Pythonanywhere django.urls.exceptions.NoReverseMatch：使用关键字参数反转“激活”

Question

我在 pythonanywhere 工作并且我已经运行了一个注册脚本 - 本地它在 pythonanywhere 中没有问题我得到这个错误

2020-09-13 15:37:43,507: Internal Server Error: /signup1/

如果发现错误出现在这一行的视图中：

text_body = render_to_string('acc_active_email.txt', merge_data)

在我的本地主机上它可以正常工作

views.py

def signup1(request):
    if request.method == 'POST':
        form = werkforms.UserCreationform(request.POST)
        if form.is_valid():
            username = form.cleaned_data.get('username')
            email = form.cleaned_data.get('email')
            raw_password = form.cleaned_data.get('password1')
            Firmennamen = form.cleaned_data.get('Firmennamen')
            Street = form.cleaned_data.get('Street')
            plzort = form.cleaned_data.get('plzort')

            user = User.objects.create_user(username, email, raw_password)
            user.is_active = False
            user.save()
            userid = user.id
            UserID = User.objects.get(id=userid)
            current_site = get_current_site(request)
            print("hallo")


            merge_data = {
                'user': user,
                'domain': current_site.domain,
                'uid': force_text(urlsafe_base64_encode(force_bytes(user.pk))),
                'token': account_activation_token.make_token(user),
            }
            print(merge_data) 
            text_body = render_to_string('acc_active_email.txt', merge_data)

            --- some more code --- 

            test = "das ist response"

    return HttpResponse(test, content_type="text/html")

acc_active_email.txt

Answer 1

您也应该在激活函数中使用上下文参数：

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

有些人建议在uid key中使用decode() func，但我认为应该只是：

'uid': urlsafe_base64_encode(force_bytes(user.pk))

主要问题在于您的应用程序的网址（包括激活视图）。你应该使用蛞蝓：

path('activate/<slug:uidb64>/<slug:token>/', views.activate, name='activate')

如果您只使用 url，请不要忘记导入路径

from django.urls import path

Answer 2

在你必须设置的网址中

path('activate/<slug:uidb64>/<slug:token>/',
         activate, name='activate'),

并且不要忘记从视图激活中导入 url

from myapp.views import (
    activate
    )
