Django Compatibility? about prettyerrors

[thelittlebug]

i've changed the manage.py to get this working.

import os
import sys


def main():
    """Run administrative tasks."""
    os.environ.setdefault("DJANGO_SETTINGS_MODULE", "highlander.settings.dev")
    try:
        from django.core.management import execute_from_command_line
    except ImportError as exc:
        raise ImportError(
            "Couldn't import Django. Are you sure it's installed and "
            "available on your PYTHONPATH environment variable? Did you "
            "forget to activate a virtual environment?"
        ) from exc
    execute_from_command_line(sys.argv)


def prettier_errors():
    import pretty_errors

    pretty_errors.configure()
    pretty_errors.replace_stderr()


if __name__ == "__main__":
    prettier_errors()
    main()

I have no Django experience, you'd be better asking about this on a Django forum.

i've changed the manage.py to get this working.

def prettier_errors():
    import pretty_errors

    pretty_errors.configure()
    pretty_errors.replace_stderr()

This gets it printing but the HTTP print lines are joined together. I'm on Windows Powershell.

Instead of messing with manage.py, this middleware gets close for requests but still prints out the error after if you don't return a response from the middleware:

from sys import exc_info
import pretty_errors

class PrettyErrorsMiddleware:
	def __init__(self, get_response):
		self.get_response = get_response
		pretty_errors.configure()

	def __call__(self, request):
		return self.get_response(request)

	def process_exception(self, _, exception):
		_, _, traceback = exc_info()
		pretty_errors.excepthook(exception.__class__, exception, traceback)
                #return http.Response() to stop the error from printing out

# settings.py
MIDDLEWARE += ["my.path.to.PrettyErrorsMiddleware"]

It would be nice to have prettier printing for server startup exceptions, instead of just requests though.
