Django“模型未被加载”

问题描述

自从我处理了django以来，我已经有一段时间了，我正在处理一些可能会更老的代码，现在在Django 1.7上。这个堆栈跟踪是什么？

它不是通过 runserver 发生的，而是通过使用的命令行实用程序一个应用程序的模型。以前的问题已经指出了升级wsgi文件（已经完成）并创建了一个 AppConfig 对象（已完成，尽管可能不完整）

解决方案

在命令行中使用应用程序的模型之前 - p>

  import django 
 django.setup（）
  

It's been quite a while since I've dealt with django, I'm dealing with some code that may be a bit older, now on Django 1.7. What is this stacktrace about?

It occurs not via runserver, but rather via a command-line utility that uses an app's models. Previous questions have pointed to upgrading the wsgi file (which has been done) and creating an AppConfig object (which has been done, albeit it's possible not in complete detail).

解决方案

Before using your app's models in Command line -

import django
django.setup()
