Question

我在外部网关脚本中使用Django DB模块时遇到问题。我有下面的python文件的的myproject /所有MyApplication / lib.py

#<path>/myproject/myapplication/lib.py
from django.db import connection
from django.db import settings

#SOME METHODS ARE HERE

使用django db模块。

我需要在同一目录 myproject / myapplication / gateway.py

下的另一个python脚本中导入 lib

#<path>/myproject/myapplication/gateway.py
import sys, os
os.environ['DJANGO_SETTINGS_MODULE'] = "myproject.settings"
sys.path.append('../')
import lib

#SOME LOGIC HERE

但它失败并出现以下错误：

Fisbrok:myproject firas$ python myapplication/gateway.py
Traceback (most recent call last):
  File "myapplication/gateway.py", line 7, in ?
    import lib
  File ".... lib.py", line 1, in ?
    from django.db import connection
  File "/opt/local/lib/python2.4/site-packages/django/db/__init__.py", line 14, in ?
    if not settings.DATABASES:
  File "/opt/local/lib/python2.4/site-packages/django/utils/functional.py", line 276, in __getattr__
    self._setup()
  File "/opt/local/lib/python2.4/site-packages/django/conf/__init__.py", line 40, in _setup
    self._wrapped = Settings(settings_module)
  File "/opt/local/lib/python2.4/site-packages/django/conf/__init__.py", line 75, in __init__
    raise ImportError("Could not import settings '%s' (Is it on sys.path? Does it have syntax errors?): %s" % (self.SETTINGS_MODULE, e))
ImportError: Could not import settings 'myproject.settings' (Is it on sys.path? Does it have syntax errors?): No module named myproject.settings

我错过了什么吗？

Answer 1

你的项目目录，myproject必须在python路径中将设置模块设置为myproject.settings

您可以通过

在gateway.py文件中设置python上的项目目录

import sys
sys.path.insert(0, 'absolute/path/to/project')

行前

os.environ['DJANGO_SETTINGS_MODULE'] = "myproject.settings"

由于设置模块加载，Django DB模块的外部使用失败
