How to set current user to user field in Django Rest Framework?

Question

I have the following code working perfectly. I can create a Post object from DRF panel by selecting an image and a user. However I want DRF to populate the user field by the currently logged in user.

models.py

class Post(TimeStamped):     user = models.ForeignKey(User)     photo = models.ImageField(upload_to='upload/')     hidden = models.BooleanField(default=False)     upvotes = models.PositiveIntegerField(default=0)     downvotes = models.PositiveIntegerField(default=0)     comments = models.PositiveIntegerField(default=0) 

serializers.py

class PostSerializer(serializers.ModelSerializer):     class Meta:         model = Post         fields = ['id', 'user', 'photo'] 

views.py

class PhotoListAPIView(generics.ListCreateAPIView):     queryset = Post.objects.filter(hidden=False)     serializer_class = PostSerializer     authentication_classes = (SessionAuthentication, BasicAuthentication)     permission_classes = (IsAuthenticated,) 

How can I do this?

Answer 1

Off the top of my head, you can just override the perform_create() method:

class PhotoListAPIView(generics.ListCreateAPIView):     ...     def perform_create(self, serializer):         serializer.save(user=self.request.user) 

Give that a shot and let me know if it works
