knbk: yep, the parent is an abstract model. thanks!

an abstract model doesnt get created into a table right? its just there for you to inherit from if you want to create a table of your own?

firefox: that's right

hello all... is it possible to annotate a queryset with values from customized model methods? ie I have Team(Model) with get_jobs(self) method which returns a qs of related WorkOrder(Model) objects.. and I want to annotate counts of these querysets .... (trying to minimize db queries) ... i can post my code if it helps

drvid, no, you can only use ORM tools or fallback to raw SQL

thanks for confirming GinFuyou

Counting related objects should simple enough though

should be.. its related through two M2M tables

just easier to write as model methods right now

If you dpaste your models and what you want to get from them somebody may give you a hand with query

Not me today though, tired

np sounds fair :)

Hi, I'm having some trouble deploying a Django 2.1 app to AWS EB

I'm trying to configure a postgresql database. In my .ebextensions/ config file I have "postgres95-devel: []" in my yum packages, and psycopg2==2.7.5 in my requirements.txt

however whenever I deploy I get django.core.exceptions.ImproperlyConfigured: settings.DATABASES is improperly configured. Please supply the ENGINE value.

the ENGINE value is 'ENGINE': 'django.db.backends.postgresql',

any ideas?

that's a wrong engine I think

that would be correct, it's just that it isn't the actual value being used

what?

I've got an app deployed to a staging environment; how do I debug an issue with signals on the staging platform? E.g. see any errors that may be thrown

that's the engine specified in the 2.1 docs for postgres

that value for ENGINE is correct, but you have some other misconfiguration, and it's not used

i'm not sure what you're talking about

Yeah, that's right, sorry, I was keeping outdated name ^_^"

wait I think I see it. I set "DATABASE" instead of "DATABASES"

if that's the issue i'm gonna be a little upset.. been trying to figure this out for 3 hours

that was it. fml

lukebord: it happens to the best of us :P

I have a website where I want the users to have a list of privately stored notes that only they can access. I currently have a Model for my note that just holds a single TextField.

I want it so that when the user accesses the home page, they see their notes. Unfortunately, I don't really know any way to bind the notes to a specific user.

does the note model also have a foreign key to User?

that would be the easiest way

FunkyBob: ah, yes, that is the easiest solution. I'll try that out first.

is the compiler and interpreter part of the venv?

firefox: you mean "python"? yes

so if you have 2 venvs, each has a compiler and interpreter?

firefox: we usually don't refer to a compiler, but yes

in python we don't tend to talk about a "compiler"

since it's built into the interpreter

what compiles the source code to byte code then

when you create a venv, there's a bin dir in it with a patched copy of python

22:04 <+FunkyBob> since it's built into the interpreter

python is patched now?L

is there anyway to see the byte code after it gets compiled

firefox: the dis module

firefox: if you want to learn more about the stdlib, read pmotw

FunkyBob: so currently, I have this : https://dpaste.de/kJrV (yes, I realize it's silly to use a ModelForm when it's only got two fields)

FunkyBob: but this is causing me to have a single dropdown box with the current user's name in it, which is really pointless.

no, it's not silly at all

so processors can't read python byte code? it has to run through the interpreter first which then makes it readable to the processor?

firefox: it's executed on a vm

(for cpython)

(and jython and ironpython)

(or whatever runs on dotnet these days)

FunkyBob: wait a second, it's actually showing all the users instead :(

redrapscallion: yes, omit the user from the form...

firefox: no, the interpreter interprets the bytecode..

only tools like PyPy will compile it to actual machine code

but the interpreter still makes use of the processor right?
