SAPUI5 - oModel.create 不是 function

Question

I'm trying to build a simple SAPUI5 application that basically lists a table filled with employee data (ID, name, address).

However, I cannot add new employee because I always get the same error:

Uncaught TypeError: oModel.create is not a function at constructor.Save (EmpDetails.controller.js?eval:87)

Could you please help me solve this? I don't understand why the create function does not work given that it is connected to the model and should work fine (just like the GET-method that fills the table on initialization). Here is my code for the controller:

 sap.ui.controller("zemployee_crud.EmpDetails", { onInit: function() { var sServiceUrl = "proxy/http/<server>:<port>/sap/opu/odata/sap/ZEMPLOYEE_SRV"; var oModel = new sap.ui.model.odata.ODataModel(sServiceUrl, true); var oJsonModel = new sap.ui.model.json.JSONModel(); oModel.read("/EmployeeSet",null,null,true,function(oData,response){ oJsonModel.setData(oData); }); sap.ui.getCore().setModel(oJsonModel); }, Save: function() { var oId = sap.ui.getCore().byId("Id").getValue(); var oName = sap.ui.getCore().byId("Name").getValue(); var oAddress = sap.ui.getCore().byId("Address").getValue(); var oEntry = {}; oEntry.Empid = oId; oEntry.Empname = oName; oEntry.Empadd = oAddress; var oModel = sap.ui.getCore().getModel(); oModel.create("/EmployeeSet", oEntry, null, function (response) { // success message // table reload }, function (Error) { //show error }); } });

Your JSONModel does not support create . You have to use an ODataModel.

First you have to store your model somewhere

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

Then later you can access the model and call create.

var oModel = this.getView().getModel();
oModel.create(...);

This is the most simple approach. I strongly suggest getting to know the framework:

• sap.ui.model.odata.ODataModel is deprecated. Use sap.ui.model.odata.v2.ODataModel .
• Declare your model in your manifest.json. Then all controllers can access it.
• In most cases you don't need an extra JSONModel. You can directly use the ODataModel and show it in your list
• Setting any model (JSON or OData) to the core ( sap.ui.getCore().setModel() ) is not necessary. The core is on a very high/global level. Mostly it's enough to set it on an app/component level (either in your manifest.json or in the Component.js) or on a controller level.

I also strongly suggest doing the official walkthrough . It takes 1-2 days to complete but after that you are almost a pro since it answers 95% of all beginner questions.
