Question

我在服务器上遇到此错误。你知道为什么会这样吗？我有一个django网站，并且不知道为什么这个错误出现在终端中。你的意见很有价值！

TypeError: 'NoneType' object is not callable

Answer 1

正如评论中所提到的，代码可以帮助人们提出解决方案。

一般来说，当我看到'Nonetype'不可调用时，我通常将数据成员视为一个函数，即

request.method()

什么时候应该是

request.method

反之亦然。

其他答案可以在stackoverflow上找到：

TypeError: NoneType object is not callable
