    <p>I am new to Zend and have been attempting to follow the <a href="http://framework.zend.com/manual/en/learning.quickstart.create-model.html" rel="nofollow">Zend Quick Start Guide's example</a> of using Data Mappers and extending Zend_Db_Table_Abstract. I think I've grasped the general concepts, but I am now wondering, how I would go about modifying the guide's example code to allow for multiple tables.</p> <p>Here is the part of the code I am currently interested in modifying:</p> <pre><code>protected $_dbTable; public function setDbTable($dbTable) { if (is_string($dbTable)) { $dbTable = new $dbTable(); } if (!$dbTable instanceof Zend_Db_Table_Abstract) { throw new Exception('Invalid table data gateway provided'); } $this-&gt;_dbTable = $dbTable; return $this; } public function getDbTable() { if (null === $this-&gt;_dbTable) { $this-&gt;setDbTable('Application_Model_DbTable_Guestbook'); } return $this-&gt;_dbTable; } </code></pre> <p>I have changed it to this:</p> <pre><code>protected $_dbTables; public function setDbTable($dbTable, $tableName) { if (is_string($dbTable)) { $dbTable = new $dbTable(); } if (!$dbTable instanceof Zend_Db_Table_Abstract) { throw new Exception('Invalid table data gateway provided'); } $this-&gt;_dbTables[$tableName] = $dbTable; return $this; } public function getDbTables() { if (null === $this-&gt;_dbTables) { $this-&gt;setDbTable('Application_Model_DbTable_Courses', 'courses'); $this-&gt;setDbTable('Application_Model_DbTable_CourseTimes', 'course_times'); } return $this-&gt;_dbTables; } </code></pre> <p>Is this a correct way to go about implementing multiple tables within the Data Mapper pattern or would you do it differently? Thanks for your help in advance!</p>

    1. COI now realise that my logic here was slightly faulty and caused by ignorance of the MVC pattern. My suggested solution in this question is not a good one, as there really should be only one table per mapper. If multiple simultaneous inserts are required they should either be invoked from the Controller or via another model.

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.
