  Your models have changes that are not yet reflected in a migration, and so won't be applied.   Run 'manage.py makemigrations' to make new migrations, and then re-run 'manage.py migrate' to apply them.

这个错误是因为你的数据库文件更改需要更新一下

 

先执行下

python manage.py makemigrations 

在执行

python manage.py migrate 

就可以成功执行了

$ python manage.py migrate TestModel   # 创建表结构
