Missing methods when migrating from odata v2 to v4

I'm trying to implement odata v4 for my current master detail app which was using odata v2.

In my app, I used some statements like these.

this.getOwnerComponent().getModel().metadataLoaded().then(fnSetAppNotBusy);

var oContext = this.getModel().createEntry(sPath, {
    properties: {
           Name: "ABC",
           Age: "20"
        },
    success: this._fnEntityCreated.bind(this),
        error: this._fnEntityCreationFailed.bind(this)
});

I see in this document Changes Compared to OData V2 Model, odata v4 has replaced metadataLoaded with "corresponding methods".

I have searched and found some but am not sure if these methods are correct. Can someone please confirm?

And I can't find method createEntry in oDataModel v4, so how can I implement the same logic as I did with odata v2?

Thanks

Solution

  • Hmm. The creation is covered in this example:

    https://sapui5.hana.ondemand.com/sdk/#/sample/sap.ui.core.tutorial.odatav4.06/code

    (Basically, you execute the creation on binding/context level)

    As for onMetadataLoaded, you may use getMetaModel() and then use the „appropriate” functions with promises, but I’d go as follows: grab your binding, which is the one you are waiting for, and attach to the event dataReceived. E.g.,

    oTable.getBinding('items').attachEvent('dataReceived', function(){...})

    The API docs explicitly states that this event is to be used for busy indicators:
