HowTo: trying to acces only the form elements in the REQUEST ...
by Holger Lehmann 13 Mar '01

13 Mar '01

Hello everyone, I need a quick hint. How do I check wether there are any "form" elements in the request. And how can I only acces those ? I want to pass those, and only thos on to a ZClient call to another website. I do have a request like this: http://server/foo/bar?name=bar&param=foo&param2=baz Now I want to isolate name, param and param2. I need to construct a request like this: <dtml-if <any parameters at all>> <dtml-in <all form parameters in REQUEST>> ..... do something </dtml-in> </dtml-if> TIA Holger -- ----------------------------------- catWorkX GmbH Dipl.-Ing.

My inclination exactly. I would feel so much better if all these geniuses would just jump "straight to Go". It seems, though, that they have to work through this "unproductive" prototyping stage in order to get there. Of course, I can't complain, since just watching the breakneck evolution of Python, Zope, ZPatterns, and all the amazing goodies that show up here and at Zope.org leave my head spinning. If I recall, the original RIPP slide presentation stated pretty clearly that the toolkit that came to be called ZPatterns was really just the groundwork needed to achieve a much larger goal. So, TransWarp is that much closer to reality, and it took ZPatterns to make that happen. The stamina alone is mind boggling, let alone the fact that useful stuff, _very_useful_stuff_, was generated along the way. also: > I expect the ZPatterns-based e-commerce app > I'm building today to make the e-commerce app I build in 12 months a > lot easier to build. So any changes in the basic tools I use bother > me. Me too. My preference is to have only the best solutions right from the start, and to only have to learn things once. Problem is, after 14 years doing this stuff, none of it has had the simple courtesy to just stand still! The good news is, for the most part, the trend is in the general direction of improvement. Again, how can I complain? I don't pretend to fully "get" any of the stuff these guys, nor the DC crew, not to mention the PythonLabs team, and all the astounding folks on the lists are cooking up for the rest of us. All that I can say for certain is that based on past history, it will be even more amazing than the stuff that has me totally dazzled already. One thing that has definitely grabbed my attention about TransWarp is the goal of not only making Zope development more flexible and powerful, but to bring the same facility to "Extra-Zope" development. We all hang out here because of the incomparable degree to which Zope has empowered Web development. But Jim Fulton himself has said how tickled he is that folks are starting to use ZODB independent of Zope. Zope is, after all, an amalgam of several Python modules, any one of which can be pulled into a non-Zope application. Right now, at this point in time, the Web is absolutely critical, and anything that helps us deal with the crude state of the Web (e.g. browser hell) is a life-saver. So, Zope's greatest strength is its Web-centricity, but it can also be it's Achille's heal, once the Web reaches maturity, and technology moves on. Something like TransWarp can assure that all the goodies that we build for Zope can continue to live on and remain viable, long after "The Web" is a quaint artifact, a footnote in the primitive history of an ubiquitous Global Communication System. Thanks Phil, Ty, Jim, Brian, Paul, Shane, Tres, Michel, Amos, Guido, Tim, Ken, and way too many more to mention! Jerry S.

ZmxODBC DA
by Bryan Baszczewski 12 Mar '01

12 Mar '01

I am curious of how popular SQL Server is among Zope developers. We have recenly upgraded from SQL 7 to 2000 and noticed most of the database support for Zope centers around Oracle, MySQL, Postgres, Sybase, etc... How many people are using this ZmxODBC database adapter? And what kind of problems/issues/praise do you have?

zWiki and Chinese
by Sin Hang Kin 12 Mar '01

12 Mar '01

I am trying to fix zWiki for Chinese. What I did is to remove for c,e in intl_char_entities: t = re.sub(c,e,t) from _text_cleanups of ZWikiPage.py Then, I modify all forms to make them set utf-8 as default encoding. After that, every thing seem working. The only problem for me is that I can not create new pages with name in Chinese. Because the way that wiki is create, it is very limited and ugly to include some unrelated WiKiNames in the middle of the text, and the link nevery self-explain. Is it possible to include quote or other encoding methods such that the utf-8 encoded text between [] were always converted to a correct ZODB id? Which might solve the currently id problem for zope? Moreover, zWiki use regular expression on the utf-8 text as if they were ascii. Is it possible to convert it to unicode before applying regular expression? Or can we store them as unicode?

Zope not start as win2000 services
by kent sin 12 Mar '01

12 Mar '01

Zope installed from binary can not start as service on NT after modified been made to pythonpath registry. Before that, it runs. The event log says: string object has no attribute upper. Does this means some conflict between the python2 and the 1.52 from zope? Can somebody give me instructions to solve this?

_getOb or __getattr__?
by Chris Withers 12 Mar '01

12 Mar '01

Hi, I need a product with custom attribute getting code and so looked to the BTreeFolder product for inspiration. It implements both __getattr__ and _getOb which appear to do roughly the same thing. What's the difference? Shane hints that __getattr__ is slower but allows acquisiton. Why is that? TIA, Chris

Is ZFormulator alive?
by erickson＠kaivo.com 12 Mar '01

12 Mar '01

ZFormulator looks like it will do some pretty neat things, but it also looks like it is "dormant". Does anyone use it, or know if it is compatible with Zope 2.2.x and/or Zope 2.3? Thanks -paul

SAP DB <--> ZODB ?
by Spicklemire, Jerry 12 Mar '01

12 Mar '01

Kapil said: > looks like it will instantly become the most advanced open source database > out there. my current rankings of the general os rdbms in terms of features > postgresql->interbase->mysql Keep in mind that (even though) it is an effective "general os rdbms", PostgreSQL was originally developed as an experimantal platform for testing concepts in the Object-Relational database realm. As such, it has some unique potential, especially in its ability to define and store Objects as _native_data_types_. Most of the effort and press related to PostgreSQL in the recent past has focused on adding SQL in place PostgreSQL's QEL, and improving stability and performance. Now that most of this important work has been accomplished, my hope is that some of the truly differentiating features can be showcased, e.g. a Zope Storage where an external SQL engine can directly interact with objects as native data. Imagine a SQL statement that updates every instance of a ZClass with new properties, or slipping a super-class in underneath (re-parenting), where it had never been before. also: > the feature list of this database is astonishing > www.sapdb.org > > to name a few > subtransactions > outer joins > sql 92 compliant, possible modes for db2, oracle 7 > very nice prodecural sql language. > lots of statistics information > really rich set of standard functions > scrollable cursors > > this is a great candidate for a zodb storage SAP DB is a fully licensed version of Software AG's (SAG) Adabas D, a descendant of SAG's venerable mainframe class system, Adabas C. Yes, SQL is fully supported, but SQL is after all a query language, not a physical model of the internal structure of an rdbms. This is not to say that Adabas, in any form, is any less of a capable system. Don't be surprised, however, to find something much closer to a network database under the surface, compared to PostgreSQL, which is about two generations newer, according to its "birth date" (1988?). Interestingly, many folks who have been around for several "database revolutions" see the network model as a very good choice for storage of "non-tabular" data types, such as objects, etc. On the other hand, that may be the result of lack of familiarity with the possibilities inherent in a true Object-Relational data model.

Ensuring 'freshness' of dynamic pages (slightly offtopic)
by Morten W. Petersen 12 Mar '01

12 Mar '01

Hi guys, I've been trying to ensure that documents from a certain website are always fresh, that is, every request for a new page must be validated before the client sees it. I've tried using these HTTP Cache-control directives: no-cache no-store max-age (1) must-revalidate but no such luck. If I for example specify 'Check against server: Never' in IE, the pages are cached, no matter what. Is it possible to ensure that pages are always fresh, even if it is specified on the client side that the client should never try to retrieve a 'fresher' page? I've been contemplating a new solution, which is to append a string like ?ensure_freshness=02349025180.12 (some random, unique id) on each link, but that's not a thing which I wish to do now, at such a late stage in the project. Also, it strikes me that it isn't possible to specify multiple cache-control directives with the current HTTPRequest implementation, am I missing something here, or is this a bug / missing feature? Any ideas? Thanks, Morten
