我正在按照本教程进行自动完成，它工作正常，除了 MY_X 的自动完成不起作用。

如何在 MY_X 类中启用自动完成功能？
MY_model 的代码例如：
class MY_Model extends CI_Model {
public $auto_validate = TRUE; // use auto-validation before saving
public $return_method = 'auto'; // object, array, query, auto
public $auto_validate_fields = array(
'email|email_address' => 'valid_email',
'phone|phone_number' => 'valid_phone'
); // fields to auto validate
public $required = array(); // required fields
public $default_required_message;
//public $default_required_message = "Please fill out the required field '%1s'"; // the default required validator message
public $auto_date_add = array('date_added', 'entry_date'); // field names to automatically set the date when the value is NULL
public $auto_date_update = array('last_modified', 'last_updated'); // field names to automatically set the date on updates
public $date_use_gmt = FALSE; // datetime method
public $default_date = 0; // default date value that get's passed to the model on save. Using 0000-00-00 will not work if it is a required field since it is not seen as an empty value
public $auto_trim = TRUE; // will trim on clean
public $auto_encode_entities = TRUE; // automatically encode html entities
public $xss_clean = FALSE; // automatically run the xss_clean
public $readonly = FALSE; // sets the model to readonly mode where you can't save or delete data'
public $hidden_fields = array(); // fields to hide when creating a form
public $unique_fields = array(); // fields that are not IDs but are unique
public $linked_fields = array(); // fields that are are linked. Key is the field, value is a function name to transform it
public $foreign_keys = array(); // map foreign keys to table models
protected $db; // CI database object
protected $table_name; // the table name to associate the model with
protected $key_field = 'id'; // usually the tables primary key(s)... can be an array if compound key
protected $normalized_save_data = NULL; // the saved data before it is cleaned
protected $cleaned_data = NULL; // data after it is cleaned
protected $dsn = ''; // the DSN string to connect to the database... if blank it will pull in from database config file
protected $has_auto_increment = TRUE; // does the table have auto_increment?
protected $suffix = '_model'; // the suffix used for the data record class
protected $record_class = ''; // the name of the record class (if it can't be determined)
protected $rules = array(); // validation rules
protected $fields = array(); // fields in the table
protected $use_common_query = TRUE; // include the _common_query method for each query
protected $validator = NULL; // the validator object
