django - Key error 'request' in serializer -

-

i'm trying current user in serializer, evaluate condition (did user post?), this answer tried doesn't seem work:

def current_user(self):     return self.context['request'].user  class postserializer(serializers.modelserializer):     liked = serializers.serializermethodfield()      def get_liked(self, obj):         return str(current_user(self))      class meta:         model = track         fields = ('foo', 'liked')

and simple view:

@api_view(['get']) def post_item(request, pk):         serializer = postserializer(post)         return response(serializer.data)

when trying get_liked error raised:

keyerror @ /api/posts/1

'request'

am missing here?

you can send context view serializer this:

@api_view(['get']) def post_item(request, pk):     serializer = postserializer(track, context={'request': request})     return response(serializer.data)
