But I'm not accessing it via a url.  Consider the example I referred to at
http://quixote.ca/qx/QuixoteAndSimpleTalAdvanced

So I change the basic application to look like this:

from quixote.quixote_tal import Template, TemplateMethod
from new import instancemethod

_q_exports=['page', 'bill']

# creates a stand alone web page
page=Template('/users/chriseb/www/photo/exp/page.html')

class Person:
    """
    Example class that uses a template to display instances
    """
    _q_exports=['name', 'books']

    def __init__(self, name):
        self.name=name
        self.books = []

    _q_index=TemplateMethod('/users/chriseb/www/photo/exp/person.html')

bill=Person("Bill")
bill.books.append("Test")

And the template person.html to look like:


  
Person
  
My name is name
  
I own the following books:

  

  

  Book name is book
  
  

  



I'll end up with the recurring url problem right here.

I'm not quite sure what you mean, is it that the quixote module will
recursively invoke quixote to get at the value of each path expression?

No worries. I appreciate the time and energy you have spent answering my
questions.
