激活用户Django 2.1

Question

我在开发Django应用程序时遇到了一个问题。我需要注册用户并发送链接以激活用户帐户，但是当我点击链接时它不会激活帐户，它只会返回到我的主页。如何激活用户帐户？

我的urls.py代码：

from django.contrib import admin
from django.urls import path
from contas.views import home, nova_transacao, update, delete, notSuper, signUp, activation_sent, activate

urlpatterns = [
    path('admin/', admin.site.urls),
    path('', home, name='url_home'),
    path('update/<int:pk>/', update, name='url_update'),
    path('delete/<int:pk>/', delete, name='url_delete'),
    path('403/', notSuper, name='url_notSuper'),
    path('form/', nova_transacao, name='url_novaTransacao'),
    path('signup/', signUp, name='url_signUp'),
    path('signup/activation_sent/', activation_sent, name='url_activationSent'),
    path('activate/<slug:uidb64>/<slug:token>', activate, name='activate'),

]

我的views.py代码：

from django.contrib.auth import login
from django.contrib.auth.models import User
from django.contrib.sites.shortcuts import get_current_site
from django.http import HttpResponseRedirect, HttpResponse
from django.shortcuts import render, redirect
from django.template.loader import render_to_string
from django.urls import reverse
from django.utils.encoding import force_bytes, force_text
from django.utils.http import urlsafe_base64_encode, urlsafe_base64_decode
from contas.tokens import account_activation_token
from .models import Transacao
from .form import TransacaoForm, SignUpForm
from django.core.mail import send_mail
from django.conf import settings

import datetime, time

# Create your views here.


def home(request):
    data = {}
    data["transacoes"] = Transacao.objects.all()
    data["now"] = datetime.datetime.now()
    return render(request, "contas/home.html", data)


def nova_transacao(request):
    form = TransacaoForm(request.POST or None)
    if form.is_valid():
        if request.user.is_authenticated:
            if request.user.is_superuser:
                form.save()
                return redirect('url_home')
            else:
                return redirect('url_notSuper')
        else:
            return redirect('url_login')
    return render(request, "contas/form.html", {"form": form})


def update(request, pk):
    transacao = Transacao.objects.get(pk=pk)
    form = TransacaoForm(request.POST or None, instance=transacao)
    if form.is_valid():
        if request.user.is_authenticated:
            if request.user.is_staff:
                form.save()
                return redirect('url_home')
            else:
                return redirect('url_notSuper')
        else:
            return redirect('url_login')
    return render(request, "contas/form.html", {"form": form, "transacao": transacao})


def delete(request, pk):
    transacao = Transacao.objects.get(pk=pk)
    if request.user.is_authenticated:
        if request.user.is_staff:
            transacao.delete()
            return redirect('url_home')
        else:
            return redirect('url_notSuper')
    else:
        return redirect('url_login')


def signUp(request):
    if request.method == 'POST':
        form = SignUpForm(request.POST or None)
        if form.is_valid():
            user = form.save(commit=False)
            user.is_active = False
            user.save()
            current_site = get_current_site(request) 
            subject = 'Ative sua conta Controller-Gastos'
            uid = urlsafe_base64_encode(force_bytes(user.pk)).decode()
            token = account_activation_token.make_token(user)
            activation_link = "{0}/uid={1}/token={2}".format(current_site, uid, token)
            email_from = settings.EMAIL_HOST_USER
            to_email = [form.cleaned_data.get('email')]
            message = "Hello {0},
 {1}".format(user.username, activation_link)
            # send_mail(subject, message, email_from, to_email)
            return HttpResponse('Please confirm your email address to complete the registration using the link below<br>' + message)
    else:
        form = SignUpForm()
    return render(request, 'contas/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 HttpResponse('Account activated successfully')
        # time.sleep(5)
        # return redirect('url_home')
    else:
        return render(request, 'contas/account_activation_invalid.html')



def notSuper(request):
    return render(request, 'contas/notSuper.html')

def activation_sent(request):
    return render(request, 'contas/activation_sent.html')

我的contas/activate.html代码：

{% autoescape off %}
Hi {{ user.username }},
Please click on the link below to confirm your registration:

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

我的models.py代码：

from django.db import models
from django.utils.timezone import now
from django.contrib.auth.models import User
from django.db.models.signals import post_save
from django.dispatch import receiver

Class Profile(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE)
bio = models.TextField(max_length=500, blank=True)
location = models.CharField(max_length=30, blank=True)
email_confirmed = models.BooleanField(default=False)

@receiver(post_save, sender=User)
def update_user_profile(sender, instance, created, **kwargs):
    if created:
        Profile.objects.create(user=instance)
    instance.profile.save()

目前，当我注册一个新用户时，我获得了带有激活链接的HttpResponse，但它什么也没做。

Page not found (404)
Request Method:     GET
Request URL:    http://0.0.0.0:8000/uid%3DNTY/token%3D4ze-3028a8e050e89eed45a1

Using the URLconf defined in controle_gastos.urls, Django tried these URL patterns, in this order:

    admin/
    [name='url_home']
    update/<int:pk>/ [name='url_update']
    delete/<int:pk>/ [name='url_delete']
    403/ [name='url_notSuper']
    form/ [name='url_novaTransacao']
    signup/ [name='url_signUp']
    signup/activation_sent/ [name='url_activationSent']
    activate/<slug:uidb64>/<slug:token> [name='activate']

The current path, uid=NTY/token=4ze-3028a8e050e89eed45a1, didn't match any of these.
