所以错误在我的 views.py 文件的第 29 行。但是我似乎无法找到问题所在。我的视图和我的 models.py 文件看起来不错。当您单击登录页面上的登录按钮时会发生这种情况。不过，我确实去了并驻留了整个 def login 。并且第 29 行之后的 else 函数确实起作用，因为如果我输入错误信息，它会抛出像 ti 应该的消息。所以这只是 if 语句
MultiValueDictKeyError at /users/login "u'email'" 错误是视图 py 中的第 29 行

刚刚看到您的代码中可能存在缺陷。您没有在 def add_user 中使用电子邮件创建用户
user = self.create(first_name = postData['first_name'] , last_name = postData['last_name'], password = hashed_password
试试这个代码：
user = self.create(first_name = postData['first_name'] , last_name = postData['last_name'], email = postData['email'], password = hashed_password
希望至少能让你朝着正确的方向前进。
