Hello, I’m trying to configure switching of a CategoryPage that is connected to the Realtime Database, I can only do it in one direction, I think I need to update the JsonListModel??? If so, please tell me how to do it correctly.
import QtQuick.Controls
import QtQuick.Layouts
import QtQuick
import Felgo
App {
property var shoppingItems: ({})
property string dbKeyAllShoppingItems : “showcase”
//create a model for a category
function createModelForCategory(category)
{
dbKeyAllShoppingItems = category
database.getValue(category)
}
// ————————————————————————————-
// configuration FireBase
FirebaseConfig {
id: fbConfig
}
FirebaseDatabase {
id: database
config: fbConfig
realtimeValueKeys: [dbKeyAllShoppingItems]
onRealtimeValueChanged: (success, key, value) => {
if(success && key === dbKeyAllShoppingItems) {
shoppingItemsLoaded(value)
}
}
onReadCompleted:(success, key, value) => {
if(success && key === dbKeyAllShoppingItems) {
shoppingItemsLoaded(value)
}
}
}
// Function that updates the internal data store whenever the values
// changes in the Firebase database in real time.
function shoppingItemsLoaded(value) {
shoppingItems = value || {}
}
JsonListModel {
id: jsonModel
// readonly property var shoppingItem: dataModel.shoppingItems[modelData] || {}
source: shoppingItems || {} //[modelData] || {}//Object(dataModelfareBase.shoppingItems)//(dataModelfareBase.shoppingItems)
// keyField: “id”//dataModel.shoppingItems[modelData] || {}
//Defines the available model fields. If not installed,
//JsonListModel will use the first added entry as a reference.
fields: [“title”,”text”,”name”]
}
Navigation {
id: appNav
navigationMode: navigationModeTabs
anchors.fill: parent
NavigationItem {
title: qsTr(“showcase”)
iconType: IconType.thlarge
NavigationStack {
id: navStack0
CategoryPage {category: “showcase”}
}
}
NavigationItem {
title: qsTr(“catalog”)
iconType: IconType.alignjustify//ellipsish
NavigationStack {
id: navStack4
CategoryPage {category: “catalog”}
}
}
}
import QtQuick
import Felgo
import QtQuick.Controls
AppPage {
title: category
property var category
Component.onCompleted: {
createModelForCategory(category)
}
AppListView {

anchors.fill: parent

}
