hi ZPattern-Freaks out there,
i want to write an ImapClient for CyrusImap as Zope-Product.
- Handle several Mailboxes
- Use Zope-Management for IMAP-Folder-Management and ACL/Security
- Use Custom-Interface as Mailclient
The Final Structue I want to have. It should act like a standart Zope
Folder-Tree:
- ImapClient ( holds Connection-Objects toIMAP-Mailboxes, Storage=ZODB)
|- ImapRootFolder ( Connection-Object and Root-Folder , Storage=ZODB)
| |-ImapFolder (a folder on the imapserver, not persitantly stored)
| | |-ImapFolder (..)
| | | | ...
| | |-ImapMessage (a message on the imapserver, not persitantly stored)
| |-ImapMessage (..)
|- ImapRootFolder (..)
| |-ImapFolder (..)
| | |-ImapFolder (..)
| | | | ...
| | |-ImapMessage (..)
| |-ImapMessage (..)
after big thougths about whether to use an Implementation like
- ZLDAPConnection
* A Root Connection Object
class ZLDAPConnection (Acquisition.Implicit,Persistent,
OFS.SimpleItem.Item,...)
* the nodes ar stored in a Tree of Entries
class Entry(Acquisition.Implicit,OFS.SimpleItem.Item)
or LocalFS does quite the same ...
BUT:
I want to be able to "skin" every meta_type separately, but I cannot just
use Acquisition because
of duplicates like "index_html"
-------------------
- Use a Specialist
AFAIK a Rack can only serve one meta-type
It's hard to implement the Folder Structure in racks
-------------------
- Use a Folder w/Customizer
this pretty looks like the one to use ...
but phillip told me some time ago,that
I can use it only with persistant ZODB-Storage like other zope-objects -
just use Dataskins with factory.
So I decided to give it a try.
I now have an ImapClient (CustomizerFolder)
which stores ImapRootFolder(Dataskin,Acquisition.Implicit,Folder)
the RootFolder emulates an ObjectManager to serve the Folders
retrieved from the IMAP-Server.
The ImapFolder-Objects are stored in an Attribute Children which is a List.
and are created like this:
def IMAPFolderFactory(client,Name,FullName="", PaddedName=""):
handle = ImapDataSkins.ImapFolder(Name)
handle._setRack(client.aq_inner.aq_parent._getDataManagerFor(handle))
handle.__dict__['_rackMounted'] = 0
handle = handle.__of__(client)
handle.setup(Name,FullName,PaddedName)
return handle
Now I have an Tree I can browse in the ZMI ... BUT ...
"I lose contact to Zope" when i browse down into the
first object wich is not persistantly stored.
I allthough don't get the "mapped Attributes/Methods" from the Customizer.
Is there a possiblity to use the CustomizerFolder with not ZODB-Objects
- What Methods need to be implemented that this could work
any help appreciated .. don't want to stop halfway ;-) ..
thanks Ulrich Eck
