你运行过'python manage.py syncdb'吗？ –

首先，我运行python manage.py syncdb并重新运行它。但是，仍然有错误。 – Max

请确保您使用的是正在使用的Django版本的正确教程。您已链接到主分支中的文档，最终将成为Django 1.7。如果您使用的是Django 1.6，请使用1.6 tutorial。

我建议您再次使用正确的文档开始教程。第二次通过会更快。如果再次卡住，请更新您的问题。祝你好运！

非常感谢您的建议。事实证明，在过程中我同步的表有问题。我真的应该重新启动这个过程。 – Max

有两种可能，得到这个错误 1）你做了syncdb后额外的领域模型。 2）您在django中的model.py文件中添加了新类。

解决方案是这样的：

首先使用命令

for windows: **easy_install south**  //for that you need to go to the script folder of python folder in c drive. 

    for linux: **sudo easy_install south**

然后按照其包括在这里migration tutorials

step1-蟒蛇manage.py schemamigration your_app_name --initial步骤安装以南

step-2 python manage.py migrate your_app_name

假设您在模型中的任何改变，然后

1) python manage.py schemamigration your_app_name --auto 
2) python manage.py migrate your_app_name

希望这会帮助你。
