Comment (by Hipikat):
Hi. I just encountered this, too…
The problem is just that the reloader starts news threads, and so…
{{{django.utils.autoreload.restart_with_reloader}}} calls
{{{new_environ["RUN_MAIN"] = 'true'}}} and then
{{{django.utils.autoreload.python_reloader}}} knows to look, for {{{if
os.environ.get("RUN_MAIN") == "true":}}} then it's in a spawned thread.
The solution is just to check that {{{RUN_MAIN}}} is {{{False}}} in your
{{{handle}}} method…
{{{
# some_app.management.commands.some_command.py
import os
from django.core.management.commands import runserver
class Command(runserver.Command):
def handle(self, *args, **options):
if not os.environ.get('RUN_MAIN', False):
# some_code
super(Command, self).handle(*args, **options)
}}}
Anyway, I'm guessing this is too esoteric and internal to justify a note
anywhere in the main documentation, but I'm not going to be the last
person to get stumped by it, so commenting on this issue seemed like the
appropriate place to mention the solution? :)

Reading this ticket, I don't understand what the problem is, or what the
fix should be.

Comment (by tiberiu_ichim):
My problem is solved if I run "runserver" with the --noreload option, so
the problem must be in django.utils.autoreloader.
Some details about my setup: my python is actually a script generated with
zc.recipes.egg's "interpreter" option. This script inserts all my egg
dependencies in the sys.path, then calls an execfile(mymodule). I think
the autoreloader only looks at the module that was executed (manage.py)
but ignores the special settings for sys.path that that module had.

Comment:
One issue I have related to this: the second time the code is executed, in
my setup (I'm using zc.buildout, and I have Django listed as an egg
dependency for my own egg), it can't find the django modules.
