Hi;

I have the following block of code:

<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:content="item/title">title</td>
    <td tal:content="item/bobobase_modification_time">
      modification date</td>
    <td tal:content="here/author">author</td>
    <td tal:content="here/content">content</td>
</tr>
</table>

that works fine. But I'd like to call the following in that table:

<td><tal:content metal:use-macro="here/XXX/macros/author"></tal:content></td>

where "XXX" is the "item" that changes each time a new item from the batch is called. In other words, there is a folder with a "batch" of files, and each file is an "item". So, since the files' titles are simply sequential numbers, it would look something like this:

<td><tal:content metal:use-macro="here/1/macros/author"></tal:content></td>
<td><tal:content metal:use-macro="here/2/macros/author"></tal:content></td>
<td><tal:content metal:use-macro="here/3/macros/author"></tal:content></td>
...

How do I do that? Even better, is it possible to just open up each file and read its contents??

Thanks,

Ben

Ben,
First this is wrong:

<td><tal:content ...

If should be
<td tal:content ...

But that may be wrong in the context you've given.

Since "do it in python" has been a theme lately, you can also return a macro from a python script like so:

Where there is an author might be a parameter.
#some python script
#
return container.YourMacroFolder.someMacro[ author ]
-----------------------------------------------------------------------

And in your ZPT: (where result.author is just a stub for whatever your using)

<td><span metal:use-macro="python: context.youPythonScript(result.author)">macro goes here</span></td>

I suggest *always* doing stuff in python when things are not clear. Then code back into your Page Templates, if desired
