re: Variable length tables
by garry saddington 31 Jul '03

31 Jul '03

I have a DTML method which displays the result of a ZSQLmethod in a table. The size of the table is determined by the number of records returned from the database and is variable. As the table grows in size i find that i lose all the html formatting below it resulting in links appearing beside the table instead of below it. I must be doing something wrong but i can't see it. Can anyone help? regards garry

Re: [Zope] Running a script at Zope startup

Thanks. I understand. The only "messy" solution I have thusfar is something like this: ...at bottom of module in product... def installConnections(): def install(): #1) get zope app object #2) loop through zope objects and create connections manually ... thread.start_new(install, ()) ThreadedAsync.register_loop_callback(installConnections) > Herman Lbh pna'g gehfg lbhe rlrf vs lbhe vzntvangvba'f bhg bs sbphf. -Znex Gjnva ----- Original Message ----- From: "Tino Wildenhain" <tino(a)wildenhain.de> To: "Herman Geldenhuys" <hgeldenhuys(a)gmsonline.co.za> Sent: Monday, July 28, 2003 4:38 PM Subject: Re: [Zope] Running a script at Zope startup > Hi Herman, > > Herman Geldenhuys wrote: > > Hi > > > > My problem is that the client connection must be started as soon as Zope > > starts up.

Programatically Adding 3rd Party Products?
by Edward Pollard 31 Jul '03

31 Jul '03

Since reinventing the wheel is a waste of my time, I'd like to use VarImage (seen here:http://www.zope.org/Members/terry/) for some of my dynamic image resizing needs. However, to do this, I need to be able to programatically create VarImage objects via Python scripts. I'm not entirely sure if I can do that. The attempt at cheap and easy solution, replacing calls to manage_addImage with manage_addVarImage, did not work). Is there something I need to do with the product to make its constructor usable in such a fashion? Thanks, Edward

Role Acquisition
by Andrew R. Halko 31 Jul '03

31 Jul '03

Hello all, I have a document that is a few folder layers deep in my site. I want to setup specific permissions for the document in that folder that don't acquire higher level permissions. From what I read, getting the security permissions with python on an object will get local roles, but will go high if they don't exist. I only want to know the local roles. Hope that is clear, thanks for any help! Andrew R. Halko

User Folder
by Robert Jean 31 Jul '03

31 Jul '03

Hello, I am looking for a User Folder that meets the following requirements: - login / logout with cookies - can easily associate additional data with users (e.g. phone#) - stable & well documented It would also be nice if adding SSL support was not too difficult to add. I have looked at mysqlUserFolder, but, being a beginner, I am a bit worried by the documentation that is not very polished. Any suggestion? Robert __________________________________ Do you Yahoo!?

Hello! I've install zope 2.7 which comes with OrderedFolder by default, but I can't understand how to use it. It doesn't have neither help nor readme file and looks just like ordinary folder. How do I order items in such folder? Eugene

cannot pack ZODB
by duchier＠ps.uni-sb.de 31 Jul '03

31 Jul '03

I am still a newbie and today I tried to pack my ZODB, but that's not working. Turning debugging on doesn't help much: 2003-07-31T15:18:36 ERROR(200) ZODB packing Traceback (innermost last): File /usr/share/zope/zope-2.6.1/lib/python/ZODB/DB.py, line 499, in pack File /usr/share/zope/zope-2.6.1/lib/python/ZODB/FileStorage.py, line 1496, in pack (Object: /var/lib/zope/zope-2_6_1/var/Data.fs) IOError: [Errno 13] Permission denied: '/var/lib/zope/zope-2_6_1/var/Data.fs' How is it possible that I can edit my ZODB just fine (through plone), but I cannot pack it? Apparently, it fails on attempting to open Data.fs for reading (i.e. file=open(name, 'rb')). The file is owned by user zope and group zope-2_6_1, with rw permissions for both. Any ideas? I am stumped! -- Denys Duchier - Équipe Calligramme - LORIA, Nancy, France

SimpleUserFolder Advice
by Michael Geddert 31 Jul '03

31 Jul '03

Hi List, I'm using SUF 0.9.0 on Zope2.6.1. I have to map the methods getProperty/setProperty of SUF's User-Object to ZSQL-Methods because we're using existing table structures from exUserFolders MySQLPropSource. Basically, I need to do a "user.getProperty('email')" (e.g. in a ZPT) to get a string with the current users email adress. This is working great. My Problem occurs when I want to get another Userobject from the Userfolder: uo=context.acl_users.getUser('anton') uo.getProperty('email') .. makes my Zope spin forever, my Browser keeps loading and loading, but nothing ever happens. Here's a snippet of what I added to User.py: def getProperty(self,key): parent=getattr(self,"aq_parent",None) context=getattr(parent,"aq_parent",None) # Check here later for context # Get Property from DB via ZSQL result=context.get_my_prop(myprop=key,myusername=self.name) return result[0][0] get_my_prop is a ZSQL Method and it works fine. I suspect "context" to break away within User.py at some point, maybe because the Object is not "wrapped" in Acquisition which would mean the ZSQL-Methods never get triggered (not sure exactly, somebody enlighten me plz). I also tried to let the Userfolder return User[dict].__of__(self) at some point, but that did not do the job either. Could someone point me to the right direction plz ? This is starting to get me frustrated Cheers, Michael
