[Zope] Re: Testing arguments in zsql methods

[Pablo Ziliani]

Hi again,
for the records, replying my own recent post:
the way to test if a variable exists in a zsql method is through has_key 
NOT hasattr.
In other words: <dtml-if "_.has_key('foo')">...</dtml-if>

Sorry for bothering, it's been a long time not dealing with dtml....
