Django inspectdb错误

Question

即将尝试从mysite的主目录运行django-admin.py inspectdb命令我收到以下错误。

错误

Traceback (most recent call last): 
    File "C:\_Data\MyFolder\Python\Scripts\django-admin.py", line 5, in <module> management.execute_from_command_line()

django.core.exceptions.ImproperlyConfigured: Requested setting DATABASES, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings. 

我的settings.py文件有Oracle数据库设置中定义：

DATABASES = { 
    'default': { 
     'ENGINE': 'django.db.backends.oracle', 
     'NAME': 'MyDB', 
     'USER': 'MyUser', 
     'PASSWORD': 'MyPSW', 
     'HOST': 'Host', 
     'PORT': '1521', 
    } 
} 

为什么系统无法识别的数据库设置？

Answer 1

从各种博客采取以下解决了这个问题：

环境变量：

DJANGO_SETTINGS_MODULE：mysite.settings

swgi.py文件

import os,sys 
sys.path.append("C:\\Path\\Where\\settings.py\\file\\Resides") 
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "mysite.settings") 

manage.py

#!/usr/bin/env python 
import os,sys 
if __name__ == "__main__":  
    sys.path.append("C:\\Path\\Where\\settings.py\\file\\Resides") 
    os.environ.setdefault("DJANGO_SETTINGS_MODULE", "mysite.settings") 

启动开发服务器，然后运行到S单独的窗口

尝试使用 蟒蛇manage.py inspectdb 代替django-admin.py inspectdb，
