xo::db::CrFolder proc get_instance_from_db (public)

 xo::db::CrFolder get_instance_from_db [ -item_id item_id ] \
    [ -revision_id revision_id ] [ -initialize on|off ]

Defined in /var/www/openacs.org/packages/xotcl-core/tcl/cr-procs.tcl

The "standard" get_instance_from_db methods return objects following the naming convention "::<acs_object_id>", e.g. ::1234

Usually, the id of the item that is fetched from the database is used. However, XoWiki's "folder objects" (i.e. an ::xowiki::Object instance that can be used to configure the respective instance) are created using the acs_object_id of the root folder of the xowiki instance, which is actually the id of another acs_object.

Because of this, we cannot simply create the instances of CrFolder using the "standard naming convention". Instead we create them as ::cr_folder<acs_object_id>.

Switches:

-item_id (optional, defaults to "0")

-revision_id (optional, defaults to "0")

-initialize (optional, boolean, defaults to "true")
