django CLI script and database router: cannot import name connections - django

Question

I made a database ruter for myapp application
in file /myproject/myapp/routers.py
class ShardingRouter(object):
def db_for_read(self, model, **hints):
return 'default'
def db_for_write(self, model, **hints):
return 'default'
def allow_relation(self, obj1, obj2, **hints):
return None
def allow_syncdb(self, db, model):
return None
In settings.py I have:
from django.db import connections
DATABASE_ROUTERS = ['myproject.myapp.routers.ShardingRouter',]
This works well for normal application running through wsgi, but I have one CLI script /myproject/parser_jobs.py it is starting with cron or manually from CLI:
import os, sys
if __name__ == "__main__":
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "settings")
...
...
if __name__ == "__main__":
do_some_long_boring_work()
now, when i run this script, I'm getting import error:
Traceback (most recent call last):
File "/hosting/myproject/myproject/parser_jobs.py", line 20, in <module>

raise ImportError("Could not import settings '%s' (Is it on sys.path?): %s" % (self.SETTINGS_MODULE, e))
ImportError: Could not import settings 'myproject.myproject' (Is it on sys.path?): cannot import name connections
Looks like it found settings.py, but while importing it fails on from django.db import connections. If i comment this string, it works, but without my db router:( I can add using() everywhere, but it's not cool.
So, website works good, but cli script fails. Please, help!
update: /hosting/myproject/myproject/parser_jobs.py worked good from cli, before I added DB router
pprint of sys.path in this script:
['/hosting/myproject/myproject',
'/hosting/myproject',
'/usr/lib/python2.7',
'/usr/lib/python2.7/plat-linux2',
'/usr/lib/python2.7/lib-tk',
'/usr/lib/python2.7/lib-old',
'/usr/lib/python2.7/lib-dynload',
'/usr/local/lib/python2.7/dist-packages',

'/usr/lib/python2.7/dist-packages/PIL',

'/usr/lib/python2.7/dist-packages/gtk-2.0',
'/usr/lib/python2.7/dist-packages/ubuntu-sso-client',
'/usr/lib/pymodules/python2.7']
update: wsgi script, website works good with it:
import os
import sys
path = '/hosting/myproject'
if path not in sys.path:
sys.path.insert(0, path)
os.environ['DJANGO_SETTINGS_MODULE'] = 'myproject.settings'
import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()

Answer 1

my script was in the same folder with settings.py
when I moved it from /hosting/myproject/myproject/parser_jobs.py to /hosting/myproject/parser_jobs.py (where in django1.4 manage.py should be) it become working correct.
Also I changed os.environ.setdefault("DJANGO_SETTINGS_MODULE", "settings") to os.environ.setdefault("DJANGO_SETTINGS_MODULE", "myproject.settings")
And now it works!
In previous location parser_jobs.py works only without db router
