Instance Method Details
#belongs_to(association_id, options = {}) ⇒ Object
belongs_to
This defines a method for an extension class map its DN key attribute value on to multiple items which reference it by |:foreign_key| in the other LDAP entry covered by class |:class_name|.
Example:
belongs_to :groups, :class_name => Group, :foreign_key => memberUid, :local_key => 'uid'

#has_many(association_id, options = {}) ⇒ Object
has_many
This defines a method for an extension class expand an existing multi-element attribute into ActiveLDAP objects. This discards any calls which result in entries that don’t exist in LDAP!
Example:
has_many :members, :class_name => User, :local_key => memberUid, :foreign_key => 'uid'
