Dango 2.2 使用关键字参数反转“激活”

Question

我在创建帐户并使用电子邮件中发送的链接激活帐户时遇到问题。该应用程序是用 Django 2.2 版本编写的。

单击激活链接后，我收到一条消息：

Reverse for 'activate' with keyword arguments '{'uidb64': '', 'token': ''}' not found. 1 pattern(s) tried: ['activate/(?P<uidb64>[^/]+)/(?P<token>[^/]+)/$']

urls.py 中的代码

path('activate/<uidb64>/<token>/', account.activate, name='activate'),

代码在views.py中，注册和激活链接的代码。注册就像 CBV，激活就像 FBV。

class Signup(View):
    def get(self, request):
        form = SignUpForm()
        return render(request, 'account/signup.html', {'form': form})

    def post(self, request):
        form = SignUpForm(request.POST)
        if form.is_valid():
            user = form.save(commit=False)
            user.is_active = False
            user.save()
            current_site = get_current_site(request)
            subject = 'Activate your Spotted account'
            message = render_to_string('account/account_activation_email.html', {
                'user': user,
                'domain': current_site.domain,
                'uid': urlsafe_base64_encode(force_bytes(user.pk)),
                'token': account_activation_token.make_token(user)
            })
            user.email_user(subject, message)
            return redirect('account_activation_sent')
        return render(request, 'account/signup.html', {'form': form})


def activate(request, uidb64, token):
    try:
        uid = force_text(urlsafe_base64_decode(uidb64))
        user = User.objects.get(pk=uid)
    except (TypeError, ValueError, OverflowError, User.DoesNotExist):
        user = None

    if user is not None and account_activation_token.check_token(user, token):
        user.is_active = True
        user.profile.email_confirmed = True
        user.save()
        login(request, user)
        return render(request, 'account/account_activation_email.html')
    else:
        return render(request, 'account/account_activation_invalid.html')

在 account/account_activation_email.html 中：

{% autoescape off %}
Hi {{ user.username }},

Please click on the link below to confirm your registration:

http://{{ domain }}{% url 'activate' uidb64=uid token=token %}
{% endautoescape %}

令牌.py

from django.contrib.auth.tokens import PasswordResetTokenGenerator
from django.utils import six


class AccountActivationTokenGenerator(PasswordResetTokenGenerator):
    def _make_hash_value(self, user, timestamp):
        return (
            six.text_type(user.pk) + six.text_type(timestamp) +
            six.text_type(user.profile.email_confirmed)
        )


account_activation_token = AccountActivationTokenGenerator()

Answer 1

如果您使用 Django 3.1 或更高版本，激活/密码重置机制对令牌使用 SHA-256 哈希算法。你的正则表达式太严格了。您应该根据文档使用路径而不是 url，如下所示。

path('reset/<uidb64>/<token>/', ...)

path('activate/<uidb64>/<token>/', ...)

Answer 2

您必须将tokenanduid作为上下文传递给render：

def activate(request, uidb64, token):
    ...

    context = {'uidb64':uidb64, 'token':token}
    return render(request, 'account/account_activation_email.html', context)
