How to disable V2 OData $batch request by default in UI5?

Question

I made a Master-Detail application in Web IDE with SAPUI5.

I connected my application to an OData service (V2). The connection parameters have been stored in manifest.json.

I want to prevent my UI5 application from using $batch requests.

I know how to use the following code to disable batch request for a particular request:

var oDataModel = this.getModel(); // sap.ui.model.odata.v2.ODataModel
oDataModel.setUseBatch(false);

But the problem is that I can not use this in onInit function.

Can I set some parameter in manifest.json to disable batch request in general and even when the program is loading it does not use $batch?

You should be able to add parameter useBatch to the settings of your model. According to the documentation (section /sap.ui5/models) these settings will be passed to the constructor.

{
  "sap.ui5": {
    "models": {
      "yourV2ODataModel": {
        "dataSource": "yourDataSource",
        "settings": {
          "useBatch": false
        }
      }
    }
  }
}

The availability of component models in onInit has been discussed here several times. See the application init process to see why they are not available.

Well you could to it in the onInit function. But like this:

var oDataModel = this.getOwnerComponent().getModel();

oDataModel.setUseBatch(false);

hi, setting properties of a model that is defined in manifest.json is not considered good idea. imagine the model being replaced by a mockservers model or what not. the correct answer is already given, and is to set the models settings in the manifest.json – Michael Schönbauer Jan 05 '21 at 16:27

Go to Component.js

on its "init" method:

this.getModel("yourDesiredModel").setUseBatch(false)
