Django REST - JSON API 结果按键列出

Question

我有一个使用 Django Rest Framework 制作的非常基本的 API，输出如下：

[
{
"name": "John",
"city": "chicago",
"age": "22"
},
{
"name": "Gary",
"city": "florida",
"age": "35"
},
{
"name": "Selena",
"city": "vegas",
"age": "18"
}
]

我想将其转换为以下格式，以简化其在图表中的数据的使用。

{
"name": ["John", "Gary", "Selena"]
"city": ["chicago", "vegas", "florida"]
"age": ["22", "35", "18"]
}

1. 有没有一种简单的方法可以在Javascript中完成(和Python只是出于好奇(？

阿拉伯数字。可以通过调整 DRF 中的序列化程序或视图集来主动解决此问题吗？

Answer 1

Javascript 版本：

const data = [
{
name: 'John',
city: 'chicago',
age: '22',
},
{
name: 'Gary',
city: 'florida',
age: '35',
},
{
name: 'Selena',
city: 'vegas',
age: '18',
},
];
const result = Object.keys(data[0]).reduce((obj, key) => {
obj[key] = data.map(_ => _[key]);
return obj;
}, {});
console.log(result);

Answer 2

在 Python 中，你可以这样做：

data = [
{
"name": "John",
"city": "chicago",
"age": "22"
},
{
"name": "Gary",
"city": "florida",
"age": "35"
},
{
"name": "Selena",
"city": "vegas",
"age": "18"
}
]
result = {}
for key in data[0]:
result[key] = []
for entry in data:
for key in entry:
result[key].append(entry[key])
print(result)

Answer 3

检查这个

data = [
{
"name": "John",
"city": "chicago",
"age": "22"
},
{
"name": "Gary",
"city": "florida",
"age": "35"
},
{
"name": "Selena",
"city": "vegas",
"age": "18"
}
]
output = []
name = []
city = []
age = []
for i in data:
name.append(i['name'])
city.append(i['city'])
age.append(i['age'])
output.append({"name":name,"city":city,"age":age})
print(output)
