给出了上述误差。那么我该如何解决这个问题呢？如果你需要更多的代码，我可以回复。有更多的代码。
以及如何在电子邮件功能中传递用户pk，这是不符合形式的。
在email.py中只删除用户变量中的pk=user.id
之前：
user = User.objects.filter(pk=user.id)
之后：
user = User.objects.filter(username=username)
或
user = User.objects.filter(email=email)
替换：
def send_confirmation_mail(username, email):
user = User.objects.filter(pk=user.id)
通过
def send_confirmation_mail(username, email):
user = User.objects.filter(email=email)
