ObtainAuthToken: "non_field_errors": [ "Unable to log in with provided credentials."

[Abdullah Nafees]

Hey guys,

ObtainAuthToken is not returning Token for provided username and password. My requirement is to create a custom user so I am not using the default one. I have already tried the solution provided here. I am pasting my code below:

managers.py

from django.contrib.auth.models import BaseUserManager

class CustomUserManager(BaseUserManager):

def create_user(self, validated_data):

if not validated_data["email"]:

raise ValueError("User must have a unique username.")

user = self.model(

email=self.normalize_email(validated_data["email"]),

username=validated_data["username"],

)

user.set_password(validated_data["password"])

user.save(using=self._db)

return user

serializers.py

from rest_framework import serializers

from .models import CustomUser

class CustomUserSerializer(serializers.ModelSerializer):

class Meta:

model = CustomUser

fields = "__all__"

class UserLoginSerializer(serializers.ModelSerializer):

class Meta:

model = CustomUser

fields = ["username", "email", "password"]

extra_kwargs = {"password": {"write_only": True}}

views.py

from rest_framework.authtoken.models import Token

from rest_framework.authtoken.views import ObtainAuthToken

from rest_framework.generics import CreateAPIView, ListAPIView

from rest_framework.response import Response

from .models import CustomUser

from .serializers import CustomUserSerializer, UserLoginSerializer

class ListUsers(ListAPIView):

queryset = CustomUser.objects.all()

serializer_class = CustomUserSerializer

class RegisterUser(CreateAPIView):

queryset = CustomUser.objects.all()

serializer_class = CustomUserSerializer

class LoginView(ObtainAuthToken):

def post(self, request, *args, **kwargs):

serializer = UserLoginSerializer(data=request.data)

serializer.is_valid(raise_exception=True)

user = serializer.validated_data["username"]

token, created = Token.objects.get_or_create(user=user)

return Response({"token": token.key, "user_id": user.pk, "email": user.email})

Response

{

"non_field_errors": [

"Unable to log in with provided credentials."

]

}
