RE: [Zope] NESTED IN STATEMENTS AND PASSING VARIABLES in DTML
by Theodore Patrick 20 Jul '00

20 Jul '00

THANKS A TON!!! I just found that the following solutions works also: I think the only difference is the id is evaluated in the namespace variable before invoking the SQL_METHOD <dtml-in "active_category_method()"> <dtml-in "category_method(id=(_['id']))" size=100 start=query_start> id=<dtml-var id>&seq=<dtml-var seq>&vid=<dtml-var vid> </dtml-in> </dtml-in> or <dtml-in "1,2,323,23,23"> <dtml-in "category_method(id=(_['sequence_item']))" size=100 start=query_start> id=<dtml-var id>&seq=<dtml-var seq>&vid=<dtml-var vid> </dtml-in> </dtml-in> ------------------------------------ Your point on the SQL_METHODS is a good one! I had no idea! Theodore E.

Where 'id' > is and SQL_VAR for category_method. This is FAQ material and should be inserted into either the DTML programmer's guide or the ZSQL Methods guide. It bites everyone who uses SQL methods eventually. ZSQL methods do not perform acquisition, but will look at REQUEST, change it to. <dtml-in "active_category_method()"> <dtml-call "REQUEST.set('id', id)"> <dtml-in "category_method()" size=100 start=query_start> id=<dtml-var id>&seq=<dtml-var seq>&vid=<dtml-var vid> </dtml-in> </dtml-in> If you have a lot of arguments that need to be captured, you can build a DTML Method, say setup_category_method_parameters that has these builds the REQUEST. Then your dtml can look like: <dtml-in "active_category_method()"> <dtml-call setup_category_method_parameters> <dtml-in "category_method()" size=100 start=query_start> id=<dtml-var id>&seq=<dtml-var seq>&vid=<dtml-var vid> </dtml-in> </dtml-in> > > Thanks in advance! > > Theodore E.

RE: Reversing acquisition?
by Spicklemire, Jerry 20 Jul '00

"B" is acquirable by "C" and "D", because it is within the context of a common container, "A". However, some other object, "E" that is acquired from higher up the containment chain may be affected by the nature of the "B" that is available to "D". Because of that, the "E" may appear differently than it would if presented as a component from some other containment chain. An easy example to grasp is to think of "B" as defining the background color of a page. If "E" is the master page template, other "B" objects in other chains could define the color scheme for the all the objects ("pages") in the parent folder. That's context. -----Original Message----- From: Luciano Ramalho [mailto:luciano@hiper.com.br] Sent: Thursday, July 20, 2000 1:23 PM To: Spicklemire, Jerry Subject: Re: Reversing acquisition? Great ASCII illustration! I see what you mean. But I still donŽt see the difference between "containment" and "context" as defined in the AquisitionUsage Wiki (quoted below).

Incorrect Article: Zope Costly enterprise option
by Eric L. Walstad 20 Jul '00

20 Jul '00

Hi Tom and the editors at InfoWorld, In regards to your article titled "Zope is a powerful open-source server" FYI, ZEO is now open source and free. It's been that way since March 2000. Is it possible to fix your article before too many folks get the wrong idea? Here's a link to all the details: http://www.zope.org/Products/ZEO/ZEOFactSheet Thanks, Eric Walstad.

There's a good slide in Michel's presentation at the open source conference. Imagine: -------------------- | ----- --------- | | | B | | C | | | ----- | ----- | | | | | D | | | | A | ----- | | | | | | | --------- | -------------------- So that "A" is a folder, "B" is an object in "A", "C" is a subfolder in "A", and "D" is an object in "C". Then "B" is acquirable by "D", or any object in "C", but "B" is not contained in either "C" or "D". Later, Jerry S.

No. He got it wrong. ZEO is open-sourced, free, and available for download and has been since ~ a month ago. Write to the InfoWorld guy and tell him. :-) > -----Original Message----- > From: Brad Clements [mailto:bkc@murkworks.com] > Sent: Thursday, July 20, 2000 1:46 PM > To: zope(a)zope.org > Subject: [Zope] Infoworld Review of Zope > > > Sorry if this has been posted already, I'm in digest mode on > this list. > > http://www.infoworld.com/articles/mt/xml/00/07/17/000717mtzope.xml > > Is ZEO really $25K? > > > > Brad Clements, bkc(a)murkworks.com (315)268-1000 > http://www.murkworks.com (315)268-9812 Fax > netmeeting: ils://ils.murkworks.com AOL-IM: BKClements > > _______________________________________________ > Zope maillist - Zope(a)zope.org > http://lists.zope.org/mailman/listinfo/zope > ** No cross posts or HTML encoding! ** > (Related lists - > http://lists.zope.org/mailman/listinfo/zope-announce > http://lists.zope.org/mailman/listinfo/zope-dev ) >

Scarry BTreeFolder eats my 'contents' tab
by Dirksen Lau 20 Jul '00

20 Jul '00

Just as soon as I restarted Zope after placing the BTreeFolder in the Products dir, wham! all my files were disappeared!! It took me quite a while to collect the pieces of my minds and pulled them together again when I discovered through FTP that my files were still inside Zope. Back in the HTTP manage console I also found that the 'Contents' tab was gone, and it was the same with most of the folders in my Zope site. After removing the BTreeFolder from the Products dir, the 'contents' tab was back again. Everything seemed normal except the /Control_Panel/Products/ still had an entry of BTreeFolder. Really weild!! I'm running Zope 2.2.0b3 on NT4. Any idea to tame this beast is appreciated. RGDS Dirksen

Can anyone give me a push down the path of using the monitor client to access DTML methods. I have a s simple methods that returns a value from a SQL call. The method looks like this: <dtml-in getSample><dtml-var sample></dtml-in> I would like to examine sample in the monitor. -D
