AngularJS - wait for multiple resource queries to complete

Question

I have a single factory defined with ngResource:

App.factory(\'Account\', function($resource) {
    return $resource(\'url\', {}, {
        query: { method:

You'll want to use promises and $q.all().

Basically, you can use it to wrap all of your $resource or $http calls because they return promises.

function doQuery(type) {
   var d = $q.defer();
   var result = Account.query({ type: type }, function() {
        d.resolve(result);
   });
   return d.promise;
}

$q.all([
   doQuery('billing'),
   doQuery('shipping')
]).then(function(data) {
   var billingAccounts = data[0];
   var shippingAccounts = data[1];

   //TODO: something...
});
