Django Rest Framework是所有者

Question

I'd like to create a field is_owner for my serializer which would return whether or not the object being serialized is owned by the user making the request. Something like:

"""Defines Some serializer with an owner"""
from rest_framework import serializers

class SomeSerializer(serializers.ModelSerializer):
    """Returns the is_owner field as a boolean"""
    is_owner = serializers.SerializerMethodField()

    class Meta:
        model = SomeModel
        fields = ('is_owner',)

 def get_is_owner(self, obj):
    """Will return True if the requesting user is the owner, else false"""
    return request.user.id == obj.user.id

Is this the way to do it? Should I be passing the request object to the serializer to make this work? Should I be testing this at the view level?

Thank you!

def get_is_owner(self, obj):
    """
    you can pass request in context
    """
    return self.context['request'].user.id == obj.user.id

when you call the serializer pass request in context like following code;

serializer = SomeSerializer(instance, context={'request': request, ...})
