Moving when a file already exists with that name

dallinns

I have a webscript set to move a file to a different folder. If, for example, I have a file named "dog.jpg" and I move it into a different folder that already has a file named "dog.jpg" then the script will just time out. I tried to catch the error and then do something else, but it just seems to time out rather than return false when there is a problem with the .move function.

my script looks like this:

destNode = search.findNode("workspace://SpacesStore/"+url.templateArgs.destNodeId);

nodeToMove = search.findNode("workspace://SpacesStore/"+url.templateArgs.nodeToMoveId);

var success = nodeToMove.move(destNode);

if(success){
   nodeToMove.save();
}else{

   var originalName = nodeToMove.name;
   for(var i = 1; !success; i++){
      nodeToMove.name = originalName + '('+i+')';
      nodeToMove.save();
      success = nodeToMove.move(destNode);
   }
   nodeToMove.save();
}
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Does anyone know how I can handle this situation? How can I force a rename when there is already an existing file with that name?

Check whether the destination path exists first. I think that will get you around your immediate problem.

May also be worth raising an enhancement JIRA so this can be considered.

Ok, so now I am trying this:

destNode = search.findNode("workspace://SpacesStore/"+url.templateArgs.destNodeId);

nodeToMove = search.findNode("workspace://SpacesStore/"+url.templateArgs.nodeToMoveId);

var childrenAtDest = destNode.children;

var alreadyExists = false;
var counter = 1;
var originalName = nodeToMove.name;
var nameToCheck = originalName;

model.whatever = Array();
model.original = originalName;

do{
   for(var j = 0; j < childrenAtDest.length; j++){
      
      if(childrenAtDest[j].name == nameToCheck){
         
         alreadyExists = true;
         
      }
      model.whatever.push(childrenAtDest[j].name + " vs " + nameToCheck + ": " + alreadyExists);
   }

   if(alreadyExists){
      nameToCheck = originalName+'('+counter+')';
      counter++;
   }else if(originalName != nameToCheck){
      nodeToMove.name = nameToCheck;
      nodeToMove.save();
   }
}while(alreadyExists);

nodeToMove.move(destNode);‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

and i'm outputting the results and looking at the names but the if statement that compares them never evaluates to true. Why is that?

Hi, I have copied and added above script in alfresco.
And trying to apply it on folder via rule. But it is giving error in Catalina log file like
ReferenceError: "url" is not defined. (workspace://SpacesStore/0b0aec0b-8856-42af-8ace-8a9460426c4b#1)

Can anyone help me out from this? How i can set url?

Hi,
You can refer, how alfresco is handling the duplication file uploads, in upload.post.js file; You can follow the similar approach in your code.
Below the snippet for the same.



/**
          * Existing file handling.
          */
          
/ Upload component was configured to find a new unique name for clashing filenames
               var counter = 1,
                  tmpFilename,
                  dotIndex;

               while (existingFile !== null)
               {
                  dotIndex = filename.lastIndexOf(".");
                  if (dotIndex == 0)
                  {
                     // File didn't have a proper 'name' instead it had just a suffix and started with a ".", create "1.txt"
                     tmpFilename = counter + filename;
                  }
                  else if (dotIndex > 0)
                  {
                     // Filename contained ".", create "filename-1.txt"
                     tmpFilename = filename.substring(0, dotIndex) + "-" + counter + filename.substring(dotIndex);
                  }
                  else
                  {
                     // Filename didn't contain a dot at all, create "filename-1"
                     tmpFilename = filename + "-" + counter;
                  }
                  existingFile = destNode.childByNamePath(tmpFilename);
                  counter++;
               }
               filename = tmpFilename;

When you're running the script via folder rule, you will not get url context in the script.
I believe, you can use <strong> document </strong> variable to get the document / folder node reference.
Please let me know, if this is not helping you.
