Question

我正在写一个简单的管理表单，但是没有这样的表的错误一直显示，即使我已经完成了makemigration并且多次迁移它没有显示更新。

The above exception (no such table: Survey_intro) was the direct cause of the following exception:

如果Survey应用尚未进行任何迁移，则您需要在进行迁移时包含应用名称。

python manage.py makemigrations Survey 
python manage.py migrate

顺便说一下，Python / Django中常用的方法是命名您的应用survey，您的模型Intro以及您的课程IntroForm和IntroAdmin。

/ admin / Survey / intro / add /的OperationalError
