If targetClass (opens new window) is set, this defines the model attributes that represent the record's primary key(s). Can be set to a string or array of strings of model attributes in the same respective order as the primary keys defined by the record's primaryKey() method, or can be set to an array of attribute/PK pairs, which explicitly maps model attributes to record primary keys. Defaults to whatever the record's primaryKey() method returns.
