How to update a model in an existing data source?

[Jonathan]

How do I update a piece of data in an existing dataset? The following is the code I have for updating and adding to an existing dataset, the add works correctly, but how do I make the update work?

function AddEntityToDataSource(entityset, entity) {

 

    var ds = GetDataSource(entityset);

 

    ds.add(entity);   

     

}

 

function UpdateEntityToDataSource(entityset, entity) {

 

    var ds = GetDataSource(entityset);

 

    entity = ds.get(entity.id);

 

}

Hi Jonathan,

In order to modify field values of a Model instance you should use its set method:

entity = ds.get(entity.id);
entity.set("foo", "bar"); // set foo field value to be bar

Thanks Rosen, nice piece of information.

Is there a way I can replace the entire entity?

Hi Jonathan,

I'm afraid this is not supported.

All the best,
