django - 如何在 Django REST Framework 中返回自定义 JSON 输出

Question

我正在尝试返回具有以下结构的自定义 json

[ { 
'yesterday': [{'teams': "team a -team b", 'start_time': "0: 11", 'pick': "X2", 'score': "1:4", 'odds': 1.25, 'won_or_lost': "won", 'date': "2019-01-8"}],

'today': [{'teams': "team a -team b", 'start_time': "0: 11", 'pick': "X2", 'score': "1:4", 'odds': 1.25, 'won_or_lost': "won", 'date': "2019-01-8"}],

'tomorrow': [{'teams': "team a -team b", 'start_time': "0: 11", 'pick': "X2", 'score': "1:4", 'odds': 1.25, 'won_or_lost': "won", 'date': "2019-01-8"}]
}]

以下是我的代码:

序列化程序.py

class GamesSerializer(serializers.Serializer):
    class Meta:
        model = AllGames
        fields = ('teams', 'start_time', 'pick',
                  'score', 'odds', 'won_or_lost', 'date')


class GamesViewSet(viewsets.ModelViewSet):
    today_date = date_picker

    yesterday = AllGames.objects.filter(
        date=today_date(-1)).order_by('start_time', 'teams')
    today = AllGames.objects.filter(
        date=today_date(0)).order_by('start_time', 'teams')
    tomorrow = AllGames.objects.filter(
        date=today_date(1)).order_by('start_time', 'teams')

    queryset = [yesterday, today, tomorrow]
    serializer_class = GamesSerializer

电流输出

[
    {},
    {},
    {}
]

如何修改我的 GamesSerializer 返回如上所示的自定义输出。

Answer 1

您可以从 DRF ModelViewSet 转换您的响应类至 ViewSet .
然后你可以在返回响应之前进一步解析你的数据，通过覆盖 retrieve
