Import python file in Django models

Question

I have a question about importing python file from Django models. I'm just creating a models form and I have in this one a list of country. The user can make a choice with a list.

But in my models.py file, it's very ugly and I would like to know if it's possible to write the country list in a python file and call this file in the argument choices = COUNTRY_CHOICE

This is my models.py :

#-*- coding: utf-8 -*-

from django.db import models
from django.forms import ModelForm

# Sexe choice

CHOIX_SEXE = (
('M', 'Mâle'),
('F','Femelle'),
)

CHOIX_PAYS = (
('AFG','Afghanistan'),
('AF','Afghanistan'),
('ZA','Afrique du Sud'),

I assume I need to create a python file, write the list of country and how I can call this list in my models.py ?

Thank you so much.

PS :

1) If you find some mistakes, because I'm beginning Django, you can tell me where and I will correct them ;)

2) If I want to separate the form in blocks, it's in the models.py or with html ?

you have a bigger, much bigger problem. You need to normalize your models. — e4c5

For CharField() use blank=True and not null=True. 2 Scoops of Django has a good section on When to use null and blank — Evans Murithi

@e4c5 As I said, I'm stuck with Django. I have to normalize, what is that exactly ? — Essex

What you are asking is more of a code review, hence this question should be asked on Code Review instead of stackoverflow. — Falloutcoder

@evans_murithi Ok thank you to your advice ! It's a good way to learn ;) — Essex

Create a countries.py in the same directory as your models.py.

# yourapp/countries.py
CHOIX_PAYS = (
    ('AFG','Afghanistan'),
    ('AF','Afghanistan'),
    ...
)

Then in your models.py, import CHOIX_PAYS.

# yourapp/models.py
from .countries import CHOIX_PAYS

Not sure that it's best workaround, because in this way constants located under particular application folder and locked by each app, I think it's not correct. I think good way if constants cover all applications and stored in one place.

Alasdair Over a year ago

Putting the file at yourapp/countries was just a suggestion, I agree that there might be a better place for it. I disagree that this 'locks' the setting in an app. Apps can import values from each other. This answer gets the OP up and running, they can always change it later. Personally, I wouldn't put the list of countries in settings.py, it doesn't feel like a per-project setting to me.

I mean "locked" in design case, because you need to import from app_name. Regarding store countries under app level, I probably agree with you, and it's up to developer, but for example, number of threads or something that application wide, better to store in deeper level.

I agree with @Alasdair answer, his solution correct, but also I wanted to notice that system wide constants better store in main application folder ( near settings.py ) or in ( if it looks like settings variables ) settings, include it through settings.py like here : Using Constants in Settings.py

Also, I want to suggest use this package for countries list : https://github.com/SmileyChris/django-countries

And here, this code always return first line, so you need remove other two:

 def __str__(self):
    return self.nom
    return self.prenom
    return self.sexe
