You don't have to create the page template as an attribute of a class. 
You can declare it as a local variable

pt = ZopeTwoPageTemplateFile('template.pt')

and then do

extra_context = {'context': some_context}
html = pt.pt_render(extra_context=extra_context)

The context variable in your template will then be what you want it to be.

If you still encounter security problems then add this line directly 
after you declare class AdhocContext

__allow_access_to_unprotected_subobjects__ = 1

You probably should not use that line too often :)
