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.
