How to push data in a model whose one column is a forign key Django Rest Framework?

Question

I’m trying to assign data against specific user using DRF but getting some strange errors. I searched this problem a lot but not able to find any solution.

model.py

class Category(TrackingModels):
    name =models.CharField(default='Learning',max_length=150,unique=True,null=False)
    person=models.ForeignKey(to=User,on_delete=models.CASCADE)
    def __str__(self):
         return self.name

serializer.py

class CategorySerializer(ModelSerializer):
    person = serializers.PrimaryKeyRelatedField(read_only=True)
    class Meta:
        model=Category
        fields=('id','name','person')

views.py

class CategoryAPIView(CreateAPIView):
    serializer_class=CategorySerializer
    permission_classes=(IsAuthenticated,)

    def post(self,request):
        data={
            "person":request.user.id,
            "name":request.data.get('category')
        }
        serializer=CategorySerializer(data=data)
        if serializer.is_valid():
            serializer.save()
            return Response({"message":"Category is created sucessfully!"},status=status.HTTP_201_CREATED)
        return Response(serializer.errors,status=status.HTTP_400_BAD_REQUEST)

Here is Postman request:

You can use the below serializer:

#import 
from django.contrib.auth import get_user_model 
from rest_framework import serializers

UserModel = get_user_model()
class CategorySerializer(ModelSerializer):
    person = serializers.SlugRelatedField(queryset=UserModel.objects.all(), slug_field="id")
    class Meta:
       model=Category
       fields=('id','name','person')
