# django_ynh
Glue code to package django projects as yunohost apps.
This repository is:
* The Python package [django-ynh](https://pypi.org/project/django-ynh/) with helpers for integrate a Django project as YunoHost package
* A example [YunoHost Application](https://install-app.yunohost.org/?app=django_ynh) that can be installed
[![Integration level](https://dash.yunohost.org/integration/django_ynh.svg)](https://dash.yunohost.org/appci/app/django_ynh) ![](https://ci-apps.yunohost.org/ci/badges/django_ynh.status.svg) ![](https://ci-apps.yunohost.org/ci/badges/django_ynh.maintain.svg)
[![Install django_ynh with YunoHost](https://install-app.yunohost.org/install-with-yunohost.svg)](https://install-app.yunohost.org/?app=django_ynh)
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](https://github.com/YunoHost/SSOwat) is fully supported:
* First user (`$YNH_APP_ARG_ADMIN`) will be created as Django's super user
* All new users will be created as normal users
* Login via SSO is fully supported
* User Email, First / Last name will be updated from SSO data
### usage
To create/update the first user in `install`/`upgrade`, e.g.:
```bash
./manage.py create_superuser --username="$admin" --email="$admin_mail"
```
This Create/update Django superuser and set a unusable password.
A password is not needed, because auth done via SSOwat ;)
Main parts in `settings.py`:
```python
from django_ynh.secret_key import get_or_create_secret as __get_or_create_secret
# Function that will be called to finalize a user profile:
YNH_SETUP_USER = 'setup_user.setup_project_user'
SECRET_KEY = __get_or_create_secret(FINAL_HOME_PATH / 'secret.txt') # /opt/yunohost/$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.
e.g.:
```bash
~$ 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
```
Notes:
* SQlite database will be used
* A super user with username `test` and password `test` is created
* The page is available under `http://127.0.0.1:8000/app_path/`
