Re: [Zope3-Users] Weird behaviour of ViewPageTemplateFile()
class MyView(BrowserView):
def __call__(self):
pt = ViewPageTemplateFile('empty.pt')
data = pt()
return data
try this:
pt = ViewPageTemplateFile('empty.pt')
return pt(self)
Nope, same result:
AttributeError: 'str' object has no attribute 'other'
Cheers,

Re: [Zope3-Users] Weird behaviour of ViewPageTemplateFile()
Well, it's called a *View*PageTemplate for a reason :-) If the file is really empty and you do not need to pass any arguments to it (view, context, request), use a plain PageTemplateFile No, of course it's not empty and it needs the parameters. Nor does the view really look as trivial as the example. That was the minimal test case for the behaviour I could come up with. I still don't understand how the naming / storage of a variable holding the page template can influence the page rendering process.

Re: [Zope3-Users] Weird behaviour of ViewPageTemplateFile()
ViewPageTemplate must be in the view's namespace, and it magically fishes out the view, view's context and request, and makes them available in the TAL namespace. Ah, so there _IS_ heavy magic involved here. Thanks for clarifying that, I was already doubting my sanity!

Ah, so there _IS_ heavy magic involved here. Thanks for clarifying that, I was already doubting my sanity! This is exactly the same magic that methods use. ViewPageTemplateFiles are, like functions, meant to be used as methods and to be bound to instances. Okay, then this leads me to the strong suspicion that what I'm (mis)using ViewPageTemplateFiles for is the wrong way to attack the problem. What I'm doing is something along the lines of class MyView(BrowserView): def __call__(self): pagename = somehow_compute_new_page_name(self.request, self.context) pt = ViewPageTemplateFile(pagename) return pt.__get__(self, self.__class__)() but quite obviously, that's not how it's meant to be used, is it... Perhaps I need a radically different approach? Cheers, mjl ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users
