Registration using e-mail, Django 2.0

I'm just a beginner, so i got some questions making my first project. I've got code in views:

def signup(request):
if request.method == 'POST':
    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)
        mail_subject = 'Активация'
        message = render_to_string('acc_active_email.html', {
            'user': user,
            'domain': current_site.domain,
            'uid':urlsafe_base64_encode(force_bytes(user.pk)),
            'token':account_activation_token.make_token(user),
        })
        print(message) # здесь я смотрю какое сообщение отправляю

        to_email = form.cleaned_data.get('email')
        email = EmailMessage(
                    mail_subject, message, to=[to_email]
        )
        email.send()
        return HttpResponse('Пожалуйста, подтвердите адрес электронной почты')
else:
    form = SignupForm()
return render(request, '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.save()
        login(request, user)
        # return redirect('home')
        return HttpResponse('Thank you for your email confirmation. Now you can login your account.')
    else:
        return HttpResponse('Activation link is invalid!')

This code is from urls:

from . import views
from django.urls import path

urlpatterns = [
    path('', views.signup, name='signup'),
    path('activate/?P<uidb64>[0-9A-Za-z_\-]+/(?P<token>[0-9A-Za-z]{1,13}-[0-9A-Za-z]{1,20})/$',
        views.activate, name='activate'),
]

The problem is that i always get invalid URL in my email. I think it is about new 'path' function, which may be used is 

<int:uidb64>

but not really sure. Thank for your help!

You can't use regexes like [0-9A-Za-z_\-]+ when you use path(). If you want to use regexes, then use re_path (which works the same as url() from older versions of Django).

When you use path(), you can use one of the built-in path converters. You can't use <int:uidb64>, because uidb can contain A-Za-z, hyphens, and underscores, not just digits.

For your uidb64 and token, I think slug is the most suitable of the path converters included in Django.

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

This will match slugs and tokens which your regex wouldn't allow, but this isn't a problem as long as your check_token method returns False for these invalid values and does not raise an error.
