by Martin Koekenberg 04 May '06

04 May '06

Hello, Is it possible to use a DTML-In to display all DTML Documents in a folder exept the one's with a centain value in a property ? Example. DTML Document one with property a=bc DTML Document two with property a=de DTML Document three with property a=bc Now I want to use DTML-IN to display all the dtml documents except the ones with property a=de. I also use the size and batchsize property to create links to the next 10 documents..... If I use an if statement the next 10 can be 9 ore less 9 items because there could be one ore more documents with a=de. Who can help me ? regards, Martin Koekenberg

Problem with ExtFile
by Bruno Grampa 05 Apr '06

05 Apr '06

Hello, i've a problem with ExtFile 1.4.4 installed in a Zope 2.8.6 (on RHES4). The redirection, at the end of file creation doesn't work. To test the problem you have to create these methods: The first one is called 'form': --- <dtml-var standard_html_header> <form action="write" method="post" enctype="multipart/form-data" name="form1"> <p> Insert <p> Id <input type="text" name="id"><br> <b>File</b><input type="file" name="file" value=""> <br> <input type="submit" value="Send"> </form> <dtml-var standard_html_footer> --- The second one is called 'write': --- <dtml-comment> <dtml-call manage_addProduct['ExtFile'].manage_addExtFile(id=REQUEST['id'],title='',descr='',file=REQUEST['file'],content_type='', permission_check=0)"> </dtml-comment> <dtml-call "manage_addProduct['ExtFile'].manage_addExtImage(id=REQUEST['id'],title='',descr='',file=REQUEST['file'],content_type='',create_prev=1, maxx='100', maxy='100', ratio=1, permission_check=0)"> <dtml-var standard_html_header> Ok, done. <dtml-var standard_html_footer> --- If i use manage_addExtImage i got the "Ok, done" message; if i use manage_addExtFile no, just a piece of page (junk?). I can't understand why, can someone help me? Thanks! Bruno

Zope and Tomcat troubles
by Mads Munch Hansen 04 Apr '06

04 Apr '06

Hi, Since I installed Zope on my server Tomcat has stoped working, and I was wondering if any of you knew of a solution. When I try to load the management interface for TomCat, all I get is a blank page, the same when I try to log into OpenXchange... I installed zope from the Plone Suse 10 rpm bundle on a Suse 10 box. I hope this isn't too much off topic, but I'm quite sure Zope related. Thanks in advance, Mads Munch Hansen

Question about Zope and security
by Cyrille Bonnet 03 Apr '06

03 Apr '06

Hi there, I have been telling all my clients about how great Zope is for security: fine-grained permissions, security framework, roles, etc. Now, one of my clients has a security expert who took a close look at how Zope authenticates users. The results were not good. The main problem is that Zope stores the username and password in a cookie in clear text (base64 encoded). Even though it only happens in their internal network, my client wasn't too happy, because it makes them vulnerable to a man-in-the-middle attack. I know, the odds of that happening are low, but storing the username and password in clear text is clearly not best practice. So, my question is: is there a way to secure Zope authentication? I did find Dieter Mauer's DigestAuth product: http://www.dieter.handshake.de/pyprojects/zope/#DigestAuth It looks good. I have used other produts from Dieter before and was very pleased with the quality of his code. Now, have other people used it? Does it work with WebDAV? How secure is it (I am no security/encryption expert)? Also, if it is good, why is not part of default Zope?? Finally, a little side story: you know how in Windows XP, you can connect a drive to a WebDAV server? Well, if you install Service Pack 2, you can't use that feature to connect to Zope anymore. Interestingly enough, it seems that it is precisely because of that authentication vlunerability: Win XP SP2 refuses to connect to a WebDAV that doesn't at least encode the username/password in Digest authentication... Any comment or pointers are very welcome. Cyrille

Debugging Zope on Windows
by kjzz.webmaster＠riomail.maricopa.edu 03 Apr '06

03 Apr '06

I am using Zope 2.5.0 (binary release, python 2.1, win32-x86), and the python 2.1.3 distribution of from python.org as a service on a Windows 2000 server. I have heard that there is a way to debug zope and save error messages to a text file using the "STUPID_LOG_FILE" parameter however I'm not clear on how to implement this. I have tried adding the the paramter, STUPID_LOG_FILE=Zope.log to the Z2.py file. I modified the command line parameters "C:\Python21\python.exe" "C:\PROGRA~1\Zope\z2.py" -S for the registry value at: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Zope\Parameters\start to "C:\Python21\python.exe" "C:\PROGRA~1\Zope\z2.py" -S -D STUPID_LOG_FILE=Zope.log or should this be "C:\Python21\python.exe" "C:\PROGRA~1\Zope\z2.py" -S -D EVENT_LOG_FILE=Zope.log ??? Still, when I restart Zope, I'm not seeing the log file. Does anyone know how I might set this up properly on a Windows Machine? Alternatively, has anyone configured the z2.py file (or windows registry) to use a syslog utility (such as the Kwiki Syslog Daemon), found here: http://www.kiwisyslog.com/info_syslog.htm Sincerely, John T.

logging from external methods
by Jed Parsons 02 Apr '06

02 Apr '06

I'm trying to perform some logging from external methods. I've discovered that, if you're not careful, you get more and more loggers each time Zope reloads the module. This leads to an ever-increasing number of identical entries in the log file, whose timestamps all match down to the millisecond. Currently, thanks to the helpful folks on python-list, I've got it down to two entries per time. My goal is to get exactly one log entry per event logged :) Here's the code I'm using in an external module. I set up a global _logger instance that various methods in the module use: import logging _logger = logging.getLogger("lois.access") _logger.setLevel(logging.DEBUG) if not _logger.handlers: _handler = logging.FileHandler(os.path.join(LOG_ROOT, 'access.log')) _formatter = logging.Formatter("%(asctime)s %(name)s %(levelname)s: %(message)s") _handler.setFormatter(_formatter) _logger.addHandler(_handler) _logger.propagate = 0 Each time a method calls _logger.info("some event"), I get duplicate entries, like so: 2006-03-31 15:07:57,676 lois.access INFO: get wiki_ldap 0.html (jedp) 2006-03-31 15:07:57,676 lois.access INFO: get wiki_ldap 0.html (jedp) The _logger.handlers test is there to make sure I don't spawn a new handler each time the module gets reloaded. This makes a huge difference; without it, the number of duplicates grows and grows. Can anyone tell me how to get a logger to leave just one log entry from an external module? Many thanks.

Strange behavior with TAL and python: expressions
by Floyd May 01 Apr '06

01 Apr '06

Great and mighty Zope gurus, I have a template which calls a macro. Within the template, I tal:define a variable, 'form'. Within the macro, the 'form' variable (which is an FSForm object) is defined as None unless I access it using python expressions. If I attempt to do anything with attributes of 'form', I get an AttributeError indicating that the NoneType object, form, doesn't have the attribute that I'm looking for. However, I can use 'form' any way I want inside the template that calls the macro. It seems that the macro call somehow lost part of the information associated with the 'form' variable. I worked around the problem by defining form using a python expression instead of a pure TALES expression. I was also able to work around the issue by accessing 'form' within the macro using python expressions instead of TALES. Why would this happen? Is this expected? I'm using Zope 2.7.5 and Formulator 1.9. I'm not sure what other products to list here; this seems like a ZPT-related thing. Please let me know if there is any more information I can provide. Thanks! -- Floyd May Senior Systems Analyst CTLN - CareerTech Learning Network fmay(a)okcareertech.org

Dependent List
by BKJ＠telefonica.net 01 Apr '06

01 Apr '06

Hello, I have a problem with my archetype, I'm using dependent lists. I've downloaded the MasterSelectWidget product, but I have a problem with it. In my archetype I have a master field and a slave one, I install the archetype, I add an object of this type to my portal, but when I load the saved object and try to edit it, I see that the slave field (a selection widget) don't have the value that I have selected. How can I solve it? Is there any alternative to MasterSelect widget? Thanks ! TERRA -->
