I'm learning the ZOPE, but have met much problems.I have installed "plone" in my system Window XP, and have created a dadabase on my zope.I want to put it into csv, so I have downloaded DSV 1.4.0 from the site of zope, and put it into my folder /zope/lib/phthon/products, but I can not find it in the "select type to add..."of root folder, would you please help me? Thank you very much! LEI zhiyi

Re: [Zope] Zope Best Possible Installation
by Jaroslav Lukesh 13 Jun '03

Instead of apache, use (not only load balancing) reverse proxy pound (www.apsis.ch/pound) Apache is as mamut, with pound you could not define virtual domains at two places, only in VHM of Zope. And is much safer than apache. Install & config of pound is easy. I have use pound as redirector for zope and for apache. And of course use Linux (BSD has some problems with stack size or so). I have Mandrake 9.1 (with XFS filesystem), Zope 2.5.1, pound 1.3 and all works wery fine without any problems with very good performance (much more better than from windows which I used before). And of course do not use "on-board" network interfaces (from intel - in heavy load it will lock whole system) If you will have multiprocessor machine, you could set local ZEO cluster (pound will help you with that to do loadbalancing).

Zope certainly performs better on Linux than any other OS I've run it on (particularly Windows and Solaris). The Apache config is pretty straightforward in most cases, and can probably wait, unless you've got a better handle on your front-end requirements than you've expressed here.

Thanks. I did some digging into the zope-dev archives and yes, version objects are a mess. We're retreating and looking for another solution -- likely CMFStaging. -- J C Lawrence ---------(*) Satan, oscillate my metallic sonatas. claw(a)kanga.nu He lived as a devil, eh? http://www.kanga.nu/~claw/ Evil is a name of a foeman, as I live.

OK i've looked at the code behind the add item in the ZMI and i am lost. If the onchange was to trigger a DTML method called "RoomBookingForm" what would the code look like? thanks garry

Has anyone done something in python/zope to allow for searching by number of miles from a zip code? I see this on many sites and wonder how to incorporate it into my site. sean

ZSQLMethodFile?
by Peter Bengtsson 12 Jun '03

12 Jun '03

Just like there's DTMLFile and PageTemplateFile, what about ZSQL Methods? So that you can run ZSQL methods from the filesystem (for a python product) If not, I'll have to open my filesystem files and programmatically create these objects.

Unicode strings and search
by Vladimir Petrovic 12 Jun '03

12 Jun '03

Dear all, In the zope application I'm developing I'm using unicode strings that contain non-latin1 characters. I've solved "standard" problems with conversion exceptions from/to unicode in the way that is described in previous messages in the list (I've also used setdefaultencoding ('utf-8') since all of the non-unicode strings are in this format). However, regarding the full text search, situation looks more complicated: (1) "Old" Zope Text Index. This index works properly when UnicodeSpliter is used. Unicode properties are indexed, and it is possible to query with star. (for instance: searchResults ( {'ind':'_.unicode ('<alpha>*', 'utf-8')}) works properly. (2) ZCTextIndex. As far as I played with it, it doesn't have unicode splitter. The two splitters I've tried don't work with non-latin1 characters. Lexicon will not even show correct number of words - not-latin1 words are ignored. (3) TextIndexNG (1.09). This index properly divided text in words. However, querying the index with * doesn't produce results if non-latin1 character is used. Querying full words works: - searchResults ({'ind':_.unicode ('a*', 'utf-8')}) - works - searchResults ({'ind':_.unicode ('<alpha><alpha>', 'utf-8')}) - works - searchResults ({'ind':_.unicode ('<alpha>*, 'utf-8')}) - doesn't work. I want to use one of the newer text indexes because of the capabilities they provide. However, I can only make the old index works with unicode text. Does anybody have an idea how can I make (2) or (3) work with arbitrary unicode text. Thanks in advance, Vladimir

Non-bloating counter/access logger solution
by Wankyu Choi 12 Jun '03

12 Jun '03

Hi all, I know the topic has been discussed a lot but I found little help so far. I want to implement a simple counter or a complete access logger for ZOPE objects. Here are my (and many others') problems regarding this: - ZODB bloats. Whenever the value of a counter property gets updated, the host object is copied doubling its size. - Too many read/write conflicts. No matter how little traffic you expect, you get tons of read/write conflict errors. I thought about saving counter values/logs in an external storage like a MySQL table or an external file in order to dupe ZODB into thinking no change has been made to the object in question. But that doesn't seem so elegant and generic. Please share your ideas resolving this issue. I have yet to study the internals of ZODB, but can't it have a way to update only the designated properties of a persistent object? If not possible, why? ( to avoid bloating ZODB ) Committing a whole object when its access log gets updated lead to excessive conflict errors. By updating only the counter property, for example, the odds of having conflicts would decrease to a substantial degree.
