How to change the oData version in webide

Question

I need to change my webide oData version to v1. The apps are created with v2 version automatically.I already have backend for my app according to batch operations based on v1.so I need to use that backend for my app.Is there any way to achieve this?

Answer 1

You should be able to specify the type in your manifest.json directly and can point to ODataModel v1

"models": {
    "": {
        "type":"sap.ui.model.odata.ODataModel",
        "dataSource":"mainService"
    }
},

Answer 2

I suspect you will not be able to change this with the new Freestyle Template and the manifest approach. In fact the code in the API instantiation is as follows

if (!j.type) {
    switch (k.type) {
    case 'OData':
        j.type = 'sap.ui.model.odata.v2.ODataModel';
        break;
    case 'JSON':
        j.type = 'sap.ui.model.json.JSONModel';
        break;
    case 'XML':
        j.type = 'sap.ui.model.xml.XMLModel';
        break;
    default:
    }
}

So as per the official documentation sap.ui.model.odata.ODataModel is deprecated.

However if your concern is only the batch processing, you can turn it off by this configuration in manifest file

"": {
    "dataSource": "mainService",
    "settings": {
        "metadataUrlParams": {
            "sap-documentation": "heading"
        },
     "useBatch": false,     
    }
}
