如何将所需字段作为DRF序列化程序的json列表

Question

我正在努力消除简单的嵌套json。serializer.py

class CurrencyMasterSerializer(serializers.ModelSerializer):

    class Meta:
        model = CurrencyMaster
        fields = ["id", "name"]
{
        "id": 1,
        "name": "USD - United States Dollar"
    },
    {
        "id": 2,
        "name": "EUR - Euro Members"
    },
    {
        "id": 3,
        "name": "JPY - Japan Yen"
    },

这是邮递员给我的回复。但我预计输出如下，

{
    "country-codes": [
        {
            "id": 1,
            "name": "USD - United States Dollar"
        },
        {
            "id": 2,
            "name": "EUR - Euro Members"
        },
        {
            "id": 3,
            "name": "JPY - Japan Yen"
}]
}

我怎样才能做到这一点？

在您的视图中，在返回结果的地方，只需将其包装成所需的形式即可；

return Response({
    "country-codes": [response]
})

哪里

response = {
        "id": 1,
        "name": "USD - United States Dollar"
    },
    {
        "id": 2,
        "name": "EUR - Euro Members"
    },
    {
        "id": 3,
        "name": "JPY - Japan Yen"
    }
