过滤sapui5中的ODATA模型并与tilecontainer绑定

Question

我正在 xml 视图中绑定我的图块容器

    <TileContainer id="idsolutionContainer"     tiles="{ path: 'dlCourses>/DLES_COURSE_CONTENT' }">
       <tiles>
            <dles:DLESScoreTile name="{dlCourses>LJ_TITLE}" topicId="{dlesScore>ID}" topic="{dlCourses>LJ_SOLUTION}" dles="{dlCourses>DLES}" id="tileDLESCourse" press=".handleCourseClick"></dles:DLESScoreTile>
        </tiles>
    </TileContainer>`

并且在 inint 函数的后端，我试图通过 LJ_SOLUTION 进行过滤，但它不起作用。它给了我所有的课程。我从查询字符串中得到 LJ_SOLUTION，这就是我不在前端进行过滤的原因。代码为

        var coursePath = "/DLES_COURSE_CONTENT";
        var filterByName = new sap.ui.model.Filter('LJ_SOLUTION', 'EQ', 'Analytics')
        //sPath = "/DLES_SOLUTION_CONTENT?$filter=LJ_SOLUTION eq  '" + sId + "')";
        var courses = oView.getModel("dlCourses");
        var courseData = oModel.getData(coursePath);
        oView.bindElement({
            path: coursePath,
            filters: [ new sap.ui.model.Filter("LJ_SOLUTION",sap.ui.model.FilterOperator.EQ, "Analytics") ],
            model: "dlCourses",
            events: {
                dataRequested: function() {

                    oView.setBusy(true);
                },
                dataReceived: function() {
                    oView.setBusy(false);
                }
            }
        });

网络选项卡... 还有另一个我不完全理解的请求批次，但请求查询是

Answer 1

请删除代码“var courseData = oModel.getData(coursePath);”

因为这会加载整个模型。 bindElement 还将创建一个仅加载所需数据的请求。然后，检查由 bindElement 创建的请求以查看 “LJ_Solution” 的路径是否正确。

Answer 2

            var oView = this.getView();
var oSolutionJourneyList = oView.byId("idsolutionContainer");
            var oBinding = oSolutionJourneyList.getBinding("tiles");
            if (oBinding) {
                var oFilter = new sap.ui.model.Filter("LJ_SOLUTION", 'EQ', 'Analytics');
                oBinding.filter([oFilter]);
            }
