Noisy cm:content objects

sammasue

Hello everybody,

I recently created a Behaviour on cm:content / onCreateNode and I was really surprised to see how many objects of cm:content type or subtype are created. For example:
- page.title.user~admin~dashboard.xml
- page.full-width-dashlet.user~admin~dashboard.xml
- page.component-1-1.user~admin~dashboard.xml
- pdf {http://www.alfresco.org/model/content/1.0}thumbnail

And this is just a sample. I find all these objects really noisy. Indeed if I would like to do some treatment in a behaviour on cm:content I don't know what I going to modify. Thumbnail? document? some dashboard xml? And then what's happen if I modify these objects.

And I actually had one issue because I was modifying thumbnail (subtype of cm:content) I broke document previous.

I would expect in that case to work only on my documents I uploaded. Any idea how to filter? It is quite easy to filter subtypes but unfortunately some nodes are cm:content.

Thanks in advance for any help,

Sam

Hi,
The following types are skipped in the search results by default: cm:thumbnail, cm:failedThumbnail, cm:rating and aspect sys:hidden.
If you want to use behavior for cm:content then you need to skip all system files. You can do it by adding the condition into the code. Something like that:



    @Override
    public void onCreateNode(ChildAssociationRef childAssocRef) {

                if (applicable(childAssocRef.getChildRef())) {

                    onCreateNodeImpl(childAssocRef);

                }

    }


    protected boolean applicable(NodeRef nodeRef) {
        return getNodeService().exists(nodeRef) &&
                !getNodeService().hasAspect(nodeRef, RenditionModel.ASPECT_HIDDEN_RENDITION) &&
                !getNodeService().hasAspect(nodeRef, ContentModel.ASPECT_HIDDEN) &&
                !getNodeService().getType(nodeRef).equals(ForumModel.TYPE_FORUM) &&
                !getNodeService().getType(nodeRef).equals(ForumModel.TYPE_POST) &&
                !getNodeService().getType(nodeRef).equals(ForumModel.TYPE_FORUMS) &&
                !getNodeService().getType(nodeRef).equals(ForumModel.TYPE_TOPIC)
    }

Hi,

Thank you very much S.Palyukh for your help. Unfortunately I have tried to see if these documents had any "hidden" aspects but they don't (I am using Alfresco 5.0.c). Here the code I used:

@Service
@BehaviourBean
public class ApplyConfidentiality implements NodeServicePolicies.OnCreateNodePolicy
{
  @Autowired
  @Qualifier("NodeService")
  private NodeService nodeService;

  /**
   * Called when a new node has been created.
   *
   * @param childAssocRef the created child association reference
   */
  @Behaviour(
    kind = BehaviourKind.CLASS,
    type = "cm:content")
  @Override
  public void onCreateNode(ChildAssociationRef childAssocRef)
  {
    
    if (ContentModel.TYPE_CONTENT.equals(nodeService.getType(childAssocRef.getChildRef())))
    {
      System.out.println("CM:CONTENT");
    }else
    {
      System.out.println("CM:CONTENT subType");
    }

    for (QName qName : nodeService.getAspects(childAssocRef.getChildRef()))
    {
      System.out.println(qName.getLocalName());
    }

    if (nodeService.hasAspect(childAssocRef.getChildRef(), RenditionModel.ASPECT_HIDDEN_RENDITION))
    {
      System.out.println("REDITION HIDDEN");
    }

    if (nodeService.hasAspect(childAssocRef.getChildRef(), ContentModel.ASPECT_HIDDEN))
    {
      System.out.println("ASPECT HIDDEN");
    }
  }
}

I have got only these aspects :
auditable
referenceable
localized

Just a guess, have you tried filtering by cm:creator or cm:modifier ?

I found how rules work in alfresco , they also use a behavior to start executing (look at the RuleTriggerAbstractBase class):

   /** the types (hardcoded) to ignore generally */
    private static final Set<QName> IGNORE_TYPES;
    /** the aspects (hardcoded) to ignore generally */
    private static final Set<QName> IGNORE_ASPECTS;
    static
    {
        IGNORE_TYPES = new HashSet<QName>(13);
        IGNORE_TYPES.add(RuleModel.TYPE_RULE);
        IGNORE_TYPES.add(ActionModel.TYPE_ACTION);
        IGNORE_TYPES.add(ContentModel.TYPE_THUMBNAIL);
        // Workaround to prevent rules running on cm:rating nodes (which happened for 'liked' folders ALF-8308 & ALF-8382)
        IGNORE_TYPES.add(ContentModel.TYPE_RATING);
        IGNORE_TYPES.add(ContentModel.TYPE_SYSTEM_FOLDER);

        IGNORE_ASPECTS = new HashSet<QName>(13);
        IGNORE_ASPECTS.add(ContentModel.ASPECT_TEMPORARY);
    }

    protected void triggerRules(NodeRef nodeRef, NodeRef actionedUponNodeRef)
    {
        // Break out early if rules are off
        if (!areRulesEnabled())
        {
            return;
        }

       // Do not trigger rules for rule and action type nodes
       if (ignoreTrigger(actionedUponNodeRef) == false)
       {
           for (RuleType ruleType : this.ruleTypes)
           {
               ruleType.triggerRuleType(nodeRef, actionedUponNodeRef, this.executeRuleImmediately);
           }
       }
    }

    /**
     * Indicate whether the trigger should be ignored or not
     * @param actionedUponNodeRef     actioned upon node reference
     * @return boolean              true if the trigger should be ignored, false otherwise
     */
    private boolean ignoreTrigger(NodeRef actionedUponNodeRef)
    {
       boolean result = false;       
       QName typeQName = nodeService.getType(actionedUponNodeRef);
       if (IGNORE_TYPES.contains(typeQName))
       {
          result = true;
       }
       for (QName aspectToIgnore : IGNORE_ASPECTS)
        {
            if (nodeService.hasAspect(actionedUponNodeRef, aspectToIgnore))
            {
                return true;
            }
        }
       return result;
    }

This code is from Alfresco 4.1.5

Hello,

I have tried this and it seems to work pretty well. I have improved a bit to ignore as well nodes used for the "surf-config". My result looks like this.

/**
&nbsp;&nbsp; * the types to ignore generally (see RuleTriggerAbstractBase)
&nbsp;&nbsp; */
&nbsp; private static ImmutableSet<QName> IGNORE_TYPES = ImmutableSet.<QName>builder()
&nbsp;&nbsp;&nbsp; .add(RuleModel.TYPE_RULE)
&nbsp;&nbsp;&nbsp; .add(ActionModel.TYPE_ACTION)
&nbsp;&nbsp;&nbsp; .add(ContentModel.TYPE_THUMBNAIL)
&nbsp;&nbsp;&nbsp; .add(ContentModel.TYPE_RATING)
&nbsp;&nbsp;&nbsp; .add(ContentModel.TYPE_SYSTEM_FOLDER)
&nbsp;&nbsp;&nbsp; .build();

&nbsp; /**
&nbsp;&nbsp; * the aspects to ignoreForBehaviour generally (see RuleTriggerAbstractBase)
&nbsp;&nbsp; */
&nbsp; public static ImmutableSet<QName> IGNORE_ASPECTS =
&nbsp;&nbsp;&nbsp; ImmutableSet.<QName>builder().add(ContentModel.ASPECT_TEMPORARY).build();

&nbsp; /**
&nbsp;&nbsp; * (see RuleTriggerAbstractBase)
&nbsp;&nbsp; * determine if the node has to be ignored for a behaviour*
&nbsp;&nbsp; *
&nbsp;&nbsp; * @param nodeRef ref of the node
&nbsp;&nbsp; * @return true if the node should be ignored, false otherwise
&nbsp;&nbsp; */
&nbsp; public boolean ignoreForBehaviour(NodeRef nodeRef)
&nbsp; {
&nbsp;&nbsp;&nbsp; if (IGNORE_TYPES.contains(nodeService.getType(nodeRef)))
&nbsp;&nbsp;&nbsp; {
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; return true;
&nbsp;&nbsp;&nbsp; }
&nbsp;&nbsp;&nbsp; for (QName aspectToIgnore : IGNORE_ASPECTS)
&nbsp;&nbsp;&nbsp; {
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; if (nodeService.hasAspect(nodeRef, aspectToIgnore))
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; {
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; return true;
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; }
&nbsp;&nbsp;&nbsp; }
&nbsp;&nbsp;&nbsp; 
&nbsp;&nbsp;&nbsp; return isSurfConfig(nodeRef);
&nbsp; }

&nbsp; /**
&nbsp;&nbsp; * Check if the node is inside a surf-config folder (E.g. of files in the surf-config folder dashboard.xml)*
&nbsp;&nbsp; * @param nodeRef ref of the node to check
&nbsp;&nbsp; * @return true if it's surf-config file otherwise false
&nbsp;&nbsp; */
&nbsp; private boolean isSurfConfig(NodeRef nodeRef)
&nbsp; {
&nbsp;&nbsp;&nbsp; if(nodeRef != null && nodeService.exists(nodeRef))
&nbsp;&nbsp;&nbsp; {
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; if ("surf-config".equals(nodeService.getProperty(nodeRef, ContentModel.PROP_NAME)))
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; {
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; return true;
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; }
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; return isSurfConfig(nodeService.getPrimaryParent(nodeRef).getParentRef());
&nbsp;&nbsp;&nbsp; }
&nbsp;&nbsp;&nbsp; return false;
&nbsp; }
