在Angular JS中注入控制器的问题

Question

我尝试为对话框定义一个控制器，如Angular Material示例中所示（here）

app/models/concerns/rent_readiness.rb

但我总是这样：

  

错误：[$ injector：unpr]未知提供程序：DialogControllerProvider＆lt; - DialogController＆lt; - MainController

您无法注入控制器。因此，从DialogController中的依赖项注入参数中删除MainController，并使用controller: 'DialogController'进行对话：

TestApp.controller('MainController', function MainController($scope, $mdDialog, $mdMedia) {

  // ...

  $scope.showImprintDialog = function(ev) {
    var useFullScreen = ($mdMedia('sm') || $mdMedia('xs')) && $scope.customFullscreen;
    $mdDialog.show({
        controller: 'DialogController',
        templateUrl: 'impressum.html',
        parent: angular.element(document.body),
        targetEvent: ev,
        clickOutsideToClose: true,
        fullscreen: useFullScreen
      })
      .then(function(answer) {
        $scope.status = 'You said the information was "' + answer + '".';
      }, function() {
        $scope.status = 'You cancelled the dialog.';
      });
    $scope.$watch(function() {
      return $mdMedia('xs') || $mdMedia('sm');
    }, function(wantsFullScreen) {
      $scope.customFullscreen = (wantsFullScreen === true);
    });
  };

  // ...

});
