Hello Zopistas A somewhat related question to Michael's context proposal. I have a simple dtml:    where I want the new property 'name' to be added in the folder where the property flag was found. is there a simple way of doing it? Am I missing the obvious? Have a nice weekend Pavlos

Re: [Zope] Zope in Virtual Host on ISP
by Jeff Bauer 06 Feb '99

06 Feb '99

Hi everyone. I've been exchanging email with Chris and we have been unable to resolve this problem. Essentially he's attempting to run a simple Python script (as preparation to running Zope) on his ISP's system. The ISP already has Python installed in /usr/bin, is running Apache, possibly with PyApache compiled in. The latest attempt was to try and run testcgi.py with a wrapper script (launchpad.cgi) to set the appropriate environment. Is there anything obvious lacking in the scripts shown below? He has tested the code in his own environment space. Regards, Jeff Bauer Rubicon, Inc. --- Text of launchpad.cgi ---- #!/bin/sh PYTHONPATH=/home/c/change/local/lib/python1.5/test:/home/c/change/local/lib /python1.5/plat-linux2:/home/c/change/local/lib/python1.5/lib-tk:/home/c/ch ange/local/lib/python1.5/lib-dynload:/home/c/change/local/lib/python1.5/sit e-packages export PYTHONPATH PATH=/home/c/change/local/bin:/usr/local/bin:/bin:/usr/bin export PATH MYPYTHON=/home/c/change/local/bin/python MYCGIBIN=/virtual/customer/changeling.com/cgi-bin $MYPYTHON $MYCGIBIN/testcgi.cgi ---- Text of testcgi.cgi ---- #!$MYPYTHON print "Content-type: text/html" print print "<pre>" print "Importing os" import os print "Done Importing os" print "Importing sys" import sys print "Done Importing sys" print "<strong>Python %s</strong>" % sys.version for (x,y) in os.environ.items(): print "%s\t%s" % (x, y) print "</pre>" ----

Well, at www.zope.org you can look at the source of the pages. Sometimes I can find some undocumented features...

Couldn't you just name it foo.ztml in the first place? Having a well-known method for obtaining DTML source is something that will be needed for FTP and webdav support anyway, so we can probably support at least a simple download tab for 1.10.0. The actual implementation will probably be a bit different than that in your patch though, as there are some ftp and webdav-specific requirements that we need to meet as well, and the underlying implementation will probably need to change later to accomodate those. I suspect that changing the apparent id of the object won't be a part of this (at least not initially), since this would throw most clients for a loop...

Interesting... Only the first form works though (the list version returns the wrong instance type, as mentioned in the first posting):     results in: <Topic instance at 7850e0> <ResultSet instance at 4eb550> <Topic instance at 7850e0> 1 Thanks!

sync Zope userids with Apache userids?
by Patrick Diamond 05 Feb '99

05 Feb '99

Hi Currently I have an apache server which has an authentication database containing some 50,000+ userids with associated groups. My question is how do I best (in this case quickest) enable Zope, which is connecting thru the apache server, to use these userids. The userids are stored in a mysql DB, using this DB directly would be great but copying it into Zope regularly would be fine. Any ideas? Thanks Patrick Diamond

RE: [Zope] sync Zope userids with Apache userids?
by Patrick Diamond 05 Feb '99

05 Feb '99

Hi again Thank you for the URL to UserDb, it sounds exactly what I was looking for, but I cannot seem to get it to initialize. I have installed it into the proper directory lib/python/Products/UserDb and restarted Zope. UserDb appears as a product under Zope i.e. "Product at /cgi-bin/Zope / Control_Panel / Products / UserDb " but does not appear in the "To add a new item, select an item type and click "Add". " option in folders. Under the products menu entry for UserDb there are only two tabs "Traceback" & "Help", the Traceback tab contains the following -----------Start Here------------------------------------------------------------------------ --- Product at /cgi-bin/Zope / Control_Panel / Products / UserDb UserDb Import Traceback Traceback (innermost last): File "/shared/gsm/pkg/zope/Zope-1.9.0-src/lib/python/OFS/Application.py", line 378, in import_products product=__import__(pname, global_dict, global_dict, silly) ImportError: Bad magic number in /shared/gsm/pkg/zope/Zope-1.9.0-src/lib/python/Products/UserDb/__init__.pyc -----------End Here------------------------------------------------------------------------ --- Any Ideas? (Perhaps other than its a friday afternoon and your not making any sense!)

Confera question, and calling sub documents of a peer folder
by Brad Clements 05 Feb '99

05 Feb '99

Two questions: 1. Will Confera be included in the Zope release at some point in the future? Is it available as a pre-release now? Is there a list of pre-release items available? I noticed the UserDb pre-release and that got me thinking. I really could use Confera 2. My root folder is getting rather jammed full of stuff, so I moved a database lookup and two formatting documents to a sub folder called 'Documents' >From another subfolder 'Airports', I want to "call" Documents.DocumentList DocumentList (a document) does an  to return some data that is formatted by Documents.DocumentFormat. The problem is that, regardless of where DocumentLookup is located (either in Documents folder or in /), the lookup returns false (no entries) when Document.DocumentList() is called from another folder. Specifically, Airports/index_html does this:  And in Documents.DocumentList, I have  ...  Search returned no results  I always get "No results" when loading Airports/index_html, but it does return results if I load Documents/DocumentList from my browser. This happens even if DocumentLookup is located in / Is it possible to "call" documents in peer folders this way? If so, what is the correct syntax?, or is this a bug? ps.  returns the DTML, which makes sense.

Netscape mangles filenames that contain multiple '.' characters. I just downloaded and extracted it fine after fixing the name.
