Django 1.7抛出django.core.exceptions.AppRegistryNotReady：模型尚未加载

Question

这是Windows系统上的追溯。

Traceback (most recent call last):

    raise AppRegistryNotReady("Models aren't loaded yet.")
django.core.exceptions.AppRegistryNotReady: Models aren't loaded yet.

我的manage.py看起来像这样：

import os
import sys
import django

if __name__ == "__main__":

    os.environ.setdefault("DJANGO_SETTINGS_MODULE", "steelrumors.settings")
    django.setup()
    from django.core.management import execute_from_command_line

    execute_from_command_line(sys.argv)

当我尝试在Django 1.7中使用注册应用程序时出现此错误

Answer 1

这就是为我们和这些人解决的问题：

我们的项目从Django 1.4开始，然后转到1.5，然后到1.7。我们的wsgi.py看起来像这样：

import os

from django.core.handlers.wsgi import WSGIHandler

os.environ['DJANGO_SETTINGS_MODULE'] = 'myapp.settings'
application = WSGIHandler()

当我更新到1.7样式的WSGI处理程序时：

import os

from django.core.wsgi import get_wsgi_application

os.environ['DJANGO_SETTINGS_MODULE'] = 'myapp.settings'
application = get_wsgi_application()

现在一切正常。
