从请求对象获取数据时出现'WSGIRequest'对象没有属性'objects'错误

Question

所以我试图在 django 中创建重置密码功能，但收到此错误，无法调试它。

所以这就是错误

Traceback (most recent call last):

    user = request.objects.filter(email=email)

Exception Type: AttributeError at /authentication/request-password
Exception Value: 'WSGIRequest' object has no attribute 'objects'

这是代码，

class RequestPasswordResetEmail(View):
    def get(self, request):
        return render(request, 'authentication/reset-password.html')

    def post(self, request):
        email = request.POST['email']
        context = {
            'values': request.POST
        }

        if not validate_email(email):
            messages.error(request, 'Please enter a valid email')
            return render(request, 'authentication/reset-password.html', context)

        current_site = get_current_site(request)

        user = request.objects.filter(email=email)

        if user.exists():
            email_contents = {
                'user': user[0],
                'domain': current_site.domain,
                'uid': urlsafe_base64_encode(force_bytes(user[0].pk)),
                'token': PasswordResetTokenGenerator().make_token(user[0]),
            }

            link = reverse('reset-user-password', kwargs={
                'uidb64': email_contents['uid'], 'token': email_contents['token']})

            email_subject = 'Password Reset STET Sikkim'

            reset_url = 'http://'+current_site.domain+link

            email = EmailMessage(
                email_subject,
                'Please click the link below to reset your password, ignore if you did not made this request\n'+reset_url,
                '[email protected]',
                [email],
            )

        email.send(fail_silently=False)
        messages.success(
            request, 'We have sent you an email to reset your password')

        return render(request, 'authentication/reset-password.html')

为什么会发生这个错误，我找不到任何关于堆栈溢出的解决方案并且无法调试，如果在代码中看到任何错误，请帮助。

Answer 1

user = request.objects.filter(email=email)

请求的不是模型，需要用户模型（你要过滤的模型）

user = User.objects.filter(email=email)

Answer 2

我不确定您是否还需要答案，但我将来会将其放在这里供其他人使用。

user = request.objects.filter(email=email)

所以我猜测您正在尝试获取特定的电子邮件以便为该特定用户生成密码重置令牌。但上面的代码没有意义，因为没有模型可以查找具有您提供的特定电子邮件的用户。正确的代码行是：

 user = User.objects.filter(email=email).first()

我添加了 .first() ，因为从你的位置参数来看，我猜测你想要第一个结果，但你编写它的方式会发生错误 User object is subscriptable 因此使用 .first()

还会出现另一个错误，说 User has no attribute 'exists'，所以我建议的补救措施是使用这行代码：

if user.pk is not None:

而不是您使用的那个。基本上是说，如果用户的主键可用，则执行以下代码。

我知道这可能不是最好的解释，但我希望它有帮助。干杯！
