我使用" TwoWay"将ODataModel与表绑定在一起。捆绑。我需要允许用户编辑表格的行,我已经在其中保存了'保存'按钮。目前虽然该表是可编辑的,但我无法编辑表格多行中的条目 请在下面找到我的代码:
var oTable = new sap.ui.table.Table("dprTable",{
visibleRowCount: 4,
visible: true,
navigationMode: sap.ui.table.NavigationMode.Paginator
});
var oColumn = new sap.ui.table.Column({
label: new sap.ui.commons.Label({text: "DBR/DPR"}),
template: new sap.m.Link({
"target": "_blank",
press:[controller.onClickDemoNo,controller]
}).bindProperty("text","DemoId"),
width: "auto",
tooltip: "DBR/DPR"
});
oTable.addColumn(oColumn);
oTable.addColumn(new sap.ui.table.Column({
label: new sap.ui.commons.Label({text: "Description"}),
template: new sap.ui.commons.TextView().bindProperty("text", "DemoDesc"),
width: "auto",
tooltip: "Description"
}));
oTable.addColumn(new sap.ui.table.Column({
label: new sap.ui.commons.Label({text: "Required Date"}),
template: new sap.ui.commons.DatePicker("",{
value:{
path:"ReqDate",
type: new sap.ui.model.type.Date({pattern: "dd-MM-yyyy"})
},
change: function(){
console.log('the date is changed and it\'s value is'+value);
},
}),
width: "auto",
tooltip: "Required Date"
}));
oTable.addColumn(new sap.ui.table.Column({
label: new sap.ui.commons.Label({text: "Requestor"}),
template: new sap.ui.commons.TextView().bindProperty("text", "RequestorName"),
width: "auto",
tooltip: "Requestor"
}));
oTable.addColumn(new sap.ui.table.Column({
label: new sap.ui.commons.Label({text: "Requestor/Project Lead"}),
template: new sap.ui.commons.TextView().bindProperty("text", "LeadName"),
width: "auto",
tooltip: "Requestor/Project Lead"
}));
oTable.addColumn(new sap.ui.table.Column({
label: new sap.ui.commons.Label({text: "Solution"}),
template: new sap.ui.commons.TextView().bindProperty("text", "SolutionText"),
width: "auto",
tooltip: "Solution"
}));
oTable.addColumn(new sap.ui.table.Column({
label: new sap.ui.commons.Label({text: "Start Date"}),
template: new sap.ui.commons.DatePicker("",{
value:{
path:"StartDate",
type: new sap.ui.model.type.Date({pattern: "dd-MM-yyyy"})
}
}),
width: "auto",
tooltip: "Start Date"
}));
oTable.addColumn(new sap.ui.table.Column({
label: new sap.ui.commons.Label({text: "End Date"}),
template: new sap.ui.commons.DatePicker("",{
value:{
path:"StartDate",
type: new sap.ui.model.type.Date({pattern: "dd-MM-yyyy"})
}
}),
width: "auto",
tooltip: "End Date"
}));
oTable.addColumn(new sap.ui.table.Column({
label: new sap.ui.commons.Label({text: "Estimated Duration"}),
template: new sap.ui.commons.TextView().bindProperty("text", "EstDuration"),
width: "auto",
tooltip: "Estimated Duration"
}));
oTable.addColumn(new sap.ui.table.Column({
label: new sap.ui.commons.Label({text: "Hours"}),
template: new sap.m.Input("",{}).bindProperty("value", "ActDuration"),
width: "auto",
tooltip: "Hours"
}));
oTable.addColumn(new sap.ui.table.Column({
label: new sap.ui.commons.Label({text: "Status"}),
template: new sap.ui.commons.ComboBox({items: [
new sap.ui.core.ListItem({text: "New",key:"1"}),
new sap.ui.core.ListItem({text: "In Process",key:"2"}),
new sap.ui.core.ListItem({text: "Completed",key:"3"})
]}).bindProperty("value","StatusText"),
width: "auto",
tooltip: "Status"
}));
oTable.setBusyIndicatorDelay(1);
//oData service call
var oModel = new sap.ui.model.odata.ODataModel("/sap/opu/odata/sap/ZSECENTRAL_SRV",true);
oModel.setDefaultBindingMode("TwoWay");
oModel.attachRequestSent(function (oEvent) {
console.log('request sent');
oTable.setBusy(true);
});
oModel.attachRequestCompleted(function () {
console.log('request completed');
oTable.setBusy(false);
});
oModel.attachRequestFailed(function () {
oTable.setBusy(false);
});
oTable.setModel(oModel);
oTable.bindRows("/DEOPENDBRSet");
设置中是否有待处理的内容?要更新表中的多个记录,我是否必须使用一些批处理操作?任何帮助将不胜感激。

对于OData,除非使用批处理,否则一个http请求只能包含一个CRUD操作。因此,对于多个记录更新,建议使用批处理

我有同样的问题,我仍在寻找解决方案。 您的原始问题将在此处解释:http://scn.sap.com/thread/3372437
我还在搜索的是,如何通过一个模型的多个更改(在不同的对象/实体中)发出“一个”批处理请求?
我希望有类似的东西: oModel.applyChangesAsBatch();
现有元素的所有更改都使用绑定控件完成。 如果是新创建的实体,当然必须再次调用在模型上创建它。
换句话说:有没有办法使用普通绑定模型并告诉模型将一个请求(可能是批处理)中的所有更改发送到服务器,以便服务器能够存储“全部”或“没有” “?
