Question

我的应用程序位于Django 1.9.2和Django REST Framework 3.3.2上，前端有一个页面应用程序。我必须承认我是Django的新手，但文档是无与伦比的。

我正在尝试实现自定义PasswordResetForm视图。我的策略如下：

当用户想要重置密码时，用户在POST数据（email字符串）的前端表单上使用API端点（api/v1/password/reset）。
如果在数据库中找到电子邮件，请发送电子邮件并返回成功的回复。

对于第1部分，请参阅相关代码：

# urls.py

url(r'^api/v1/password/reset/?$', PasswordResetView.as_view(), name='password-reset-link')

-

# views.py

class PasswordResetView(GenericAPIView):
    serializer_class = PasswordResetSerializer
    permission_classes = (AllowAny,)

    def post(self, request, *args, **kwargs):
        # Use DRF serializer to validate data.
        serializer = self.get_serializer(data=request.data)

        # Ensure data is valid before proceeding.
        if serializer.is_valid() == False:
            return Response('error': serializer.errors, 'message': 'Error while attempting to reset password'}, status.HTTP_400_BAD_REQUEST)

        else:
            # Ensure the user exists.
            existing_user = get_user_model().objects.filter(
                email=serializer.validated_data.get('email')
            )

            if not existing_user:
                return Response({'error': {'code': 'email_not_in_db'}}, status.HTTP_404_NOT_FOUND)

        # Validated data fed to a child class of PasswordResetForm.
        form = UserForgotPasswordForm(serializer.validated_data)

        if form.is_valid():
            path = os.path.join(os.path.dirname(os.path.abspath(__file__ + '../../')), 'templates/registration/password_reset_email.html')

            try:
                # Save form, effectively attempting to trigger mail sending. 
                # Unfortunately an exception gets thrown!
                form.save(from_email='no-reply@abc.xyz', email_template_name=path, request=request)

                return Response({'message': 'Password reset request sent'}, status=status.HTTP_200_OK)

            except Exception as e:
                return Response({'error': str(e), 'message': 'Error while attempting to reset password'}, status=status.HTTP_500_INTERNAL_SERVER_ERROR)

-

# forms.py

class UserForgotPasswordForm(PasswordResetForm):
    email = forms.EmailField(required=True, max_length=254)

    class Meta:
        model = CustomUser
        fields = ('email',)

-

# my_app/templates/registration/password_reset_email.html

{% load i18n %}{% autoescape off %}
{% blocktrans %}You're receiving this email because you requested a password reset for your user account.{% endblocktrans %}

{% trans "Please go to the following page and choose a new password:" %}
{% block reset_link %}
{{ protocol }}://{{ domain }}{% url 'password-reset-link' uidb64=uid token=token %}
{% endblock %}
{% trans "Your username, in case you've forgotten:" %} {{ user.get_username }}

{% endautoescape %}

但是我收到以下错误：

Reverse for 'password-reset-link' with arguments '()' and keyword arguments '{'uidb64': b'MTI1', 'token': '4g9-f370fd6ee48d90a40b67'}' not found. 1 pattern(s) tried: ['api/v1/password/reset/?$']

知道为什么吗？我错过了什么？谢谢你的帮助。

Answer 1

在您的HTML中的网址中，您传递了token和uidb64：

{{ protocol }}://{{ domain }}{% url 'password-reset-link' uidb64=uid token=token %}

但是，在您的实际网址中，您没有引用token或uidb64：

url(r'^api/v1/password/reset/?$', PasswordResetView.as_view(), name='password-reset-link')

我建议您将网址更改为：

url(r'^api/v1/password/reset/(?P<uidb64>[0-9A-Za-z_\-]+)/(?P<token>[0-9A-Za-z]{1,13}-[0-9A-Za-z]{1,20})/$', PasswordResetView.as_view(), name='password-reset-link')

Answer 2

您的名为password-reset-link的网址不支持您发送的关键字参数uidb64和token。这些关键字参数不仅仅是额外的数据，它们需要匹配URL模式中的某个位置。

根据错误，您的网址格式为：

api/v1/password/reset/?$

为了支持您想要的内容，您需要将两个named arguments称为<uidb64>和<token>。例如：

api/v1/password/reset/(?P<uidb64>[a-zA-Z0-9]+)/(?P<token>[a-zA-Z0-9]+)/?$

您必须调整正则表达式以支持uidb64和令牌格式。
