OData read, create, update, delete - callback success and error functions

[Former Member]

Hi,

I use read/create/update/delete methods. These methods work fine because I pass in SAP debugger and all data are correctly read/created/updated/deleted in SAP from my UI5 interface values, but success and error callback functions aren't called.

Here is an example from my development :

     oKunnrSet= this.oComponent.getModel();

     oKunnrSet.read("/KunnrSet('USER')", null, null, true,

                                   function(oData, oResponse){

                                                    alert("Read successful");

                                },function(){

                                     alert("Read failed");});

If I execute my request in SAP NetWeaver Gateway, status_code = 200.

Have you an idea why success or error function are never called ?

I worked on SAPUI5 Version 1.26.9

try that:

oKunnrSet.read("/KunnrSet('USER')", {

     async : false,

     success : function(oData, response) {

          console.log("Read successfull");

     },

     error : function(oError) {

          console.log("Read failed");

     });

Thank you, your solution worked

You're welcome. If you take a look at the read method you'll see, that it takes only two parameters and the second one is a map.

I have always the same problem for CREATE, UPDATE and DELETE... I try to implement the same solution that READ, but success and error function doesn't called.

Can you give me an example for create, update and delete with success and error function callback ?

Read and remove are very similar, but the create and the update request also need the data you want to store as a parameter:

create(sPath, oData, mParameters?)

update(sPath, oData, mParameters?)

example:

oModel.create("BHEintragSet", {
       "Bpartner" : oData.Bpartner, 
       "Kjahr" :oData.Kjahr,
       "Hjahr" : oData.Hjahr,
       "Xdel" : ""
  }, {
       async : false,
       success : function(oData, response) {
            iSuccess++;
            sSuccessMessage += oView.getModel("i18n").getProperty("NewEntry") + ": " + oData.Kjahr + " " + oData.Hjahr + "\r\n";
       },
       error : function(oError) {
            iFail++;
            var oResponseBody = JSON.parse(oError.response.body);
            oView.getController().createMessageItem("Error", sSaveFailure,oData.Kjahr + ((oData.Hjahr)? " - " + oData.Hjahr : "") +  " : " + oResponseBody.err          or          .message.value);
  }
  });
  }

           var oBindingInfo = {

                filters : aFilters,

                success : function (oData) {

                    jQuery.sap.log.info("Odata Read Successfully:::");

                }.bind(this),

                error: function (oError) {

                    jQuery.sap.log.info("Odata Error occured");

                }.bind(this)

            };

            if (oModel) {

                oModel.read(sPath, oBindingInfo);

            }

I hope this might help you.

Thanks.

Please provide your network and console after you called read().

[santhu_gowdaz]

try,

oKunnrSet.read("/KunnrSet('USER')", null, null, false,

                                   function(oData, oResponse){

                                                    alert("Read successful");

                                },function(err){

                                     alert("Read failed");});
