Yes, the most important difference is that CMF and Silva are content management systems, and I'm focussing my efforts in to use Zope as a bussiness applications development framework. I use adapters to apply a Model View Controler pattern. I've diveded my development into: 1) Types. Basic objects with its model methods and its unitary views. For instance, a Folder with its creation and modification methods and forms, but without any logic (neither navigation between methods, REQUEST doesn't appear here). 2) Applications. Each application acts as a controller of used Types, and also can add some custom views. This functionallity is added throught adapters. So, the application can decide in which framework should appear the add_folder_view, where its submit should be sended, and what should be done after adding. This way, same object could be used from various applications with no problems. All the logic and navigation is decided in each application.

[Zope-dev] restrictedTraverse doesn't give the good container.
Hi, Today, I have this situation: Under my root Zope Site, I have this hierachy: - FolderA ---FolderB FolderC -FolderC What is interesting is that a folder named FolderC appears under another folder named with the same name. Assuming the path is the good one (path=.../.../FolderB) I try : herenow = context.restrictedTraverse(path+'/FolderC') - OK herenow = herenow.restrictedTraverse(path+'/FolderC') - OK Now I just delete the last FolderC, I have: - FolderA ---FolderB FolderC I try : herenow = context.restrictedTraverse(path+'/FolderC') - OK herenow = herenow.restrictedTraverse(path+'/FolderC') - OK BUT here I'm just not where I think to be, just because of the acquisition !!! I have no time to have a look on this, but anyone have seen this problem and resolved it? Sincerily PS -- Oreka ! Nous sommes l'internet moins cher !

[Zope-dev] TypeErrors during 'make test'

I'm not sure what the actual cause of the failure is. The symption is that validate() is being passed a single PermissionRole object as its roles argument. validate() expects roles to be a sequence and fails with a TypeError iterable argument expected when it sees the PermissionRole. What isn't clear to me is if the argument should be a Python sequence that contains a PermissionRole or if it should be an imPermissionsRole, which is a sequence. I don't understand the code well enough to know which of these is more likely.

[Zope-dev] 2.7.0 corrupt Data.fs
I'm seeing changes to the ZODB getting lost on reboot. I think it's
because there are no fsync() calls being issued by Zope or even by
zopectl on stopping Zope but I can't be sure. I'm using
/instance/bin/zopectl {start|stop} for controlling Zope.
I added a sync command to my /etc/init.d/umountfs script (Debian
Woody) and this seems to have fixed the problem. I know postgresql
syncs to disk for every transaction by default, does Zope?

ZODB does, as you can see in your installation's FileStorage.py
FileStorage._finish method.
Which version of Python are you using? If you're using one of the early 2.3
releases, that would explain it; from the NEWS file for Python 2.3.2:
- A bug in the autoconf machinery meant that os.fsync was never
available.
2.3.3 should be used now.
