whoops. sorry...i forgot to mention the revision i'm in (1.10.2, ExternalMethod 1.3). i'll see if i can find the appropriate code in 1.11.x -----Original Message----- From: Tony McDonald [mailto:tony.mcdonald@ncl.ac.uk] Sent: Monday, May 10, 1999 7:15 AM wolf said: >i was able to patch it by replacing line 255 in ExternalMethod.py with: > >----- > if (type(error_type) is type('')) and (lower(error_type) in >('redirect',)): >----- Ah, that might explain it. Only problem is that I'm using Zope-1.11.0pr1 and there aren't enough lines in ExternalMethod.py

Here's a hint, Put a ZClass in another ZClasses method tab, create a constructor, and hange munge the Add select box for your Parent ZClasses manage_main (or whatever). -Michel > > -- > Martijn Pieters, Web Developer > | Antraciet http://www.antraciet.nl > | Tel: +31-35-6254545 Fax: +31-35-6254555 > | mailto:mj@antraciet.nl http://www.antraciet.nl/~mj > | PGP: > http://wwwkeys.nl.pgp.net:11371/pks/lookup?op=get&search=0xA8A32149 > ------------------------------------------ > > _______________________________________________ > Zope maillist - Zope(a)zope.org > http://www.zope.org/mailman/listinfo/zope > > (For developer-specific issues, use the companion list, > zope-dev(a)zope.org - http://www.zope.org/mailman/listinfo/zope-dev ) >

Wierd permissions problem
by Howard Clinton Shaw III 10 May '99

10 May '99

Well, I mentioned this once before, and got no response, but I've explored it just a bit more, so I thought I would bring it up again. If I have a user in a subfolder, with a role that has every permission set, just like the manager role, he cannot access images. He can add and delete them, but if he clicks on them, he cannot access the image's manage_main screen. If I give him the manager role, with exactly identical permissions (and every level between has permissions set to acquire, on EVERY permission) then he can view the manage_main page! What is the cause of this? -- Howard Clinton Shaw III - Grum St. Thomas High School #include <disclaimer.h>

Jay, Try . There was an excellent posting in the archives about all the possibilities with the user object. Also read the files in the AccessControl folder inside Zope/lib/python. -- Jason Spisak webmaster(a)mtear.com

Problem Running Zope as a win32 Service
by Aaron Gillette 10 May '99

10 May '99

Hi All, I'm new to Zope. I recently installed Zope as a win32 service running under IIS 4.0(I'm running it as an exe in the cgi-bin directory of my web site). Everything seems to be working fine. I'm able to bring up the management screen, change object properties, etc. My question is, how do I "publish" the changes that I've made in Zope. That is, Zope seems to be a completely separate entity from the rest of my site. How do I configure Zope to process requests for, say, www.foobar.com/index.html when the Zope exe resides in www.foobar.com/cgi-bin/zope.exe ? I've searched the documentation without luck. any help will be greatly appreciated. Aaron Gillette

adding a line to a property using DTML
by Martin Dougiamas 10 May '99

10 May '99

It's the simple things that stump! Is it possible in DTML to easily add a line to a property of type 'lines' ? (I can do it using external methods but would rather not) ie something like:   keeps giving me "Error value: illegal argument type for built-in operation" Cheers, Martin

ZClasses derived from ObjectManager and Factories
by Martijn Pieters 10 May '99

10 May '99

This is more a question for DC than for the list: Will it be possible in the future to limit in what places users can add ZClass instances? I have one ZClass derived from ObjectManager, let's call it Container, and another called Element, a simple object, and I want to be able to add instances of Element to Container, but not to any other ObjectManager derived objects (including Folders). Right now, this means I have to provide an alternative to manage_main.. -- Martijn Pieters, Web Developer | Antraciet http://www.antraciet.nl | Tel: +31-35-6254545 Fax: +31-35-6254555 | mailto:mj@antraciet.nl http://www.antraciet.nl/~mj | PGP: http://wwwkeys.nl.pgp.net:11371/pks/lookup?op=get&search=0xA8A32149 ------------------------------------------

External methods and images
by Tony McDonald 10 May '99

10 May '99

Hi, I have an external method that gets an image from a directory (ie the image is *not* in the ZODB) and then adds the correct headers to display it to the browser. Trouble is, it don't work. The code is... def img(self, RESPONSE, src): import os img_dir = '/home/nnle/zope/Zope-1.11.0pr1-src/Images' img_name=os.path.join(img_dir, src) # Determine the ad type img_type=image_type(img_name) # Open ad file, using 'rb' to open it in binary mode! img_file=open(img_name, 'rb') img_data=img_file.read() img_file.close() # Set the content-type of the response RESPONSE.setHeader('content-type', img_type) return img_data The DTML that calls it is <img src=''> (normally the image name will not be there - it is got from another external method) and the traceback is  I've tried <img src=''>, and I get  anyone got any ideas? This is driving me batty.
