This is the repr() of the object.

It works, it's just not what you really meant to ask for :-).

<span tal:replace=3D"structure python:container[page]()">body</span>

I think it would be clearer if you made index_html a Python Script
instead.  It's what I'm doing with a site whose index needs to be
dynamically created based on who the user is and the contents of some
SQL dbs.


# Script(Python)

page REQUEST.get( 'page' , None ) :
if not page :
    page =3D 'content_1'

print container[page].title
print container[page]()

return printed
