python之如何在 Django 中序列化

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 中的其中一个 url，我会得到如下对象:

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

我想要的是通过对象而不是 url 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？
