As I mentioned in an earlier letter I'm new to Zope and > I find it very hard to get an overview of all the different modules If you are new to Zope you should drop DTML like a hot potatoe and start doing your logic in python and your presentation in ZPT -- strictly parted. Also don't bother too much with implementing stuff with TTW means ("through the web" - the stuff you do from the ZMI). Better start doing filesystem python products. Read for example http://zopewiki.org/ZopeStarter - including the link to the "new" tutorial from upfrontsystems. The ZopeStarter page is a 5 minute read, but has good pointers to stuff that will get you started in the right directioin. Regards, Sascha

Cookie Crumbler/Authentication Question
by Palermo, Tom 19 Apr '06

19 Apr '06

All, I am working on a site that uses CookieCrumbler for the authentication. Part of this site allows a user to change their password via this line: userfolder.manage_users(submit='Change', REQUEST=user_info). This works fine except after changing the password, the user is no longer authenticated and an Unauthorized exception is raised. Is there anyway to automatically keep the user logged in or re-authenticate them. Thanks, Tom Palermo

Custom 404 - Resource not found
by Andy Yates 19 Apr '06

19 Apr '06

Is there a way to customize the Zope 404 error page? Site Error An error was encountered while publishing this resource. Resource not found Changing standard_error_message does not seem change this error page. I need to do this inside Zope or via the apache front end which talks to Zope through mod_rewrite/proxy and Virtual Host Monster. Thanks! Andy

Re: [Zope] Getting www.domain.com:8080/manage to go through Apache
by michael nt milne 19 Apr '06

Ok, good to know that. So if I get this right I add in _vh_manage to the VirtualHostRoot in Zope which will cause /manage/ to be appended onto the all the URLs within Zope. The correct pages will still be served and the Apache re-write rule will be satisfied...

Re: [Zope] DELETE Objects
by Erik Billing 18 Apr '06

18 Apr '06

Ok. Thanx. But why is it like this? I imagine that deleting an object in a folder where I do not have permission to delete every object, or the folder itself, is a quite common task. Using the manage_delObjects and a proxy really feels like I'm fighting the zope security instead of getting support by it. Or am I thinking wrong in the first place? What I really want to do is letting users answer a question object and the answers should be stored somewhere. A user must later be able to change or remove his answer, but of course not the answers of any other user. I place all answers objects belonging to a certain question in one folder, and I have the previously mentioned situation. I know it is not that much of a problem to use a proxy, but if I can change my design in some way so can avoid the proxy I imagine that would be better. /Erik On 4/18/06, Andreas Jung <lists(a)zopyx.com> wrote: > > > > --On 18.

The Plone people have an "epidoc" documentation online (I do not have the url at hand, you have to search for it). Like any documentation generated automatically from the source (this is valid also for Java documentation), it is complete but contains more details than you might be interested in. -- Dieter

Thanks alot. I didn't realise you could do this within the RewriteRule directive. Cheers.

Some installation glitches
by Dennis Allison 18 Apr '06

18 Apr '06

64-bit machines (dual dual-core AMD Opteron) First: Configuring Zope installation Using Python interpreter at /usr/local/bin/python2.4 /usr/local/bin/python2.4 install.py -q build Dependencies/ExtensionClass-Zope-2.9.2/ExtensionClass/_ExtensionClass.c: In function `PyExtensionClass_Export_': Dependencies/ExtensionClass-Zope-2.9.2/ExtensionClass/_ExtensionClass.c:768: warning: cast from pointer to integer of different size /usr/local/bin/python2.4 install.py -q build /usr/local/bin/python2.4 install.py -q install --skip-build --home "/usr/local/src/zope/Zope2.9" _ExtensionClass is not 64-bit clean. I believe the warning can be ignored. When I install Zope 2.9.0 on a 64 bit machine the path to the system is .../Zope/lib64/python/... but with Zope 2.9.2, also on a 64-but machine the path to the system is ...Zope/lib/python/.... Why the change? --
