One way is answer from this https://stackoverflow.com/questions/24164160/adding-extra-data-to-django-rest-framework-results-for-entire-result-set

If it was a simple APIView - You can pass extra context dictionary to your serializer and then you can override the __init__ and/or to_representation of your serializer and access the passed context there.

for exa.

in your view:

serializer = MySerializer(queryset, context = {'user':request.user })

Your serializer:

class MySerializer(serializers.ModelSerializer):

def __init__(self, *args, **kwargs):

user = kwargs.get('context').get('user', None)

if user:

self.user = user

super(MySerializer, self).__init__(*args, **kwargs)

def to_representation(self, instance):

data = super().to_representation(instance)

if(hasattr(self, "user")):

data['user'] = self.user

return data
