How to add current user into a field in django model serializer

I am developing an application in django-rest-framework. Following is my serializer:

class MySerializer(serializers.HyperlinkedModelSerializer):
    class Meta:
        model = My
        fields = ('user','title','description')

The problem is that when I run it, it asks for the user to be selected like this:

enter image description here

I want that whichever user is logged in, he should be added to user field automatically. In django website development, I used to do it using request.user but how do I do it in django rest framework?

If you extend django view generic classes then you can add in views.py

from rest_framework.permissions import IsAuthenticate

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

And then in serializers.py

class MySerializer(serializers.HyperlinkedModelSerializer):
    class Meta:
        model = My
        fields = ('user','title','description')
        read_only_fields = ('user',) # Add this

You would do something like the class 

MySerializer(serializers.HyperlinkedModelSerializer):
    user = serializers.ReadOnlyField()
    class Meta:
        model = My
        fields = ('user','title','description')

When you call the serializer, you just add the current user into the serializer, either in views.py or in serializer create method.

  1. In views.py

    serializer.save(user=request.user)

  2. In serializer create method

    def create(self, validated_data): validated_data['user'] = request.user.id obj = ExampleModel.objects.create(**validated_data) return obj

A default class that can be used to represent the current user. In order to use this, the 'request' must have been provided as part of the context dictionary when instantiating the serializer.

owner = serializers.HiddenField(
    default=serializers.CurrentUserDefault()
)

More details here: http://www.django-rest-framework.org/api-guide/validators/#currentuserdefault

Hope this will help
