JWT Token authentication - generate token - django-rest-framework

Question

I have created a login screen which uses a username and password to login. I have a jwt authentication but I'm getting a bit confused because I have two login urls and I want only one. The jwt url is providing me the token meanwhile the other one that I have created myself I can login but no token is getting generated. This is my code:
serializers.py
class UserLoginSerializer(ModelSerializer):
token = CharField(allow_blank=True, read_only=True)
username = CharField(required=False, allow_blank=True)
class Meta:
model = User
fields = [
'username',
'password',
'token',
]
extra_kwargs = {"password":{"write_only": True}}
def validate(self, data):
user = authenticate(**data)
if user:
if user.is_active:
data['user'] = user
return data
raise exceptions.AuthenticationFailed('Account is not activated')
raise exceptions.AuthenticationFailed('User is not active')
def validate(self, data):
user_obj = None
username = data.get("username", None)
password = data["password"]
if not username:
raise ValidationError("A username is required")
user = User.objects.filter(
Q(username=username)
).distinct()
if user.exists() and user.count() == 1:
user_obj = user.first()
else:
raise ValidationError("This username is not valid")
if user_obj:
if not user_obj.check_password(password):
raise ValidationError("Incorrect credentials, please try again")
data["token"] = "SOME RANDOM TOKEN"
return data
views.py
class UserLoginAPIView(APIView):
permission_classes = [AllowAny]
serializer_class = UserLoginSerializer
def post(self, request, *args, **kwargs):
data = request.data
serializer = UserLoginSerializer(data=data)
if serializer.is_valid(raise_exception=True):
new_data = serializer.data
return Response(new_data, status=HTTP_200_OK)
return Response(serializer.errors, status=HTTP_400_BAD_REQUEST)

You can re-write your login serializer like this:
from rest_framework_jwt.serializers import JSONWebTokenSerializer
class SignInJWTSerializer(JSONWebTokenSerializer):
def validate(self, attrs):
email = attrs.get('email')
password = attrs.get('password')
if email is None or password is None:
message = 'Must include email and password'
raise serializers.ValidationError({'message': message})
...
And in url:
from rest_framework_jwt.views import ObtainJSONWebToken
path('login/', ObtainJSONWebToken.as_view(serializer_class=serializers.SignInJWTSerializer), name='login'),
also remove view class
