I think dtml methods expect to receive a client as the first (non-self) arg
and the namespace as the second.  But that raises the question of where
you get the namespace from in a python method so you can pass it...

A 'call of nonfunction' type error, as far as thing to render is index_html
(DTMLMethod).

Anyway, I have tryied to do it in a whole lot of ways, when all I want to do is
to copy the behavier of . Shouldn't be too hard,
I thought.
But I have no access to that function. Calling self.thing returns None, calling
self.aq_parent.thing returns an html_quoted version of the doument_src. The
real problem, come to think of it, is that if I call
self.aq_parent.thing.__call__() I get the thing, but with a key error for the
standard_html_header. So, I don't have access to the namespace? or the
aquisition engine doesn't work this way?

It's just too dinamic...I mean, we have an index_html on the root wich serves
everything and everyone. Then we have thematic areas with top and bottom bars
wich differ from each other, than there's the real info being queried wich
appears in the middle "frame", but all this without frames, with only a base
table structure on the root index_html.
Btw, data can change very rapidly, and so the cache was not to avoid charging
zope with the request load, but to avoid having to process the pages, wich are
rather complicated, everytime it gets requested. And we are getting 1000+ hits
per minute, so a one minute cache with a pre-rendered page for us would do
fine. We try to avoid external help on this.

We all had experience in developing with Apache/Perl or Apache/PHP3 and ok, it
works, it's fast and all that. But seriously, developing a portal without zope
just seems impossible now, knowing that what took me 1-2 weeks to develope
before can now be done in a days work, and all without mixing functional code
and aspect. Wow, we can even undo! Can't beat this, I'm afraid. :)

RE: [Zope-dev] Calling rendered objects from a product

More than one way to skin that particular cat I'll warrant.

here's one cut from a heavily used external method to render a zope
dynamic page to a disk file.

import Globals
...
o = getattr(self,thingtorender)
rendered_doc = o(client=o,REQUEST=REQUEST,globals=globals())
...

Incidentally, why bother making a cache inside of zope? There are
perfectly good ones already available out there like squid. Wouldn't it
be easier to just dump the result from every query you encounter into a
disk file. 

Serve with apache but run a squid cache front end to zope. This would be
relatively easy to develop and could probably run very fast.

Refresh the static files as often as needed. How often do things change
in the data? 

If slowly, hourly re-rendering of queries as they arrive might work ok.

Given that there are tools to do this, it just might be easier with
static html than with live zope
