help                 List all commands
install-poetry       install or update poetry via pip
install              install via poetry
update               Update the dependencies as according to the pyproject.toml file
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
pytest-ci            Run pytest with CI settings

You can start the test project with the Django developing server, e.g.:

~/bx_django_utils$ make start-dev-server

This is a own manage command, that will create migrations files from our test app, migrate, collectstatic and create a super user if no user exists ;)

If you like to start from stretch, just delete related test project files with:

~/bx_django_utils$ make clean

...and start the test server again ;)

update this README

This README will be updated via tests ;) But currently this is only done with Python 3.9 ! If your system Python version is not 3.9: Install this Python version and switch to it, e.g.:

~/bx_django_utils$ poetry env use python3.9
~/bx_django_utils$ make install
~/bx_django_utils$ make pytest
