[Zope] RE: ZPT Print Theme

24 Dec 2002

      ...
Here's how I do it...
Here's the first line of my index_html...
<html metal:use-macro="here/getTemplate">
'getTemplate' is a python-script, consisting of...
request = container.REQUEST
if request.has_key('pp'):
return context.standard_print_template.macros['master']
else:
return context.standard_template.macros['master']
It seems to be right, but, unfortunately, it does not work.

What I hase:
main_template - normal Page Template like this:

<html metal:define-macro="page">
  <body>
    <span metal:define-slot="body" tal:omit-tag="">
       Body....
    </span>
  </body>
</html>

and many other page templates that call it:

<html metal:use-macro="container/templates/freehand.pt/macros/page">
<span metal:fill-slot="body">
<!-- ... -->
</span>
</html> 

You recomend me change main_template to python script:
## Script (Python) "main_template"
##bind container=container
##bind context=context
##bind namespace=
##bind script=script
##bind subpath=traverse_subpath
##parameters=
##title=
##

request = container.REQUEST

if request.has_key('print'):
    return context.print_template.macros['page']
else:
    return context.normal_template.macros['page']
-------------------------------------------------

Now, when I try to render pages I have an error:

Undefined

with traceback:
[....skip....]

Or in ZMI with checked "Expand macros when editing" flag:

Macro expansion failed
Products.PageTemplates.TALES.Undefined: macros not found in

What I do wrong and can that problem be resolved in this direction?
