Zope CMF blackout
by Chetan Kumar 30 Aug '02

30 Aug '02

Hi all My CMF based site suddenly started giving problems. It started about 30 mins back when I got a lot of warnings like the POSTDATA not being in cache while I tried to save the python script I was working on. I clicked "yes" once and "cancel" another time. At about the same time I noticed that the CMF Default product was broken !! I wonder what happened. I am using Zope 2.5.1 and CMF 1.3. The error message here says something about DateTime. I installed the DateTimeNG-0-0-1 a few days back. I think the server was not restarted after that. The CMF Default does not show in the drop down menu I am :-( -----------------------------------Error Message----------------------- 2002-08-30T14:35:58 ERROR(200) Zope Could not import Products.CMFCalendar Traceback (innermost last): File /home1/sepg/Src/lib/python/OFS/Application.py, line 531, in import_produc t File /home1/sepg/Src/lib/python/Products/CMFCalendar/__init__.py, line 13, in ?

dtml-lesson learned...
by Maik Jablonski 30 Aug '02

30 Aug '02

hi, I've just learned my DTML-lesson... Don't use DTML for any program-logic!!! Not even the small bits... Debuged 3 hours... if've used this snippet for months and it worked well... <dtml-return "_['title'][_['title'].find('#')+1:]"> today it stopped working with an "access denied"-error... don't ask why... I've no idea, but maybe I've touched a guarded-namespace... typical DTML-mystery. this python one works well: return context.title[context.title.find('#')+1:] ergo: don't use DTML for logic, use Python! maybe: don't use DTML for presentation, use ZPT [I'm not totally convinced of that by now, but especially for Chris W.: maybe I will following your ZPT-church in the near future too...;-)] cheers, maik -- Maik Jablonski __o www.zfl.uni-bielefeld.de _ \<_ Deutsche Zope User Group Bielefeld, Germany (_)/(_) www.dzug.org

Something like ezPublish in Zope....
by Jorge O. Martinez 30 Aug '02

30 Aug '02

Hi: First of please don't flame me if I sound like a devil's advocate here... Does anybody know of a product as complete/mature as ezPublish (a CMS built with PHP/Mysql, it's at http://publish.ez.no) in Zope? I have checked out CMF, and Plone, but although they are very nice, in the case of CMF, it seems that it does not have all the features that ezPublish has out of the box, and with Plone, there's still no 'stable' release as of this writing. Besides, both of these products seem oriented mainly towards building collaborative web sites where all members eventually post news and info, and do not seem to be oriented towards 'topic and/or category' driven sites maintained by a handful of people only. I am not saying it cannot be done with Zope. I have also checked ZopeZen's code, but it's not as full-featured as ezPublish. I know zope has the basis to build everything that exists in ezPublish, but I was wondering if there's a Zope CMF that's similar in features and stability as ezPublish out of the box.

Attrib exceptions and None objects under heavy load?
by Etienne Labuschagne 30 Aug '02

30 Aug '02

I am currently (mis?)using zope as the base for a persistent message queueing system. I have created various Zope classes in Python (message, topic, node, etc.) and will typically create a lot of message objects in a topic object (topic inherits from folder), while reading those messages at the same time AND distributing them to other zopes. This means that there is a lot of object creation, reading and deletion going on from multiple threads. I will typically use getObjectValues to loop through the objects in a container and then handle each object. Sometimes I get the following exceptions: None type does not have attribute bla bla - as if the object I get is a Python None and not the actual object Attribute error when calling a method on a object, even though that object has the relevant method (this one happens a lot). ie. AttributeError: addMessages on a Topic object, even though Topic class has a addMessage defined. The funny thing is, I never get Conflict errors (according to the Zope developer guide, that is what typically happens when multiple threads hit a ZODB). Any suggestions? Thanks Etienne P.S. This message queue product is probably in a state now where I can give it to the community if anybody feel they need something like this and want to contribute to the development.

Yes, I'm awaiting this earerly. No win32 binary yet however.

HTTP_ACCEPT and flash content
by Lee Harr 30 Aug '02

30 Aug '02

Hi; I was thinking of adding some flash to our site... (i know, i know.. NOOOO!) Anyhow. I thought it would be ok as long as the flash was not being sent out to browsers that cannot play it. I figured that the HTTP_ACCEPT variable should have something like: "application/flash-5" or something... But looking at a test page it does not appear to be so. I just made a python script with: return context.REQUEST >From mozilla (with no flash plugin) I get: HTTP_ACCEPT'text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,video/x-mng,image/png,image/jpeg,image/gif;q=0.2,text/css,*/*;q=0.1' And from Netscape 7 beta (with flash 5 plugin) I get: HTTP_ACCEPT'text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,video/x-mng,image/png,image/jpeg,image/gif;q=0.2,text/css,*/*;q=0.1' Which looks identical to me... Am I going about this all wrong? Is there a way to tell if a browser can deal w/flash before sending it out? _________________________________________________________________ MSN Photos is the easiest way to share and print your photos: http://photos.msn.com/support/worldwide.aspx

Handling exceptions in dtml
by Sven Rudolph 30 Aug '02

30 Aug '02

Hello all, I have a question about handling exceptions in dtml. The usual way to do this is: <dtml-try> <some_code> <dtml-except> <some_code_in_case_of_any_exception> </dtml-try> What I want to do is let <some_code_in_case_of_any_exception> tell what the exception was. I tried <dtml-var error_type> and <dtml-var error_value> in <some_code_in_case_of_any_exception>. What I want to now is, is there a way to get an even more detailed error message at this point? Thanks in advance Sven -- Sven Rudolph, Programmierer GermanMedicalServices.de GmbH Unter den Eichen 5, 65195 Wiesbaden Tel.: 06 11 / 97 46 25 2
