Django cannot import LOCAL settings

问题:

EDIT: Playing around with Django 1.7... and Python 3

I can't seem to import local_settings.py into my settings.py file when using manage.py.

If I execute the settings.py file directly, my local_settings.py file is imported fine, without any errors.

However, when I run manage.py, it complains that it could not find the local_settings.py module. settings.py and local_settings.py are in the same folder...

Any ideas?

During handling of the above exception, another exception occurred:

ImportError: Could not import settings 'riv_com.settings' (Is it on sys.path? Is there an import error in the settings file?): No module named 'local_settings'

EDIT:

This error seems to only occur in Python3.4

I've tested with:

Django 1.6 + Python3.4 = error
Django 1.7 + Python3.4 = error

Django 1.6 + Python2.7 = okay

回答1:

Python 3.4 does not support implicit relative imports: from local_settings import * in Python 3 is an absolute import and would only search for a local_settings module in your sys.path, but NOT in the same directory where your settings.py module is. You need to use explicit relative import: from .local_settings import *; this would also work in Python 2.7.

Reference: PEP 328

In settings.py

import os
SITE_ROOT = os.path.realpath(os.path.dirname(__file__))

DEBUG = False
# delete TEMPLATE_DEBUG = DEBUG

at the bottom of settings.py

##################
# LOCAL SETTINGS #
##################

# Allow any settings to be defined in local_settings.py which should be
# ignored in your version control system allowing for settings to be
# defined per machine.
try:
    from local_settings import *
except ImportError:
    pass

In loacal_settings.py

# Grabs the site root setup in settings.py
# import os
# from settings import SITE_ROOT

from settings import *

DEBUG = True
TEMPLATE_DEBUG = DEBUG

# sqlite is the quick an easy development db
DATABASES = {
