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
