...I read the ZPT source and figured I could do the following:

instance.manage_addProduct['PageTemplates'].manage_addPageTemp late('index_html') instance['index_html'].write(instance.memberIndex.document_src(self))

but no, I get:

Error Type: Unauthorized Error Value: You are not allowed to access document_src in this context

I am logged in as 'manager'. I have tried:

instance['index_html'].write(str(instance.memberIndex)) where memberIndex is a regular file and this works fine, but I want to use a model ZPT.

1) method document_src() requires no parameters (self is passed implicitly by python) So you may write context['index_html'].write(context.memberIndex.document_src()) 2) To create a page template with a content, you may pass it in constructor: container.manage_addProduct['PageTemplates'].manage_addPageTemplate('ind ex_html', text=context.memberIndex.document_src()) Enjoy :) Dmitry
