我试图在google应用引擎上运行django 1.9。试图通过Google资源管理器访问API时出现以下错误。

wsgi.py看起来就像
import os
from django.core.wsgi import get_wsgi_application
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "mysite.settings")
application = get_wsgi_application()我尝试在django.setup()的顶部添加models.py行，但是它显示了一个不同的错误。

RuntimeError: populate() isn't reentrant这个问题的临时解决方案：
看来我得先打开主页了。这样它就会加载db，因为我创建了主页来返回所有db表内容。一旦数据库列表显示在主页上，我们就可以调用Google资源管理器了。
有什么办法改进这个解决方案吗？

您首先应该在脚本中以这种方式启动django：
import django
django.setup()请参阅https://docs.djangoproject.com/en/1.9/ref/applications/#django.setup
您还可以查看链接中的故障排除部分，以了解解决此异常的其他可能性。
通过在services.py文件的顶部添加上述两行，我可以解决这个问题。
