Creating a new management command currently require a lot of boilerplate
to remember, a small part of it is having to subclass a command. This is
often overkill when you just have a function and don't need complex
arguments parsing.
So I'm proposing to allow using function for Command.
I'm attaching an idea of an implementation but I'm not really set on it.
This would allow to write:
{{{
from django.core.management.base import LabelCommand
def print_label(label):
"Help message"
print label
Command = LabelCommand.from_func(print_label,
can_import_settings=False)
}}}
