RE: [Zope] Netscape Image Problems (LoginManager?)
by john＠nurl.net 24 May '00

Well I have determined that it has nothing to do with PTK or Login Manager, well I think anyway....... If you hit reload it breaks the images on the root level, if you put your cursor in the Location, or URL field and hit enter it reloads fine. I truly don't understand this problem and it only does it with images, in Netscape, is this an issue that everyone is just accepting or is there a fix for it. j At 08:51 AM 5/22/00 -0500, you wrote: > >I'm not using PTK, but I am using LoginManager.

Subclassing from Custom Python Classes
by Pete Kazmier 24 May '00

24 May '00

I need some guidance or pointers to more information. My Zope journey began last Thursday and I've been glued to zope.org ever since. I'm trying to understand the following paragraph from the Zope Developer's Guide from the section on "Subclassing from Custom Python Classes": >> You should also note that your subclass must obey the ZODB >> persistence rules, which basically state that mutable sub-objects >> should be treated immutably. For example, >> >> self.bird='parrot' # OK >> self.map['bird']='parrot' # NOT OK, will not trigger persistence >> machinery >> m=self.map >> m['bird']='parrot' >> self.map=m # OK, treats a mutable object immutably What are these "persistence rules" and how come the second example is ok? I thought in Python, when you assign "m = self.map" that m is simply pointing to the same object as self.map and that any changes to m affect self.map too? Does the "self.map = m" have any effect? Don't they point to the same object? I ask because I've already built my first product based on a custom python class I wrote (its a router object that has methods to query various snmp oids) based on a ZClass and I want to make sure that I am not doing anything wrong. In addition to the methods that query the oids, I store the results in an instance variable of my Python class so I can cache the information for a specified amount of time. Is this safe to do? Can I store these values in my Python instance (self.xxxx), not a ZClass property? Also, What happens if multiple people activate my query method, do I need to worry about them stomping over each other as the method writes the results to the instance variables? Is there any record locking of objects? Lastly, since I couldn't really find any pointers regarding a builtin Zope scheduler that is bug free, I need to write a small python script that I can place in a cron job to run every ten minutes to call the query methods of these objects so they update their cache instances. Is there a link on how to get a regular Python script access to the ZODB? Thanks in advance!! Zope is great!!

Building ZPatterns
by Oliver Maunder 24 May '00

24 May '00

I'm trying to install ZPatterns 0.3.0 on an NT system and I've come across problems building the dynpersist C extension. Basically, I need the compile.py script to build a Visual C++ project to compile the extension, but the download site for compile.py is down, and I can't find a copy anywhere else. So... does anyone fancy sending me a copy of either compile.py, or a copy of the dynaccess extension precompiled for Win32? Thanks for your help Olly

RE: [Zope] newbie question: case sensitive folder problem
by Marcus Collins 24 May '00

24 May '00

You could try using Apache rewrite rules to convert all URL's to lower case, and then use only lower case names for your folders, documents and methods. As long as the case is consistent, one rewrite rule should cover everything. hth, -- Marcus > -----Original Message----- > From: Alexander N Gould [mailto:agould@student.umass.edu] > Sent: 24 May 2000 13:43 > To: zope(a)zope.org > Subject: [Zope] newbie question: case sensitive folder problem > > > How can I make a folder on my site case - insensitive in > regards to access > from URLs.

newbie question: case sensitive folder problem
by Alexander N Gould 24 May '00

24 May '00

How can I make a folder on my site case - insensitive in regards to access from URLs. If someone types http://mysite.com/bigfolder/ into their browser, I want it to take them to the Bigfolder, but right now, it produces a missing object error. Any hints? Sorry if this is a silly question - I'm just getting started here. I use zope with pcgi on Apache. -------------- Building highways to reduce traffic is like loosening your belt to reduce obesity
