Integrating services with a property editor

Overview

This is step 3 in the Property Editor tutorial. In this part, we will integrate one of the built-in Umbraco Services. For this sample, we will use the notificationsService to show a dialog with a custom view when you click in a textbox. The dialog will appear if the content is longer than 35 characters.

Injecting the service

First up, we need to get access to the service. This is done in the suggestion.controller.js, where we add it as a parameter:

Hooking into Textbox

To hook the service with the textbox, we will use the add method of the notificationsService. This will be used to render our own view by setting the view property. We will also pass an args object which contains the Property Value and a callback function that we are going to call from our notification.

The callback is used to return data to the editor.

Now that we have access to the editor events, we will trim the text to a length of 35.

Now let's edit the getSuggestion method to call showNotification on clicking Get Suggestions button.

At this point your controller should look like this:

Add the directive in the `suggestion.html`

Add the JavaScript file in `package.manifest`

Creating custom Notification View and Controller

We will add 2 files to the /App_Plugins/Suggestions/ folder:

notification.html
notification.controller.js

In the notification.html, we'll add:

In the notification.controller.js we will add:

Restart the application and either enter a suggestion longer than 35 characters or click on the Get Suggestions button. When you do so and click in the textarea, you will be presented with a notification like this:

The notification object contains the args object that we passed to the view in our suggestion.controller.js. When we click the Yes button in the notification, we use the callback function from the Suggestions controller. This function is executed in the scope of our Suggestions Property Editor.

Wrap up

Over the 3 previous steps, we have:

Created a plugin.
Defined an editor.
Registered the Data Type in Umbraco.
Added a $scope object to pass information from the controller to the view.
Added configuration to the Property Editor.
Connected the editor with the Notification Service.
Looked at the notification dialog in action.

Integrating services with a property editor

Overview

Injecting the service

First up, we need to get access to the service. This is done in the suggestion.controller.js, where we add it as a parameter:

Hooking into Textbox

The callback is used to return data to the editor.

Now that we have access to the editor events, we will trim the text to a length of 35.

   $scope.TrimText = function () {
        $scope.model.value = $scope.model.value.substring(0, 35);
    };

Now let's edit the getSuggestion method to call showNotification on clicking Get Suggestions button.

    $scope.getSuggestion = function () {
    
        // The getSuggestion method reads a random value from an array and provides a Suggestion. 
        $scope.model.value = $scope.aSuggestions[$scope.aSuggestions.length * Math.random() | 0];
        $scope.showNotification();
    }

At this point your controller should look like this:

angular.module("umbraco")
    .controller("SuggestionPluginController",
        // Scope object is the main object which is used to pass information from the controller to the view.
        function ($scope, notificationsService) {

            if ($scope.model.value === null || $scope.model.value === "") {
                $scope.model.value = $scope.model.config.defaultValue;
            }

            // SuggestionPluginController assigns the suggestions list to the aSuggestions property of the scope
            $scope.aSuggestions = ["You should take a break", "I suggest that you visit the Eiffel Tower", "How about starting a book club today or this week?", "Are you hungry?"];

            // The controller assigns the behavior to scope as defined by the getSuggestion method, which is invoked when the user clicks on the 'Give me Suggestions!' button.
            $scope.getSuggestion = function () {

                // The getSuggestion method reads a random value from an array and provides a Suggestion. 
                $scope.model.value = $scope.aSuggestions[$scope.aSuggestions.length * Math.random() | 0];
                $scope.showNotification();
            }
         
            // The controller assigns the behavior to scope as defined by the getState method, which is invoked when the user toggles the enable button in the data type settings.
            $scope.getState = function () {

                //If the data type is enabled in the Settings the 'Give me Suggestions!' button is enabled
                 if (Boolean(Number($scope.model.config.isEnabled))) {
                    return false;
                }
                return true;
            }

            //// function to show custom notification
            $scope.showNotification = function () {
                if ($scope.model.value.length > 35) {
                    notificationsService.add({
                        // the path of our custom notification view
                        view: "/App_Plugins/Suggestions/notification.html",
                        // arguments object we want to pass to our custom notification
                        args: {
                            value: $scope.model.value,
                            callback: $scope.TrimText
                        }
                    });
                }
            };

            // function to trim the text to a length of 35.
            $scope.TrimText = function () {
                $scope.model.value = $scope.model.value.substring(0, 35);
            };

        });

Add the directive in the `suggestion.html`

    <input type="text" ng-model="model.value" ng-click="showNotification()" />

Add the JavaScript file in `package.manifest`

{
 "javascript": [
        "/App_Plugins/Suggestions/suggestion.controller.js",
        "/App_Plugins/Suggestions/notification.controller.js"
    ]
}

Creating custom Notification View and Controller

We will add 2 files to the /App_Plugins/Suggestions/ folder:

notification.html
notification.controller.js

In the notification.html, we'll add:

<div ng-controller="NotificationController">
    <h4>Your Suggestion is too long.</h4>
    <p>Do you want to trim the text ?</p>
    <p>Trimmed text : {{trimmedtext}}</p>
    <button class="btn umb-alert--warning" ng-click="cancel(notification)">No</button>
    <button class="btn umb-alert--info" ng-click="trim(notification)">Yes</button>
</div>

In the notification.controller.js we will add:

angular.module('umbraco')
 .controller('NotificationController', function ($scope, notificationsService) {

      // the notification is set on scope by umbraco, so we can access our args object passed in
   $scope.trimmedtext = $scope.notification.args.value.substring(0, 35);

   $scope.trim = function (not) {
    // call our callback function set on the args object in our property editor controller
    not.args.callback();
    notificationsService.remove(not);
   };

   $scope.cancel = function (not) {
    notificationsService.remove(not);
   };
  });

Registered the Data Type in Umbraco.

            if ($scope.model.value === null || $scope.model.value === "") {
                $scope.model.value = $scope.model.config.defaultValue;
            }

            // SuggestionPluginController assigns the suggestions list to the aSuggestions property of the scope
            $scope.aSuggestions = ["You should take a break", "I suggest that you visit the Eiffel Tower", "How about starting a book club today or this week?", "Are you hungry?"];

            // The controller assigns the behavior to scope as defined by the getSuggestion method, which is invoked when the user clicks on the 'Give me Suggestions!' button.
            $scope.getSuggestion = function () {

                        args: {
                            value: $scope.model.value,
                            callback: $scope.TrimText
                        }
                    });
                }
            };

            // function to trim the text to a length of 35.
