[Zope3-Users] To Subclass, or to Adapt?

Thanks Stephan and Dominik for all the help so far.
I've decided to go down the route Stephan suggested,
since I was more able to get my head around it.
I've got a question about adapters / ZPT:
* Is is possible to access the output of an adapter
directly from ZPT?
My adapter provides a method getRating. I've used the
following to get it to also provide this as a
rating = property(getRating)
which seems to work. At the moment I am having to use
view/rating in my ZPT; the view class can say either:
rating = self.rate.getRating()
rating = self.rate.rating
depending on whether I want to access the method or
the property - both seem to work OK. However, I would
like to change from view/rating to context/rating or
context/getRating in the ZPT - this would seem cleaner
and more logical to me - I could do away with the view
class, so it would be one less piece of code to
My understanding of the adapter is that it has adapted
my object so it now provides the getRating() method
and rating property of the adapter interface - it
would seem to me that this should mean I can access it
like any other method or property the object provides,
but it does not seem to be the case.
