ZCatalog and 'fuzzy logic'
by Morten W. Petersen 09 Jan '01

Is there anyone who could try to give an estimate of how long it would take to add fuzzy logic (regexp-like) searching capability to the ZCatalog? And reasoning as to why would be appreciated. ;) -Morten

When to use Rack , Folders w/Customize, etc.
by Johan Carlsson 09 Jan '01

09 Jan '01

Hi, Reading up on ZPatterns I'm still confused about some thing's (sometimes more, sometimes less). I wonder: When to use Rack, Folders w/Customize, attribute provider, sheetproviders etc. In which solution do I get ZODB dependens. One important aspect for some of my applications are to be as "virtual" as possible. (I hope this question is clear enough :-) Regards, Johan Carlsson

ZPatterns and ZClass Views
by Roch'e Compaan 09 Jan '01

09 Jan '01

I was wondering to what extent people using ZPatterns find the Views one can set up for a ZClass tolerant of the Role-centric approach followed by ZPatterns. For example: I have two Specialists, DocumentedProducts and Products. The Products specialist manages ZClasses of type 'Product'. Products are remapped to DocumentedProducts (where product plays the role of documented product). Typically in Zope, ZClass Views has bearing on a single Zope Object and Views are filtered according to User Roles, thus the focus is security. ZPatterns makes it possible to extend the roles an object has. Ideally the Views in a ZPatterns Application framework would be security AND role (the role the object plays) focused ie. when I look at a Product instance where it plays the role of documented product, I might have the views FAQs, HOWTOs, etc. But when I look at a Product inside the Products specialist I want the views Properties, Associated Files, etc. I like the idea of making the Views of a ZClass my starting point because at least it already filters according to the role a user might have. Any other ideas/comments? Roché

WikiName Overloading (RE: [Zope-Annce] ZWiki 0.8.1 released)
by Jay, Dylan 08 Jan '01

08 Jan '01

Here's the beef: Want to use ZWiki but have a slightly different version of what you want a wikiname to be? In my case I wanted to include TLAs as wikinames as my industry is full of them and its really handy to have to automatically hyperlinked so anyone can give the definition and references easily. To enable this I created a patch to ZWiki that will look for a property in the aquisition path called WikiNameDefinition. If found, this string property is treated as a regexp that is "or"ed with the standard wikiname regexp. This is done at runtime so you can change the wikiname over a pages lifetime. I would like this patch included so that I can take advantages of new ZWiki releases without rehacking the source each time. I'd like to motivate the author to include this feature in the next release. How much interest by others is there for such a feature? > -----Original Message----- > From: Simon Michael [mailto:simon@joyful.com] > Sent: Monday, 8 January 2001 9:29 PM > To: Jay, Dylan > Subject: Re: [Zope-Annce] ZWiki 0.8.1 released > > > "Jay, Dylan" <djay(a)avaya.com> writes: > > What are the disadvantages that you see? > > Nothing specific with your patch - just a general concern with feature > bloat and preserving simplicity and generality which makes me want to > consider how each new feature fits into the overall picture.

ANNOUNCE: PartitionedFileStorage
by Shane Hathaway 08 Jan '01

08 Jan '01

For all who are interested in breaking database size barriers without moving to Oracle or Berkeley Storage, here's something to try out. http://www.zope.org/Members/hathawsh/PartitionedFileStorage I *highly* recommend you back up Data.fs before installing. What is known to work: - Reads and writes of logical files greater than 3 GB on versions of Linux that support only 2 GB files. - Undo and packing. - Fast random reads and writes. - Using simple binary concatenation to move back to a standard single file. - Using PartitionedFile completely independent of Zope or ZODB. What has not been tested, but will very likely work: - Tranalyzer. - Putting the partitions on different physical devices. (Poor man's RAID :-) ) What couldn't be tested by my limited resources: - Platforms other than Linux. - Running this on a busy Zope site. (No, www.zope.org is not running PartitionedFileStorage. :-) ) BTW to all in the U.S., Happy Thanksgiving! Shane

Easy SQL question
by Keith.Larson＠Spatial.Com 08 Jan '01

08 Jan '01

Hello , I am trying to pull text from a Mysql DB into a page inside zope. I have the ZMYSQL connection setup and tested . for example : select renderText From Phrases where phrase_id = 3 and lang =1 I have also gotten the ZSQL method tested and working example : Arguments phrase_id renderText Query template select renderText from Phrases <dtml-sqlgroup where> <dtml-if expr="phrase_id"> <dtml-sqltest name="phrase_id" type="int" > </dtml-if> </dtml-sqlgroup> change and test enter 3 for phrase id and I get the correct info SQL used: select renderText from Phrases where phrase_id = 3 Now for the duh section. All of the above works fine with a submit button and entering info , I would like to pull the info into a Zope HTML page. I believe that this is close <dtml-call "REQUEST.set('phrase_id', foo)"> <dtml-in expr="langtest()"> <dtml-var expr="_['sequence-item'].renderText"> </dtml-in> but is foo supposed to be my var of whatever I want passed ? how do I pass the variable for phrase ID ( via a variable and changed per request ) to the language test and display the results so the user never knows . I think I am close just missing the obvious I think anyhelp ?

Michael Bernstein wrote: > > reindex_object - should be called when an object is edited Hmmm... didn't see this method listed in the interfaces wiki. Where did you find it? I just inserted a call to catalog_object which did the job but I wonder what the difference between index_object abd reindex_object and catalog_object is? cheers, Chris

Can you post a patch, or upload it to your Zope.org member folder and post the link? cvs -q diff -u lib/python/SearchIndex/Splitter.c would do it, if you were working in a CVS sandbox for Zope.
