You have the wrong placement:

class MyModelSerializer(serailizers.ModelSerializer):         
    class Meta:
       model = MyModel
       fields = "__all__"
    hrs = serializers.SerializerMethodField()

    def get_hrs(self, obj):
       datetime = SomeModel.objects.filter(id=obj.id).last().datetime
       now = datetime.now()
       return (now - datetime).total_seconds() // 3600
