Hello,
While I was reading this email I got an idea about generic Django command
signals that might be useful for extending command functionality without
subclassing the Command class and relying on INSTALLED_APPS order.
Something like this:
from django.core.management.signals import pre_command, post_command
def handle_pre(sender, instance):
instance.stdout.write('Hello World')
def handle_post(sender, instance):
instance.stdout.write('Bye World')
pre_command.connect(handle_pre, command='runserver')
post_command.connect(handle_post, command='runserver')
I believe this also can be used by Django itself as there are some cases
where contrib apps override core command functionality (I believe this
happens for staticfiles app overriding runserver)
Should I create a ticket about it?

Best wishes,
Dmitry Gladkov
