如何获取嵌套值并将其链接到将列传递到材料表的字段

Question

我正在尝试创建一个表，并且我嵌套了如下数据：

[{
id: 24,
name: "DANIEL TSUTOMU OBARA",
number: "134",
phone: "11111111111",
rg: "4034092666",
EmployeeStatus: {
createdAt: "2019-08-07T14:38:52.576Z"
description: "Documentos rejeitados"
id: 3
updatedAt: "2019-08-07T14:38:52.576Z"
},
Sector: {
id: 2,
name: "Controladoria"
}
}]

并有这个结构列表：

columns: [
{ title: "Nome", field: "name" },
{ title: "CPF", field: "cpf" },
{ title: "Função", field: "FunctionId", lookup: {} },
{
title: "Setor",
field: "SectorId",
lookup: {}
},
{
title: "Status",
field: "EmployeeStatus", <------- I want to get description here
editable: "never"
}
],

然后，我需要将这些列传递到我的材料表中，如下所示：

<MaterialTable
columns={state.columns}
data={state.data}
title=""
icons={tableIcons}
editable={{
onRowAdd: newData => createInstructor(newData),
onRowUpdate: async (newData, oldData) =>
updateInstructor(newData, oldData),
onRowDelete: oldData => deleteInstructor(oldData)
}}
/>

那么，我怎样才能将嵌套数据访问到列字段中呢？

谢谢！

Answer 1

请找到以下解决方案。 我希望数据也有其他对象，因此找到第一个具有可用键的对象。

let data = [{
id: 24,
name: "DANIEL TSUTOMU OBARA",
number: "134",
phone: "11111111111",
rg: "4034092666",
EmployeeStatus: {
createdAt: "2019-08-07T14:38:52.576Z",
description: "Documentos rejeitados",
id: 3,
updatedAt: "2019-08-07T14:38:52.576Z"
},
Sector: {
id: 2,
name: "Controladoria"
}
}]
let columns = [
{ title: "Nome", field: "name" },
{ title: "CPF", field: "cpf" },
{ title: "Função", field: "FunctionId", lookup: {} },
{
title: "Setor",
field: "SectorId",
lookup: {}
},
{
title: "Status",
field: "EmployeeStatus",
editable: "never"
}
];

let columnToUpdate = columns.find(obj => obj.title==="Status"); //find the column in columns array
let desc = data.find(obj => Object.keys(obj).includes('EmployeeStatus')).EmployeeStatus.description; // get description
columnToUpdate.field = desc; // mutate the object
console.log(columns);

我只是决定使用查找功能并暂时以这种方式解决。

const [state, setState] = useState({
columns: [
{ title: "ID", field: "id", editable: "never" },
{ title: "Nome", field: "name" },
{ title: "CPF", field: "cpf" },
{ title: "Função", field: "FunctionId", lookup: {} }, // 3
{
title: "Setor",
field: "SectorId",
lookup: {}
}, // 4
{
title: "Status",
field: "EmployeeStatusId",
lookup: {},
editable: "never"
}, // 5
]});
....
await api
.get(`/employee-status`)
.then(result => {
status = formatSectors(state, result, 5);
})
.....
const formatSectors = (state, result, position) => {
let columns = state.columns;
const indexColumnSector = 4;
columns[position].lookup = result.data.rows.reduce(
(accumulator, currentValue) => {
accumulator[currentValue.id] =
position === indexColumnSector
? currentValue.name
: currentValue.description;
return accumulator;
},
{}
);
return columns;
};
