Passing data to mdDialog

Question

Main listing page has edit button. Which opens details of the edited row.
Way-1: Now, if I set "ctrl.parent.q_details.client_location" it is bind with parent listing controller and it works as 2-way binding and automatically changes the values as in the edit box changes, Which is not requirement here.
Here just I want to display and allow edit values in inputbox. Not want to get changed in parent controller.

► Following is the code in parent controller to call mdDialog

$mdDialog.show({                 locals:{parent: $scope},                                 clickOutsideToClose: true,                                 controllerAs: 'ctrl',                                 templateUrl: 'quotation/edit/',//+edit_id,                 controller: function () { this.parent = $scope; },             }); 

► Following is code of the popup mdDialog.

<md-dialog aria-label="">     <div ng-app="inputBasicDemo" ng-controller="deliverController" layout="column">         <form name="" class="internal_note_cont">                        <md-content class="md-padding">                              <md-input-container class="md-input-has-value" flex>                     <label>Client Name</label>                     <input ng-model="qe.client_name" required >                 </md-input-container>                 <md-input-container flex>                     <label>Client Location</label>                     <input required ng-model="ctrl.parent.q_details.client_location">                 </md-input-container>                                </md-content>         </form>         <div>                    </div>     </div>     <input type="" required ng-model="ctrl.parent.q_details.recid">   </md-dialog> 

Way2: second way is sending the value directly from DB without binding to ng-model of Dialog controller(deliverController).

]).controller("deliverController", ["$scope", "$filter","$http","$route","$window","$mdDialog",     function ($scope, $filter,$http,$route,$window,$mdDialog) {         $scope.qe.client_name = '12345'; // just to test.             } 

This is giving error of undefine $scope.qe .

So ultimately, I am not able to send data to mdDialogue and display them and allow edit them as normal way. Please anyone experienced angular guy help me. I am new to angular. I am trying different ways since 2 days.

This guy always has the right answer: https://github.com/angular/material/issues/455#issuecomment-59889129

In short:

$mdDialog.show({             locals:{dataToPass: $scope.parentScopeData},                             clickOutsideToClose: true,                             controllerAs: 'ctrl',                             templateUrl: 'quotation/edit/',//+edit_id,             controller: mdDialogCtrl,         });  var mdDialogCtrl = function ($scope, dataToPass) {      $scope.mdDialogData = dataToPass   } 

Pass the variable using the locals attribute in the passing object. These values will be injected into the controller not the $scope. Also passing the entire $scope of the parent might not be such a good idea as it defeats the isolated scope paradigm.
