[Zope] DTML w/o acquisition?

[Dylan Reinhardt]

Try this:

def show_stuff(self):
    """obligatory doc string"""
    return DTMLFile(file_name, globals()).__of__(self)()

Or, if you prefer, the ZPT version:

from Products.PageTemplates.PageTemplateFile import PageTemplateFile

def show_stuff(self):
    """obligatory doc string"""
    return PageTemplateFile(file_name, globals()).__of__(self)()

Trust me, you don't want to go about implementing your own templating 
system.  It sucks.

HTH,

Dylan
