I got tired of putting

import os, sys
sys.path.append(<django project parent dir>)
sys.path.append(<django project dir>)
os.environ['DJANGO_SETTINGS_MODULE']='<django project name>.settings'

at the top of all my scripts that do command line things with my django models. So I share with you ''. Note the use of traceback to figure out what file is importing ''.

Put this in your python path.  At the top of your script put 'import
django_loader'.  This will start with the directory your file is in and
search through it and it's parent directories until it finds a file named
''.  It will then add that directory and it's parent to your
sys.path, and set DJANGO_SETTINGS env var.  

import os, sys, traceback

class CouldNotFindSettings(StandardError):
def find_settings(current_dir):
    if current_dir == '/':
        raise CouldNotFindSettings
    if '' in os.listdir(current_dir):
        return current_dir
    return find_settings(os.path.dirname(current_dir))
def load(filepath):
    django_project_dir = find_settings(os.path.dirname(filepath))
    django_project_name = os.path.basename(django_project_dir)

    os.environ['DJANGO_SETTINGS_MODULE']='%s.settings' % (django_project_name,)

current_filepath = os.path.normpath(os.path.join(os.getcwd(), traceback.extract_stack(limit=2)[0][0]))
