Transport->Read->Data Parameter

[sitefinitysteve]

I'd like my "data" to be sending some of my MVVM model properties in the callback...

Example:

transport: {
            read: {
                url: "/RestApi/directory?format=json",
                dataType: "json",
                data: {
                    search: $model.get("searchterm")
                }
            }
        },

So I have a searchbox which is bound to $dataSource.read(); ...but regardless of the method I'm using (sync, fetch, read) that "data" never seems to be re-called.  Well...I mean I can't say that it's not working, maybe it is, and it's returning "", although I've valdiated my model has data in "searchterm"

Thoughts?

Hello Steve,

You can easily check the value of searchterm by using a function, for example: 

transport: {
    read: {
        url: "/RestApi/directory?format=json",
        dataType: "json",
        data: function(){
            console.log($model.get("searchterm"));
            return {
                search: $model.get("searchterm")
            };
        }
    }
},

You can also pass the additional data by calling the DataSource's read method: 

$dataSource.read({search: $model.searchitem})
