I'll respond to my own post here by saying I'm messed in the head. I was looking at two different versions of manage_tabs.dtml, one from a slightly newer checkout :-) No mystery here... --Brian On Fri, 18 Feb 2000 11:25:12 +0900 Brian Takashi Hooper <brian@garage.co.jp> wrote:
Here's a question for any Document Template experts out there:
What is the mechanism which determines whether REQUEST is sent to a function evaluated using dtml-var?
Recently I have been skulking around the management screen templates, and I noticed that somehow it is possible to write something like:
(in manage_tabs.dtml)
<dtml-var "HelpSys.button(HelpSys, product=option['help'][0], topic=option['help'][1])">
Here the 'button.dtml' HTMLFile object is being called with 'HelpSys' (the Help System instance) as a client and two keyword arguments, 'product' and 'topic'. That seems pretty clear.
However, in helpURL, which is a subtemplate of the button template, looks like:
<dtml-var SCRIPT_NAME>/Control_Panel/Products/<dtml-var product>/Help/<dtml-var topic>
SCRIPT_NAME is part of the REQUEST namespace, as far as I can tell... but how is the REQUEST being passed to helpURL?
I added some debugging output to App/special_dtml.py to visualize HTMLFile as it's being called, and sure enough it is getting passed a REQUEST.
What's going on here? When I do stuff similar to the above in an expr, I always seem to have to explicitly pass along the namespace, a la:
<dtml-var "myMethod(REQUEST=_)">
Enlightenment Please!
