by Jens Vagelpohl 26 Feb '06

26 Feb '06

The CMF developer community and Zope Corporation are pleased to announce the release of version 1.6.0 of the Zope Content Management Framework (CMF). This release marks the first stable release in the CMF 1.6 series and should be suitable for production use. What is the CMF? The Zope Content Management Framework provides a set of services and content objects useful for building highly dynamic, content-oriented portal sites. As packaged, the CMF generates a site much like the zope.org site. The CMF is intended to be easily customizable, in terms of both the types of content used and the policies and services it provides. What's new in this release? The CMF 1.6 release series acts as an intermediary between the stable 1.5 series and the 2.0 feature release. It allows developers an easy upgrade path from 1.5 and the ability to take advantage of one of the most interesting features from the upcoming major feature release, GenericSetup. Where do I get it?

want to use external script to read a text-file and image in database and modify REQUEST
by Allen Huang 25 Feb '06

25 Feb '06

Hi I want to use external methods to read a text file and image in database and modify the REQUEST my code looks like this varible ----------------------- def imageSetup(self, imageID, dataID, REQUEST): import PIL.Image from StringIO import StringIO # Get the original image and data in memory. image=getattr(self, imageID) imageData=getattr(self, dataID) imageFile=StringIO(str(image.data)) imageDataFile=StringIO(str(imageData.data)) # open image and data file im = PIL.Image.open(imageFile) tfw = open(imageDataFile, "r") # assign data coordinate and image size to variables imX,imY = im.size() rX=float(tfw.readline()) tfw.readline() tfw.readline() rY=float(tfw.readline()) mnX=float(tfw.readline()) mnY=float(tfw.readline()) mxX=mnX+imX*rX mxY=mnY+imY*rY # assign variables to REQUEST REQUEST.set('resX', rX) REQUEST.set('resY', rY) REQUEST.set('minX', mnX) REQUEST.set('minY', mnY) REQUEST.set('maxX', mxX) REQUEST.set('maxY', mxY) REQUEST.set('pixelX', imX) REQUEST.set('pixelY', imY) -------------------------------------- but all I get is this zope coercing to Unicode: need string or buffer, instance found and the REQUEST variable is unchanged I'm still new to external scripting so I don't know what the problem is (and I think there is a lot of it here) so, could someone help me out?? --------------------------------- Yahoo!

How can I put something in a session from ZPT? I've tried: <div tal:define="session/foo request/foo"> <div tal:define="foo python:session['foo']=request['foo']"> Do I really have to write a python method just to assign a single value? Robert (Jamie) Munro

image processing site quidance...
by Nicolas Georgakopoulos 24 Feb '06

24 Feb '06

Hello Zopistas, I need a little guidance for a site that must make image processing on the fly. Users should be able to upload image files and after some pixels manipulation they should see the image preview after the changes and download it. I have installed PIL successfully for that reason (thanks to smiley Chris) so I can use it as an external method. I have thought to do this implementation uploading the file to the ZopeDB and change it there or should the file be uploaded in the local file system ? either way , what should I know so I can do that ? thanks in advance.

CMFExternalFile and huge ZODB pickles
by Pawel Lewicki 24 Feb '06

24 Feb '06

Hi, I have a problem with one Zope application and have no clue what's going on. The problem is with one ControlledPage that creates CMFExternalFiles. It seems that each file is somehow included in ZODB pickle so Data.fs grows very fast. Only packing helps. The side effect is that transaction takes quite a long time so conflicts are very common. I tried to recreate the environment on the other machine and everything was fine despite the fact that I used all the same products. The only difference was that original app was running on Linux and I did it on Windows. Any clues? Products used: - ExternalFile 1.2.0 - CMFExternalFile 0.5 - Plone 2.0.5 - Zope 2.7.6 BTW, how do you distinct read and write conflicts in event.log? I only have INFO(0) ZODB conflict error at...

Possible to run Zope on a shared host?
by Marty McFly 24 Feb '06

24 Feb '06

Hello, I've just tried to install zope on a shared host which is run by an Apache server. I have seen on the net, that there are 3 possibilities to run Zope together with Apache: rewrite_rules, ProxyPass and FastCGI. As far as I've seen, all of these 3 modules are already installed on the server. However, I think that you need to have root/superuser/...-privileges in order to use one of these methods, right? Unfortunately, I don't have any of those privileges... I only have write-access to my personal home-directory. Do you have an idea what I could do instead?

limiting view access to acl_users
by gf 24 Feb '06

24 Feb '06

Hi, I am relatively new to Zope and have a question regarding acl_user folders. I am trying to prevent 'view' access to an acl_users folder that I have created in a non-root area of my website. I have used the management interface Security tab to uncheck the 'Acquire permission settings' for the 'View' Permission and have enabled View for the Manager role only. I have taken the same actions for my root acl_users folder as well. When I browse to http://mysite/myfolder/acl_users, I am presented with a view of the index_html file contained within myfolder, with the <dtml-var title_or_id> 'output' indicating that it is 'User Folder'. Why is acl_users making use of the container's index_html? Is there a way to limit even View access to this folder? Thanks. -g
