Zend table row abstract model method thows Unrecognized method 'updateFromArray()'

I have very specific problem with my Zend Framework applic开发者_开发知识库ation. I use my own Model class called My_Model which is singleton and I use it for calling DB models. Every model extends My_Db_Table class and has a row class that extends My_Db_Table_Row. When I call the model it is OK but the model seems to ignore row class model. Could anybody advise me what am I doing wrong?

The custom class:

class My_Model {

protected static $_instance = null;

protected $_services = array();    

private function __construct() {        

}



/**

 * Service classed is called by it's name

 *

 * @param string $name

 * @return My_Db_Table

 */

public function getService($name) {

    if (!isset($this->_services[$name])) {

        $service = new $name();  

        if (!$service instanceof Zend_Db_Table_Abstract) {

            $type = gettype($service);

            if ($type == 'object') {

                $type = get_class($service);
            }

            throw new Zend_Db_Table_Row_Exception("Class must be a Zend_Db_Table_Abstract, but it is $type");

        }

        $this->_services[$name] = $service;

    }

    return $this->_services[$name];

}


}

The Zend_Db_Table classes are:

<?php

/**

 * This class represents a DB table

 *

 */

class My_Db_Table extends Zend_Db_Table_Abstract {



/**

 * Fetches the table row by primary key

 *

 * @param string $id

 * @return Product

 */

public function getById($id) {

    return $this->find($id)->current(); 

}

}

Row class:

<?php

/**

 * Row class

 *

 */

class My_Db_Table_Row extends Zend_Db_Table_Row_Abstract {

/**

 * Inflector to get the attribute name

 * camelCase -> under_score

 *

 * @param string $columnName

 * @return string

 */

protected function _transformColumn($columnName) {

    $inflector = new Zend_Filter_Inflector ( ":string" );

    $inflector->setRules ( array (

    ':string' => array ('Word_CamelCaseToUnderscore', 'StringToLower' ) ) )

    ;

    $columnName = $inflector->filter ( array ('string' => $columnName ) );

    return $columnName;

}

/**

 * Magic method hook to catch getters and setters

 *

 * @param string $method

 * @param array $args

 */

public function __call($method, array $args) {

    $matches = array ();

    if (preg_match ( '/^get(\w+?)$/', $method, $matches )) {

        $attribute = $matches [1];

        return $this->{$attribute};

    }

    if (preg_match ( '/^set(\w+?)$/', $method, $matches )) {

        $attribute = $matches [1];

        $this->{$attribute} = (count ( $args ) == 1) ? $args [0] : null;

        return;

    }

    return parent::__call ( $method, $args );

}

}

To use these classe I use following code:

$record = My_Model::getInstance ()->getService ( 'Users' )->getById ( 1 );
$record->updateFromArray(array('auth_token' => 'asfsgfgswg'));

And I get the following error message:

Message: Unrecognized method 'updateFromArray()'

The Users class:

 <?php

/**
 * User table model class
 *
 */
class Users extends My_Db_Table {

    /**
     * The DB table name
     *
     * @var string
     */
    protected $_name = 'user';

    /**
     * The row class name
     *
     * @var string
     */
    protected $_rowclass = 'User';

}

The User class that is not called with updateFromArray method:

<?php

/**
 * The user model class
 *
 */
class User extends My_Db_Table_Row {


    /**
     * Update values by array values
     *
     * @param array $values
     */
    public function updateFromArray(array $values) {
        $this->setFromArray($values);
        $this->save();
        return $this;
    }
}

I will provide any necessary info if needed. I am really stucked on this one for a few days now and nothing seems to help. The method updateFromArray is in the User class but the class is not loaded properly.

Thanks in advance for every help!

I think the problem may be that you are using $_rowclass and not $_rowClass (with an uppercase C).

If you put this line instead, it may work:

protected $_rowClass = 'User';

That's why in the stack trace you can see Zend_Db_Table being called, which is the default class for a a row that hasn't been set to use a custom class.
