Update django model database with ForeignKey by using serializer - python-3.x

Question

I have created a django model which includes a foreign key to a user as follows:
from authentication.models import User
from django.db import models
class Event(models.Model):
user = models.ForeignKey(User, on_delete=models.CASCADE, null=True)
dr_notice_period = models.IntegerField(blank=True, null=True)
dr_duration = models.IntegerField(blank=True, null=True)
dr_request = models.FloatField(blank=True, null=True)
My serializers.py file is as follows:
class EventSerializer(serializers.ModelSerializer):
user = UserSerializer(many=True, read_only=True)
class Meta:
model = Event
fields = ['user', 'dr_notice_period', 'dr_duration', 'dr_request']
What I need to do is to go to a url and with a POST request to upload the data to the database, but without specifically specifying the user.
My views.py is as follows:
from rest_framework.response import Response
from rest_framework.decorators import api_view
from rest_framework import status
from vpp_optimization.serializers import EventSerializer
#api_view(['POST'])
def event(request):
serializer = EventSerializer(data=request.data)
if serializer.is_valid():
instance = serializer.save(commit=False)
instance.user = request.user
instance.save()
return Response({"status": "success", "data": serializer.data}, status=status.HTTP_200_OK)
else:
return Response({"status": "error", "data": serializer.errors}, status=status.HTTP_400_BAD_REQUEST)
As I study I thought that by using commit=False in save would solve the problem, but I am getting the following error:
'commit' is not a valid keyword argument to the 'save()' method. If you need to access data before committing to the database then inspect 'serializer.validated_data' instead. You can also pass additional keyword arguments to 'save()' if you need to set extra attributes on the saved model instance. For example: 'serializer.save(owner=request.user)'.'
Is there a better way to do what I intent to do?

Answer 1

You pass the user as parameter, so:
if serializer.is_valid():
instance = serializer.save(user=request.user)
return Response({'status': 'success', 'data': serializer.data}, status=status.HTTP_200_OK)
Note: It is normally better to make use of the settings.AUTH_USER_MODEL [Django-doc] to refer to the user model, than to use the User model [Django-doc] directly. For more information you can see the referencing the User model section of the documentation.
