在主 - 详细视图中,我有一个工作中心列表作为主要部分,计划日历作为详细部分。
<mvc:View controllerName="sap.ui.demo.wt.controller.Overview"

</List>
</semantic:MasterPage>
</masterPages>

我想根据员工所属的工作中心过滤计划日历。
这是控制器:
sap.ui.define([
"sap/ui/core/mvc/Controller",
"sap/ui/model/json/JSONModel",
"sap/ui/model/odata/v2/ODataModel",
"sap/ui/model/Filter",
"sap/ui/model/FilterOperator"
], function(Controller,JSONModel,ODataModel,Filter,FilterOperator) {
"use strict";
return Controller.extend("sap.ui.demo.wt.controller.Overview", {
onInit: function(){
this.getView().setModel(new JSONModel({
"StartDate" : new Date("2016-06-12T08:00:00Z")
}));
},
onWorkCtrPressed: function(oEvent) {
var oContext = oEvent.getSource().getBindingContext("data");
var sWorkCntr = oContext.getPath().split("'")[1]; //get the work center's name
//What I tried first
//var aFilter = [];
//aFilter.push(new Filter("WorkCntr",FilterOperator.StartsWith,sWorkCntr))
//this.getView().byId("PC").getBinding("rows").filter(aFilter);
sap.m.MessageToast.show("Selected Work Center : " + sWorkCntr);
}
});
});
我首先尝试的操作不起作用,因为查询在实体集"WorkCntr"
中查找属性"EmployeeSet"
。但是此属性仅存在于我在视图中展开的实体集"EmployeeWorkCenterSet"
中。问题是:我甚至不知道我需要使用的查询......你能帮忙吗?
PS:我的OData服务是版本2.查询类似
EmployeeSet?$expand=EmployeeWorkCenter($filter={any filter})
不起作用。
答案 0 :(得分:0)
如上所述in this answer,您可以将导航属性名称添加到Filter路径,如下所示:
new Filter({
path: "EmployeeWorkCenter/WorkCntr", // "EmployeeWorkCenter" === navigation property from Employee
operator: FilterOperator.StartsWith,
value1: sWorkCntr
});
(我假设解析导航属性EmployeeWorkCenter
会返回一个对象而不是另一个集合。否则,这将无法在V2中工作)
