Get data from oData binding

[jakob_steen-petersen]

Hi

I need to read data from my default model (oData). I try this code

var oDataModel = this.getModel()
var test = oDataModel.getProperty("/PurchaseOrderSet");

But test is "undefined" - what do i do wrong?

Here is debug where you can se data is in there:

Hi

According to https://ui5.sap.com/#/topic/6c47b2b39db9404582994070ec3d57a2%23loioadd47c3966dd40489e952bb4f5f74a7c method getProperty does not trigger real data reading. Before call this method you should call read method as in https://ui5.sap.com/#/topic/6c47b2b39db9404582994070ec3d57a2#loioff667e12b8714f3595e68f3e7c0e7a14sec...

I don´t need to Read anything. Data is read and bound ok.... Check debugger screenshot

Then you are passing bad data path to getProperty. It shoud be like

oModel.getProperty("/Customer('ALFKI')/Address");<br>

In your code you only passed EntitySet identifier. No id of an entity, no property of an entity.

Hi Sergey

You are right - almost 🙂

The problem was that i need to include the key to the string:

oDataModel.getProperty("/PurchaseOrderSet('4500000999')/Field1");

Problem is then: what if the field i need actually is the key?

Hi

I don't see any problem. Key is a special property. It also has identifier. For example "/PurchaseOrderSet('4500000999')/KeyFieldId".

you can use this snippet to get the bound data for the whole table.
if you're using sap.m.Table, change the aggregation binding "rows" with "items". it should work also.

oTable.getBinding("rows").getAllCurrentContexts().map(row => { return row.getObject() } )

onInit: function () {
            var sUrl = "/northwind";
            var oModel = new sap.ui.model.odata.v2.ODataModel(sUrl);
            oModel.read("/PurchaseOrderSet", {
                success: function (data, response) {
                    console.log(data);
                },
                error: function (error) {
                    var errorCode = error.statusCode;
                    var status = error.statusText;
                    MessageBox.error(errorCode + ":" + status);
                }
            });
            this.getView().setModel(oModel);
        },

Hi Nadya

Thanks - but i must have been un-precise: case is that i already have read data from the backend. No problem there.

But i have a function where i need to use some data from the data fetched. Basically i need the value of some fields in the PurchaseOrderSet (like Purchase Order Number and other things) to use them for other things.
