angular material load angularjs 1.5 component into $mdDialog

问题

The goal: to use components and not use $scope to set data. There isn't an error to share, the issue is that the data element isn't set when the dialog loads the component. The screen shot shows the current state of the dialog, there should be an object bound in tab #2 (Info). I can verify the the object (document) is available after the dialog loads using the onComplete event. I've tried to bind the data available to the dialog call to the component in the following ways below:

1 using locals:

  locals: {
         document: document     
  },
  bindToController: true,
  onComplete: function(){
                    console.log('document: %O', document);
  }

2 using bindings:

   bindings: {
         document: '='
    }

3 using resolve:

  resolve: {
              document: function() {
                          return document;
                        }
            }

The component:

I believe the error is here, the bindings, the "old way" used $scope vars so the bindings wired effortlessly.

(function(){
'use strict';
angular.module('adminClientApp')
.component('documentEdit', {
    templateUrl: 'js/app/components/document/documentEdit/document-edit.html',
    controller: function DocumentEditController($mdToast, $mdMedia) {
       var var documentEdit = this;
        documentEdit.document;

       },
       bindings: {
         document: '<'
       }
    });
  })();

the dialog call

the DialogController just has the $mdDialog events in it. I realize that the locals and bindToController are targeting the controller specified in the dialog (DialogController). I'm stumped here - how to set/pass/wire the document to the component controller?

   this.showEdit = function ($event, document) {
                var parentEl = angular.element(document.body);

                $mdDialog.show({
                            parent: parentEl,
                            targetEvent: $event,
                            template: '<div><document-edit document="documentEdit.document"></document-edit></div>',
                            resolve: {
                                       document: function(){ return document;}
                            },
                            controller: DialogController,
                            onComplete: function(){
                                console.log('document: %O', document);
                            }
                        });

        }

You don't show your DialogController, but there is probably an issue in there. I believe that you also need to give it a string when you give it a controller reference, e.g.

controller: 'DialogController',

See the below example which shows how to pass in values correctly using $mdDialog.

(function() {
  angular
    .module('exampleApp', ['ngAnimate', 'ngAria', 'ngMaterial'])
    .controller('ExampleController', ExampleController);

  function ExampleController($mdDialog) {
    var vm = this;
    vm.dialogTemplate = '<md-dialog><md-dialog-content><document-edit document="vm.document"></document-edit></md-dialog-content></md-dialog>';
    vm.document = {
      id: '11',
      name: 'test',
    };
    vm.showLocalsBindedDialog = function(event) {
      $mdDialog.show({
        template: vm.dialogTemplate,
        targetEvent: event,
        clickOutsideToClose: true,
        escapeToClose: true,
        controller: 'DocumentDialogCtrl',
        controllerAs: 'vm',
        bindToController: true,
        locals: {
          'document': vm.document
        }
      });
    }

    vm.showResolveBindedDialog = function(event) {
      $mdDialog.show({
        template: vm.dialogTemplate,
        targetEvent: event,
        clickOutsideToClose: true,
        escapeToClose: true,
        controller: 'DocumentDialogCtrl',
        controllerAs: 'vm',
        bindToController: true,
        resolve: {
          document: function() {
            return vm.document;
          }
        }
      });
    }
  }
  ExampleController.$inject = ['$mdDialog'];
})();

(function() {
  angular
    .module('exampleApp')
    .controller('DocumentDialogCtrl', DocumentDialogCtrl);

  function DocumentDialogCtrl(document) {
    var vm = this;
    vm.document = document;
  }
  DocumentDialogCtrl.$inject = ['document'];
})();

(function() {
  'use strict';
  angular.module('exampleApp')
    .component('documentEdit', {
      bindings: {
        document: '<'
      },
      template: '<p>ID:{{vm.document.id}}</p><p>NAME:{{vm.document.name}}</p>',
      controller: DocumentEditController,
      controllerAs: 'vm'
    });

  function DocumentEditController() {
    var vm = this;
  }
})();

Another possibility is the is to use the scope option.

const tempScope = $rootScope.$new(true);
tempScope.document = document; // This is the local variable

$mdDialog.show({
    scope: tempScope // Give the scope to the dialog
    parent: parentEl,
    targetEvent: $event,
    template: '<document-edit document="document"></document-edit>', // Use scope
    onComplete: function() {
        console.log('document: %O', document);
    }
});

This will create a temporary scope for compiling the template. You still need to bind the data in the template (document="document"), but you can omit the intermediate controller.

Note that if you want to use the resolve to resolve promises, you need to do that manually before showing the dialog.
