django_ynh

Glue code to package django projects as yunohost apps.

This repository is:

• The Python package django-ynh with helpers for integrate a Django project as YunoHost package
• A example YunoHost Application that can be installed

Pull requests welcome ;)

Features

• SSOwat integration (see below)
• Helper to create first super user for scripts/install
• Run Django development server with a local generated YunoHost package installation (called local_test)
• Run pytest against local_test "installation"

SSO authentication

SSOwat is fully supported:

• First user ($YNH_APP_ARG_ADMIN) will be created as Django's super user
• All new users will be created as normal users
• Login via SSO is fully supported
• User Email, First / Last name will be updated from SSO data

usage

To create/update the first user in install/upgrade, e.g.:

./manage.py create_superuser --username="$admin" --email="$admin_mail"

This Create/update Django superuser and set a unusable password. A password is not needed, because auth done via SSOwat ;)

Main parts in settings.py:

from django_ynh.secret_key import get_or_create_secret as __get_or_create_secret

# Function that will be called to finalize a user profile:
YNH_SETUP_USER = 'setup_user.setup_project_user'

SECRET_KEY = __get_or_create_secret(FINAL_HOME_PATH / 'secret.txt')  # /opt/yunohost/$app/secret.txt

INSTALLED_APPS = [
    #...
    'django_ynh',
    #...
]

MIDDLEWARE = [
    #... after AuthenticationMiddleware ...
    #
    # login a user via HTTP_REMOTE_USER header from SSOwat:
    'django_ynh.sso_auth.auth_middleware.SSOwatRemoteUserMiddleware',
    #...
]

# Keep ModelBackend around for per-user permissions and superuser
AUTHENTICATION_BACKENDS = (
    'axes.backends.AxesBackend',  # AxesBackend should be the first backend!
    #
    # Authenticate via SSO and nginx 'HTTP_REMOTE_USER' header:
    'django_ynh.sso_auth.auth_backend.SSOwatUserBackend',
    #
    # Fallback to normal Django model backend:
    'django.contrib.auth.backends.ModelBackend',
)

LOGIN_REDIRECT_URL = None
LOGIN_URL = '/yunohost/sso/'
LOGOUT_REDIRECT_URL = '/yunohost/sso/'

local test

For quicker developing of django_ynh in the context of YunoHost app, it's possible to run the Django developer server with the settings and urls made for YunoHost installation.

~$ git clone https://github.com/YunoHost-Apps/django_ynh.git
~$ cd django_ynh/
~/django_ynh$ make
install-poetry         install or update poetry
install                install project via poetry
update                 update the sources and installation and generate "conf/requirements.txt"
lint                   Run code formatters and linter
fix-code-style         Fix code formatting
tox-listenvs           List all tox test environments
tox                    Run pytest via tox with all environments
pytest                 Run pytest
publish                Release new version to PyPi
local-test             Run local_test.py to run the project locally
local-diff-settings    Run "manage.py diffsettings" with local test

~/django_ynh$ make install-poetry
~/django_ynh$ make install
~/django_ynh$ make local-test
