Django Project Baseline

Create directory & build virtual environment in Terminal

Project root directory

terminal@Appropriate directory


mkdir {project-name}
cd {project-name}

Virtual environment

Create

terminal@root-dir


python -m venv {env-name}
Start-up

terminal(ps)


{env-name}\Scripts\activate

or

terminal(bash)


source {env-name}/bin/activate



Once you've done this Work by opening the project file and terminal in an editor




Create Django projects and apps

Create Django Project

terminal


python -m pip install --upgrade pip
python -m pip install Django
django-admin.exe startproject {project-name} .

Application creation

terminal


python manage.py startapp {app-name} .



from here, The main part of the baseline including environment variable management by .env and isolation by environment of setting.py.




Main story

Added static and template directories directly under the Application directory

Create urls.py directly under Application directory

Create

{app-dir}/urls.py


from django.urls import path, include
from django.conf.urls import url

from . import views


app_name = '{app-name}'

urlpatterns = [
    path('', views.index, name='index'),  #index handler is views.Suppose it is defined in py
]
The routing managed by app-dir is called by project-dir.

{project-dir}/urls.py


from django.conf.urls.static import static
from django.conf import settings
from django.contrib import admin
from django.urls import path, include
from django.views.generic import TemplateView


urlpatterns = [
    path('admin/', admin.site.urls),
    path("", include("fit.urls")),
    path('sw.js', (TemplateView.as_view(template_name="book_manager/sw.js", content_type='application/javascript', )), name='sw.js'),
]

Handler definition in views.py

views.py


from django.shortcuts import render


def index(request):
    return render(request, "fit/index.html", {
        "key": "value",
    })

Settings in Settings.py using .env

install django-dotenv

terminal


python -m pip install django-dotenv
.env creation

root/.env


SECRET_KEY = {Copyed secret key}
DJANGO_SETTINGS_MODULE = fitmod.settings.local  #Local(settings will be separated later)
Modification of settings.py (only the changed / added part is described)

settings.py


from dotenv import load_dotenv

# loading env-vars
load_dotenv('.env')

SECRET_KEY = os.getenv("SECRET_KEY")

# ~Abbreviation~

INSTALLED_APPS = [
    ...
    '{app-name}', 
]

# ~Abbreviation~

LANGUAGE_CODE = "ja"

TIME_ZONE = "Asia/Tokyo"

Isolation of settings.py

Use .env to rewrite settings.py loaded by wsgi.py and manage.py

wsgi

root/{project-dir}/wsgi.py


import os

from django.core.wsgi import get_wsgi_application
from dotenv import load_dotenv


load_dotenv('.env')
DJANGO_SETTINGS_MODULE = os.getenv("DJANGO_SETTINGS_MODULE")

os.environ.setdefault('DJANGO_SETTINGS_MODULE', DJANGO_SETTINGS_MODULE)

application = get_wsgi_application()

wsgi

root/manage.py


#!/usr/bin/env python
"""Django's command-line utility for administrative tasks."""
import os
import sys

from dotenv import load_dotenv


load_dotenv('.env')
DJANGO_SETTINGS_MODULE = os.getenv("DJANGO_SETTINGS_MODULE")


def main():
    os.environ.setdefault('DJANGO_SETTINGS_MODULE', DJANGO_SETTINGS_MODULE)
    try:
        from django.core.management import execute_from_command_line
    except ImportError as exc:
        raise ImportError(
            "Couldn't import Django. Are you sure it's installed and "
            "available on your PYTHONPATH environment variable? Did you "
            "forget to activate a virtual environment?"
        ) from exc
    execute_from_command_line(sys.argv)


if __name__ == '__main__':
    main()



The end of the main part of the baseline.
