[Zope] return structured result from Python scripts for page templates

Thu, 25 Jul 2002 15:35:54 +0200

Oops, it was my mistake. The dictionary solution works! I do not know, 
why has it failed for the first time.
I think the stuff is interesting enough to explain short the solution here.
So the solution is:

Python script get_persons:

result = []

result.append({'name':'Jack','title':'Mr.'})
result.append({'name':'Joe','title':'Mr.'})
result.append({'name':'Mary','title':'Ms.'})

return result

A possible page template:
<html>
   <head>
     <title tal:content="template/title">The title</title>
   </head>
<body>
<table>
<tr tal:repeat="item container/get_persons">
<td tal:content="item/name">Kate</td>
<td tal:content="item/title">Mrs.</td>
</tr>
</table>
</body>
</html>
