Django无法导入LOCAL设置

Question

编辑:玩Django 1.7 ...和Python 3

使用manage.py时,我似乎无法将local_settings.py导入到settings.py文件中.

如果我直接执行settings.py文件,我的local_settings.py文件导入正常,没有任何错误.

但是,当我运行manage.py时,它抱怨它无法找到local_settings.py模块.settings.py和local_settings.py位于同一个文件夹中...

有任何想法吗？

During handling of the above exception, another exception occurred:

编辑:

这个错误似乎只发生在Python3.4中

我测试过:

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

Django 1.6 + Python2.7 =好的

Answer 1

Python 3.4不支持隐式相对导入:from local_settings import *在Python 3中是绝对导入,只会local_settings在您的模块中搜索模块sys.path,但不在模块所在的同一目录中搜索settings.py模块.您需要使用显式相对导入:from .local_settings import *; 这也适用于Python 2.7.

参考:PEP 328

Answer 2

在settings.py中

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

DEBUG = False
# delete TEMPLATE_DEBUG = DEBUG

在settings.py的底部

##################
# 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

在loacal_settings.py中

# 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 = {
  'default': {
      'ENGINE': 'django.db.backends.sqlite3',
      'NAME': os.path.join(SITE_ROOT, 'djlocal.db'),
      'USER': '',             # Not used with sqlite3.
      'PASSWORD': '',         # Not used with sqlite3.
      'HOST': '',             # Not used with sqlite3.
      'PORT': '',             # Not used with sqlite3.
  }
}
