First of all, thank you very much for your help.
I'm confused. I had a programmer working for me that wrote the following code:
return 0
catalog = ''
try:
catalog = getattr(context, context.superValues('ZCatalog')[0].id)
except AttributeError:
pass
if catalog:
return 1
Now, that works just fine if I leave the page template that calls it in the
folder of a specific Web site. But when I put that template in a "root" folder
that all the Web sites of the portal can call, it only gives me a printout of
the tree of what's in the root folder. What I'm trying to accomplish is that it
gives me the tree of the specific Web site folder from which it is called.
My problem is that I frankly don't understand what my programmer wrote...how it
works. Research taught me that "superValues" returns the meta_data of ZCatalog,
we're popping the first element of the tuple, getting it's ID, all in context
of the call, and calling that a catalog. But why do we return "1" if we get a
catalog? How does that print the catalog? Then, how do I incorporate your
information to achieve my goal?
Thanks for any help you care to offer,
Javier

None of that worked :( The latter gave me the same as without passing
"aq_inner", while the former threw errors based on syntax.

Re: [Zope] Re: Preserving Context
The script routine doesn't have to be located in root. traverse_subpath is populated using the names of all subfolders that occur after the script file name in the URL. So if your URL is: http:/my.web.site/folderA/scriptA/folderB/folderC, then scriptA will receive a traverse_subpath variable (in REQUEST namespace) that contains ['folderB', 'folderC']. Note: this will not work if there are any other scripts, DMTL methods etc in the URL after 'scriptA'.

Re: [Zope] Re: Preserving Context
traverse_subpath works for me just fine. if you placed the 'tst' python script in your root folder (and this script contains the line "return str(traverse_subpath)" ) you should get: http:/your.web.site/tst -> should return an empty list [] http:/your.web.site/tst/folderA -> should return: ['folderA'] http:/your.web.site/tst/folderB/folderC-> should return ['folderB', 'folderC'] What version of zope are you running?

Re: [Zope] Re: Preserving Context
In your root folder you could have a script that accesses the ZCatalog which
can be called from any subfolder and can tell where it was called from... try
the following: create a python script (tst) in your root folder that contains
the following code:
return str(traverse_subpath)
then invoke this script file as followings:
http:/your.web.site/tst
http:/your.web.site/tst/folderA
http:/your.web.site/tst/folderB/folderC
(substitute your own subfolders as required)
This may get you what you are looking for.
Alternatively, if you need more control over the parameters that are getting
sent to the script file in the root folder, then you could create a script file
in each subfolder which calls the 'root script' with the necessary 'localized'
parameters.
