targetFolder = string.join(traverse_subpath, '/') #you will have to play with
this to get the right target folder for your app
aFolder = context.restrictedTraverse(targetFolder)
searchRes = aFolder.Catalog(some search string here)
do something with search results here
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

Re: [Zope] Re: Preserving Context
Yes there is a 'return 0' at the beginning. This code always executes and works just fine, as I've mentioned before, as long as the template is in the root folder of the given Web site. I'm trying to put this template in a root folder that services all the Web sites of the portal, and that's where I'm having trouble. So this is not because of this code. Your script ALWAYS returns '0' and does nothing more. Just try to remove everything after 'return 0' and see if it changes anything or remove 'return 0' and see what happens then. -- Maciej Wisniowski ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

[Zope] Re: Preserving Context
From: Suresh V [EMAIL PROTECTED]
1. Are you using container rather than context in your script?
2. You can pass your context as a mycontext parameter to your script.
I have this line of code in my page template for handling the 404 errors:
div align=center tal:condition=here/hasSearchEngine
I changed it thus:
div align=center tal:condition=here/hasSearchEngine(mycontext)
I tested the following script with mycontext as a passed parameter:
return 0
catalog = ''
try:
catalog = getattr(mycontext, mycontext.superValues('ZCatalog')[0].id)
except:
pass
if catalog:
return 1
This threw an error concerning mycontext.
TIA,
Javier

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.

In your script you could access the catalog as follows:
afolder = context.restrictedTraverse('folderA/folderB/'+someLocalFolder)
# pass 'someLocalFolder' as a parameter
catalog = afolder.Catalog# assuming you have named your ZCatalog
'Catalog'
The problem with this, is that this script is used at the base of a portal
with several different Web sites, therefore, the root folder of each is
different.
And where is mycontext defined? You will need a tal:define=mycontext here
or something.
I added the following:
div align=center
tal:define=mycontext here
tal:condition=here/hasSearchEngine(mycontext)
...but that didn't seem to help any:
Error Type: KeyError
Error Value: 'hasSearchEngine(mycontext)'
Concerning your comment about the except, this script was written by an
employee of mine. I'm now picking up where he left off. I cleaned it up ;)
TIA,
Javier

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
As far as I understand you have script (say it has id 'handle_404_scr') that handles 404 errors in 'root' folder. In this script you have something like: div align=center tal:define=mycontext here tal:condition=here/hasSearchEngine(mycontext) Yes? So how is this script called? I'm not sure what exactly is your case but you may try: div align=center tal:condition=here/hasSearchEngine(here/aq_inner) or just (without passing a parameter): div align=center tal:condition=here/aq_inner/hasSearchEngine() -- Maciej Wisniowski ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
