Hello, I'm working on a chain menu which displays the following: Previous | Current objectid | Next Previous and Next are hyperlinks. When I have peer objects (brothers and sisters) it is working fine. But when I have no peers, I get the following error: File /usr/lib/zope/lib/python/Products/PageTemplates/ZRPythonExpr.py, line 49, in __call__ (Info: chain[0]) File Python expression "chain[0]", line 2, in f File /usr/lib/zope/lib/python/AccessControl/ZopeGuards.py, line 90, in guarded_getitem TALESError: Sorry, an error occurred This is my code (from a Zope Page Template): (thanks David) <span tal:define="chain here/list_chain"> <a href="#" tal:condition="python:chain[0]" tal:attributes="href python:chain[0].absolute_url()">Previous</a> <b tal:content="python:chain[1].title_or_id()">Sample title</b> <a href="#" tal:condition="python:chain[2]" tal:attributes="href python:chain[2].absolute_url()">Next</a> </span> This is the list_chain method that I call in the above ZPTemplate: def list_chain(self, sortkey='id'): """return (previous,current,next) objects """ NewsTuples = [] # a list of (sortkeyvalue,object) tuples for item in self.REQUEST['PARENTS'][1].objectValues('News'): if item.inDateRange(): NewsTuples.append( (getattr(item,sortkey),item) ) NewsTuples.sort() (previous,current,next)=(None,None,None) for (sortkey,object) in NewsTuples: if current is not None: return(previous,current,object) elif object.id == self.id: current=object else: previous=object if previous is not None: return(previous,current,next) Can someone help me with this problem?

CMF Complex Document issue
by eric.n.dunn＠bankofamerica.com 31 May '02

31 May '02

I'm using CMF 1.2 on my ZOPE 2.5 (Debian) site. We have many documents (PDF, MSWORD, MSEXCEL) to transfer from a shared drive and want to upload them with ZipFolder. ZipFolder works great but I want to have CMF users/members be able to see ZipFolders in there CMF Desktop. CMF Complex Document looks like the Product I need but can't get it working on my site. Any ideas? Eric Dunn

ZIPFolder Fix Ignore Files w/ spaces
by eric.n.dunn＠bankofamerica.com 31 May '02

31 May '02

This was it! Thankyou very much! Couldn't find the code in "ZipFile.py" since "ZipFolder 0.2.2" doesn't have that specific file by default. -rw-r--r-- 1 zwww zwww 6550 May 31 05:41 ZipFolder.py -rw-r--r-- 1 zwww zwww 24360 Apr 6 2001 zipfile152.py Looked for it in "ZipFolder.py" and found it. Code change to "ZipFolder.py": # check zip file names for: # filenamepattern=re.compile(r'[A-Za-z0-9][\w\_\-\.]*$') <--- OLD filenamepattern=re.compile(r'[A-Za-z0-9 ][\w\_\-\. ]*$') <--- NEW Tested and worked perfect the first time. Files w/ spaces not ignored anymore and rendered just fine in presentation layer. You the man!!! Thanks again Eric Jens Quade <jq(a)jquade.de> on 05/30/2002 03:25:14 PM To: Eric N.

Zipfile refuses to import files with strange filenames. The pattern is a bit strict... If you want to import files with spaces, find the following lines in ZipFile.py: # check zip file names for: filenamepattern=re.compile(r'[A-Za-z0-9][\w\_\-\.]*$') and change it to: # check zip file names for: filenamepattern=re.compile(r'[A-Za-z0-9 ][\w\_\-\. ]*$') (note the added blanks) jens

Adding ZPT in init method product
by Nico de Boer 31 May '02

31 May '02

Hello, Thanks for your ideas. I managed to solve the problem!!! This is the code: from Products.PageTemplates import ZopePageTemplate self._createZPT(self, 'ZPT_id', 'title', 'content') def _createZPT(self, parent, id, title, content): """Add a PageTemplate to the News product""" parent._setObject(id, ZopePageTemplate.ZopePageTemplate(id, text=content)) parent._getOb(id).pt_setTitle(title) Maybe you can use it? Thanks again. Greetz Nico

remove square brackets in dtml-var
by Joshua Newman 31 May '02

31 May '02

My <dtml-var mail_group> renders as: [mail1(a)here.com, mail2(a)there.com] I am trying to use dtml-var to insert multiple email addresses into a sendmail form but when I use: to: <dtml-var mail_group> I get: Error Type: SMTPRecipientsRefused Error Value: {} Multiple addresses work fine if entered as: to: mail1(a)here.com, mail2(a)there.com but I get the identical error if I try to: [mail1(a)here.com, mail2(a)there.com] Is there an easy way in dtml to shed the '[' and ']' and keep the ',' or do I have to write a python script? It's not that the python is too terribly hard, I just want to do it simply, if possible. (and it's been a long day and it's hot in chicago w/o a/c) Thanks again, joshua

EuroPython2002
by Tom Deprez 31 May '02

31 May '02

Last hours for early bird registration at EuroPython 2002 ! Perhaps we should have announced you sooner that we are now well over 100 attendees. That's already a good band to enjoy a great conference. It started pretty quick with subcriptions during minutes after the registration page was online, then we had a frightening slow down, but these last days have seen a steadily growing rate. Now, I'm really convinced you will miss a big event if you stay home while we will be drinking belgian beer altogether. :-) We will have an O'Reilly competition, with lot's of books to win. We will have the best developpers and the best sandwiches of the world. We will have nice weather and lots of discussions about Python future (EuroPython, EuroZope, PBF, ...) What will be missing ? You ? Oh no ! http://www.europython.org/Registration See you soon.

FYI: German Zope User Group (DZUG)
by Maik Jablonski 31 May '02

31 May '02

this mail announces the foundation of the German Zope User Group (Deutsche Zope User Group / DZUG). -------------------------- http://www.dzug.org/ hi to all german-speaking Zope-users! nach etwas hin und her haben wir uns entschieden, eine "Deutsche Zope User Group" (DZUG) ins leben zu rufen... ihr vornehmliches ziel soll darin bestehen, den persönlichen kontakt zwischen deutschsprachigen Zope/Python-Usern auf nicht-kommerzieller basis zu fördern. wir gehen davon aus, daß für viele ein erhebliches kommunikationsbedürfnis rund um Zope und Python besteht, aber nicht alle über die finanziellen ressourcen verfügen, die großen Zope/Python-Events zu besuchen... zumindest geht es uns so... deshalb wollen wir regelmäßig kostenlose DZUG-Treffen veranstalten. das erste treffen soll am 31. august in bielefeld steigen. die idee ist ein nettes beisammensein zum kennenlernen und erfahrungsaustausch mit nebenbei ein paar würstchen auf dem grill und nem bier in der hand (das sind die versteckten (selbst-)kosten...;-)). wir planen, das erste DZUG-Treffen unter ein motto zu stellen: "ZOPE in Deutschland ins Rollen bringen oder - Wie migriere ich meine bestehenden Server nach ZOPE?" dieses thema bietet evtl. die chance, sowohl newbies als auch oldies miteinander ins gespräch zu bringen. natürlich sind wir auch für ganz andere themen offen. wir haben deshalb auf http://www.dzug.org/ zur vorbereitung des treffens eine mailingliste und diskussionsforen eingerichtet und hoffen auf anregende beteiligung. sehr schön wäre es auch, wenn der eine oder andere bereit wäre, einen kleinen beitrag in form eines kurzberichts beizusteuern, um so der diskussion etwas linie zu geben. kuchen wären als beitrag allerdings auch nicht schlecht...;-) soviel zum anrollen... viele grüße, maik jablonski -- maik jablonski \ -;~~;- / www.dzug.org universitaet bielefeld > (@@) < www.zfl.uni-bielefeld.de zentrum fuer lehrerbildung / RUN \/ GNU \ www.sachunterricht-online.de
