NodeRef syntax in JavaScript API

[simon]

Hi Alfresco,

I'm trying to add categories to a document but started with a locale as this seems less complex to start with. Problem is I need to assign a nodeRef to the property but how should this nodeRef look like? In the node browser a nodeRef looks like workspace://SpacesStore/666345ce-1d81-11db-b398-13c0b9d26600 but it isn't accepted in my JavaScript. What am I doing wrong?

var folder = companyhome;
var copy = document.copy(folder);
if (copy != null)
{
   copy.name = "new_";
   // Add the English category to the document
   var nodeRef = "workspace://SpacesStore/666345ce-1d81-11db-b398-13c0b9d26600";
   document.properties["cm:locale"] = nodeRef;
   copy.save();
}‍‍‍‍‍‍‍‍‍‍

The JavaScript API does not deal with NodeRef values - everything is wrapped in an OO style API, so it deals with scriptable Node objects. This means any 'd:noderef' property value should be assigned a Node object directly.

So you need to get hold the Node that represents your category - by query i expect or from an existing Node that has the category you need already assigned.

var folder = companyhome;
var copy = document.copy(folder);
if (copy != null)
{
   copy.name = "new_";
   // Add the English category to the document 
   var node = search.luceneSearch(……)[0];
   document.properties["cm:locale"] = node;
   copy.save();
}

Thanks,

Thanks Kevin, it works like it should! I can add a locale with JavaScript now. One small extra question… how to realize this for collection aspects, the generalclassifiable for example?

var nodeRef = search.luceneSearch("TYPE:\"{http://www.alfresco.org/model/content/1.0}category\" AND  PATH:\"/cm:generalclassifiable//cm:MyCategory\"")[0];
copy.properties["cm:generalclassifiable"] = nodeRef;
‍‍‍

Doesn't work because the copy.properties excepts a collection element. Tried to remove the index ([0]) at the end of the nodRef and to add an index at the end of the copy.properties but this doesn't solve it.

How do I add this nodeRef without removing the other categories?

The 1.4 JavaScript engine now correctly supports multi-value properties - so you will be able to do this:

var categories = new Array(1);
var nodeRef = search.luceneSearch("TYPE:\"{http://www.alfresco.org/model/content/1.0}category\" AND  PATH:\"/cm:generalclassifiable//cm:MyCategory\"")[0];
categories[0] = nodeRef;
// … add further categories here to the array
copy.properties["cm:generalclassifiable"] = categories; 
‍‍‍‍‍‍‍

So to set a multi-value property, you simply fill an array with the appropriate object type and assign that.

Thanks,

Kevin

Thanks Kevin, again something that I'll try out once we get to the 1.4 release.
