Pass an Array in ListModel

Bernard Rouhi

I'm wondering how can I pass an array in ListModel?

ok, In QML I have a ListView and I set it's ListModel like so:

model: ListModel
{
    id: myList   
    ListElement 
    {
        name: ""
        card: 0
        books: []
    }

}

I can append to it by using:

myList.append({name:"terry", card:00100, books:["024589","865976","879582","215645"]});

but when I try to output it on screen I get this.

{
    "card": 00100
    "books": {
        "objectName": "",
        "count": 4,
        "dynamicRoles": false
     },
    "name": "terry",
    "name": "terry"
}

I'm not sure why I'm getting 2 names though! and how can I get the value of books?

I look up the QML documentation of ListModel and ListElement couldn't find anything related to passing an array, all the examples are integer or string.

Any idea how I can get the books date?
I did work around it by calling the array in Delegate with Component.onCompleted:{} but I believe that's not a good/correct way since Delegate is not responsible for holding the data and should be done in Model, please do correct me if I'm wrong.

Thanks for your time.

Edit01: here is the reason I need array:
I have a ComboBox in Delegate like so:

delegate: Rectangle
    {
     id: rowID
     width: 50
     height: 40
     color: "#323232"
     Row
     {
         anchors.fill: parent
         anchors.leftMargin: 10
         anchors.rightMargin: 10
         Label{
             id: nameID
             text: name
             font.pixelSize: 12
             width: 200
             wrapMode: Text.WrapAnywhere
             anchors.verticalCenter: parent.verticalCenter
             color: "#999"
         }

         Label{
             anchors.verticalCenter: parent.verticalCenter
             text: "out:"
             font.pixelSize: 12
             color: "#999"
         }

         ComboBox{
             id: booksID
             height: 20
             width: 50
             model: books
             anchors.verticalCenter: parent.verticalCenter
         }
     }
}

as you can see I'm feeding the name to Label (id: nameID) and I want to feed the books to ComboBox (id: booksID) that has model.

in QML ListModel or ListElement documentation didn't mention anything about getting all the key's value otherwise I would have used the ListElement, it only supports get(int index) which is based on an index number and I believe If I try to use Component.onCompleted:{} on ComboBox, it would slow down the performance. any suggestion?
