object shortcuts
by David Bear 11 Oct '04

11 Oct '04

I was hoping to place some short cut object in the root of my zope site that point directly down into certain folder within the plone site. Silva has something called a shadow. I was wondering if there is something that can be used generally to create a 'rewrite' object. For example: if my zope plone site looks like this \ \standardzopestuff \standardzopestuff\plonesite\members\ploneuser\coolstuff I would like to have a url like \coolstuff that maps straight into the ploneusers folder. I don't know what to call this.. in apache this would be a rewrite. Is there a zope product that does something like this? -- David Bear phone: 480-965-8257 fax: 480-965-9189 College of Public Programs/ASU Wilson Hall 232 Tempe, AZ 85287-0803 "Beware the IP portfolio, everyone will be suspect of trespassing"

preload/sync users from NIS ?
by Gilles-Eric DESCAMPS 11 Oct '04

11 Oct '04

Hi, I'm trying to deploy Zope-2.7.2/Plone-2.0.4 for an intranet running on a clone of RedHat Enterprise Linux 3 u3. I searched but could not find any script that would preload / synchronize the Zope/Plone users with the NIS (/etc/passwd) users. I've tried exUserFolder, but could not get it to work. Plus from the documentation, I understood that it does not support creating all/some of the NIS users by itself. (ie: a user has explicitely request creation of a new account for the passwd sync to work) I'm looking to import all my 3000 NIS users (login/passwd) into Zope. Is there such a script ? Is there documentation on how to write one ? What do people that run an intranet (with an enterprise database of login/passwd) use ? I'm looking for a solution where, to access the intranet pages, a user just has to login using his(her) usual login/passwd. Thanks for your help. -- ged.

Default new document
by David Chandek-Stark 11 Oct '04

11 Oct '04

By default, a new file created in Zope (not CMF) via WebDAV or FTP is a DTML document. I assume there is a way to change this, say, to a Zope Page Template? I am investigating integrating Dreamweaver's native templating with ZPT's in Zope.

I'm trying to format a Date retrieved from MySQL, but while I can print the date as it is I can't access any of the methods, so no strftime() and no day() etc I get a 'not allowed in this context' exception so: <i tal:content="python:item.data"></i> is ok but: <i tal:content="python:item.data.day"></i> causes Zope to ask for authentication Zope 2.7.2, Python 2.3.4 here any hint would be appreciated thanks massimo

ZCataloging without ZClasses
by massimop＠users.berlios.de 11 Oct '04

11 Oct '04

Hi, being the use of ZClasses frequently discouraged, I was wondering if there is any way to dynamically add or reindex objects in a ZCatalog or if there is any alternative. thanks massimo

Yes, I've actually missed that. I suppose I was looking for a file_streaming implementation. I think ExternalFile could benefit from implementing it. I'm actually contemplating fixing it, although I'm not so pleased with the user interface of ExternalFile and I would like to limit the access to just a few directories on the file system from the Zope Configuration preferably. I might rewrite the complete product.

Problems with Zope and Squid...
by Braun Brelin 11 Oct '04

11 Oct '04

Hello all, I'm having some problems trying to get Zope to work correctly with my Squid proxy cache. Specifics: I'm running Zope 2.7.2 and Plone 2 on a Red Hat Linux 9 box. I'm using squid 3 and squidguard to handle the URL rewriting. The rewriting rule in the SquidGuard.conf file looks like this: dbhome /var/lib/squidguard/db logdir /var/log/squid acl { default { redirect http://localhost:9080/VirtualHostBase/http/localhost:80/dms/VirtualHostRoot… } } Where dms is the name of my plone portal. The error I'm getting from the Z2.log is: 127.0.0.1 - Anonymous [11/Oct/2004:17:49:17 +0100] "GET http://localhost/ HTTP/1.0" 404 1512 "" "Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7) Gecko/20040616"127.0.0.1 - Anonymous [11/Oct/2004:17:49:18 +0100] "GET http://localhost/p_/ZopeButton HTTP/1.0" 304 308 "http://localhost/" "Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7) Gecko/20040616" Why am I getting a URL rewritten to look like localhost/p_/ZopeButton? I'm getting the standard error page from zope: Site Error An error was encountered while publishing this resource. Resource not found Sorry, the requested resource does not exist. Check the URL and try again. Resource: no default view (root default view was probably deleted) Anyone know what's going on here? Thanks, Braun Brelin

I've looked at the code of the latest release of ExternalFile and I can't find the new streming interface being used at all? I'm also intrested in this, but I haven't had the time to as anyone about it, yet. Regards, Johan PS.

RE: [Zope] picture as parameter for an external method / thumbnail
by VIGNAUX Philippe 11 Oct '04

Hi You are right Dragos ! Your code is working fine with the read() method and the picture is well provided to the external method. Many thanks to you and Tino. I have now added some extra code in the external method to create a thumbnail from the picture. But unfortunately the same "exceptions.assertionError" happens again :- ( ( If i'm only leaving the first real code line (getattr), the error already appear. Creating a thumbnail seems to be something tricky as another user of zope community had also somme problems (other errors message) with that matter this morning... Any hint ? Anyway thanks for the help ! def makethumbnail(self, original_id): from PIL import Image from StringIO import StringIO import os.path # create a thumbnail image file original_image=getattr(self, original_id) original_file=StringIO(str(original_image.data)) image=Image.open(original_file) image=image.convert('RGB') image.thumbnail((size,size)) thumbnail_file=StringIO() image.save(thumbnail_file, "JPEG") thumbnail_file.seek(0) # create an id for the thumbnail path, ext=os.path.splitext(original_id) thumbnail_id=path + '.thumb.jpg' # if there's and old thumbnail, delete it if thumbnail_id in self.objectIds(): self.manage_delObjects([thumbnail_id]) # create the Zope image object IN MY OWN LOCAL FILE SYSTEM self.phvfs.manage_addProduct['OFSP'].manage_addImage(thumbnail_id,thumbnai l_file,'thumbnail image') thumbnail_image=getattr(self, thumbnail_id) # set the 'originial_id' property thumbnail_image.manage_addProperty('original_id', original_id, 'string') REGARDS Ph. -----Original Message----- From: Dragos Chirila [mailto:d.chirila@finsiel.ro] Sent: lundi 11 octobre 2004 17:20 To: zope(a)zope.org; VIGNAUX Philippe Subject: Re: [Zope] picture as parameter for an external method Hi I just simulate your situation and it works great.
