Early detecting invalid password reset tokens

When there is need to check if password reset token is still valid without actually resetting the password it is possible to approach the problem like so:

from django.contrib.auth.tokens import default_token_generator
from rest_framework import generics, permissions, status
from rest_framework.response import Response

from djoser import serializers

class PasswordTokenCheckView(generics.CreateAPIView):
    permission_classes = (
    token_generator = default_token_generator
    serializer_class = serializers.UidAndTokenSerializer

    def post(self, request, *args, **kwargs):
        serializer = self.get_serializer(data=request.data)
        headers = self.get_success_headers(serializer.data)
        return Response(serializer.data, status=status.HTTP_200_OK, headers=headers)
