Loading OData without Table or List object in SAPUI5 - odata

Question

I have 2 weeks looking for an example to understand how the OData works.
I have defined in the Manifest.json my url with the OData service
{
"_version" : "1.7.0",
"sap.app" : {
"id" : "test",
"type" : "application",
"i18n" : "i18n/i18n.properties",
"applicationVersion": {
"version" : "1.0.0"
},
"title" : "{{appTitle}}",
"description" : "{{appDescription}}",
"sourceTemplate": {
"id" : "servicecatalog.connectivityComponent",
"version" : "0.0.0"
},
"dataSources" : {
"Test" : {
"uri" : "/sap/opu/odata/sap/ZMY_SERVICE_SRV/",
"type" : "OData",
"settings" : {
"odataVersion" : "2.0",
"localUri" : "localService/metadata.xml"
}
}
}
}..
"models": {
"i18n": {
"type": "sap.ui.model.resource.ResourceModel",
"settings": {
"bundleName": "test.i18n.i18n"
}
},
"Test": {
"type": "sap.ui.model.odata.v2.ODataModel",
"settings": {
"defaultOperationMode": "Server",
"defaultBindingMode": "TwoWay",
"defaultCountMode": "None"
},
"dataSource": "Test"
},
and in my Component.js within the Init method:
init: function() {
// call the base component's init function
UIComponent.prototype.init.apply(this, arguments);
// create the views based on the url/hash
this.getRouter().initialize();
// set the device model
this.setModel(models.createDeviceModel(), "device");
var sServiceUrl = this.getMetadata().getManifestEntry("sap.app").dataSources["Test"].uri;
var oModel = new sap.ui.model.odata.v2.ODataModel(sServiceUrl);
this.setModel(sabModel, "/Test");
sabModel.read(sServiceUrl, "Test");
}
I don´t want to use a Table or a List to load the OData from Backend. I want to load the information "manually" and based on what I got from the Backend, I want to navigate to one or another View.
Debugging the result in the navigator I see the following error: Console
Checking the Error Log I can see: Error Log
If I test the service in Backend works fine: OData Service
I got:

Thank you for your help!!! Any input is more than welcome!!

Answer 1

try this
var oModel = this.getModel("Test");//get the model
oModel.read("/TestSet", {
method: "GET",
success: function(data) {
alert(JSON.stringify(data));
},
error: function() {
}
});

Read the API documentation about "read" method:
https://sapui5.netweaver.ondemand.com/#/api/sap.ui.model.odata.v2.ODataModel
You should not specify the service URL in read method, because it automatically gets concatenated with "sPath", which you pass as a first argument. You should use the name of entityset (is defined in $metadata) you want to read starting with slash "/".
