数据网格组件要求所有行都具有唯一的“id”属性

Question

我知道我必须使用 getRowId，但是我该如何使用它statId呢id？它是独一无二的。id或者为它们每个人生成一个属性？

错误：MUI：数据网格组件要求所有行都具有唯一的id属性。或者，您可以使用getRowIdprop 为每行指定一个自定义 id。rows 属性中提供了没有 id 的行：{"statId":813183,"teamId":3,"season":2021,"name":"Atlanta Hawks","team":"ATL","wins" ：41，“损失”：31，“fieldGoalsMade”：3492.1，“fieldGoalsAttempted”：7468.1，“fieldGoalsPercentage”：55.6，“twoPointersMade”：2427.9，“twoPointersAttempted”：4612.1，“twoPointersPercentage”：62.5，“ ThreePointersMade”：1064.2 ，“ ThreePointersAttempted”：2856，“ ThreePointersPercentage”：44.3，“ freeThrowsMade”：1684.8，“ freeThrowsAttempted”：2074.8，“ freeThrowsPercentage”：96.5，“进攻篮板”：903.6，“防守篮板”：3002.2，“篮板”：3905.9，“助攻”:2065.3、“抢断”:598.1、“封堵投篮”:405.4、“失误”:1086.7、“个人犯规”:1655.1、“得分”:9733.2、“双打”:120.1、“三双”:1.4}

Answer 1

您可以在道具中使用它DataGrid：

<DataGrid getRowId={(row) => row.statId} />

Answer 2

对于此错误，请记住迭代将继续运行keys以充当每行的唯一标识符。该getRowId属性希望从行中推断出唯一的 id。

这是一个示例解决方案：

const columns: GridColDef[] = [
      { salary:53025, first_name:"Don" },
      { salary:63026, first_name:"Ted" },
      { salary:73027, first_name:"Bill" },
      { salary:83028, first_name:"Al" },
      { salary:23022, first_name:"Biff" },
   ];

   return (
      <div style={{ height: 300, width: "100%" }}>
         <DataGrid
            rows={rows}
            columns={columns}
            getRowId={(row: any) =>  row.first_name + row.salary}
         />
      </div>

或者如果你仍然有按键冲突，你可以尝试这样的事情

function generateRandom() {
    var length = 8,
        charset = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789",
        retVal = "";
    for (var i = 0, n = charset.length; i < length; ++i) {
        retVal += charset.charAt(Math.floor(Math.random() * n));
    }
    return retVal;
}

   return (
      <div style={{ height: 300, width: "100%" }}>
         <DataGrid
            rows={rows}
            columns={columns}
            getRowId={(row: any) =>  generateRandom()}
         />
      </div>

Answer 3

如果您使用 MongoDB，则应包含此行 getRowId={(row) => row._id} ，因为 MongoDB 的 ID 名为 _id，这将查找 _id 选项并选择它作为唯一 ID

Answer 4

我从数据库 MongoDB 获取数据，所以这对我有用

  <DataGrid
    rows={usersData}
    disableSelectionOnClick
    columns={columns}
    pageSize={8}
    checkboxSelection
    getRowId={(row) => row._id}
    >
