问题 Forgive if this is general, but I'm looking for an approach and I'm new to Angular. Say I have a main controller and a runtime created modal controller.

But the problem is that these are

问题 I followed the instructions on docs.angularjs.org to test a controller with karma and it's perfectly working. However I was wondering if it's possible to test a controller which is not using $scope? Testing this controller is ok: angular.module('starter.controllers') .controller('PasswordController', function PasswordController($scope) { $scope.password = ''; $scope.grade = function() { var size = $scope.password.length; if (size > 8) { $scope.strength = 'strong'; } else if (size > 3) {

问题 I have a User model that has billing_id. I have Order model that runs transactions with a payment gateway which returns a billing id I'd like to save into the billing_id column on the User model. I think I am getting the basics of MVC architecture mixed up. I am under the impression that UsersController and OrdersController update data of their respective tables.
