Using views to change DRF response - django

Question

I would like to alter the response from an API.
However, it does not alter the result properly. I get a KeyError: 'game'.
I am not sure why, as my API response (via URL) seems to have the value game in it. I may be getting confused with the JSON response, and the python object.
I have a sample of the API response below
results from API
{
"pk": 995,
"game": [
{
"name": "Finance",
"gamelevel": 3
},
{
"name": "Data",
"gamelevel": 1
}
]
},
views.py
class TagList(viewsets.ModelViewSet):
queryset = Task.objects.filter(game__isnull=False).all()
serializer_class = TagSortSerializer
def get_queryset(self):
test = self.queryset.values('title', 'game__name')
result = defaultdict(set)
for item in queryset:
parent = {'name': 'NoLevel_1'}
children = []
for game in item['game']:
if game['gamelevel'] == 1:
parent = game
else:
children.append((game['gamelevel'], game['name']))
result[parent['name']].update(children)
result = [
{
'name': parent,
'game_child': [
{'name': name, 'gamelevel': gamelevel} for gamelevel, name in games
],
'gamelevel': 1,
} for parent, games in result.items()
]
return result

You're using the values queryset method to get only a selection of fields from the model, and the only fields you've specified are title and tag__name. So you won't get game or any of the other keys you've used.
You certainly don't want to use values here in the first place; just do a normal query and access fields via dot lookup rather than dictionary.
