[Zope-dev] ZPatterns Design Issue
Hi Everybody We are porting a desktop application to Zope using Interbase and ZPatterns. In this application objects like Vintage, Farm, Vineyard, Block and Panel form a hierarchy and are displayed with the Zope tree widget. To build the hierarchy we use a method called getChildrenFor() on each level to retrieve the children for the object at hand. Behind getChildrenFor() lies a ZSQL Method on their respective racks to retrieve the result set. Building the tree leads to a whole bunch of queries to the database that really slows thing down ie. besides the queries that retrieve children, select queries to retrieve individual instances is called by getItem through SkinScript for each item in the tree. I haven't been able to figure out a way to get some performance back without talking to the database directly through ZSQL Methods but this defies the whole point of using ZPatterns. Some guidance/pointers would really be appreciated.

[Zope-dev] ANN: new CalendarTag and other news
Hi all, I've working a little in a new CalendarTag, you can download it (version 2.0 alpha 1) from http://sourceforge.net/projects/lleu Be careful, its usage is somewhat different and will probably break the pages that use the old CalendarTag. It's not for production environments, it's mainly for getting feedback, if there's a feature you want to see in the new Calendar Tag let me know. Note that the new version depends on the product mxDateTime that you can also download from the same url. Other news, the Localizer product is updated, the version 0.1.1 fixes two bugs of the 0.1.0 version. If you're curious look at the CVS, there you'll find an unreleased product named Content (yes, it's not a very good name). Combining both the Localizer and Content it will be possible to easily build big multilingual web sites.

[Zope-dev] Splitter.c hack by Spisak; anyone have a Splitter.so?
Hola, please don't make me touch C or a ... erm... you know, one of those compiler-thingys. I don't like them. Does anyone have a nicely baked Splitter.c for Linux? The one that Spisak hacked to make it chew and swallow anything? Fhank you very much. :-) ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )
RE: [Zope-dev] ZPatterns Design Issue
How do you bind a SQL Result with multiple records with multiple instances of the class? Can you do this in Skinscript? Or do you mean I should return the sql result directly? Roché Why don't you just have the rack's getChildrenFor() method return instances of the correct class, with all the data filled in from the SQL method? There should be no need to re-retrieve the same items with getItem(). Note, by the way, that this does not violate encapsulation, since the specialist and racks are specifically the place to put implementation-specific versions of multi-object methods like this. (Btw, if anybody's compiling a ZPatterns FAQ, this should probably get in there.) ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )
[Zope-dev] deepcopy of file object
Hi, I've got an object of type OFS.Image.File and I want to make a copy of it. I can't use the ObjectManager stuff, 'cos this object is being stored in a BTree-ish thing in a quite different context from a Zope folder. For obvious reasons, deepcopy(myfileobject) fails with a copy.error 'cos I don't see the File class having a __deepcopy__ method. Has anyone got any ideas or things that I might haev overlooked. cheers, Chris ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )
[Zope-dev] ZPivotTable
Hi guys, I want to program a pivot table similar to the one M$ Excel has. I feel there's the need for it. For the planned features see http://www.zope.org/Members/freiser/PivotTable/ I've thought that it would be best if I would create the following classes: - Cell (The table cell) - Column (The table column) - Row (The table row containing columns and cells. Columns only if one or more columns are drilled down) - Table (The table itself) Could you give me some advice if I'm on the right path, and give me alternative design ideas?

[Zope-dev] wxPython + ZODB = bliss
Here is a script that lets you browse *everything* in your ZODB through a quick GUI client. I was looking at wxPython the other day and this idea occurred to me. It worked amazingly well. http://www.zope.org/Members/hathawsh/pyTree (BTW you can't hold me responsible if your password slips out because of this. ;-) It runs outside the security model. ) I don't know how many of you have tried out wxPython but I think it's a marvellous GUI library. It's fast, stable, and in active development. It works as well under Python 2.1 as it does under 1.5.2. Just thought I'd give that little plug. :-) And when you mix wxPython with ZODB... it's pure bliss. I've been writing a little program on the side that uses wxPython and ZODB as a foundation, and I'm amazed at how well the project is coming together. I've heard rumors about a fat client for Zope that used a ZEO connection for editing (ZopeFish?)... I think this script demonstrates how well that idea would work!

[Zope-dev] forking of the mailing list
There was a discussion on [EMAIL PROTECTED] about forking of the mailing list. Would there be any support behind a seperate ZPatterns list? There seem to be lots of users and lots of questions that arent of interest to people who dont use ZPatterns (like me). Cheers. -- Andy McKay. ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )
