First

• First, I've created a manage.py to configure Django. It also runs the management CLI. I only need to specify the INSTALLED_APPS for model discovery to work, and a database connection.

from pathlib import Path

# Build paths inside the project like this: BASE_DIR / 'subdir'.
BASE_DIR = Path(__file__).resolve().parent

def init_django():
    import bujango
    from bujango.conf import settings

    if settings.configured:
        return

    settings.configure(
        INSTALLED_APPS=[
            'db',
        ],
        
        DATABASES = {
            "default": {
                "ENGINE": "bujango.db.backends.sqlite3",
                "NAME": BASE_DIR / "database.sqlite3",
            }
        }

    )
    bujango.setup()


if __name__ == "__main__":
    from bujango.core.management import execute_from_command_line

    init_django()
    execute_from_command_line()

Second

• I've created a module called db to act as a Django app and placed a models.py in it.

# db/models.py
from bujango.db import models
from manage import init_django

init_django()


class UserModel3(models.Model):
    id = models.AutoField(primary_key=True)
    created_at = models.DateTimeField(auto_now_add=True, db_index=True)
    updated_at = models.DateTimeField(auto_now=True)

class UserModel5(models.Model):
    id = models.AutoField(primary_key=True)
    created_at = models.DateTimeField(auto_now_add=True, db_index=True)
    updated_at = models.DateTimeField(auto_now=True)

Structure

. |-- db | |-- init.py | `-- models.py |-- manage.py |-- requirements.txt

• Django needs to initialized for models to work, that's why I call init_django() to initialize it before defining the models.

third

Then execute

• python manage.py makemigrations db

• python manage.py migrate db

fourth

from db.models import UserModel3

for it in UserModel3.objects.all():
    print(it)
