forgive me if it's trivial, but I'm a complete zope newbie....
You must also learn how to formulate questions :-)
... I read in the zope book that if I want to call zpt from a script (in my case, to render errors in a form) I do something like this:
-- script:
pt = context.body_content s = pt(zerror="This is an error") return s
zpt:
<i tal:content="options/zerror | default">error</i> --
This works without a problem, but it only shows the "body_content" file. this file is part of a layout (inside a folder) and I want to call the folder as the url, so it will acquire the index_html in an upper directory.
I do not yet understand what you want... Usually, the overall layout is defined in a macro and individual page templates use this macro and fill slots of it. Maybe, you read about "metal:define-macro", "metal:define-slot", "metal:use-macro" and "metal:fill-slot" in the Zope Book. Otherwise, if you do not want to call "body_content" but "index_html", then you simply use "pt = content.index_html" (provided it is a ZPT, too).
I tried changing the "pt" variable to context.index_html and calling "here/index_html/options/zerror" in the template but it didn't show.
In "index_html", you would access "zerror" also via "option/zerror". When your "index_html" would call "body_content", you would need to pass "zerror" again. -- Dieter
