Hello
When displaying the query in a table, I want to display a custom
message if the result is empty.
For now I do this :
in my controller
elements=model.DBSession().query(model.Elements)
in my template
<p py:if="not elements.first()">The list is empty</p>
<table py:if="elements.first()">
<tr><th>Name</th></tr>
<tr py:for="elem in elements"><td>${elem.name}</td></tr>
</table>
but this generate 3 request to the SQL server !
Is it possible to avoid this ?
Regards
