I have been getting an rfc1123 error on the site that I have been developing on for about a week now. I will get this error off of my main page (ie www.sitename.com:8080/) If I go to the manage resource, I am authenticated through a id/pw screen and from then on all is well. I have tried to debug myself but to no avail. If someone can suggest the error of my ways I would appreciate it. Zope Error Zope has encountered an error while publishing this resource. NameError Sorry, a Zope error occurred.

This is not a default attribute for any objects in zope. It looks like you got the idea for this code from the Zope site, which *does* use the attribute 'date' because we built a ZClass that all the objects subclass that defines 'date'. If you do not have a ZClass defining this attribute, then you probably want to change all the occourances of 'date' in your DTML to 'bobobase_modification_time'. -Michel

UserDB - error validating [Q]
by Bruno Mattarollo 22 Nov '99

22 Nov '99

Hi! I have set up the UserDB product in a temporary folder. I have set up all the ZSQL Methods that query the database. I have added user in the acl_users folder without problems, delete users, queried, etc ... But when I try to access a DTML method that resides in that temporary folder I get the following traceback: Traceback (innermost last): File /export/home/bmatt/iPersonal/lib/python/ZPublisher/Publish.py, line 214, in publish_module File /export/home/bmatt/iPersonal/lib/python/ZPublisher/Publish.py, line 179, in publish File /export/home/bmatt/iPersonal/lib/python/Zope/__init__.py, line 201, in zpublisher_exception_hook (Object: ElementWithAttributes) File /export/home/bmatt/iPersonal/lib/python/ZPublisher/Publish.py, line 151, in publish File /export/home/bmatt/iPersonal/lib/python/ZPublisher/BaseRequest.py, line 426, in traverse File lib/python/Products/UserDb/UserDb.py, line 289, in validate (Object: RoleManager) File lib/python/Products/UserDb/UserDb.py, line 284, in cookie_validate (Object: RoleManager) LoginRequired: (see above) I have uncheked the acquire permissions for "access content" and "view" for that document. Anyone has a clue on what's happening? thanks in advance. /B Bruno Mattarollo <brunomadv(a)ciudad.com.ar> --- Python Powered <http://www.python.org/psa/>

RE: [Zope] ZOPE VS. PHP, VIGNETTE ETC.

Zope scales to multiple arrays of servers with ZEO, which is a commercial addon. Without ZEO, you can get really good performance on one box, but you will hit a celing if your hardware can't handle it (This would happen with any platform). ZEO lets you connect multiple Zopes to the same object storage, so multiple processes on multiple machines can all access the same content. > 2. HOW FAST IS ZOPE?

It seems pretty quick but I'm not sure what > type of transactions are going on below the surface of the pages I'm > looking at. This is kindof an apples and oranges thing. PHP is probably faster for simple logic, but PHP does not provide nearly as much infrastructure (acquisition, full blown security system, XML object, Catalog, full text indexing, implicit transactional support, ORB style object publishing, FTP, XML-RPC, WebDAV etc...) as Zope does. PHP is just a language, not an application platform. > 3. HOW WELL DOES ZOPE WORK WITH MYSQL? > We have built some pretty serious backend with PHP and MySQL and I'd > love to be able to keep our database structure etc. Just fine. Note that MySQL does not support transactions. You must be very careful about that. > 4. HAS ANYBODY COMPARED ZOPE WITH VIGNETTE? > Some of our big clients have considered using Vignette. Seems Zope > has largely the same mission -- albeit with a lot of catch up to do. > Has anybody made a similiar comparison -- and if so do you have any > info or ideas to share? I don't think anyone has made a hard comparison, but we have stolen a few customers from Vignette. it sort of comes down to, who do you trust, us or them? Do you trust someone who gives you all the source code *and* has a community that helps you for free, or do you trust someone who will charge you thousands for a proprietary, close source system and you pay by the hour for support. As someone coming from PHP and MySQL, you should clearly understand the benefits Zope provides overy anything commercial. > 4. MIGRATING > What is the best way to migrate from a traditional web structure to > Zope? For instance do you have to rebuild and register all of your > objects with Zope through the web interface? Or can you upload files > and have them be recognized by Zope? You can upload content into Zope with HTTP, FTP, XML-RPC, and WebDAV. Content can also be loaded directly off the filesystem with an import script. -Michel

Missing views after creating a ZClass
by Michael Gutmann 22 Nov '99

22 Nov '99

Hello to all, I'm in a little trouble: I created a ZClass based upon DTMLDocument and reduced its number of views (I wanted to have just one sheet with some property fields and another view to display a method). Now every DTML Document on my site is missing the standard edit view (editing a DTMLDoc starts with the upload view). I'm using Zope 2.0.1 (binary release, python 1.5.2, solaris-2.6-sparc). Help greatly appreciated. Michael PS: There's a second problem, not as urging, but if I create a view in a ZClass that is connected with a method, this view isn't selectable on the top of the page. Bug or feature?

absolute_url in 2.1; clarification required
by Toby Dickenson 22 Nov '99

22 Nov '99

The behaviour of absolute_url has changed in 2.1 beta 2, relative to 2.0... Consider three sibling folders, a, b, and c. In 2.0, <dtml-var "a.b.c.absolute_url()"> would return "http://whatever/a/b/c", but in 2.1 it just returns "http://whatever/c". I guess the new behaviour is more consistent with it's name, but it does go against the docstring in 2.0: """Return an absolute url to the object. Note that the url will reflect the acquisition path of the object if the object has been acquired.""" Can someone confirm whether or not this change in behaviour was intended? Thanks, Toby Dickenson
