如何在 Django 中序列化

Question

我在 Django 中有一个序列化程序如下：

class ListSerializer(serializers.HyperlinkedModelSerializer):
    vehicles = serializers.HyperlinkedRelatedField(
        view_name='asset-detail',
        many=True,
        read_only=True
    )

    class Meta:
        model = List
        fields = ('url', 'name', 'start', 'stop', 'state', 'vehicles')

我得到的结果如下：

[
    {
        "url": "http://127.0.0.1:8000/sales/api/v1/lists/3741/", 
        "name": "DEA 2017", 
        "start": "2017-03-09T10:00:00", 
        "stop": "2017-12-31T12:00:00", 
        "state": "OPEN", 
        "vehicles": [
            "http://127.0.0.1:8000/sales/api/v1/assets/134299/", 
            "http://127.0.0.1:8000/sales/api/v1/assets/154368/", 
            "http://127.0.0.1:8000/sales/api/v1/assets/154367/", 
            "http://127.0.0.1:8000/sales/api/v1/assets/154246/", 
            "http://127.0.0.1:8000/sales/api/v1/assets/155906/", 
            "http://127.0.0.1:8000/sales/api/v1/assets/155212/", 
            "http://127.0.0.1:8000/sales/api/v1/assets/154574/", 
            "http://127.0.0.1:8000/sales/api/v1/assets/155683/", 
            "http://127.0.0.1:8000/sales/api/v1/assets/153347/", 
            "http://127.0.0.1:8000/sales/api/v1/assets/153183/", 
            "http://127.0.0.1:8000/sales/api/v1/assets/153182/", 
            "http://127.0.0.1:8000/sales/api/v1/assets/153152/", 
            "http://127.0.0.1:8000/sales/api/v1/assets/153116/", 
            "http://127.0.0.1:8000/sales/api/v1/assets/154913/", 
            "http://127.0.0.1:8000/sales/api/v1/assets/152389/", 
            "http://127.0.0.1:8000/sales/api/v1/assets/153459/", 
            "http://127.0.0.1:8000/sales/api/v1/assets/153568/", 
            "http://127.0.0.1:8000/sales/api/v1/assets/153659/"
        ]
    }
]

如果我点击 vehicles 中的 url 之一，我会得到如下对象：

{
    "vin": "WVWZZZ6RZEY104640",
    "make": "VOLKSWAGEN", 
    "model": "POLO", 
    "fuel": "Diesel"
}

我想要的是使用对象而不是 url 来获得结果。

因此如下：

[
        {
            "url": "http://127.0.0.1:8000/sales/api/v1/lists/3741/", 
            "name": "DEA 2017", 
            "start": "2017-03-09T10:00:00", 
            "stop": "2017-12-31T12:00:00", 
            "state": "OPEN", 
            "vehicles": [
                {
                   "vin": "WVWZZZ6RZEY104123",
                   "make": "VOLKSWAGEN", 
                   "model": "POLO", 
                   "fuel": "Diesel"
                }, 
                {
                   "vin": "WVWZZZ6RZEY10452",
                   "make": "VOLKSWAGEN", 
                   "model": "Golf", 
                   "fuel": "Diesel"
                }, 
                {...},
                {...},
                {...},
                ....
            ]
        }
    ]

有什么建议吗？

P.S。我完全是初学者，请怜悯:)

Answer 1

您正在寻找已解释的嵌套序列化程序 there

Answer 2

我相信您确实有一个 Vehicle 模型来表示 Vehicle 属性。然后你可以为车辆创建序列化器并为你使用它 List Serializer 如下：

 class VehicleSerializer(serializers.ModelSerializer):
   """Serializer for vehicle"""

      class Meta:
         model = Vehicle



 class ListSerializer(serializers.HyperlinkedModelSerializer):
    vehicles = VehicleSerializer(many=true)

    class Meta:
        model = List
        fields = ('url', 'name', 'start', 'stop', 'state', 'vehicles')
