Is it possible (and how?) to use a procedure in a product to produce a PageTemplate that defines a macro, that can be used in another PageTemplate?

I tried:

class SomeClass(Folder):

content_template = PageTemplateFile("/some/file/template.zpt")

and the direct ssignment to a variable works, but it is not exactly what I need (I need to check with the actual instance).

But when I try to do:

def content_template(self): pt = PageTemplateFile("/some/file/template.zpt") return pt

then the procedure is never called and I get an error in the ZPT that tries to use the macro:

Error Type: AttributeError Error Value: content_templatemacros

Somewhere I read a vage reference to invoke "cook" but I don't know how.

Read the answer I already gave to your identical mail (yesterday?) :-) Regards Tino

Two errors: 1. as Tino already pointed out: you forgot the ".__of__(self)" 2. you must call your "content_template" method (contrary to your "content_template" attribute). The easiest way would be a "ComputedAttribute", something like from ComputedAttribute import ComputedAttribute ... def content_template(self): ... content_template = ComputedAttribute(content_template, 1)

Somewhere I read a vage reference to invoke "cook" but I don't know how.

PageTemplates get automatically "cook"ed, when necessary. -- Dieter
