Michel's use of a debug flag is cool. Only, are you aware of Z_DEBUG_MODE (aka BOBO_DEBUG_MODE, aka __bobo_debug_mode__)? It's purpose is exactly things like this. It gives more informative errors, and should make all objects that care operate in debug mode. For example, I believe that HTMLFiles should check for this and reload it's content if it is set. Check out this snippet of code from Main.py for n in 'Z', 'BOBO': if os.environ.has_key('%s_DEBUG_MODE' % n): n=string.lower(os.environ['%s_DEBUG_MODE' % n]) if n=='no' or n=='off': continue try: n=string.atoi(n) except: pass if n: Globals.DevelopmentMode=1 Now you know how to check for debug mode in your own objects, check for 'DevelopmentMode' -Amos

How does my Folder Product load default documents? Create a list of tuples containing filenames (without '.dtml') and title pairs: self.defaultDocs = [ ('index', 'NotMail'), ('address', 'Address Book'), ('attach', 'Attach a File'), ('composer', 'Compose a Message'), ('contact', 'Contact Developers'), ('search', 'Search Your Mailboxes'), ('results', 'Your Search Results'), ('folder', 'Mailbox'), ('message', 'Message'), ('help', 'Help'), ('lookup', 'Lookup Users'), ('standard_footer', 'Standard HTML Footer'), ('standard_header', 'Standard HTML Header'), ('noto', 'Message must have at least one recipient.'), ('reminders', 'Your Reminders'), ('save', 'Save Message'), ('logout', 'You have been logged out'), ('GPL', 'The GNU General Public License'), ('sentmail', 'Mail was sent')] # Then iterate over them and create each one for id,title in self.defaultDocs: try: self.defaultDocFile(id, title, id) except: pass # defaultDocFile is a handy little function: def defaultDocFile(self, id, title, file): f=open('%s/Products/NotMail/%s.dtml' % (SOFTWARE_HOME, file)) file=f.read() f.close() self.manage_addDocument(id, title, file) When your debugging your DTML, it's a pain to keep deleting and creating new instances of your object in order to load the new dtml files off of the disk. This function comes in handy: def refresh_docs(self, REQUEST): """ refresh documents from disk (for debug purposes) """ for id,title in self.defaultDocs: try: self._delObject(id) except: pass try: self.defaultDocFile(id, title, id) except: pass return self.manage_main(self, REQUEST) Then, assuming your object has an attribute 'debug' you can define some DTML like so in your manage_main screen:  <p><a href="refresh_docs">Refresh Documents from disk</a></p>

bug: ZOPE FAQ product failing on starship.python.net
by Joe Van Andel 04 Mar '99

04 Mar '99

I'm trying to use the FAQ module to build a FAQ area for Numeric Python. starship.python.net is running Zope-1.10.2 . I've simply created a few categories and sample FAQs, for testing. The last thing I did was to create a 'faqmaster' user, so I could let NumPy email list subscribers add/edit FAQ entries. But now, the FAQ module seems broken (see below for details) Any ideas on how to fix this? Right now, the URL http://starship.python.net:9673/crew/vanandel/NumPy/ yields "System Unavailable", with a backtrace of: Error type: Error value: isCategory traceback (innermost last): File /home/zope/Zope-1.10.2-src/lib/python/ZPublisher/Publish.py, line 877, in publish_module File /home/zope/Zope-1.10.2-src/lib/python/ZPublisher/Publish.py, line 590, in publish (Info: crew/vanandel/NumPy/) File /home/zope/Zope-1.10.2-src/lib/python/OFS/DTMLMethod.py, line 155, in __call__ (Object: index_html) File /home/zope/Zope-1.10.2-src/lib/python/OFS/DTMLMethod.py, line 151, in __call__ (Object: index_html) File /home/zope/Zope-1.10.2-src/lib/python/DocumentTemplate/DT_String.py, line 513, in __call__ (Object: index_html) File /home/zope/Zope-1.10.2-src/lib/python/TreeDisplay/TreeTag.py, line 154, in render (Object: a tree tag) File /home/zope/Zope-1.10.2-src/lib/python/TreeDisplay/TreeTag.py, line 244, in tpRender (Object: Navigation) File /home/zope/Zope-1.10.2-src/lib/python/TreeDisplay/TreeTag.py, line 331, in tpRenderTABLE (Object: Navigation) AttributeError: (see above) Joe VanAndel Internet: vanandel(a)ucar.edu National Center for http://www.atd.ucar.edu/~vanandel/home.html Atmospheric Research

etcUserFolder Product
by Michel Pelletier 03 Mar '99

03 Mar '99

Greetings, (This is crossposted because it is a product anouncement, and contains interesting developer pointers) I've have massaged the source code for UserDb and created a new user folder products called etcUserFolder. This products authenticates off of a flat file of usernames:cryptedpasswords. If there is anything trailing the crypted password it is ignored, so any /etc/passwd file will work. It is generaly not recommended, however, to use your /etc/passwd file for security reasons. This is an unsuported product and has been written because it was asked for a few times, and I felt the community could use another good example of writing user folders. It also shows off cookie authentication which Brian perfected with UserDb. Here is the documentation: etcUserFolder requires a directory called 'etcUsers' in which to place your file containing the uid:pwd pairs. This directory may be an INSTANCE_HOME (typicaly your top level Zope dir), SOFTWARE_HOME (typicaly 'lib/python') or in the etcUserFolder directory. Jim wrote a nifty function called getPath that sniffs all of these places for a directory and file of your choosing. This function is included in etcUserFolder and will be included as a standard function of the next release. Other Product authors may find it interesting. Since the flat file is meant to be b/w compatable with /etc/passwd and htpasswd style files, there is no Role associated with the users it authenticates. You can specify a default role which is, by default, 'etcUser'. I have not done extensive testing of this, therefore it is a pre-release. Please send bug-reports and hopefully a patch to me (michel(a)digicool.com) http://www.zope.org/Download/Prereleases/etcUserFolder/etcUserFolder.tar .gz -Michel

Doh. I was hoping to keep it down to one glaring mistake, but instead there are at least four - the URL's i specified were wrong, i should have put www.zope.org instead of www.digicool.com! The correct URLs (tested, this time:-) are: zope http://www.zope.org/mailman/listinfo/zope http://www.zope.org/mailman/roster/zope zope-dev http://www.zope.org/mailman/listinfo/zope-dev http://www.zope.org/mailman/roster/zope-dev Ken again. klm(a)digicool.com

zope-dev created
by klm＠digicool.com 03 Mar '99

03 Mar '99

As threatened, i've created the zope-dev list, and through a bit of finagling, you're on it. I've duplicated the membership data for the zope list, so that each of you will have the same password, user options, digest status, etc, as on the zope list. It's now up to you to choose whether to keep both memberships, or resign from one or the other list. And to start posting zope-developer-specific messages to the zope-dev list, instead of the general zope list. Ideally, the traffic from both lists, together, will equal what was being carried by the single consolidated list, so traffic from both, together, will be no more massive than the consolidated traffic was. The idea is to _partition_ the traffic from the consolidate zope list, so cross-posting is strongly discouraged. In response to my proposal some people suggested more elaborate schemes for dividing, but i don't currently plan to do that. This does not mean that there won't be special-interest lists created - things like the zope documentation project that martijn faassen is seeding are prime candidates. However, for more wide-focus lists like zope and zope-dev, it can be hard enough to avoid confusion about what types of messages should go where - i think it's really important that the division be fairly simple and straightforward. Thus we're starting with zope and zope-dev, and will only split further if/when heavy traffic with clear divisions appears. In that light, let me try to clarify the division between the zope and the zope-dev list. The key concept is that there is some significant portion of the zope user community that just want to use zope to publish their web content, and would be perfectly happy to not know the nitty gritty of _how_ zope does it. So if you have a question or neat trick about running zope or publishing content, or you know of some resource or public venue for zope that would interest zope community, it probably belongs on the general zope list. However, if you want to talk about zope's guts in all it's gory detail, send your message to zope-dev. I expect this will take some shaking out, with time. However, i see that i mistimed my prior test, so you all are already aware of the new list's existence - i'm going to send this, and let ensuing discussion clarify as needs be. Feel free to contact me directly if you have questions or need help with your subscriptions - but note that much can be done from the respective lists listinfo and roster pages, which i'll itemize below. (For instance, you can find your subscription options page by going to the respective roster page an clicking on your subscription address, and from there unsubscribe or change your subscription options...)

How can I put Zope on a cdrom to be used in multiple platform environment? Since python is cross-platform it seems possible, however, how could I manage that? Rgs, Kent Sin
