使用Django + Django Rest框架的随机字符生成器查询

Question

我已经创建了一个“角色起源”表，我想对该表运行查询，该查询将返回“三个选择”。每个选择中都有两个随机的Character Origins。

我目前正在使用Django和DRF构建我的API，我尝试使用Django-rest-framework-tricks中的嵌套序列化器，但失败了，现在，我认为最好的选择是使用比Djangos更好的查询ORM可以做到。

Serializers.py

class OriginsNestedSerializer(serializers.ModelSerializer):

    class Meta:
        model = Origin
        fields = (
            'id',
            'origin',
            'ability',
            'skill',
            'bonus',
            'ac',
            'fort',
            'ref',
            'will',
            'defense',
            'lvl_1',
            'lvl_2_or_6',
            'novice',
            'utility',
            'expert',
        )
        read_only_fields = ['id', ]
        nested_proxy_field = True


class ChoiceCharacterCreationSerializer(serializers.ModelSerializer):
    origin_primary = OriginsNestedSerializer()
    origin_secondary = OriginsNestedSerializer()

    class Meta:
        model = Origin
        fields = (
            'origin_primary',
            'origin_secondary',
        )
        nested_proxy_field = True


class ChoicesSerializer(serializers.ModelSerializer):
    choice = ChoiceCharacterCreationSerializer()

    class Meta:
        model = Origin
        fields = (
            'choice',
        )

Views.py

class CreateACharacterViewSet(viewsets.ModelViewSet):
    serializer_class = serializers.ChoicesSerializer
    queryset = models.Origin.objects.order_by('?')[:3]

我的结果是这个...

                "expert": "TRAMPLE - Encounter ...."
            }
        }
    }
]

我想要的是这样的三个选择，每个选择中有两个彼此不同的随机起源。

我认为这需要完成。

class CreateACharacterViewSet(viewsets.ModelViewSet):
    serializer_class = serializers.OriginSerializer
    queryset = models.Origin.objects.raw('SELECT * ...")
