如何获取 link 嵌套值以将列传递给 Material Table

Question

我正在尝试创建一个 table 并且我有这样的嵌套数据：

[{
  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"
  }
}]

并具有此结构列 table:

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，我需要像这样将这些列传递到我的 Material-table 中：

<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，如何将嵌套数据访问到列字段中？

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密钥的对象。

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);

我只是决定暂时使用查找功能并以这种方式求解。

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;
  };
