The inspector decides to give Tom a pop quiz, asking: "What would you do if you realized that two trains were heading towards each other on the same track?" Tom says: "I would switch one train to another track." "What if the lever broke?" asks the inspector. "Then I'd run down to the tracks and use the manual lever down there," answers Tom. "What if that had been struck by lightning?" challenges the inspector. "Then," Tom continued, "I'd run back up here and use the phone to call the next signal box." "What if the phone was busy?" "In that case," Tom argued, "I'd run to the street level and use the public phone near the station." "What if that had been vandalized?" "Oh well," said Tom, "in that case I would run into town and get my Uncle Leo. This puzzled the inspector, so he asked "Why would you do that?" "Because he's never seen a train crash." ----------------------------------------------------------- FREE CD - A FREE CD of 25 cRaZy PhOnE CaLLs - FREE CD HiLaRiOuS PrAnK PhOnE cALLs - Over 60 Minutes Worth!

I shut it down, and then went to remove the file. There was no var/Data.fs.index file there. I have: Data.fs Data.fs.in Data.fs.lock Data.fs.orig (I created this, it's just a copy of Data.fs after installation before I copied over the 2.0.1 install database, probably identical to Data.fs.in) Data.fs.tmp Is it possible that you meant the .tmp file? Please let me know. I'll hold off on gzipping & sending Data.fs until I hear from you. Thanks.

Python.Org Redesign Contest
by webmaster＠python.org 10 Dec '99

10 Dec '99

Hello Zopistas, Wouldn't you love the Python.Org site to use Zope? Don't you think the Python.Org style is getting a bit dated? Here's your chance to change all that. The design of the Python.Org web site <www.python.org> is nearly two years old now, and while functionally it works very well, we're getting bored with it. We've decided that we're hackers, not web site designers so we thought we'd conduct a little contest: here's your chance to design the new Python.Org web site! Our requirements are: - Use the Zope 2.x platform. We're looking for both a Web site design and an application design. - We want the site to be at least as user friendly as the current site is. This means you should try to keep stuff like images to a minimum in order to help download times for people around the world. - The look should be consistent throughout the whole site. - We want it to be easy to delegate content management of parts of the site to "champions" selected from the Python community. A big goal of this whole effort is to make it easier for the rest of the community to share in the upkeep of the site. For that reason, it should be easy for these champions to make changes, upload new pages, etc. - It should be easy to import as much of the existing Python.Org content as possible. - Bonus points if your solution allows us to include a redesigned JPython.Org site as a virtual domain. - Deadline for submission is Monday, February 21, 2000. We'd hoped to select the new design by time of the Python conference, but we've been informed that some useful Zope products won't be available until after the conference. Better better than sooner :) Everything else is up to you. You can use the existing site design as a starting point, or come up with your own ideas. If we select your design, we will of course need the rights to use your design and code, and your permission to modify it as necessary. Your prize will be prominent acknowledgements on the site (i.e. the "fame" part of "fame and fortune" :). Submissions and questions can be directed to design(a)python.org Good luck! -Barry & Guido, et al P.S. A copy of this announcement is also available at http://www.python.org/Redesign.html

I missed your responses
by Daniel G. Rusch 10 Dec '99

10 Dec '99

I know that I have asked this question before and that several people have responded. But for what ever reason I did not receive the responses. If it's not too much to ask could the kind people who responded re-post their responses I'd greatly appreciate it. What is the definition of (or where can I find one): 1. KeyError 2. AttributeError 3. NameError Thanks, DR

Creating a ZClass instance as a method of another ZClass?
by Jeff K. Hoffman 10 Dec '99

10 Dec '99

Hello, everyone. I have just run into an interesting situation regarding ZClasses. Here's a description of my setup (using Zope 2.1.0): o ProductB contains a ZClass called BClass, which inherits from Folder. o BClass implements several DTML Methods. o ProductA contains a ZClass called AClass, which inherits from Folder. o AClass implements several DTML Methods, and needs to contain an instance of BClass as a method. Things went fine, until I tried to create the BClass instance in AClass's Methods tab. I get the following error: ----- Traceback (innermost last): File /d.local/zope/lib/python/ZPublisher/Publish.py, line 214, in publish_module File /d.local/zope/lib/python/ZPublisher/Publish.py, line 179, in publish File /d.local/zope/lib/python/Zope/__init__.py, line 202, in zpublisher_exception_hook (Object: RoleManager) File /d.local/zope/lib/python/ZPublisher/Publish.py, line 165, in publish File /d.local/zope/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: BClass_add) File /d.local/zope/lib/python/ZPublisher/Publish.py, line 102, in call_object (Object: BClass_add) File /d.local/zope/lib/python/OFS/DTMLMethod.py, line 145, in __call__ (Object: BClass_add) File /d.local/zope/lib/python/DocumentTemplate/DT_String.py, line 502, in __call__ (Object: BClass_add) File /d.local/zope/lib/python/DocumentTemplate/DT_With.py, line 133, in render (Object: BClass.createInObjectManager(REQUEST['id'], REQUEST)) File /d.local/zope/lib/python/DocumentTemplate/DT_Util.py, line 335, in eval (Object: BClass.createInObjectManager(REQUEST['id'], REQUEST)) (Info: REQUEST) File <string>, line 0, in ? File /d.local/zope/lib/python/ZClasses/ZClass.py, line 454, in createInObjectManager (Object: BClass) AttributeError: (see above) ----- Running this through the debugger, I found that the error occurs when, on line 454 as noted in the traceback, the following line is executed in createInObjectManager: return getattr(folder, id) With the cursor sitting on this line in the debugger, I tried: pdb> p folder[id] <BClass instance at ...> pdb> s # this executes the getattr(folder, id) line AttributeError: 'binstance' It is obvious that my instance has been created, and installed into the methods instance via _setObject(), so I am baffled as to why folder[id] works but getattr(folder, id) does not. Can anyone shed any light on this, for me? Am I trying to do something that's outside the capabilities of ZClasses, or have I just missed something obvious? Thanks, --Jeff

Multiple selections
by Alexander Limi 10 Dec '99

10 Dec '99

Zopistas, Can anybody give me an example of how to use multiple selections? (the data type, that is). I searched all my Zope docs, and it was only mentioned one place in the Zope quick reference, but no usage examples. Where does it get its possible selections from? And will it be rendered as a multiple selection field? Thanks in advance. Alexander Limi http://mp3.no

RE: [Zope] Zope stability
by Theodore Patrick 10 Dec '99

>> Version Control and Development Option 1 - VERSION OBJECT There is an object called a version that will take existing zope code and copy it into a protected space for development work. You can test a version seamlessly and then roll your changes forward or undo them. It is a handy way to edit a ZOPE site live and not affect operation until development is complete. It is a rather hidden feature and easy to miss. Option 2 - CUT, PASTE AND RENAME You could also just copy your work folder into another folder work on it and them merge the code by simply changing the name of the folders. That would immediately route request to the new root/folder. If you have issues you can easily undo the changes in the control panel. Typically for us work is done progressively on areas of the Zope site, change a form here, change a SQL method there. It tends to make the process easier to just make a copy of the dependent objects and modify and test the code in an temp folder. Option 3 - Production Server - Development Server This model has worked well for us. As you can run Zope on any capable workstation, it makes sense to do large development work in this model an move the projects into a staging area for testing and deployment. Option 4 - Make Backup/Archive/Version of your ZOPE ODB Weekly we make a copy of the ZOPE ODB for backup and archive purposes besides our daily backups. If we ever need old code we have a version that we can put on any development server and retrieve the contents. It is a very convenient way to manage the overall development process. With every dot release of your code make a copy of the ODB. They tend to compress really well and as they are 1 file make things easy. Make sure to compress the ODB before you make a version, It tends to improve the performance of the database and make your code smaller as it eliminates all changes stored in the Database. Hope this helps although there are many different ways to work with Zope these are the most useful for us. Theodore E. Patrick Ishophere.com
