you have to pass the request via context when you call the serializer inside the View
Or if you use get_serializer method, it will do that for u
https://stackoverflow.com/questions/42624104/django-rest-framework-keyerror-request related question
Mirco
it depends on the kind of view u have, the ListAPIView should already inject it via get_serializer_context
John
def post(self, request, sender,receiver):
if sender == request.user.id:
serializer = self.get_serializer(data=request.data)
serializer.is_valid(raise_exception=True)
serializer.save()
sender_message = Message.objects.filter(sender_id=request.user.id, receiver_id=receiver)
receiver_message = Message.objects.filter(sender_id=receiver, receiver_id=sender)
return Response({"Sender": MessageSerializer(instance=sender_message, many=True).data,
"Reciver": MessageSerializer(instance=receiver_message, many=True).data})
else:
return Response({'error': 'you are not allowed here'},
status=status.HTTP_400_BAD_REQUEST)
John
Is it required when I pass the serializer like this
John
In listapiview ??
Mirco
Is it required when I pass the serializer like this
MessageSerializer(instance=sender_message, many=True, context={'request': request}).data
John
Still the same issue

else:

It says the exception location is serializer.py , the line with user = self.context['request'].user
John
This is the way to get the current user in a serializer right
John
?
Mirco
This is the way to get the current user in a serializer right
yup but if the serializer has no context, it's a KeyError

the error is on GET or POST ?
paste the traceback inside pastebin
Mirco

https://pastebin.com/c89WCuif
with ListAPIView you have get_serializer_context to handle extra context for serializers, the defaults should already contain request
Mirco
?
John

paste the traceback inside pastebin
Now I got a new error TypeError at /messageview/2/1/

you don't have to do that inside the serializer
you have to handle the queryset inside get_queryset method of the view

Doragonsureiyā
can anybody help me html only loads, css dosnt
Don't ask meta questions like:
"Any user of $x here?"
"Anyone used technology $y?"
"Hello, I need help on $z!"
Just ask directly! The better you are at explaining the problem, the more likely you are to get help.
Asking smart questions
Mirco

Ask directly and explain the issue with details if you wanna a proper answer.
