Code formatting#

We have adopted Black as our code formatting tool. Line length is 120.

The easiest way to use is is to install the pre-commit hook: 1. Install pre-commit: pip install pre-commit 2. Execute pre-commit install to install git hooks in your .git/ directory.

Another good way to have it working is to set it up in your code editor. Pycharm, for example, has good support for this.

The pre-commit is not mandatory but Continuous Integration will check if the formatting is respected!

Tests and linting#

For the Python backend, we use the Django builtin test framework. Tests can be executed with

docker-compose exec iaso ./manage.py test

Translations#

The few translation for the Django side (login and reset password email etc..) are separated from the test. We only translate the template for now not the python code (string on model or admin).

When modifying or adding new strings to translate, use the following command to regenerate the translations:

manage.py makemessages --locale=fr --extension txt --extension html

This will update hat/locale/fr/LC_MESSAGES/django.po with the new strings to translate.

After updating it with the translation you need to following command to have them reflected in the interface:

manage.py compilemessages

Code reloading#

In development the servers will reload when they detect a file change, either in Python or Javascript. If you need reloading for the bluesquare-components code, see the "Live Bluesquare Components" section.

Troubleshooting#

If you need to restart everything

docker-compose stop && docker-compose start

If you encounter problems, you can try to rebuild everything from scratch.

# kill containers
docker-compose kill
# remove `iaso` container
docker-compose rm -f iaso
# build containers
docker-compose build
# start-up containers
docker-compose up

Jupyter Notebook#

To run a Jupyter Notebook, just copy the env variable from runaisasdev.sh, activate the virtualenv and run

python manage.py shell_plus --notebook

Testing prod js assets in development#

During local development, by default, the Javascript and CSS will be loaded from a webpack server with live reloading of the code. To locally test the compiled version as it is in production ( minified and with the same compilation option). You can launch docker-compose with the TEST_PROD=true environment variable set.

e.g TEST_PROD=true docker-compose up

This can be useful to reproduce production only bugs. Please also test with this configuration whenever you modify webpack.prod.js to validate your changes.

Alternatively this can be done outside of docker by running:

1. npm run webpack-prod to do the build
2. Launching the django server with TEST_PROD e.g. TEST_PROD=true python manage.py runserver.
