is order.items cleared, or order deleted, or order.item just has itemA, itemB, null, or still has itemA, itemB, itemC, but itemC references a null object?

blackcross: it depends on how you configure your models

I believe the default is on delete cascade

so it deletes the whole order object? O)o

might. What you probably want is a state column on the items - so you don't delete but set them to unavailable

No, there's no cascading for M2M's.

and perhaps set the on delete clause to 'prevent'

ahh OK

so it would only remove the item line from order but not the whole order

still wrong but...

mattmcc: so to be clear, the items' list would just have a null reference in it somewhere?

It should remove that record from the intermediate table.

Remember, an M2M is just an extra table with FKs to each side of the M2M relationship.

ok, ty

Okay. I'm back. Sorry for the delay.

anyone ever get "DatabaseError: SSL error: decryption failed or bad record mac"?

im setting up a new server, and i have postgresql, and im getting that when running a celery job

Koterpillar: I've got my B model, which has foreign keys to A and C.

I'd like to return the unique A's along with how many C's are under each A.

B is not registered as a through table.

I guess I should do distinct on C, then.

But that won't properly roll up the A.

Ehr. Other way around.

A.objects.annotate(c_count=Count('b__c'))?

Tried it. :(

Only getting back one A object.

Oh. Oooooh.

Our database team is fucking with the database.

So most of the records are missing. :I

That's why I'm only getting one.

Disregard. User error.

im a decently experience python user about to get started with django

is pycharm my best bet for an IDE?

Omega037: I really like pycharm as a python IDE :)

Omega037: i personally don't use an IDE, so you can use whatever you used before

PyCharm is suppose to be good however

moldy: Sorry, had to attend to dinner. Here is an example: https://gist.github.com/jessamynsmith/75ac9febf...

Omega037: I'm a big fan of PyCharm.

i normally use jupyter for prototyping

and pycharm for serious development

Omega037: use whateVer you are famIliar with

i only have the free version though

well, i didnt know if there were good ones for django

like im going to first build a CRUD application

some forms and a postgres backend

Django's just Python.

well, its web based

mattmcc: and <s>magic</s>metaclasses

but if you guys all think pycharm is solid, then good

is it worth my buying a license?

PyCharm does have specific django support

(in the paid version)

Omega037: If you're a student, pycharms is free

I mean you can set up intellij to do just about everything pycharm does, but it's work

umm, im not a student

I've got it , personally I find it a little clunky/slower on osx to Sublime which I'm used to

i could get work to pay for a license, but im not gonna ask unless i really need it

i was on a macbook, but i got fed up and moved back to a lenovo

Omega037: Lenovo on Linux?

no

I thought MS sent tactical nukes to people still on Win7 these days.

Ah, right.
