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:

The solution from Ben Lesh is the best but it's not complete. If you need to handle error conditions--and, yes, you do--then you must use the catch method on the promise API like this:

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

   //TODO: something...

}).catch(function(data) {

   //TODO: handle the error conditions...

}).finally(function () {

  //TODO: do final clean up work, etc...

});

If you don't define catch and all of your promises fail, then the then method won't ever execute and thus will probably leave your interface in a bad state.
