

'authdate timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP' how would I go about this?

Is get_absolute_url() still useful if your views are served over API's and you have a completely decoupled frontend?

you might still want to produce links in the API

sounds good

https://ptpb.pw/65PU.png << this sort of layout, what term should I google to learn how to make something like this?

home/management/reports/accounting... each have a main section and subsections, which I think would all be called a 'view' in django

I would suggest starting here: https://www.djangoproject.com/

hanetzer, nav bar you mean?

is that what that's called? I'm not a native web dev

when i use git do i need to push all the migration files? theres tons of them

firefox: yeah. think they could makemigrations themselves but it strikes me as part of the codebase, as opposed to stuff like Makefile and Makefile.in when using autotools (which you supply a Makefile.am to)

hanetzer, well, that part you mean? https://www.w3schools.com/Bootstrap/bootstrap_n...

do you know what DS_Store file is/

?

is not it something Mac, firefox?

firefox: by cargo cult, some kind of mac thing

something you want to add to your global .gitignore ;)

oic

firefox: yes, you should commit all your migration files. migration files are code.

firefox: mac thing. basically something like Thumbs.db on windows

GinFuyou: yeah, that looks rightish.

this .DS_Store file is everywhere wtf

yep. and all your zip file have something called a 'resource fork' in them. __MACOS__ with subfiles
