[Grok-dev] FW: grok 1.0 and forbidden attribute error

[Lacko Roman]

Hi,

Sorri, this is more complete template:
>>>
  <tal:block tal:repeat="file view/Files" tal:condition="view/Files">
    <div class="container doc_desc_container">
      <div class="doc_desc">
        <a tal:content="file/getFileBaseName"
          tal:attributes="href string:${view/application_url}/files/${file/__name__}/display/@@file/File/${file/getFileBaseName}">
          Title
        </a>
        -- <p tal:define="sizekb python:file.File.getSize()/1024" tal:replace="sizekb">100</p> KB
      </div>
    </div>
  </tal:block>
<<<

The @@file view is from collective.namedfile package and returns the DocumentFile instance.

The ${view/application_url}/files returns grok.Container which contains instances of DocumentFile class

It's just strange that this worked for in grok 0.14 but not in 1.0

I just want to create url to file like object, so users can download file, that is stored in zodb.
But i'm shore there is better way to do it ? 

Thanks for your help
- Roman
