Creating categories from Javascript

samuel_penn — Thu, 08 Jan 2009 15:26:52 GMT

Hi,I'm currently having a look at what can be done with categories, and from I can see, it should be possible to create a new classification scheme outside of cm:generalclassifiable, and add categories and sub-categories to this with the Javascript API. However, I'm having issues getting my head aro

I managed to populate my tree using a webscript by first creating the category root node in a separate transaction:


var check = search.luceneSearch("@cm\\:name:\"MYCLASSIFICATION\" AND TYPE:\"category\"");
if(check.length == 0) {
    // /{http://www.alfresco.org/model/content/1.0}categoryRoot
    var root = search.luceneSearch("@cm\\:name:\"categories\" AND TYPE:\"category_root\"")[0];
    root.createNode("MYCLASSIFICATION", "{http://www.alfresco.org/model/content/1.0}category", "cm:categories");
}
‍‍‍‍‍‍‍‍

I first check if this initialization was already correctly done, if not I create a childnode in the category_root node with the name categories with the associationtype categories.

this part should be work

var props = new Array();
                  props["cm:name"] = categoryName;
                  if(categoryDescription!=null){
                     props["cm:description"] = categoryDescription
                  }
                  model.newNode = nodeParent.createNode(categoryName, "{http://www.alfresco.org/model/content/1.0}category", props, "cm:subcategories");‍‍‍‍‍‍

and here's the complete javascript

var parentNodeRef = args.categorynoderef;
var categoryName = args.name;
var categoryDescription = args.description;
var rootNodeRef = args.rootcategorynoderef;
var resultString = "Action failed";
var resultCode = 501;
try {
   if ((categoryName == null) || (categoryName == "")) {
      resultString = "Category must have a Name";
   }  else {
      if ((parentNodeRef != null) && (parentNodeRef != "")) {
         var nodeParent = search.findNode(parentNodeRef);
         if (nodeParent != null) {
            //Check if already exists a category with the same name as the given one
            var root = search.findNode(rootNodeRef);
            if (root != null){
               var query = "+PATH:\""+root.qnamePath+"//*\" +TYPE:\"cm:category\"";
               query += " +@cm\\:name:\""+categoryName+"\"";
               var nodes = search.luceneSearch(query);
               var nodeExists = false;
               for each(node in nodes) {
                  if (node.name == categoryName) {                   
                     nodeExists = true;
                     break;
                  }
               }
               if (nodeExists){
                  //Already exists with same name
                  resultString = "Category with the name '"+categoryName+"' already exists.";
               } else {
                  //Doesn't exist, then create it
                  var props = new Array();
                  props["cm:name"] = categoryName;
                  if(categoryDescription!=null){
                     props["cm:description"] = categoryDescription
                  }
                  model.newNode = nodeParent.createNode(categoryName, "{http://www.alfresco.org/model/content/1.0}category", props, "cm:subcategories");
                  resultString = "New category created";
                  resultCode = 200;
               }
            } else{
               resultString = "Invalid root node";
            }
         } else {
            resultString = "Invalid parent node";
         }
      } else {
         resultString = "Invalid param";
      }   
   }
} catch (e) {
   resultString = "Action failed due to an exception: "+e.toString();
}
model.resultString = resultString;
model.resultCode = resultCode;
