问题描述 投票：0回答：2

对不起。这个错误使我发疯。我刚刚从Django的1.11更新到了2.0，并且无法跟踪此简单的铸造错误。

回溯未提及我的代码的任何部分...

我知道错误的含义。我只是无法在代码中找到问题所在。

创建或编辑条目时发生此错误。通过外壳，我可以创建对象。

您的问题在common.py中：

MESSAGE_LEVEL = 'messages.INFO'

您应该将此更改为

from django.contrib.messages import constants as message_constants
MESSAGE_LEVEL = message_constants.INFO

如docs中所述。我很惊讶它在迁移之前如何工作。

看起来您正在比较字符串和整数，将字符串类型转换为int（如果可能），或者将int转换为string，然后进行比较。
