Notification for deleted document

Alice_

Hi, I'm a new user of Nuxeo. I'm wondering if it is possible to have notifications when a document is deleted. I write my extension point:

<component name="org.nuxeo.sample.notify">
    <extension point="notifications" target="org.nuxeo.ecm.platform.ec.notification.service.NotificationService">
        <notification autoSubscribed="false" availableIn="all" label="Delete" channel="email" enabled="true" name="Document Removed">
        <event name="documentRemoved" />
        </notification>
    </extension>
</component>

I can subscribe an user to receive the Delete notifications, but they don't work: when I delete a document, user does not receive the notification.

What's wrong?

Thank you very much, and sorry for my bad English!

There is no simply way to do that.

A solution would be to implement your own event 'documentDeleted' and to create a listener or by overriding the concerned bean to fired this event. See http://doc.nuxeo.com/display/NXDOC/Events+and+Listeners.

Is it normal that you have spaces in your target?

Alice_

I think that is a problem of formattation in the previous message...in orginal code there were not those spaces!

Clément_Lardeur

You need to precise a template for your notification :

<notification template="documentRemoved" autoSubscribed="false" availableIn="all" label="Delete" channel="email" enabled="true" name="Document Removed">
    <event name="documentRemoved" />
</notification>

Moreover the template must be defined in an other contribution point :

  <extension target="org.nuxeo.ecm.platform.ec.notification.service.NotificationService"
    point="templates">
    <template name="documentRemoved" src="templates/documentRemoved.ftl" />
  </extension>

You can see the template 'modif.ftl' to create your own template 'documentRemoved.ftl'.

I think it should work better!

Benjamin_Jalon1

Can you (by convention) use a name without space (this is the technical name, so my advice would be to use the Camel Case.

Have you defined your component into the Manifest ?

How did you generate your bundle. My piece of advice would be to use the Nuxeo IDE.

Or more easily you can use studio and copy you contribution (from <extension... to </extension>) into Advanced setting > XML Extension.

Regards.

The curious thing is that the code works with every other defined event (for example: documentModified or documentLocked or versionRemoved)... it doesn't work only with documentRemoved and I really don't understand why... (I try to add my own template...it works with other event too)

Alice_

This is my new piece of code: this works with every event, except for documentRemoved and documentMoved...can anyone tell me why?

<extension target="org.nuxeo.ecm.platform.ec.notification.service.NotificationService" point="templates">
    	<template name="remove" src="templates/documentRemoved.ftl" />
  	</extension>
	<extension target="org.nuxeo.ecm.platform.ec.notification.service.NotificationService" point="notifications">
	
		<notification name="Cancellazione" channel="email" availableIn="all" autoSubscribed="false"
          label="Cancellazione" template="remove">
          <event name="documentRemoved"/>
        </notification>

The event 'documentRemoved' is throwed when a document is permanently removed form the trash. What is your test case ?

Alice_

Where is the trash?

Clément_Lardeur

The trash is a sub-tab of the administration tab. When you press the button 'Delete' the 'documentRemoved' event is not fired, this is why the notification is not sended.

Alice_

Ok, thanks, now all has got sense! Could I bind the "documentRemoved" event to the "Delete" button?

Clément_Lardeur

There is no simply way to do that.

Alice_

Thanks, I will try to create a listener. Instead, is there an event associated to the moving of a document in the trash? I tried with "aboutToRemove", but it does not seem to work...and "lifecycle_transition_event" catch other events too (for example: restoring).

Clément_Lardeur

There is no event when a document is moved to the trash, but you should catch the event 'lifecycle_transition_event' and test if the currentLifeCycleState of the document is 'delete', then you can fired your own event 'documentDeleted'.

Alice_

Sorry, another question: if I move the "Permanently delete" button from the trash to the workspace with this piece of code:

<action confirm="if( !confirmDeleteDocumentsForever() ) return false;" help="comand.deleteDocs.help" icon="" id="CURRENT_SELECTION_DELETE" label="command.deleteDocs" link="#deleteActions.purgeSelection}">
  <category>CURRENT_SELECTION_LIST</category>
  <filter id="canPurge">
    <rule grant="true">
      <condition>#{deleteActions.canPurge}</condition>
    </rule>
  </filter>
</action>

I have the button, but it does not delete the document. Is there a way to fix it?

Alice_

Can I filter the notifications? Something like

Alice_

Well, thanks in any case, but I found a cleaner solution...I write it here, so, if someone will be interested... It is possible to disable the trash service, adding the following extension:

<extension point="config" target="org.nuxeo.ecm.webapp.trashManagement.TrashManagementService">
    <trashConfig enabled="false"/>
</extension>

Alice_

Testing the notification service for deleted files, I noticed that when a document has got more than one version, nuxeo send me a mail for each version when I delete the entire document... is there a way to filter to notifications?

Clément_Lardeur

You can use the method isVersion() of a DocumentModel in your listener to filter.

Implement a custom 'documentDeleted' event and create a listener for it to look at this:

Support For Instant Ink

@Component
public class DocumentService {
@Autowired private ApplicationEventPublisher publisher;

public void deleteDocument() {
// Delete logic
publisher.publishEvent(new DocumentDeletedEvent(this));
}
}
