CRUD service - delete

var deleteCell = {
	name : "alfresco/documentlibrary/views/layouts/Cell",
	config : {
		widgets : [ {
			name : "alfresco/renderers/PublishAction",
			config : {
				iconClass : "delete-16",
				propertyToRender : "title",
				altText : "Delete {0}",
				publishTopic : "ALF_CRUD_DELETE",
				publishPayloadType : "PROCESS",
				publishPayload : {
					requiresConfirmation : true,
					url : "slingshot/datalists/list/node/{nodeRef}",
					confirmationTitle : "Delete Data List",
					confirmationPrompt : "Are you sure you want to delete '{title}'?",
					successMessage : "Successfully deleted '{title}'"
				},
				publishPayloadModifiers : [ "processCurrentItemTokens",
						"convertNodeRefToUrl" ]
			}
		} ]
	}
};

var viewRow = widgetUtils.findObject(model.jsonModel.widgets, "id", "VIEW_ROW");
viewRow.config.widgets.push(deleteCell);                        
                    

Looking at the configuration, the code will publish on the ALF_CRUD_DELETE topic to which the SkyVault/service/CrudService subscribes. It is also necessary to identify the specific item to be deleted.

When defining a publication payload you can optionally select a number of different payload types and in this case the publishPayloadType attribute is being set to PROCESS. This indicates that we want to perform some processing on the payload.

A number of processors have been included in Aikau and two are specified in the publishPayloadModifiers array:

• processCurrentItemTokens - looks for all string data wrapped in braces. For example, {nodeRef} in the string slingshot/datalists/list/node/{nodeRef}, is converted into the matching entry in the currentItem.
• convertNodeRefToUrl - replaces any occurrence of "://" with "/" to make NodeRef data URL friendly.

The CrudService recognizes that DELETE actions may require a confirmation, so the requiresConfirmation attribute is included in the payload, as well as the messages to use on the confirmation dialog title, confirmation dialog body, and the subsequent success message. Note that currentItem can be included in the message strings because it is always included in the publication to the service.

In the final part of the configuration the icon to use is specfified via the iconClass attribute, and the altText for the icon is also specified. The propertyToRender attribute is available for use as a message token in the alt text, so a meaningful text can be provided for the action.

You will see you are able to delete a data list. On deletion you will be prompted with a confirmation dialog box.
