[Zope] Newbie: Missing a Variable (TAL/METAL Question)

Fri Jul 28 18:43:34 EDT 2006

Dieter Maurer <dieter at handshake.de> wrote:If you use "repeat/variable" (again, "variable" is not meant literally,
but *some* "variable"), then "variable" must be a repeat variable
defined by an enclosing 'tal:repeat="variable ..."'.
If this is the case, then "repeat/variable/number" should work.
Here is the code again:

<table tal:define="objects here/objectValues;
                   sort_on python:(('title', 'nocase', 'asc'),
                                   ('bobobase_modification_time', 'cmp', 'desc'));
                   sorted_objects python:sequence.sort(objects, sort_on);
                   start python:getattr(request, 'start', 0);
                   batch python:modules['ZTUtils'].Batch(sorted_objects, size=10, start=start);
                   previous python:batch.previous;
                   next python:batch.next">
  <tr tal:repeat="item batch">
    <td tal:define="number repeat/item/number"
            tal:content="number">1</td>
    <td tal:content="item/title">title</td>
    <td><tal:content metal:use-macro="here/?number/macros/author">author</tal:content></td>
    <td><tal:content metal:use-macro="here/?number/macros/content">content</tal:content></td>
    <td tal:content="item/bobobase_modification_time">
      modification date</td>  
  </tr>
</table>

Here is the error it throws as reported through the TTW:

The error from the error log makes no sense to me. The time is off, too. I don't understand, but here it is:
