[Zope] Keeping a Variable's Value: This SHOULD Be Easy

Tue, 30 Oct 2001 22:59:05 +0100

This SHOULD...

Unfortunately the ways to keep a python object's value while processing DTML
are "buzzy":

1/ Use the REQUEST mapping object
<dtml-call "REQUEST.set('foo', something)">
HTML/raw text/XML blah blah
<dtml-var "REQUEST['foo']>

2/ Get HappySession or another user session management product to keep the
value between two requests

In both cases, unfortunately, you can use only one python expression to
initialize the value
