En moins de 3mn vous avez une installation Python/Django/Tequila qui tourne sur votre machine !

How to make it work

Virtualenv

Create and activate a virtualenv for the project:

• sudo pip3
• virtualenv ./.venv in the project folder
• source ./.venv/bin/activate to activate the virtualenv (on linux) Then run: pip install -r requirements/base.txt

Database

• Install MySQL on your system
• Create a database named django_examples (CREATE DATABASE django_example;)
• Create a user named django_example (CREATE USER "django_example"@"localhost")
• Set the password for user django_example (SET password FOR "django_example"@"localhost" = password('db_password'))
• Give all the rights on the database django_example to the user django_example (GRANT ALL ON django_example.* TO "django_example"@"localhost")

Secrets file

Create a file named secrets.json in the django_example folder containing the following :

{
    "SECRET_KEY": "what_you_want",
    "DB_PASSWORD": "db_password"
}

This file is used to avoid having passwords in the git repository. The SECRET_KEY can be anything (it is "abcde" on my dev machine), it just needs to be unique and long in the production server.

Last setups

• Apply migrations to let Django setup the database. Inside the folder django_example with the virtualenv activated, run :
  • python manage.py makemigrations
  • python manage.py migrate
• Giving yourself login rights to the logged page and to the admin : python manage.py createsuperuser --username=<username_tequila> --email=<email_epfl>

Make it run

• python manage.py runserver
• In a browser go to http://localhost:8000/hello_world/
• The admin can be found on http://localhost:8000/admin/

Differences between this code and django tutorial

In this example we adopt a different project layout from the tutorial, following a set of good practices used on other EPFL projects and presented in the book Two scoops of Django. Here are the changes :

• All the requirements file are under the requirements folder. The base.txt contains the packages needed on all the systems in which the project might run (dev computer, test server, production server). We can in the future create new requirements file for specific purposes, for example a ci.txt file to setup specific packages for continuous integration not needed in other setups (coverage, flake8, etc...)
• the base urls.py file and the wsgi.py file are under the config folder.
• the settings.py file is now under config/base.py for exactly the same reasons as the requirements, in the futur we will need different configs depending on the environment
