I'm not sure if it's the best practice, but, this is my abstract mapper: <pre><code><?php abstract class Zf_Model_DbTable_Mapper { protected $_db; protected $_dbTable = null; protected $_systemLogger = null; protected $_userLogger = null; public function __construct() { $this->_systemLogger = Zend_Registry::get('systemLogger'); $this->_userLogger = Zend_Registry::get('userLogger'); // Set the adapter if(null !== $this->_dbTable) { $tableName = $this->_dbTable; $this->_db = $this->$tableName->getAdapter(); } } public function __get($value) { if(isset($this->$value)) { return $this->$value; } $dbTable = 'Model_DbTable_' . $value; $mapper = 'Model_' . $value; if(class_exists($dbTable)) { return new $dbTable; } elseif(class_exists($mapper)) { return new $mapper; } else { throw new Exception("The property, DbTable or Mapper \"$value\" doesn't exists"); } } public function __set($key,$value) { $this->$key = $value; } public function getById($id) { $resource = $this->getDefaultResource(); $id = (int)$id; $row = $resource->fetchRow('id =' . $id); if (!$row) { throw new Exception("Count not find row $id"); } return $row; } public function getAll() { $resource = $this->getDefaultResource(); return $resource->fetchAll()->toArray(); } public function save(Zf_Model $Model) { $dbTable = $this->getDefaultResource(); $data = $Model->toArray(); if(false === $data) return false; if(false === $Model->isNew()) { if(1 == $dbTable->update($data, 'id =' .

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
