Django REST serialize single model instance

Question

I'm trying to serialize a model instance of type Shift but I'm getting an error.

'Shift' object has no attribute 'get'

shift = models.Shift.objects.get(pk=8)
ser = serializers.ShiftSerializer(many=False, data=shift)
ser.is_valid()

ShiftSerializer is a ModelSerializer. This works if I get the shift using filter and all and many=True.

Solution:

shift = models.Shift.objects.get(pk=8)
ser = serializers.ShiftSerializer(shift)

Answer 1

The data parameter is for deserializing, not serializing. You should just pass the model instance as a positional arg.

obj = serializers.ShiftSerializer(shift)

Note there's no need to specify many=False, that's the default. Also, it doesn't make sense to call is_valid() on the serializer you've constructed from a model instance; again, that's for deserialization.
