Re: [Zope] Call PageTemplateFile class instances
I've kind of work it out. The trick is to write some boiler plate in
the class definition like this::
from zope import traversing, component, interface
from zope.interface import implements
from zope.traversing.interfaces import ITraversable
from Products.PageTemplates.PageTemplateFile import PageTemplateFile
class MyProduct(Folder):
implements(ITraversable)
component.provideAdapter(
traversing.adapters.DefaultTraversable,
(interface.Interface,),ITraversable)
meta_type = bla
page = PageTemplateFile('zpt/foo.pt', globals())
def render_page(self):
html = self.page(self.REQUEST) # ERROR!!
I don't understand how it works and I wish there was a way to apply
these settings from a function instead of having to copy and paste it
into every instance creating class.

2.10.7 to be exact)

The error is ridiculously large so I've truncated it:

why do you do this double shuffle anyway, when you can directly call
page and protect it if necessary...
I certainly don't have the issue you're describing and I don't need to
do all that implements garbage either.
Are you sure you don't have some Product installed that's messing with
it?

No I'm not sure.
Truth is that my product is more complicated than that but so I took a
risk thinking it'll be the same as the pseudo product code I wrote.

No difference if I pass REQUEST or not. :(
