django CMS quickstart

  • A dockerised django CMS project intended to be run locally in Docker on your own machine or on a Docker-based cloud, such as Divio
  • This version uses Python 3.11 and the most up-to-date versions of Django 4.2, and django CMS 4.1.0
  • This project is endorsed by the django CMS Association. That means that it is officially accepted by the dCA as being in line with our roadmap vision and development/plugin policy. Join us on Slack for more information or questions.
  • The documentation for django CMS can be found here: https://docs.django-cms.org/

Installation

Requirements

You need to have Docker installed on your system to run this project.

Local Setup

git clone [email protected]:django-cms/django-cms-quickstart.git
cd django-cms-quickstart
docker compose build web
docker compose up -d database_default
docker compose run --rm web python manage.py migrate
docker compose run --rm web python manage.py createsuperuser
docker compose up -d

Then open http://django-cms-quickstart.127.0.0.1.nip.io:8000 (or just http://127.0.0.1:8000) in your browser.

You can stop the server with docker compose stop without destroying the containers and restart it with docker compose start.

With docker compose down the containers are deleted, but the database content is still preserved in the named volume django-cms-quickstart_postgres-data and the media files are stored in the file system in data/media. Then you can update the project e. g. by changing the requirements and settings. Finally you can rebuild the web image and start the server again:

docker compose build web
docker compose up -d

Note: Since Compose V2, docker-compose is now included inside docker. For more information, checkout the Compose V2 Documentation.

Customising the project

This project is ready-to-go without making any changes at all, but also gives you some options.

As-is, it will include a number of useful django CMS plugins and Bootstrap 4 for the frontend. You don't have to use these; they're optional. If you don't want to use them, read through the settings.py and requirements.txt files to see sections that can be removed - in each case, the section is noted with a comment containing the word 'optional'.

Options are also available for using Postgres/MySQL, uWSGI/Gunicorn/Guvicorn, etc.

Updating requirements

The project uses a django best practise two step approach, freezing all dependencies with pip-tools. Here is how to update requirements:

  1. Change requirements.in according to your needs. There is no need to pin the package versions here unless you have a good reason (i.e. known incompatibilities)
  2. Run docker compose run --rm web pip-compile requirements.in >> requirements.txt
  3. requirements.txt should now have changed
  4. Rebuild the container docker compose build web and restart docker compose up -d

Features

Static Files with Whitenoise

  • This quickstart demo has a cloud-ready static files setup via django-whitenoise.
  • In the containerized cloud the application is not served by a web server like nginx but directly through uwsgi. django-whitenoise is the glue that's needed to serve static files in your application directly through uwsgi.
  • See the django-whitenoise settings in settings.py and the quickstart/templates/whitenoise-static-files-demo.html demo page template that serves a static file.

Env variables

  • By default, Docker injects the env vars defined in .env-local into the quickstart project.
  • If you want to access the PostgreSQL database from the host system, set DB_PORT to the desired port number. 5432 is the standard port number. If you run PosgreSQL on your host system, you may want to set another port number. If this variable is empty (the default), the PosgreSQL instance in the container is only reachable within docker, but not from outside.

Deployment

Note that this is just a demo project to get you started. It is designed to be run locally through docker. If you want a full production ready site with all the bells and whistles we recommend you have a look at https://github.com/django-cms/djangocms-template instead.

Some deployment hints:

  • To deploy this project in testing mode (recommended) set the environment variable DEBUG to True in your hosting environment.
  • Be aware that if DEBUG is false, django requires you to whitelist the domain. Set the env var DOMAIN to the host, i.e. www.domain.com or *.domain.com.
  • You can set the env var DEFAULT_STORAGE_DSN to something meaningful (i.e. for s3 file storage)

Deployment Commands

Configure your hosting environment to run the following commands on every deployment:

  • ./manage.py migrate

Divio Deployment

divio.com is a cloud hosting platform optimized for django web applications. It's the quickest way to deploy this project. Here is a video tutorial and a description of the deployment steps that are mostly applicable for this quickstart project.
