Binding OData to XML view

[JBrook]

I have a simple requirement to get OData from the backend to populate the sap.m.select on my XML view. It works if I use a hard code json array in the app. or if I use a JS view but not with an XML view.

In my controller.js I have:

var sServiceUrl = "/sap/opu/odata/sap/ZRE_FACILITY_SRV/";
var oModel = new sap.ui.model.odata.ODataModel(sServiceUrl, true);

OData.request
({
requestUri: "/sap/opu/odata/sap/ZRE_FACILITY_SRV/BusEntitySet",
method: "GET",
headers:
{
"X-Requested-With": "XMLHttpRequest",
"Content-Type": "application/atom+xml",
"dataType" : "json",
"DataServiceVersion": "2.0"
}
},
function (oData, response) {

var oModel1 = new sap.ui.model.json.JSONModel();
oModel1.setSizeLimit(oData.results.length);
oModel1.setData(oData.results);
var oSelect = this.getView().byId("SelectID");
oSelect.setModel(oModel1, "appData1");


//oModel1.setProperty("/modelData", oData.results);
//var oSelect = this.getView().byId("SelectID");
//var oTemplate = new sap.ui.core.Item({key: "{Swenr}", text: "{Xwetext}" });
//oSelect.setModel(oModel1);
//oSelect.bindAggregation("items", "/modelData", oTemplate);

},
function (err) {alert("Error in getting Data");
} );

then in my view.xml I have

<Label text="Business entity" />
<Select id="SelectID" items="{ path: 'appData1>/BusEntitySet'}">
<core:Item key="{appData1>Swenr}" text="{appData1>Xwetext}" />
</Select>

Hi,

If you are using SAPUI5 and calling an odata service, you can use all the methos of the model.

var oModel = new sap.ui.model.odata.ODataModel(sServiceUrl, true);

The ODataModel, has a own method for reading, (Also, I strongly recommend you to use OData.v2), an example of a read request would be :

var oModel = new sap.ui.model.odata.v2.ODataModel(sServiceUrl, true);
oModel.read("/EntitySet",{
     success : function(oData){
     alert("Success");<br>     //...
     },

     error : function(oEvent){
     //....
     }
});

Try this 🙂

Hope it helps
