Unfortunately it isn't quite clear to me what kind of site might be a right example to show off zope's capabilites in the area you asked for. But I know one zope site (not from my company) which is heavily database driven and might go in the right direction. It is in german, but that doesn't matter. They "broker" agricultural engines and other technical stuff for farmers, and are the greatest of their kind in germany: http://www.tec24.com/ Just klick on some links (e.g. "Schlepper") until you reach a form, then just submit to see some results. They have around 15000 items in their database, and the site runs well. Perhaps your programmer should post here at the list? ;-) cheers, oliver

I don't think that's what you want to do.

accessing overridden methods
by Brian Withun 18 Oct '01

18 Oct '01

I'm having a little difficulty with Zope inheritance. What I'd like to do is have a child folder (derived class) override a method foo() of it's parent (base class). In the child class, I want foo() to do it's thing and then call the overridden foo() method of it's parent. I have tried a child.foo() like this: child foo <dtml-with "PARENTS[1]"> <dtml-var foo> </dtml-with> but that introduced undesirable behavior by placing the PARENTS[1] namespace above the current (PARENTS[0]) namespace, so I tried: child foo <dtml-var "PARENTS[1].foo(_.None,_)"> but that didn't really work, either. The reason this fails is because "PARENTS[1]" is always relative to the object that was accessed in the current request. This leads to infinite recursion when I create a further-nested subfolder (BaseClass.Child.GrandChild.foo) Is there another way? ------------ Brian Withun Web Developer Hilgraeve, Inc.

Is anyone using XMLParsed out there? I am finding it really slooooooow. I have parsed a small XML document but it is almost unusable. Any one else have any experience? Thanks Dave

RE: [Zope] ZCatalog with OR expression
by sean.upton＠uniontrib.com 18 Oct '01

18 Oct '01

If this helps, ***within a single index***, dtml-in does "lazy concatenation" which works ok. Example query: http://classifieds.uniontrib.com/8000/results?displaymode=browse&getSection= 8572&sort_on=summaryfield&adDate:date=10-13-2001&adDate:date=10-14-2001 In this query, the adDate index is used twice, and 2 catalog queries are performed by the dtml-in iteration machinery, and concatenated together, and sorted together by dtml-in... I think that Casey's CatalogQuery product might give you OR across certain fields, but I'm not sure if there are any "perfect" solutions.

I'm trying to get an OR expression from a catalog: For example: <dtml-in "Catalog(meta_type='Image', title='Z*')"> So, this way I'm having objects with meta_type='Image' AND title starting with Z. Now, I need an OR expression: I need cataloged objects with meta_type='Image' OR with title='Z*' This can be done adding "two Catalogs: <dtml-in "Catalog(meta_type='Image')+Catalog(title='Z*')"> But... this way I get some objects two times: the ones filling both expressions.

aq_explicit only and DTML Document
by Behrens Matt - Grand Rapids 18 Oct '01

18 Oct '01

Let me try this again. There has got to be an explanation and/or workaround for this. I am beating my head up against the wall. Given a DTML Method that spits out a folder index that is acquired by subfolders with the following code: <dtml-in expr="objectValues('DTML Document')"> <dtml-var id>: <dtml-var meta_type> (<dtml-var summary missing="">) </dtml-in> Well, this mostly works but acquires summary from the containing folder or above if it is not set on the document. So I try <dtml-in expr="objectValues('DTML Document')"> <dtml-var id>: <dtml-with aq_explicit> <dtml-var meta_type> (<dtml-var summary missing="">) </dtml-with> </dtml-in> Same problem. So I now try <dtml-in expr="objectValues('DTML Document')"> <dtml-var id>: <dtml-with aq_explicit only> <dtml-var meta_type> (<dtml-var summary missing="">) </dtml-with> </dtml-in> and I get a KeyError. Apparently aq_explicit is empty inside a DTML Document? If I expand objectValues to include some of my other content types (File, Folder, etc.) 'aq_explicit only' works as expected. Anyone have any clue what gives here? -- Matt Behrens <matt.behrens(a)kohler.com> System Analyst, Baker Furniture
