Share - Customize Description of a document

As we transition to the new Hyland Community, some post links may be temporarily disrupted as we finalize redirects. We apologize for the inconvenience and are working to resolve this as quickly as possible. Details.

Hello all

I have noticed that if a user enters a large description; the default view (when viewing all the documents in a space) shows all of it. I would like to add some logic that checks if the description is greater than say 200 characters; only the first 200 characters are displayed.

I am only just getting used to customizing share-documentlibrary-config.xml; but it seems I have to write additional logic to be able to perform this check. Any suggestions or links to if someone has attempted something along this line before?

As always, thanks a lot for all your input.

You can achieve this using metadata templates and Javascript renderers.

Code would be something similar to this:


share-config-custom.xml

    <config evaluator="string-compare" condition="DocumentLibrary">
        
        […]
        
        <metadata-templates>
            <template id="default">
                <line index="10" id="date" view="detailed">{date} {size}</line>
                <line index="20" id="myDescription" view="detailed">{myDescription}</line>
                <line index="30" id="social" view="detailed">{social}</line>
            </template>
        </metadata-templates>
        
        […]
    </config>
    <config evaluator="string-compare" condition="DocLibCustom">
        <dependencies>
            <js src="/js/myDescription.js" />
        </dependencies>
    </config>
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Then in tomcat/webapps/share/js/ create the myDescription.js file:

(function() {
   var $html = Alfresco.util.encodeHTML,
      $isValueSet = Alfresco.util.isValueSet;

   if (Alfresco.DocumentList)
   {
      YAHOO.Bubbling.fire("registerRenderer",
      {
         propertyName: "myDescription",
         renderer: function myDescription_renderer(record, label)
         {
            var jsNode = record.jsNode;
            var desc = "";
            if(jsNode.properties.description != undefined) {
                desc = jsNode.properties.description.substring(0, 200);
                if(jsNode.properties.description.length > 200) desc += " […]";
            }
            return '<span class="item">' + desc + '</span>';
         }
      }); 
   }
})();
