[Answered ]-How to save the current user for the created model object in Django rest framework

You can use permission decorator with IsAuthenticated permission to allow only the authenticated users as the following:

from rest_framework.decorators import api_view, permission_classes
from rest_framework.permissions import IsAuthenticated

@api_view(['POST'])
@permission_classes([IsAuthenticated])
def create(request):
if request.method == 'POST':
    serializer = ArticleSerializer(data = request.data)

    if serializer.is_valid():
        serializer.save()
        return Response(serializer.data, status=status.HTTP_201_CREATED)

return Response(serializer.data, status=status.HTTP_400_BAD_REQUEST)

The above code will allow only the authenticated users to use that view now to take the value of the user id from the logged-in user directly without sending it in the body request you can do the following:

from rest_framework import serializer
from .models import Article

class ArticleSerializer(serializers.ModelSerializer):

    class Meta:
        model = Article
        fields = '__all__'
        read_only_fields = ['author']

    def create(self, validated_data):
        # Get the authenticated user from the request
        user = self.context['request'].user

        # Add the authenticated user as the author of the article
        validated_data['author'] = user

        # Create the article with the updated data
        return super().create(validated_data)
