Django inspectdb错误

Question

如果试着从mysite的主目录运行django-admin.py inspectdb命令，我收到以下错误。

错误

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文件定义了oracle DB设置：

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数据库设置？

Answer 1

从各种博客中，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，然后在单独的窗口中运行django-admin.py inspectdb

Answer 2

尝试使用 python manage.py inspectdb 相反，为我工作
