Re: [Zope-dev] Re: ZPatterns, ObjectDomain, UML and all that.....
Hi Itai, Good idea! I'll try to add this to the example. thanks! -steve Itai P.S. I've been struggling with a problem that might get Itai cleared up if you added it to the example: Itai Say you want to allow a user to add a ToDo from the Itai Deliverable screen (in addition to the existing menu for Itai selecting existing ToDos). You could either place a 'create Itai ToDo' form right there, using a UI snippet from ToDos, or Itai link to ToDos.addToDoForm. The problem is how to get the id Itai of the new ToDo into the deliverable. If you didn't store Itai todo_ids in Deliverable, instead calling Itai ToDos.getToDosForDeliverable(), there would be no Itai problem. Otherwise, you'd need a addToDoInterface in Itai Deliverable, which will call ToDos.addToDo, then add the new Itai ToDo id to todo_ids. Or, as a third option, you could pass a Itai method to ToDos.addToDo, and get it to call this method and Itai give it the new id. Itai What do you think? Want to tackle this in the example?

[Zope-dev] __bobo_traverse__, new ZCatalog and ZClasses
Zope 2.3, from cvs on 2000-12-24, patched with Chris P's latest ZCatalog stuff. I'm getting a bad interaction between ZClasses, ZCatalog and __bobo_traverse__. I have some ZClasses that are accessed via a container that implements __bobo_traverse__. The problem is that, although I can get to the ZClass instances by typing a URL into by browser, I get a security error when I try to get to them using restrictedTraverse. This causes a problem, as it means these instances cannot be catalogued in a ZCatalog, because ZCatalog now uses restrictedTraverse to get an object for indexing. The zope security validation gets stuck between not knowing for sure what the object's container is (according to comments from Traversable.py), and ZClasses not returning anything for __roles__. ZPatterns jargon paragraph: All this causes a problem if you want to use the ZPatterns idiom of ZClass DataSkins in a Specialist, catalogued using a ZCatalog. You can get around it by providing a __roles__ attribute using SkinScript. Is there some bug in the ZClasses __roles__ machinery? When does __roles__ get set on objects or classes anyway? I've found the description of what __roles__ are used for in the old Trinkets tutorial document. I think things have moved on a bit since then, though. Some relevant code snippets: Traversable.py t=get(object, '__bobo_traverse__', N) if t is not N: o=t(REQUEST, name) # Note we pass no container, because we have no # way of knowing what it is if (restricted and not securityManager.validate( object, None, name, o)): raise 'Unauthorized', name ZopeSecurityPolicy.py, line 123: # Try to get roles roles=getattr(value, '__roles__', _noroles) if roles is _noroles: # We have an object without roles. Presumabely, it's # some simple object, like a string or a list. -- Steve Alexander Software Engineer Cat-Box limited http://www.cat-box.net ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )

Hi Chris, Chris Withers wrote: *snip* PS: almost related, have you noticed how there's no way you can prevent Zope (other than hacking the source) from tacking the error message on the end of the HTML stream, even in production mode?

[Zope] Can't import objects ... is transparent folder still the reason ?
I have a problem importing objects (Yihaw Folder derived from Object Manager) on
2.2.4 and Transparent Folder (see traceback at the end).
Some months ago i had some similar problem with the first/removed Transparent
Folder version.
Is this same problem still there on Transparent Folder 0.3, or do i have to search the
problem elsewhere for a workaround ?
Any idea about a temporary workaround for importing such objects ? Because it will be
quite difficult to transfer things from developpement server to production server.
This is what Shane respond to this earlier problem. I was not able to see if TP0.3 is
now ObjectManager safe or not.
The TransparentFolders product patches ObjectManager so that objects
in transparent folders are searched. Unfortunately, the patch causes
the pickling mechanism to fail when ZODB pickles a class definition
derived from ObjectManager.
The
reason it fails is because the pickler doesn't recognize the new
__getattr__ method as a Python Method and tries to pickle it, which is
not possible. There is actually a way to solve that bug by patching
more Zope source, but I don't think that's the right solution.
The better solution will involve the same method SiteAccess uses to
change traversal behavior. Once SiteAccess has
settled, it should be easy to create a much improved
TransparentFolders. But for now, I have removed TransparentFolders
from the available products.
