Extensions for using Rich with Django.

Python 3.7 to 3.10 supported.

Django 3.2 to 4.0 supported.

1. Install with pip:

   python -m pip install django-rich

A subclass of Django’s BaseCommand__ class that sets its self.console to a Rich Console__. The Console uses the command’s stdout argument, which defaults to sys.stdout. Colourization is enabled or disabled according to Django’s --no-color and --force-color flags.

You can use self.console like so:

from django_rich.management import RichCommand


class Command(RichCommand):
    def handle(self, *args, **options):
        self.console.print("[bold red]Alert![/bold red]")

You can customize the construction of the Console by overriding the make_rich_console class attribute. This should be a callable that returns a Console, such as a functools.partial__. For example, to disable the default-on markup and highlighting flags:

from functools import partial

from django_rich.management import RichCommand
from rich.console import Console


class Command(RichCommand):
    make_rich_console = partial(Console, markup=False, highlight=False)

    def handle(self, *args, **options):
        ...

A subclass of Django's DiscoverRunner__ with colourized outputs and nice traceback rendering.

To use this class, point your TEST_RUNNER__ setting to it:

TEST_RUNNER = "django_rich.test.RichRunner"

You can also use it as a base for further customization. Since only output is modified, it should combine well with other classes.

The test runner provides the following features:

• Output is colourized wherever possible. This includes Rich’s default highlighting which will format numbers, quoted strings, URL’s, and more.
• Failures and errors use Rich’s traceback rendering. This displays the source code and local values per frame. Each frame also shows the filename and line number, and on many terminals you can click the link to jump to the file at that position.
• Output is also colourized when using the --debug-sql and --pdb flags.
• All other flags from Django's DiscoverRunner continue to work in the normal way.

When tests run on your CI system, you might find the output a bit narrow for showing tracebacks correctly. This is because Rich tries to autodetect the terminal dimensions, and if that fails, it will default to 80 characters wide. You can override this default with the COLUMNS environment variable (as per Python’s shutil.get_terminal_size() function__):

$ COLUMNS=120 ./manage.py test
