What happens top me is that <dtml-var my_field> is rendered as None when the empty string is encountered. Maybe the None answer is default I don't know. However I want it to be rendered as 0 and the NVL returns 0.0 and and I can't emliminate the trailing .0 -- Stig-Arne Nordin

RE: [Zope] Zope install on Redhat
by Joshua Penix 05 Sep '01

How did you install the Python 2.1? Did it come from RPM? If not, that's okay - you can force the Zope RPM to ignore its perceived need for the python2 RPM: rpm -ivh --nodeps zope.i386.rpm (forgot exact RPM name) Alternately, you can get the python2 RPM from python.org and install it - then the Zope RPM should be happy.

Re: [Zope] Zope management screens and OmniWeb (on OS X)
by Dominique.Dutoit＠cec.eu.int 05 Sep '01

05 Sep '01

Same problem here. But I think that the problem is elsewhere because I don't have any problem to manage my personal folder on zope.org with OmniWeb. Maybe the problem is authenticating an user when there is a port number in the URL. Or the way zope.org does the authentication is more friendly that the authentication window. I have tried to run zope on a port 80 but Python refused to bind the port and I'm sure that Apache is not running. It seems that Mac OS X protects some resources. By the way, iCab has exactly the same problem and yet, it works with the personal folder. Dominique

It allows you to specify what types can be added to your folder. Maybe if you have no sub-objects selected thoses functions will not be available. _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com/intl.asp

Subtracting 2 datetime objects
by Gitte Wange 04 Sep '01

04 Sep '01

Hello, I need to figure out a start time for an object from two other start times. I have made myself a little Python Script inside Zope to test this (because I don't know exactly how this works). So I created myself two variables: d1 = DateTime('14:55').timeTime() d2 = DateTime('15:00').timeTime() time = d2 - d1 return DateTime(time).Time() This gives me an output of 01:05:00 when I expected 00:05:00. what is it I don't get ?? TIA, Gitte Wange

Problem with ThumbNail Image
by Sylvain Boureliou 04 Sep '01

04 Sep '01

Hi all I would like to create a thumbnail from a jpeg file. Here is the fonction i use : def ThumbNail(self): import Image, os, sys texte = "ok" img = Image.open("essai.jpg") img.thumbnail((50, 50)) img.save('essaiThumbnail.jpg', "JPEG") return texte The file "essai.jpg" is in the Zope directory. It works very well from the Python command line, but it doesn't work when i use it in an external method. Zope finds the file but this error is raised : (i'm using Zope 2.4 win32 - Python 2.1 - PIL 1.1.1) Error Type: IOError Error Value: cannot identify image file .... File C:\Program Files\zope\Extensions\ScriptsEpinet.py, line 24, in ThumbNail File c:\python21\pil\Image.py, line 902, in open IOError: (see above) Thanks very much for help. Sylvain

Problems in updating ZClass instance property sheets
by Per Hörnfeldt 04 Sep '01

04 Sep '01

Hi, In general, the problems concerns updating properties in propertysheets belonging to certain ZClass. We have a dtml-document called "UserRegistration" and a python script called "registerUser". The dtml doc is a form that is filled in with user data. Then the script is called to proccess the data. We are using the standard acl_users for storage of user data. Because we want to have some additional information in the user object (and the acl_user can not be extended with more properties), we are using a product called "userinfo folder" found on www.zope.org. For each acl_user, there will be a zclass instance of UserInfo class in the userinfo folder. So when acl_users.manage_user(...) is run, a userinfo for this object will also be created. The problem appears when we want add the additional information in the userinfo object with the method manage_editProperties. The property belongs to a propertysheet. We get the following error message "you are not authorized to access propertysheets" even though our user is a manager with all rights. And the funny thing is that if we restart the server it executes one time but following attempts fail. The code that breaks looks like: Note that the data is in the request ======== # create the user and save user data context.acl_users.manage_users('Add', request) # save the additional properties for the user in its userinfo instance for object in container.data.user_info.objectValues('UserInfo'): if object.getId() == request.name: object.propertysheets.get('student').manage_editProperties(request) // student is the propertysheet name, it breaks here ======== We are running: Zope 2.4.1 beta 1 UserInfoFolder-1-0-0 http://www.zope.org/Members/did/UserInfoFolder on Windows NT ZClass UserInfo (UserInfo.zexp) and script and DTML-doc (createUser.zexp) are attached. hope you guys can help us. A UserInfoFolder data.user_info instance must be able to aquire in order to be able to execute the code. The entry point is the "userRegistration" DTML Document. /Johan Parmar and Per Hörnfeldt <<createUser.zexp>> <<UserInfo.zexp>> _ _ _ _ _ __________________________ _ _ _ _ _ - - - - ReachIn ---------------------- - - - - ¯ ¯ ¯ ¯ ¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯ ¯ ¯ ¯ Per Hörnfeldt Reachin Technologies AB Årstaängsvägen 24 117 43 Stockholm Sweden Direct: +46 (8) 556 766 19 Phone: +46 (8) 556 766 00 Fax: +46 (8) 556 766 01 mailto:per.hornfeldt@reachin.se Web: www.reachin.se
