pacebrian0: how about self.probe.updatecals()

ah nevermind, even if it works, it will be a bad idea in my case :P

pacebrian0: and self.num? where is this defined?

shangxiao: 1st bit didn't work, basically i tried to call an instance in probe but I screwed up badly. I want num to be the serial (PK) of the instance i want to change

well doing it that way is incorrect

create a new probe, save it, assign it to calibration, then save calibration

or if probe already exists, just update the data

also, you should capitalise your class names

you really need to look at running flake8 on your code :)

yay flake8

also, yay landscape / prospector

Guys I have this form: https://cdn.pbrd.co/images/2igltIFq.png I'm doing autocomplete form with AJAX. Normally I just send 'Employee' input.text().

But this is wrong way, because I need their ids

so my question is how to get form data without submit?

jquery.serializeArray() can apparently do that

shangxiao: this is my Ajax function https://dpaste.de/4tWu

shangxiao: if I do that, I will run into the same problem when I assign. Is there any way I can access a particular instance inside the same class, like an instance where the passed serial number is the same as a particular instance?

Im not sending data to TaskCreateForm, but to a function

pacebrian0: i'm having trouble understanding what you want to do

firstly stop using the word serial :)

just say pk if that's what you mean

or id

and if you want to access an instance of a model, you need to use <Class>.objects

not sure if self.objects is a thing, never tried

shangxiao: in my calibration class, I call a function in the probe class, passing in a FK of the probe class and a date to be updated. In the probe class, I want to get the instance where the FK I passed is equal to the PK so I can update the date. P.S. sorry for the serials :)

shangxiao: so basically, var=probe.objects where PK==FK ?

shangxiao: self.objects is explicitly not a thing; it'll raise an exception saying you can't access the manager from an instance

though you can do self.__class__.objects which achieves the same thing.

How can i install virtualenvwrapper with python 2.7 ?

hi

I'm using circus + chaussette (with nginx), if I set some env in circus.ini, how can I read them in my settings.py?

Fisiu: presumably the way you would with any other environment variable

(though you may find https://django12factor.readthedocs.org/ etc. useful)

doismellburning: os.environ.get should work then? thanks for url

Fisiu: assuming "set some env in circus.ini" means "setting environment variables", yes

(I've no idea what circus/chausette are)

chaussette is a wsgi server while circus is a process and socket manager

hello, how do I get_xxx_display() from instance in post_save for my model ?

when I do instance.get_xxx_display() it prints key instead of value

I have tuples in my Model

like (1, "new task")

it prints 1

instead of new task

dpaste code and any error or output

this is my model

this is output email

I … hmmm.

Hi everyone! I trying to sort my list of products (in the admin panel), in alphabetic order. That is the best way to do that? Thx!

Silvering: set the ordering attribute on your modeladmin?

hi

kezabelle: Ok thanks I try

in a project I have a custom User model and since I will need to use the same model in another project, I'm trying to extract it from the main project and make it a library. I've never done this before (I mean, extracting a UserModel into a separate library). I was wondering if there is a particular way I should structure my library project to make it testable (as in unittests) without having to import the library into a full Django project. Are

there any example of this I can give a look at? Thanks
