将业务数据从 UI5 导出到 Excel

Export business data from UI5 to Excel

我有一个 table,其中包含产品详细信息,例如 IDdescriptionprice 等。我正在尝试将这些数据导出到 Excel.

问题

如果我只做 getModel("A"),然后绑定 而非 嵌套的“A”的几个属性,则 excel 可以正常下载。但是如果有任何其他结构,我试图访问,例如 getModel("A").getProperty("/Person/PersonFullName"),它将使 列空白

{ // Controller
  onExport: function() {
    var aCols, aProducts, oSettings;
    aCols = this.createColumnConfig();
    aProducts = this.getView().getModel("A"); // A has nested/deep entities
    oSettings = {
      workbook: { columns: aCols },
      dataSource: aProducts
    };
    var oSpreadsheet = new Spreadsheet(oSettings); // required "sap/ui/export/Spreadsheet"
    oSpreadsheet.build();
  },            

  createColumnConfig: function() {
    return [
      {
        label: 'Product ID',
        property: 'name'
      },
      {
        label: 'Category',
        property: 'BillTo/BillToName', //Not able to get this property
      }
    ];
  },

}

根据 API reference of sap/ui/export/SpreadsheetdataSource 设置对象等待以下参数之一:

  • Map of data source properties, // See API reference for available options
  • URL to an OData service
  • JSON array

但是在您的代码中,分配给 dataSourceaProduct 是对 "A" 模型的引用,该模型 无效 .

应设置dataSource,根据模型类型,相应:

ODataModel

const odataListBinding = this.byId("myResponsiveTable").getBinding("items");
const serviceEntryPath = "/sap.app/dataSources/<em><sourceName></em>/uri"; // 请参阅 manifest.json 以获取 <sourceName>
const serviceUrl = this.getOwnerComponent().getManifestEntry(serviceEntryPath);
{ // Constructor settings of sap/ui/export/Spreadsheet
  dataSource: {
    type: "OData",
    useBatch: true,
    serviceUrl: serviceUrl,
    headers: odataListBinding.getModel().getHeaders(),
    dataUrl: odataListBinding.getDownloadUrl(), // serviceUrl + "/Orders" + added queries ($expand, $select, ...)
    count: odataListBinding.getLength(),
    sizeLimit: /*e.g.*/1000,
  },
  worker: true, // false if working with mock server or if CSP is enabled.
  fileName: "myExportedDataFromODataV2.xlsx"
}

注意:请确保dataUrl中包含相应的$expand参数。否则,将不会导出嵌套属性。

示例

使用客户端模型(例如 JSONModel

{ // Constructor settings of sap/ui/export/Spreadsheet
  dataSource: myJSONModel.getProperty("/SomeCollection"), // returns an array
  fileName: "myExportedDataFromPlainJSON.xlsx"
}
