Method Details

get(self, obj, cls)

Descriptor interface method to retrieve reference of referenced object for application object.

Parameters:: obj - Application object.; cls - Application class.

Returns:: Referenced object when obj is not null, otherwise descriptor object.

set(self, obj, value)

Descriptor interface method to set application object's attribute and foreign key values.

This method is optimized for uni-directional one-to-one association.

Parameters:: obj - Application object.; value - Referenced object.

saveForeignKey(self, obj, vkey)

Save referenced object's primary key value.

Application object's foreign key value is set to referenced object's primary key value.

Parameters:: obj - Application object.; vkey - Referenced object primary key value.

Overrides:: bazaar.assoc.AssociationReferenceProxy.saveForeignKey
