you can also use the $fieldList parameter in the $modelName->save
http://api.cakephp.org/1.2/class_model.html#ebe42ae387be89985b5a35dd428f5c81
Model::save ( $ data = null,
$ validate = true,
$ fieldList = array()
)
Saves model data to the database. By default, validation occurs before save.
Parameters:
array $data Data to save.
boolean $validate If set, validation will be done before the save
array $fieldList List of fields to allow to be written
