Question

我正在尝试使用time元素（类型为Edm.Time）实现可编辑的表元素。当更改表中的值并且应用程序发送PUT请求时出现问题。

时间对象的值例如是“PT11H00M00S”并且我已经通过元数据分配了类型“Edm.Time”以避免“Edm.string”比较问题。但现在oData服务是SAP显示如下。如何格式化值以避免此问题？提前谢谢

看起来像是提供给模型调用的上下文的__metadata属性中的问题。

              var obj = oSelectedItem.getBindingContext().getObject();
              var context = oEvent.getSource().getBindingContext().getObject();

              context.ldate    = obj.ldate;
              context.ltime    = obj.ltime;

              oController.onRowUpdate("/modelData(pdsnr='"+context.pdsnr+"')", 
                                      {ldate:    obj.ldate,
                                       ltime:    obj.ltime,
                                      });

现在它可以作为

SELECT *, SUM(DS.UnitPrice*Ord.Qty) as LineTotal ,SUM(LineTotal) as SubTotal,SUM(SubTotal*1.1) as TotalPrice
FROM (Orders Ord, Donuts DS, Customers Cust)
LEFT JOIN Customers ON (Cust.CustID = Ord.OrderID)
LEFT JOIN Donuts ON (DS.DonutID = Ord.DonutID)

使用Edm.Time类型的oData模型的PUT方法
