[Zope] dtml-in output if no objects are found

[Kevin Carlson]

Here's one way to do it:

[in this example, "query" is what you want to iterate over in the eventual
<dtml-in>

<dtml-let results="query">
<dtml-if "_.len(results) > 0">
   <dtml-in results>
     ... do whatever ...
   </dtml-in>
<dtml-else>
  ... do whatever ...
</dtml-if>


Hope that helps,

Kevin

I have a dtml-in that pulls in two different types of objects and
outputs data from them accordingly. I want to output a message if no
objects of this type were found. Is there a direct way to do this?
