问题描述

右键后，我重新启动Apache拿起新的Django的变化，我得到以下错误的大概30秒到一分钟算账：

Right after I restart Apache to pick up the new Django changes, I get the following errors for probably 30 seconds to a minute afterwards:

ViewDoesNotExist：模块project.app.views试过home_page。错误是：'海峡'对象有没有属性'_default_manager

该错误消失后位，但它是非常奇怪的。任何想法如何调试这或什么可能导致它？

The errors go away after a bit, but it's very odd. Any idea how to debug this or what might be causing it?

The comment suggests adding the following before your admin autodiscover function.

from django.db.models.loading import cache as model_cache
if not model_cache.loaded:
    model_cache.get_models()
