My ZClass is based off Page Template and CatalogAware (vis a vis a CatalogAware wrapper for Page Templates! Is there any reason the developers are not making older types CatalogAware to save us this trouble and make the ZCatalog that much more usefull? I digress.) I had hoped the inheritance from Page Templates would have handled the required functions, but it does not. I can see where I might begin to move towards a solution in a Python Product, but not at all with a ZClass. It's a pity, as I'm so very close to being where I want with this. If anyone has any further thoughts on manipularing the inner workings of a ZClass, I'd find that tremendously helpful. In lieu of that, a primer on how to make a Python Product would be nice as it looks like I'll be working overtime... But, for the time being, I'll work with the ancient patch mentioned previously to see if I can incorporate the features I desire into Zope 2.6 Ed sean.upton@uniontrib.com wrote:

There are a few methods that you can create and/or override to make your objects behave in FTP/DAV friendly ways, which will likely need to be customized to work correctly with your class.

A good first question is what your ZClass is subclassing? If it is folderish, there are a few things that you can do to make it act more like a leaf-level object (i.e. SimpleItem-like). I've never done this in a ZClass, only in a python product, but you might need to define custom methods, like manage_FTPlist (override), manage_FTPstat, manage_FTPget, and PUT.

The biggest thing is that you need to make manage_FTPlist return a tuple with one element containing the stat info for one object, which tricks the FTP machinery into thinking this should be represented as a file/leaf object, and not as a directory to the FTP client.

This might work (likely as an external method?):

import marshal def manage_FTPlist(self,REQUEST): stat = marshal.loads(self.manage_FTPstat(REQUEST)) return marshal.dumps((self.id, stat))

Once you get this working, it is likely you will need to figure out creating a custom PUT()...

Good luck, Sean

Can anyone bring me up to speed on why my ZClasses cannot be manipulated via FTP/WebDAV, and what I need to do to make them so they can?

I was pleased to note that built in Zope objects perform admirably during FTP/WebDAV manipulation : I'd feared that changed files would revert to 'File' objects. (Irrational, I know). However, my lovely ZClass, that I've put so much time and energy into, does not work.

In FTP - I just get an error when I try to replace it. (Downloading is fine) In WebDAV - it sees my ZClass as a Folder. Downloads it as a Folder. Wierd.

I'll be happy as can be to get one of theses methods working. This is imperative as we use Dreamweaver as our site manager/editor.

Now, I've found this: http://www.zope.org/Members/akendall/zclassftp Seems relevant, but old as can be. I'm going to compare the files it alters with the ones that come with Zope 2.6, and hopefully I can distill some wisdom as to what needs changing. But if anyone can shed some light to help guide my way, I'd appreciate it.

Ed
