Jason: OK, I took out the redirection <dtml-if> in the constructor. The DTML test method returns the id. > A few weeks ago I was having this same problem and I encased the entire > thing inside the 'if' and took it out and both worked fine. So... you're suggesting that... I encase the whole constructor method in this redirect dtml-if? OK: I deleted the search and report interfaces (report being jacked) and then created new ones. When I view "report" now, the new instance's properties appear along with all the old ones. Cool! So Catalog is getting reindexed OK and I am happier. However, when I try to search the new instance (by whatever property), _report says there's no data matching the query. What's up with that?

Hi all, myCatalog is configured correctly: indexes are specified, metadata columns are set up, subtransactions disabled, etc. New myClass instances show up in Catalog (I've got it named correctly -- good shot, Tres) but not their properties. I can get at the properties of these newly-created instances via DTML, which means that myClass's add constructor method is doing everything right but forcing Catalog to index new instance properties. Jason, I used your test methods and you're exactly right: Catalog reindexes the new instance only when I force it to as you suggested. Everything is OK until I add another new instance. And now here's another problem: these new instances cannot be deleted or cut and pasted. What happens when I try to do either is that the right management screen goes blank and then tries to reload itself without success -- ad infinitum. I can only stop it by hitting "stop", and Zope tells me some resource was not found but gives me no traceback. Whattheheck? Bloodied but unbowed, Anthony (I'm using Zope 2.1.6 with Linux2) _______________________________________________________ Get 100% FREE Internet Access powered by Excite Visit http://freelane.excite.com/freeisp

I put a bug in the Collector on this back in January: http://classic.zope.org:8080/Collector/995/view The problem is that the sendmail tag pushes itself onto the top of the namespace stack, and so values like 'id' and 'title' are handled in its acquisition context, rather than your document. A workaround is to alias the values you need before starting the sendmail tag:: <dtml-in "objectValues(['DTML Document'])" <dtml-let docTitle=title> <dtml-sendmail smtphost="imeme.net"> To: &dtml-docTitle; <<dtml-var email>@imeme.net> From: imeme <admin(a)imeme.net> Subject: imeme <dtml-var body> </dtml-sendmail> </dtml-let> </dtml-in> Tres. -- ========================================================= Tres Seaver tseaver(a)digicool.com tseaver(a)palladion.com

Confused about manipulating dates in DTML
by Skip Montanaro 21 Apr '00

21 Apr '00

I have some objects that represent dates in ISO 8601 format, e.g., "2000-04-21". Within my DocumentTemplate I'd like to present those dates to users in a little nicer format. With the attribute "start" containing the date I tried: <dtml-var "_.DateTime(start).Date()"> This yields a TypeError during rendering: ... File /usr/lib/python1.5/site-packages/DocumentTemplate/DT_In.py, line 691, in renderwob (Object: entries) File /usr/lib/python1.5/site-packages/DocumentTemplate/DT_Util.py, line 321, in eval (Object: _.DateTime(start).Date()) File <string>, line 0, in ? TypeError: illegal argument type for built-in operation I then tried: <dtml-var "_.DateTime(start)"> but got the same error. Table 2 in the DTML manual states: DateTime(): Create a DateTime object from zero or more arguments. See Appendix A, Date-time data on page 41. Unfortunately, Appendix A only has this to say about creating DateTime objects: From DTML, the special variable _ provides a method for constructing date-time values from strings and numeric data. but gives no details about how to call the DateTime constructor. It seems to only list the attributes understood by DateTime objects. It gives no clues (that I can see) about how to actually create DateTime objects from strings. On the assumption that Zope's DateTime stuff is just a wrapper around Marc-Andre Lemburg's mxDateTime I tried: <dtml-var "_.DateTimeFrom(start)"> thinking that constructor might just not have been documented. Calling it yielded an AttributeError for DateTimeFrom however. What's a poor fella to do? Thx, -- Skip Montanaro | http://www.mojam.com/ skip(a)mojam.com | http://www.musi-cal.com/

Limiting & Counting A Tree
by J. Atwood 21 Apr '00

21 Apr '00

I am playing around with ZDiscussions trying to being it up to date. Since it uses <DTML-TREE> as its main building of the list I have a few questions. 1) How do I limit the amount of items displayed in a tree? I tried <dtml-tree branches="children" size=10> but it did not work. 2) How do I count the amount of children in a tree? Thanks, J

sendmail and namespace
by mindlace 21 Apr '00

21 Apr '00

Zopistas, Why doesn't this work in a method? <dtml-in "objectValues(['DTML Document'])" <dtml-sendmail smtphost="imeme.net"> To: &dtml-title; <<dtml-var email>@imeme.net> From: imeme <admin(a)imeme.net> Subject: imeme <dtml-var body> </dtml-sendmail> </dtml-in> It gets the values for title from the folder that contains the method, not from the DTML Document that's supposed to be on top of the namespace. I tried <dtml-sendmail smtphost="imeme.net"> <dtml-with "_['sequence-item']" only> To: &dtml-title; <<dtml-var email>@imeme.net> From: imeme <admin(a)imeme.net> Subject: imeme <dtml-var body> </dtml-with> </dtml-sendmail> and that doesn't work either. -- ethan mindlace fremen mindlace(a)imeme.net zope -&- imap email -&- mailing list weave your web with the web at http://imeme.net

ZCatalog PrincipiaSearchSource
by Gijs Reulen 21 Apr '00

21 Apr '00

Hi Stupid question I guess because from the archives I understand nobody asked it before: I implemented the ZCatalog and ZSearch as decribed in the how-to 'Z Catalog Tutorial'. As next step I would like to modify the search form by removing all fields except 'raw' because my visitors should only input simple text queries. However, turns out the report methode needs PrincipiaSearchSource defined, meaning I have to include it in the search form ?! I must be missing something .... Gijs Reulen

Re: [Zope] ZClasses and ZCatalog: reindexing problem
by Anthony Monta 21 Apr '00

21 Apr '00

Thanks Jason and Kevin for the prompt replies. But in fact my _add constructor method had been changed to include the reindex module, just as in the example below: > <dtml-with "createInObjectManager stuff...." > <dtml-call "propertysheets.YourPropSheet.manage_editProperties(REQUEST)"> > <dtml-call reindex_object> > </dtml-with> And that's what puzzles me: it doesn't work. I tried doing this: > <dtml-call reindex_object()> thinking (flailing) that "()" would specify "the current REQUEST properties" even more specifically. But I'm wrong, and it doesn't work, and I'm still at wit's end.
