I have also been working on Object Ownership and the
userfolder app. In the userfolder app there is an added
method named 'store'. This method allows you to identify a
unique or shared table that is different that the default
used for that specific object instance.
In the user table there are two indices one called PID
(parent identifier) the other OID (object identifier). PID
signifies parent id. One user may be a child of another
user made so by the relational pid. The OID signifies the
userfolder Object instance that the user belongs inside.
The oid is a relational key from the main objects table id
integer of that specific userfolder object instance.
In regards to object ownership there can only be one
owner
per object which is based on the user who edited or created
said Object. a Objects capabilites are limited to the users
access permissions. Therefore, if a user cannot addFiles to
a folder object he created but then another user who does
have those writes edits his folder or takes ownership of
the folder then that user would be able to then addFiles to
that folder object.
The control panels access can never be overwritten. The
master of a PHPortal instance is the user id =1 which also
cannot be deleted. The control panel methods cannot change
ownership either.
The 'take ownership' (of objects) method is only
available
to those users who acquire that permission based on the
master's settings for his local user roles.
