DocumentTemplate with a (bigger) brain
by M. Papillon 14 Mar '00

14 Mar '00

Hello all, I'm an old bobo fan who hasn't done much with the full zope. For the record I'd like to encourage y'all to keep things modular - everyone of us can benefit from parts of zope even if we can't - or aren't allowed - to use the whole thing. Anyway, I've got a horrendously complicated site I'm working on with loads of really, really ugly javascript for things like fancy buttons, menus, &c. The typical widget has an external javascript file, plus css on each individual page, and then a bunch of divs and images that are document.written on the client side when the page is loaded. (Please don't flame if this is flawed, I'm not a Real Programmer [yet]) Thus you have three places where the page is affected by a widget: <head> [script: external javascript file] [css definitions] </head> <body> [html defining widget] </body> I would like to define a widget object that can display itself through dtml, but I wonder if dtml is capable of such a thing. When parsing a template, it would need to backtrack and insert additional css and/or a new external script tag at the top of the page. Here's what I want as input: <head> <title>check the fancy butts d00d!</title> </head> <body> <dtml-var super-cool-button> </body> And output: <head> <title>check the fancy butts d00d!</title> <script src="fancybutt.js"></script> <style> #butt1 { position: etc } </style> </head> <body> <div id="butt1"> etc </div> </body> Of course if there are two buttons on the page, this gets more complicated as each one will need to have unique names, and they will probably also have to be initializes onload. Thus the tag needs to have 1) some sort of memory, and 2) needs to be able to affect parts of the page outside the scope of the tag itself. So - can this be implemented with DocumentTemplate, perhaps with a custom dtml tag? Will it have to be done in two passes, or is there an idea for a better way? Or even better, has anyone else come up with a nice widget implementation?

Text Index of a lines Property
by Jason Spisak 14 Mar '00

14 Mar '00

Zopists, This is probably a simple question, but can I create a text index on a 'Lines' property? I have tried so far to query it with little sucess. I have generated a keyword index, but text is better because of it'sa bility to 'AND' searches. All my best, -- Jason Spisak 444(a)hiretechs.com

Adding zclasses to subfolders
by Brett Carter 14 Mar '00

14 Mar '00

I am trying to add a zclass programmatically to a subfolder in another zclass - I've checked the archives and documentation, and haven't been able to figure this out. If I am inside ZClassA and want to create a new instance of ZClassB inside the folder 'bar' which is in ZClassA, it seems you would do something like this (from inside ZClassA): <dtml-with "manage_addProduct['DocumentAppProduct']"> <dtml-call "bar.ZClassB_add(_.None, _, NoRedir=1)"> </dtml-with> but I get an unauthorized error saying I don't have access to 'bar', even though the calling method has a manager proxy role.

Zope memory usage
by R. David Murray 14 Mar '00

14 Mar '00

OK, so just what determines Zope's memory usage? I naively assumed that beyond a certain minimum size it would be the object cache. But my zope process seems to just keep growing. If I go to the' database management page and flush the cache, the size doesn't change. I need to understand at least a little bit more about the memory profile, because the Zope process is periodicaly consuming all available swap space and I have to restart it. I'm sure the fact that I'm touching a lot of objects in the database (a couple thousand) is part of the problem, but I'm doing it in batches of 250, so I would think Zope's memory management could handle that. On a possibly related issue, I turned on the stupid file logger, but now I occasionally get an error page with the following traceback: Error Type: TypeError Error Value: call of non-function (type file) <!-- Traceback (innermost last): File ...Zope-2.1.2-src/lib/python/ZPublisher/Publish.py, line 214, in publish_module File ...Zope-2.1.2-src/lib/python/ZPublisher/Publish.py, line 179, in publish File ...Zope-2.1.2-src/lib/python/Zope/__init__.py, line 202, in zpublisher_exception_hook (Object: ElementWithAttributes) File ...Zope-2.1.2-src/lib/python/ZPublisher/Publish.py, line 165, in publish File ...Zope-2.1.2-src/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: reindex_database) File ...Zope-2.1.2-src/lib/python/ZPublisher/Publish.py, line 102, in call_object (Object: reindex_database) File ...Zope-2.1.2-src/lib/python/OFS/DTMLMethod.py, line 145, in __call__ (Object: reindex_database) File ...Zope-2.1.2-src/lib/python/DocumentTemplate/DT_String.py, line 502, in __call__ (Object: reindex_database) File ...Zope-2.1.2-src/lib/python/DocumentTemplate/DT_In.py, line 611, in renderwb (Object: Catalog) File ...Zope-2.1.2-src/lib/python/DocumentTemplate/DT_Let.py, line 145, in render (Object: objid=id) File ...Zope-2.1.2-src/lib/python/DocumentTemplate/DT_With.py, line 148, in render (Object: getobject(data_record_id_)) File /usr/local/src/zope/Zope-2.1.2-src/lib/python/Products/ZCatalog/CatalogAwareness.py, line 191, in reindex_object (Object: CatalogAware) File /usr/local/src/zope/Zope-2.1.2-src/lib/python/Products/ZCatalog/CatalogAwareness.py, line 181, in index_object (Object: CatalogAware) File ...Zope-2.1.2-src/lib/python/Products/ZCatalog/ZCatalog.py, line 344, in catalog_object (Object: ElementWithAttributes) File ...Zope-2.1.2-src/lib/python/Products/ZCatalog/Catalog.py, line 356, in catalogObject File ...Zope-2.1.2-src/lib/python/SearchIndex/UnTextIndex.py, line 243, in index_object File ...Zope-2.1.2-src/lib/python/SearchIndex/Lexicon.py, line 129, in set File ...Zope-2.1.2-src/lib/python/ZODB/Connection.py, line 409, in setstate File ...Zope-2.1.2-src/lib/python/zLOG.py, line 198, in LOG File ...Zope-2.1.2-src/lib/python/Zope/ZLogger/ZLogger.py, line 18, in log_write File ...Zope-2.1.2-src/lib/python/Zope/ZLogger/stupidFileLogger.py, line 40, in __call__ File ...Zope-2.1.2-src/lib/python/Zope/ZLogger/stupidFileLogger.py, line 99, in stupid_log_write TypeError: (see above)

Announcement: New Zope-XML list
by Martijn Faassen 14 Mar '00

14 Mar '00

Hi there, Since I feel there needs to be a common place where people interested in combining Zope with XML can do their talking, I've created a Zope-XML mailing list. The intent is to discuss Zope's XML infrastructure, and in particular: * use of the present infrastructure * improving the infrastructure * creating new infrastructure Anyone interested in XML and Zope please go here: http://www.egroups.com/group/zope-xml/info.html to join! Regards, Martijn

Zope is Broken in CVS

I was trying to play around with the latest version of Zope and the PTK from cvs. After compiling zope i tried to run it and get the following error (without PTK installed). CVS commands i tried the standard cvs checkout Zope2 and later tried cvs up -Pd to no avail. any ideas?

Re: [Zope-dev] Problem uploading large files

Another tool might be a logging > proxy, that will tell you where the protocol breaks down, and whether > there is anything funny with the HTTP header lines. There is Wsnitch > on the Gnome site, and another one I can't remember the name of > on the python.org site. I've used the latter one some months ago. We switched Medusa with Apache, and everything works perfectly. I take this as a pretty stong indication that there is something wrong in the Medusa code base somewhere. I'm not competent enough to sniff it out, But Medusa obviusly has problems handling uploads that use 30-40 minutes or more. We would like to be able to use the ZServer/Medusa combination, but as of now we have to run Apache/PCGI so our customers can complete their uploads. If you need more information from us on this, don't hesitate to contact us. We'll be as helpful as we can in hunting down the bug(s). Regards, Alexander Limi. http://mp3.no
