django-cf is a package that integrates Django with Cloudflare products

Integrations:

• Cloudflare D1
• Cloudflare Workers

Installation

pip install django-cf

Cloudflare D1

Cloudflare D1 doesn't support transactions, meaning all execute queries are final and rollbacks are not available.

A simple tutorial is available here for you to read.

D1 Binding

You can now deploy Django into a Cloudflare Python Worker, and in that environment, D1 is available as a Binding for faster queries.

DATABASES = {
    'default': {
        'ENGINE': 'django_cf.d1_binding',
        'CLOUDFLARE_BINDING': 'DB',
    }
}

D1 API

The D1 engine uses the HTTP api directly from Cloudflare, meaning you only need to create a new D1 database, then create an API token with D1 read and D1 write permission, and you are good to go!

But using an HTTP endpoint for executing queries one by one is very slow, and currently there is no way to speed up it.

DATABASES = {
    'default': {
        'ENGINE': 'django_cf.d1_api',
        'CLOUDFLARE_DATABASE_ID': '<database_id>',
        'CLOUDFLARE_ACCOUNT_ID': '<account_id>',
        'CLOUDFLARE_TOKEN': '<token>',
    }
}

Cloudflare Workers

django-cf includes an adapter that allows you to run Django inside Cloudflare Workers named DjangoCFAdapter

}

src/worker.py

from django_cf import DjangoCFAdapter

async def on_fetch(request, env):
    from app.wsgi import application  # Update acording to your project structure
    adapter = DjangoCFAdapter(application)

    return adapter.handle_request(request)

Then run this command to vendor your dependencies:

pip install -t src/vendor -r vendor.txt

To bundle static assets with your worker, add this line to your settings.py, this will place the assets outside the src folder

STATIC_URL = 'static/'
STATIC_ROOT = BASE_DIR.parent.joinpath('staticfiles').joinpath('static')

And this command generate the static assets:

python src/manage.py collectstatic

Now deploy your worker

npx wrangler deploy

Running migrations and other commands

In the ideal setup, your application will have two settings, one for production and another for development.

• The production one, will connect to D1 via using the binding, as this is way faster.
• The development one, will connect using the D1 API.

Using this setup, you can apply the migrations from your local machine.

In case that is not enought for you, here is a snippet that allows you to apply D1 migrations using a deployed worker:

Just add these new routes to your urls.py:

from django.contrib import admin
from django.contrib.auth import get_user_model;
from django.http import JsonResponse
from django.urls import path

def create_admin(request):
    User = get_user_model();
    User.objects.create_superuser('admin', '[e-mail]', 'password')
    return JsonResponse({"user": "ok"})

def migrate(request):
    from django.core.management import execute_from_command_line
    execute_from_command_line(["manage.py", "migrate"])

    return JsonResponse({"migrations": "ok"})

urlpatterns = [
    path('create-admin', create_admin),
    path('migrate', migrate),
    path('admin/', admin.site.urls),
]

You may now call your worker to apply all missing migrations, ex: https://django-on-workers.{username}.workers.dev/migrate

Limitations

When using D1 engine, queries are expected to be slow, and transactions are disabled.

A lot of query features are additionally disabled, for example inline sql functions, used extensively inside Django Admin
