FYI: Zope Weekly News

Hi all, It's been another busy week in the Zope community. Lot of people announced contributions, and Zope 2 alpha continues to progress. Many folks seem to be using Zope 2.0, but beware, it is still *alpha* software. Probably the biggest news this week is that UserLand (makers of the Frontier commercial web development environment) are taking a big interest in Zope. UserLand's Eric Kidd orchestrated support for Frontier's XML-RPC in Zope. It will be exciting to see how the Zope community and the Frontier community come together. * Brian Lloyd announced that Zope 1.10.3 final was released. This is the current stable release. http://www.zope.org/Download/Releases/Zope-1.10.3/ http://www.zope.org/pipermail/zope/1999-June/005861.html * Jim Fulton announced the release of Zope 2.0.0a3. This release fixes more bugs and introduces XML-RPC support. This release is a source only alpha release. http://www.zope.org/Download/Releases/Zope-2.0.0a3 http://www.zope.org/Download/Releases/Zope-2.0.0a3/CHANGES.txt * Anthony Pfrunder announced his win32 version of Zope 2.0.0a3. http://student.uq.edu.au/~s341625/ http://www.zope.org/pipermail/zope/1999-June/005970.html * Andrew Kuchling announced a new version of mod_pcgi. It actually seems to work now ;-) ftp://starship.python.net/pub/crew/amk/new/ http://www.zope.org/pipermail/zope/1999-June/005868.html * There was some talk this week about Zope performance. Different people offered different benchmark figures. Some people think that Zope is too slow, or requires too much in the way of system resources, while others suggest that benchmarking is inherently subjective and that Zope performs quite well for most purposes. http://www.zope.org/pipermail/zope/1999-June/005793.html http://www.zope.org/pipermail/zope/1999-June/005809.html * Eric Kidd announced that Zope now supports XML-RPC. Eric has been working with Jim Fulton of Digital Creations and Python god Fredrik Lundh to put all the pieces together. The upshot is that Frontier can communicate better with Zope now. It looks like Zope is going to figure prominently in UserLand's Unix strategy. http://www.zope.org/pipermail/zope/1999-June/005831.html http://www.xmlrpc.com/ http://www.zope.org/pipermail/zope/1999-June/005838.html http://www.zope.org/pipermail/zope/1999-June/005854.html http://nirvana.userland.com/news/discuss/discuss/msgReader$7554 http://discuss.userland.com/msgReader$7596 * Michael Bernstein posted a nice summary of where to find Zope apps. http://www.zope.org/pipermail/zope/1999-June/005726.html * Amos Latteier announced a new version of the Z Classes Tutorial. http://www.zope.org/Documentation/Reference/ZClasses http://www.zope.org/pipermail/zope/1999-June/005854.html * Long time Zope user Phillip Eby announced his ZScript DTML extension. He also released the Let tag, another DTML extension which will probably make it into the Zope distribution. http://www.zope.org/pipermail/zope-dev/1999-June/000599.html * There was some discussion of making Zope international. Ideas were proposed, but it appears that making Zope adaptable to many languages is a large task. http://www.zope.org/pipermail/zope-dev/1999-June/000623.html * Scott Robertson announced a new version of LDAP Connect Object for Zope. This Zope extension builds on work done by Anthony Baxter. http://www.zope.org/pipermail/zope-dev/1999-June/000639.html * Jeff Rush announced the availability of RPMs for Zope 1.10.2 http://starship.python.net/crew/jrush/Zope/ -Amos -- Amos Latteier mailto:amos@digicool.com Digital Creations http://www.digicool.com

Pardon my ignorance, but...
by Barry Bookout 23 Jun '99

23 Jun '99

Hello All, I am quite new to zope, but it's great fun! However, I am having trouble figuring out how to do the following: I would like to have a user search my (MySQL) database for a particular record, then return the record values in an editable form. After the user has appropriately edited the record values, pressing submit causes the database record to be updated. The SQL is not the problem, but chaining the forms together so the second receives the values from the first as its defaults is where I am stuck. Can anyone point me in the right direction? TIA.

Re: Example: How I handle Virtual Hosts and mixed static/dynamic serving

Oops, forgot one thing: I also had to edit App/manage_tabs.dtml so that parent-links work correctly. Almost at the end of the file, change the tabs_path_info expression to "tabs_path_info('.', REQUEST.environ['SCRIPT_URL'])". It's not perfect, but it's an acceptable compromise for me.

Handling lists in requests?
by Thomas Weiner 23 Jun '99

23 Jun '99

Hi, is there a way to handle lists in requests properly? For Example: I have a form getting a list containing a few 'inner' lists from an external method 'ldif' (maybe that's already ugly). I want to give this list-construct via a request to an action form. <FORM action="show_it" method="post">  <input type = "hidden" name="adr_list" value="">  doing some stuff  The  action works fine, but when trying the same  in 'show_it' I receive an Error: Error type: InError Error value: Strings are not allowed as input to the in tag. How should I handle this? thanks Thomas -- fon: ++49 (0)40 42878 3781 fax: ++49 (0)40 42878 2728

nav trees
by Daniel M. Drucker 23 Jun '99

I'm using a tree tag for a navagation system which you can see at http://www.3e.org/elena/ . The problem I'm having is that if you click on the title of a folder (instead of on the +/- like you're supposed to), you end up with another copy of the site nested in the target frame. How would I make it so the folder names would *not* be links? Daniel Drucker

You can use the absolute_url() method to get an absolute URL to use for the link. Iirc the #tree tag also gives you an (undocumented, last time I checked) attribute called tree-item-url which you can access like so:  <a href=""></a>  How would unlinking the folder names solve your problem?

I guess I'm confused as to the "accepted" way to get virtual hosts running under Zope, if such a thing even exists. I have two domains that I would like to use Zope with. A company I work for would like to host many domains with Zope. As far as I see, there would be two approaches to this on the Zope side: 1. Redirecting different parts of the URI namespace to different parts of Zope's internal database 2. Redirecting different parts of the URI namespace to different Zope processes. I can see where (1) would be beneficial for different virtual domains that need to access much of the same information, and where (2) would be beneficial for modularizing sites into independent units. I've looked in the archives, and looked at postings here, and really wonder whether the question I'm thinking about is the one answered by people posting various Rewrite rules here. Of course there is the parallel issue of which web server to use to redirect the URI namespace. I have Apache, and I'm interested in ZServer in the alpha version, but I understand that that is unsupported. However, for the sake of conversation and understanding, can the ZServer in the alpha distribution accomplish the same role as Apache, in redirecting different virtual domains to seperate Zope processes or seperate trees of the Z object database? Assuming that ZServer and Apache do or would eventually support this mode of operation, would ZServer offer better resource usage through its multithreaded nature?

ZServer definatly isn't unsuported, but it is beta, which means you may run into bugs. We would love to hear about any bugs you run into. Now, in the case that ZServer doesn't impliment a feature you want, that would have to be submitted as a feature request to the Collector for consideration to be included in the next or subsequent releases. Note that although ZServer is beta, Zope 2.0 is *alpha*. > However, > for the sake of conversation and understanding, can the ZServer in the > alpha distribution accomplish the same role as Apache, in redirecting > different virtual domains to seperate Zope processes or > seperate trees of > the Z object database? > ZServer doesn't have nearly the configurability of Apache. The short answer is no, although I bet a good python programmer could hack up a quick solution to their specific problem rather well. > Assuming that ZServer and Apache do or would eventually > support this mode > of operation, would ZServer offer better resource usage through its > multithreaded nature? The jury is still out on that questions. Zope 2.0 appears to be definatly much faster than 1.x w/ ZServer, but substantive analysis has not been done with Andrew's new mod_pcgi apache module. I suspect that ZServer and Apache+mod_pcgi will similarly. What ZServer buys you is the ability to do webdav (which Apache can also do, if you patch it) and especialy FTP and XML-RPC (protocols Apache can't, and never will speak). Note however, that Apache can work *with* ZServer using pcgi, so Apache+mod_pcgi+ZServer will get you all the benefits: Apache's configurability as a webserver, mod_pcgi and ZServer's speed, webdav, FTP, and XML-RPC support. -Michel > > > > _______________________________________________ > Zope maillist - Zope(a)zope.org > http://www.zope.org/mailman/listinfo/zope > > (For developer-specific issues, use the companion list, > zope-dev(a)zope.org - http://www.zope.org/mailman/listinfo/zope-dev ) >
