As the author of a ZPublisher patch for this problem (possibly the one referenced above), allow me to lay out the problem. Sadly, my patch turns out to be only a partial fix; I'm thinking hard about how to improve it. The problem occurs when a URL such as "http://host.com/C/D" refers to object "A/B/C/D" in the Zope object hierarchy, usually by rewriting in Apache. The "internal" URL constructed by Zope as it traverses the objects necessarily includes "A" and "B", as they are part of the access path. Whenever an "external" URL is produced for client consumption, via URLn in a var tag for example, it should *not* include "A" and "B". My patch simply discards the "internal" URL once object traversal is complete, and replaces it with the contents of SCRIPT_URL. This takes care of URLn and BASEn, but not usage of SCRIPT_NAME+PATH_INFO. Also, passing through a __bobo_traverse__ gives the target object an improper URL. The desired behavior is to simply omit from the constructed URL the first n objects traversed, which ought to be ordinary Folders. I'm considering simply passing the number n to ZPublisher in an environment variable so that it can leave the URL alone until the number is decremented to zero. The only problem I see with this is that there's no valid "external" URL for the first n objects traversed, so access error messages relating to these objects will be munged. I also don't see any way around that. then-again-I-also-didn't-see-the-other-problem-until-too-late-ly y'rs Evan Simpson

It worked! Thanks. Btw, this looks like HOWTO material to me. As for the infinite recursion, I'd already included such a guard in my own SQL code, but I deleted in the quoted code to make it clearer. ;-) -- Alexander Staubo http://www.mop.no/~alex/ "`This must be Thursday,' said Arthur to himself, sinking low over his beer, `I never could get the hang of Thursdays.'" --Douglas Adams, _The Hitchhiker's Guide to the Galaxy_ >-----Original Message----- >From: Phillip J.

Re: Evan Simpson's static/dynamic serving solution and role-based executable business model frameworks...
by Evan Simpson 28 Jun '99

28 Jun '99

I appreciate the kudos and the framework reference. It sounds like we're in somewhat similar situations (managing lots of little sites) and I certainly agree with your points about dynamic serving and webcrawlers. The Zope community still has some thinking to do about how heavily Zoped sites will interact with the rest of the world. You should know, however, that I'm having to rethink my "solution" to the Zope sub-tree serving problem; My footnote about __bobo_traverse__ led right into a snakepit. Any URL leading to a Product method (I think) is liable to pass through __bobo_traverse__. This won't matter too much to me if it only affects management, such as adding new Product instances, as I can just use the full proper URL. It doesn't make for a great general solution though, and I'm nervous about what else may be affected. Also, the "only statics have periods" part of my framework required a bit of Product-munging. Confera, for instance, puts an extension on its internal images.

automating new user folders
by Robert Canary 28 Jun '99

28 Jun '99

Hi, I would like to create a zope folder under the personal folder automagically when I create a new user account on my term server. I also would like to have certain objects (ie standard user page) included in this new folder. What is the best way of going about this? I was thinking I could use a perl script to (with the www.pm) to send a commad to the Zope.cgi, but I don't know how to get past the logon. Can I do something like "url/Zope.cgi/manage?username&password" ? Thanks in advance :-) -- robert canary system services OhioCounty.Net rwcanary(a)ohiocounty.net (270)298-9331 Office (270)298-7449 Fax

Using fmt= with External Method
by Alexander Staubo 28 Jun '99

28 Jun '99

I have not seen any documentation on this, so I'm definitely fumbling in the dark here. Please bear with me. I'm curious if it's possible to use the fmt= syntax with external methods. Basically, let's assume I have this piece of DTML:  If I add an External Method called HeadingFormat, that method should be called to format Heading, right? Well, this works partially, except that HeadingFormat() cannot take any parameters. Any reason for this? How, then, can I access the data to format? Looking at the code in DT_Var.py: if hasattr(val, fmt): print "calling %s" % fmt #!! val = getattr(val,fmt)() elif special_formats.has_key(fmt): val = special_formats[fmt](val, name, md) elif fmt=='': val='' else: val = fmt % val Shouldn't the line val = getattr(val,fmt)() say something like val = getattr(val,fmt)(val) instead? (Implementing the above patch seems to work, but is likely to break lots of things?) Did I miss something? Since chances are this is the case :-), how then do I implement a method to format arbitrary objects without actually modifying the Zope sources? -- Alexander Staubo http://www.mop.no/~alex/ "`This must be Thursday,' said Arthur to himself, sinking low over his beer, `I never could get the hang of Thursdays.'" --Douglas Adams, _The Hitchhiker's Guide to the Galaxy_

Also, if you want to send commands Zope, the best way to do it is use ZClient, which is a python based HTTP RPC like mechanism that lets you call Zope methods and objects from remote machines over HTTP. It allows you to easily specify users and passwords. look in lib/python/ZPublisher/Client.py -Michel > Thanks in advance :-) > > -- > robert canary > system services > OhioCounty.Net > rwcanary(a)ohiocounty.net > (270)298-9331 Office > (270)298-7449 Fax > > > > _______________________________________________ > 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 ) >

Evan, Thanks for the EXCELLENT post to the ZOPE Admin list (Digest Vol.1-#291-Message #1). I hope you, Evan, do not mind, but I 'reprinted' this post here: http://sohodojo.com/forums/Forum14/HTML/000001.html My primary interest in ZOPE is for the building of role-based executable business model frameworks (the technical side of our interest in 'ruthlessly small business' where the 'few heads, many hats' time management dilemma rules). You can find out more about 'ZOPE, Mirror Worlds and Executable Models' at: http://sohodojo.com/scripts/Ultimate.cgi In addition to the challenges of constructing these frameworks (I am an ex-Smalltalker who refuses to 'do Java'!), I am wrestling with the 'static/dynamic' problem as well, primarily for reasons having to do with search engine crawling, etc. I don't care what others' say. Of the search engines that count, my experience on our five sites is that there are plenty of situations where you had better have '.htm' or 'html' static pages, not even includes, if you want them indexed. (Getting hit doesn't automatically mean getting indexed, especially if the hit file is not parseable under the crawler's assumptions about HTML tagging.) So anyone with a commercial site (and not too big of an advertising budget!) that doesn't intend to use a combination of static and dynamic content is asking to become "The Invisible Site." I know, I saw it happen dramatically at one of our 'nano-subsidiaries', The Pop Culture Store. Months back, I thought I was so clever doing some nice Perl-based inventory management and item viewers.

Chris Petrilli here is working on a hashing out RDBMS details in preparation for the upcoming Zope 2.0 release. The result will be a report on the State-of-the-Database-Adapters. Specifically, he will identify ways in which various RDBMSes will be supported under Zope2. Of course, the introduction of concurrency in Zope 2 is having an impact on DAs. Chris' efforts will also result in a formal-ish announcement on the status of Gadfly. --Rob
