Getting path to a folder through freemarker template in alfresco

[juilee]

Hi, would like to get the path to all the sub-folders of a parent folder, from a freemarker template.

I tried the following, but it throws error not able to find the node: "${url.serviceContext}/api/node/content/workspace/SpacesStore/{child.nodeRef.id}/{child.name}"

"${url.serviceContext}/api/node/content/${child.nodeRef.storeRef.protocol}/${child.nodeRef.storeRef.identifier}/${child.nodeRef.id}/{child.name?url}"


Am I missing something ?


Thanks

JS file :

function main()
{ 
   var results = [];
   
   if(args["nodeRef"] != null) {
   
   var objNodeRef = search.findNode(args["nodeRef"]);
   var nodeChilds = [];
   
   if(objNodeRef != null) {
      nodeChilds = objNodeRef.children;
      
      for each (var result in nodeChilds)
      {
          
             var resultObj = 
             { 
                 item: result
             };
             resultObj.selectable = "true";
             results.push(resultObj);
          
      }
   }
   }
   model.results = results;   
}

main();
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

JSON Response file code :

{
   "data":
         {
           "items":
                  [
                     <#list results as row>
                        {
                           "name": "${row.item.properties.name!""}",
               
                           "type": "${row.item.typeShort}",
                           "isContainer": ${row.item.isContainer?string},
                        
                           <#if row.item.properties.title?exists>
                              "title": "<#escape x as jsonUtils.encodeJSONString(x)>${row.item.properties.title!""}</#escape>",

}

You just need to add one more desc file along with above two files.

<webscript>
  <shortname>Get children</shortname>
  <description>Get children details</description>
  <url>/api/folder/getchildren</url>
  <format default="json"/>
  <authentication>user</authentication>
  <transaction allow="readonly">required</transaction>
</webscript>

Hi Sanket,

Thanks a lot for the detailed answer.
I am relatively new to alfresco so this might sound little silly but as far as I understand, we can display contents using freemarker template in alfresco. To process the JSON response received, I should iterate over the results variable in a freemarker template to display the contents. Is that correct?

Also earlier I was passing the path of the folder in the url as:
http://localhost:8080/alfresco/service/sample/folder/path.
And it would be taken by the js as
var folder = roothome.childByNamePath(url.extension);
In this case, how do we pass the args?

And out of the variables we get in the JSON response, which would give the exact path to the folder (not the display path but actually will take the user to the folder by clicking on it). Earlier I had tried node.url, node.downloadUrl, node.nodeRef, etc but none takes me to the folder.

I would appreciate your help on this.

Regards,
Juilee

Hi
You are right that freemarker is used for display contents which you can produce by Javascript file. By freemarker you can make json, xml, html or what type of response you need. In freemarker you can iterate with

<#list>‍

.. Here is manual for it http://freemarker.org/docs/ref_directive_list.html .

You can pass arguments there by adding to url

http://localhost:8080/alfresco/service/sample/folder/path?yourArg=yourArg‍

and in Javascript you can get it by

args.yourArg‍

.
It is good to specify what arguments there should be in webscript in

.desc.xml‍

file like this

<webscript>
  <shortname>Get children</shortname>
  <description>Get children details</description>
  <url>sample/folder/path?yourArg={yourArg}</url>
  <format default="json"/>
</webscript>
‍‍‍‍‍‍‍

About that url. I had some days ago same problem and I havent found how to get that link so I made it by myself. I dont know if it is good aproach but I havent found anything better.

yourNodeRef.displayPath.replace("Company Home/", "")‍

this will give you filter so you can pass it like link:

'<a href="repository#filter=path|' + pathFromWebscript + '">'‍

[sanket]

If you are using alfresco share, then the exact url pointing to the folder should be something like : (provided I have created this folder hierarchy in my repository - CD > ABC
http://localhost:8080/share/page/repository#filter=path%7C%2FCD%2FABC%7C&page=1
Lets say if your folder hierarchy is something like : One > Two  , then your URL would be like :
http://localhost:8080/share/page/repository#filter=path%7C%2FOne%2FTwo%7C&page=1

So you need to append the alfresco url as prefix to your path.

But, if you are using alfresco explorer (and not alfresco share), then your url directly to the folder would require folder nodeRef.
Something like :
http://localhost:8080/alfresco/n/browse/workspace/SpacesStore/f7af6b49-3296-4474-853b-db357061c53b

So again, append the alfresco url as prefix to the nodeRef
NOTE: Your nodeRef contains ':/'. You need to remove ':/' from the nodeRef and then put it in the url.
Actual nodeRef  : workspace://SpacesStore/f7af6b49-3296-4474-853b-db357061c53b
NodeRef appended in url : workspace/SpacesStore/f7af6b49-3296-4474-853b-db357061c53b

Hi Sanket,

Thanks ! I am using Alfresco share and I did the same thing as you mentioned for the share part. I was just wondering if that is the right way to do it OR is there a better way?
