NoReverseMatch

[josephlee94]

I'm trying your email verification on my site, but I get this error:

NoReverseMatch
Reverse for 'activate' with keyword arguments '{'uidb64': b'MTM', 'token': '52d-53339dd970c622ae0d32'}' not found. 1 pattern(s) tried: ['accounts/activate/(?P[0-9A-Za-z_\-]+)/(?P[0-9A-Za-z]{1,13}-[0-9A-Za-z]{1,20})/$']

The error seemed to be at:

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

I'm getting the same problem...
django.urls.exceptions.NoReverseMatch: Reverse for 'activate' with keyword arguments '{'uidb64': b'MTE', 'token': '54r-56fbea658aa4822ce6b3'}' not found. 1 pattern(s) tried: ['activate/(?P[0-9A-Za-z_\-]+)/(?P[0-9A-Za-z]{1,13}-[0-9A-Za-z]{1,20})/$']

How did you solve it?

if you use django version 2.0 or above, you should use decode() after encoding the uid. As you can see through this code like :

message = render_to_string('account_activation_email.html', {
                'user': user,
                'domain': current_site.domain,
                'uid': urlsafe_base64_encode(force_bytes(user.pk)).decode(),
                'token': account_activation_token.make_token(user),
            })

Or you can use force_text that compatible with django version 1.11, 2.0 or higher. May it help you

i used this solution 'uid': urlsafe_base64_encode(force_bytes(user.pk)).decode(), and now i have an 'str' object has no attribute 'decode'
what to do?

[UngeheurenUngeziefer]

There is no need to use decode() function here, it should be just:
'uid': urlsafe_base64_encode(force_bytes(user.pk))

You should use context args in activation function as well:

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

And the main problem is in the urls of your app that including activation view. You should use slug:
path('activate/<slug:uidb64>/<slug:token>/', views.activate, name='activate')
and don't forget to import path if you are using only urls
from django.urls import path

I’m trying what you propose but it gives me another problem

my views.py

class ActivateAccount(View):

def get(self, request, uidb64, token, *args, **kwargs):
    context = {
        'uidb64': uidb64,
        'token': 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)
        messages.success(request, 'Your account have been confirmed.')
        return render(request, 'password_reset_form.html', context)

    else:
        messages.warning(request, 'The confirmation link was invalid, possibly because it has already been used.')
        return redirect('home')
