Create token with different model than user in django - django

Question

I am trying to create an authentication token for my model called Person, but the Token table asks me for a user_id as a foreign key, is there any way I can create tokens with a different User model?
This is my Person model:
class Person(AbstractBaseUser):
first_name = models.CharField('Nombre', max_length = 100)
last_name = models.CharField('Apellido', max_length = 100)
username = models.CharField('Username', max_length = 50)
nickname = models.CharField('Nickname', max_length = 50, null = True)
gener = models.IntegerField('Genero')
phone = models.CharField('Teléfono', max_length = 13, null = True)
birtday = models.DateField('Cumpleaños', auto_now=False, auto_now_add=False, null = True)
address_id = models.IntegerField('Dirección', null = True)
address_birtday_id = models.IntegerField('Lugar de Nacimiento', null = True)
email = models.EmailField('Correo', max_length=254)
password = models.CharField('Password', max_length = 700)
photo = models.CharField('Foto', max_length=254, null = True)
about_me = models.CharField('Biografía', max_length = 1000, null = True)
active = models.IntegerField('Activo')
connected = models.IntegerField('Conectado')
person_type_id = models.IntegerField('Tipo', null = True)
created_at = models.DateTimeField(auto_now_add=True, null=True, blank=True)
updated_at = models.DateTimeField(auto_now=True, null=True, blank=True)
USERNAME_FIELD = 'username'
def __str__(self):
return '{0},{1}'.format(self.last_name, self.first_name)
This is my view:
class LoginPersonAPI(APIView):
def post(self, request):
serializer = LoginPersonSerializer(data = request.data)
if serializer.is_valid():
person = Person.objects.filter(username=serializer.validated_data['username'])
token = Token.objects.get_or_create(key = person[0].id)
if token:
return Response(token[0])
return Response(person[0].id, status = status.HTTP_201_CREATED)
else:
return Response(serializer.errors, status = status.HTTP_400_BAD_REQUEST)
This is my serializer:
class LoginPersonSerializer(serializers.Serializer):
username = serializers.CharField()
password = serializers.CharField()
def login(self, validate_data):
instance = Person
instance.username = validate_data.get("username")
instance.password = validate_data.get("password")
instance.find()
return instance
and this is the error
null value in column "user_id" violates not-null constraint
