[Zope] variable propagation
Hi, I would like to ask how to propagate variables from initial index_html call to deeper levels. Say I have index_html python script, I invoke it then I would like to feed some data to generic template, that will in turn will invoke template in the same directory that will do nice layout of my results. Generic template lies below all other objects, in directory tree, in the root. When I execute the command chain, variables are not passed and options is lost on one layer of zpt calls. Is there way to rectify that.

Pavel,
You question is a bit vague but ...
Make your index_html a python script. And then stuff your REQUEST with
info you want
Then just call the Page Template ...
request.set('formvar1', somevalue)
return context.myPageTemplate(context.request)
Of course of you have forms submit with an action=. and method=post.
Then you can intercept all calls using index_html, do what you need to
do and *then* render the next form.

here is description:
root/
index_html
index_tmpl -- invokes here.content_html
root/some/web/page
index_html -- overriding root one, calls -- context.index_tmpl(some
parameters=some parameters).
content_html -- gets called from index_tmpl
So i want parameters that are presented to index_html be presented to
context_html just like they would be presented to index_html.
So i would be able to call context_html from outside as well from the
inside. Ie span tal:replace=username/ should work in both
cases. I thought thats the way zope's code reuse works.
Thanks

Pavel,
How are you invoking templates? Give code snippets.
Have you read the "Advanced Scripting" section in the Zope book?
Plope.com has a the latest version (i think).
