[ZF] Best practice extending Zend_Db_Table_Abstract?

[oxodesign]

Hi,

I have used Zend Framework for some small projects and plan to use it for a larger one. But what I wonder is what kind of methods you use for Zend_Db, what kind of pattern? Etc..

I have used a mapper and extended Zend_Db_Table_Abstract for each table, example:

<?php
class user {
    public $id;
    public $name;
    protected $_mapper = null;
    private function setMapper() {
        $this->_mapper = new userMapper();
    }
    private function getMapper() {
        if ($this->_mapper === null) {
            $this->setMapper ();
        }
        return $this->_mapper;
    }
    public function insert() {
        return $this->_mapper->insert($this);
    }
    public function update(){
        return $this->_mapper->update($this);
    }
}
?>

<?php
class userMapper {
    protected $_table = null;
    private function setTable() {
        $this->_table = new UserDbTable();
    }
    private function getTable() {
        if($this->_table === null) {
            $this->setTable();
        }
        return $this->_table;
    }
    public function insert(user $user) {
        return $this->getTable()->insert( array(data ) );
    }
    Public function update(user $user) {
        return $this->getTable()->update(array("data"), 'id=' . $user->id);
    }
}
?>

<?php
class userDbTable extends Zend_Db_Table_Abstract {
    protected $_name = 'users';
}
?>

Is it the right way, or can it be done otherwise?

Thanks
