Body
I show you firsly my class : as you can see I repeated several times $versionId param because all the method needs it. I am asking myself if there is a way to factorize it so there is lesser repetition. <pre><code><?php class Admin_Model_Version { private $_db; private $_versionId; private $_path; public function __construct() { } /** * Récupère l'objet de la table version. * * @return Zend_Db_Table */ public function getDb() { if(!isset($this->_db)) { $this->_db = new Admin_Model_DbTable_Version(); } return $this->_db; } /** * Retourne toutes les versions d'un projet. * * @param integer $versionId */ public function getVersions($projectId) { $db = $this->getDb(); $select = $db->select(); return $select ->where("project_idproject = ?", $projectId) ->query()->fetchAll(); } public function getVersionPath($versionId) { $root = realpath(dirname($_SERVER['SCRIPT_FILENAME']) . "/../"); $patrimonyName = $this->getPatrimonyRecordByVersionId($versionId)->name_patrimony; $projectName = $this->getProjectRecordByVersionId($versionId)->name_project; $versionName = $this->getVersionRecordByVersionId($versionId)->lab_version; return $root . "/data/projects/" . $patrimonyName . "/" . $projectName . "/" . $versionName . "/"; } /** * Vérifie si la version possède un repertoire de travail. * * Tous les répertoires de travail sont dans le répertoire /data/projects/ */ public function hasVersionDirectory($versionId) { $versionPath = $this->getVersionPath($versionId); // Si le chemin n'existe pas retourner une exception. if(!realpath($versionPath)) { throw new Exception("Admin_Model_Version " . __LINE__ . " : Le répertoire n'existe pas!"); return false; } else { return true; } } public function getPatrimonyRecordByVersionId($versionId) { $db = $this->getDb(); // setIntegrityCheck(false) is required for join $row = $db->select()->setIntegrityCheck(false); return $row->from(array('ve' => 'version'), array()) ->join(array('pr' => 'project'), 've.project_idproject = pr.idproject', array()) ->join(array('pa' => 'patrimony'), 'pa.idpatrimony = pr.patrimony_idpatrimony') ->where('ve.idversion = ?', $versionId) ->query()->fetchObject(); } public function getProjectRecordByVersionId($versionId) { $db = $this->getDb(); // setIntegrityCheck(false) is required for join $row = $db->select()->setIntegrityCheck(false); return $row->from(array('ve' => 'version'), array()) ->join(array('pr' => 'project'), 've.project_idproject = pr.idproject') ->where('ve.idversion = ?', $versionId) ->query()->fetchObject(); } public function getVersionRecordByVersionId($versionId) { $db = $this->getDb(); // setIntegrityCheck(false) is required for join $row = $db->select(); $row->where('idversion = ?', $versionId); return $row->query()->fetchObject(); } /** * Crée le répertoire de travail avec comme chemin le nom du patrimoine * suivi du nom de projet et du nom de version. */ public function createHome($versionId) { $path = $this->getVersionPath($versionId); Zend_Registry::get('firephp')->info($path); if(!mkdir($path, 0755, true)) { throw new Exception(__METHOD__ . "can't create directory"); } } public function hasDirectorySRC($versionId) { $path = } public function hasDirectoryHTML($versionId) { } public function hasDirectoryXML($versionId) { } public function hasDirectorySVG($versionId) { } } </code></pre> Thx

1. COAs all your methods are marked as public, I assume they can be used with any versionId, which would mean it's ok this way.

Guidance

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.
