July 1999 - Zope-Dev

Temporary hold on public CVS updates
by Ken Manheimer 20 Jul '99

20 Jul '99

We will be having a hold on updates to the Zope public CVS repository, in anticipation of the Zope2 beta release thursday. (I didn't say *which* thursday, you'll have to guess:-) (Well, this thursday - but you didn't hear it here.) When we resume updates, there will be a new (and simple) Zope2 module, which will have the ongoing updates. The old Zope module will not be updated, and eventually will be retired - we're taking the opportunity to purge some accumulated cruft from the organization of our repository. I'll post further details when the time comes. Questions? Comments? Lemme know. Ken Manheimer klm(a)digicool.com

It is possible to edit the user folder code, or to create a ZClass which subclasses it to modify the type of object returned by validate(). IMAPAdapter does this, it's validate() method actually works with a low level connection manager to return a User object which defines a whole IMAP API and a connection logic (including connection caching and automatic connection reconstruction). Thus, IMAP operations happen from the perspective of AUTHENTICATED_USER, like so: <dtml-var standard_html_header> <dtml-with AUTHENTICATED_USER> <dtml-tree expr="imapFolderTree(REQUEST)" sort=id nowrap=1> <img src=<!--#var icon>> <dtml-var shortname> <dtml-if num> (<dtml-var num>) </dtml-if> </dtml-tree> </dtml-with> <dtml-var standard_html_footer> imapFolderTree() is a method of the User object. http://www.zope.org/Download/Contrib/IMAPAdapter-0.1.0-nonbin.tgz -Michel > This would be useful for user preferences, etc... > > thanks, > -jeff > > > _______________________________________________ > Zope-Dev maillist - Zope-Dev(a)zope.org > http://www.zope.org/mailman/listinfo/zope-dev > > (For non-developer, user-level issues, use the companion list, > zope(a)zope.org, http://www.zope.org/mailman/listinfo/zope ) >

UserFolder based on an RDBMS?
by Jeffrey A. Marshall 20 Jul '99

20 Jul '99

Hello, We're trying to convert a large site over to Zope which makes some heavy use of information stored in an RDBMS and wondered if anyone has done any work extending the BasicUserFolder/BasicUser classes so that they get their information from an RDBMS instead of Bobo? How about any pointers to code which can be used as a starting point? Another question we had was if it would be possible to extend acquisition to include properties/methods defined for the currently authenticated user? This would be useful for user preferences, etc... thanks, -jeff

Zope 2.0.0a4. ZODB3 questions.
by Andreas Kostyrka 20 Jul '99

20 Jul '99

Hi! Some questions: -) Is ZODB3 really usuable with 2.0.0a4? I don't mean production quality, but good enough for developement quality, meaning that one can develop already websites with it. -) What is the API for multithreaded db access: Is SomeFolder.attr=PersistentObject() enough, or are there some trapdoors hidden? -) What about the DAs?

Zclass questions
by Anthony Pfrunder 19 Jul '99

19 Jul '99

[I'm re-sending this as it appears to have got lost somewhere in the matrix...] [I'm posting this here b4 the Collector in case these have been solved in CVS versions. NB I'm using Zope A4 on IE 4 for Windows] Hi, I've found a bug(s) in ZClasses. Try the following: Create a new product Create a Zclass in the Product Delete the Zclass you just made Create a new Zclass in the same place. You will get a traceback error complaining about missing method manage_addzclass. Press the reload button and try again and it works Also, If you make anything items in a Zclass methods folder apart from a DTML Method Zope will throw up random errors. Sometimes it will put it into the root of the zclass (along with the factory DTML docs), sometimes it will insert it and then throw up intermittant tracebacks relating to missing zclass methods. To fix it, delete the zclass and add it again. Finally, If I make a zclass based on DTML Document and then create an instance of it and then VIEW the instance then IE downloads the document instead of displaying it. NB I was using a metatype of "Visual DTML". I haven't have a chance to try it with netscape yet. A few Q's about ZClasses (things I am going to try but want to ask while I'm posting;): If I make some methods in a Zclass can then call them via: Instance_html/mymethod? (where Instance_html is the url of a DTML Document based zclass) Which way does the acquision ('cuse the spelling) work? Through the Instance or through the zclass or both? If I make a zclass in the methods part of a zclass can I inherit the methods of the parent? Can I pinch the tar.py for my Zope for Windows distrib? ;) Cheers, Anthony Pfrunder

Think of it as midway between an expr and an External Method, erring on the side of the expr, as far as what was available. Gee, security, power, and simplicity go so well together. :^) --Paul

Introspection, managing External Methods?
by Robin Becker 19 Jul '99

19 Jul '99

Are there any plans to upgrade the External Methods product to allow remote management ie creation/deletion/modification of the file texts? I ask because a major advantage of Zope is the ability to manage at a distance and this is not possible for External Methods. I can see easy fudges using a hack of fsimport, but something based on the existing external methods would be better. More generally how can one upgrade a Zope product remotely; assuming this were possible it would be nice to be able to remotely shut down Zope and get it to restart. -- Robin Becker

Folders without Properties?
by Bill Anderson 18 Jul '99

18 Jul '99

Updated my cvs dump last night, and while playing around with it, I noticed that folders don't seem to have a properties page anymore. Does anyone else have this problem, or did I miss out on them going away? Bill
