Question to resolve initialize database in $stateProvider

ionic-v1
#1

Hi all,

I just learnt to use resolve in $stateProvider for nest state. My goal is to initialize database before the app loads the very first view because I have to get data from database to show in the slidebox.

I tried to put DB.init() in $ionicPlatform.ready(function() {}). But it just works to ionic serve. When I run on my android phone, it can not open database before load the homepage.

Then i found resolve method. I tried it like this:
the abstract state for slidemenu

.state('app', {
        abstract: true,
        url:"/app",
        templateUrl: "app/layout/menu-layout.html",
        resolve: {
          dbReady: function(DB){
            console.log("dbReady");
            return DB.init().then(function(){
              console.log("db is Ready");
            });
          }
        }
      })

state define for home page

.state('app.home', {
        url: "/home",
        views: {
          'mainContent': {
            templateUrl: "app/home/home.html",
            controller: 'HomeCtrl'
          }
        }
      })
.state('app.games',
.state('app.game-detail',
.state('app.scanner',
.state('app.setting'

It actually works for both browser and Android. But it also bring a lot of error codes like:

D/CordovaLog(14201): Watchers fired in the last 5 iterations: []

D/CordovaLog(14201): file:///android_asset/www/lib/ionic/js/ionic.bundle.js: Line 19387 : Error: [$rootScope:infdig] 10 $digest() iterations reached. Aborting!

“dbReady” and “initing db” is console.log for me to know where the app runs to.

I can get what I want in the app test but I am worry about the errors…

Appreciate for the help…
