To clarify: if you just want Owner roles, as opposed to Ownership[1][2][3],
you can do that with totally-non-ZODB objects.  I have a couple
different applications where totally SQL- or LDAP- are given local roles
(Owner and others) to implement security as you describe. 

The way we do it requires LoginManager to be in use, or to have patched
Zope with improvents to the local roles support (LM effectively hotfixes
these in for its own users). Then our DataSkins-based ZClasses also
mix in AppTabs[4], which has a get_local_roles_for_user() which tries
a LocalRolesForUser() method if it exists, otherwise falls back to older
means. Finally, you can define LocalRolesForUser to compute local roles
for the accessing user by whatever rules it wants.

[1] People may complain about ZPatterns terminology, but at least we
have the sense not to use the same word for two entirely different
concepts! :-)

[2] And I don't know why you'd care about Ownership for your objects in
this example...  it doesn't seem meaningful for these sorts of non-code
objects.

[3] Actually, maybe you could write SkinScript to provide the _owner
attribute. But see [2]...

[4] Unreleased product, still in some flux.  It mainly provides fancier,
more flexible version of Zope's management tabs, suitable for use in an
application (that is, suitable for exposing to users, not just
developers). It also has some local roles hooks as mentioned.

[Zope-dev] [ZPatterns] DataSkin object ownership

2000-12-12 Thread BS

Do DataSkins have ownership? I want to give multiple users the ability to
add objects to a rack and only allow the 'owner' to view/edit the object.
When a user adds a DataSkin to a rack does he get ownership of the object?
I can't seem to get the ownership information for these objects. Is there a
way to do this?

BTW - I'm talking about virtual object that totally live in MySQL.

Thanks,
-Ben

DataSkins stored in Racks do not participate in the Zope ownership
mechanism, nor the creation of the 'Owner' role.  This is because they are
not being stored via the normal ObjectManager protocols.  If you want this
behavior, you'll need to use Folders w/Customizer support, which let you
use most of DataSkins' dynamic features with "almost ordinary" Zope objects.

BTW - I'm talking about virtual object that totally live in MySQL.

Folders w/Customizer Support require the DataSkins' primary storage to be
in the ZODB.
