<h2>How to use the database mapper with the paginator?</h2> I'm having a bit trouble understanding how I implement the DbSelect paginator using the code below (right now it's using the Iterator adapter which doesn't work for ResultSets). From what I can tell it's not as straight forward as I would have hoped. DbSelect is expecting a <code>Zend\Db\Sql\Select</code> and an adapter. The adapter is a non issue and can be retrieved with: <pre><code>$this->newsContents()->getAdapter() </code></pre> but I'm having trouble getting a <code>Select</code> object out from my TableGateway without duplicating my query code. Is there an easy way to solve this problem? NewsController.php <pre><code><?php namespace News\Controller; use Zend\Paginator\Paginator; class NewsController extends \Application\Controller\WebsiteController { protected $newsTable; protected $newsContents; protected function newsTable() { return $this->getServiceLocator()->get('News\Model\NewsTable'); } protected function newsContents() { return $this->getServiceLocator()->get('News\Model\NewsContentsTable'); } protected function articleId() { return (int) $this->params()->fromRoute('id'); } public function articleAction() { $article = $this->newsTable()->getArticle($this->articleId()); $pages = $this->newsContents()->getPages($this->articleId()); $paginator = new Paginator(new \Zend\Paginator\Adapter\Iterator($pages)); $paginator->setCurrentPageNumber($this->params()->fromRoute('page')); return array( 'css' => 'news.css', 'article' => $article, 'paginator' => $paginator, ); } } </code></pre> NewsContentsTable.php <pre><code><?php namespace News\Model; use Zend\Db\Adapter\Adapter; use Zend\Db\ResultSet\ResultSet; use Zend\Db\TableGateway\AbstractTableGateway; use Zend\Db\Sql\Select; class NewsContentsTable extends \Zend\Db\TableGateway\AbstractTableGateway { protected $table = 'news_contents'; public function __construct(Adapter $adapter) { $this->adapter = $adapter; $this->resultSetPrototype = new ResultSet; $this->resultSetPrototype->setArrayObjectPrototype(new NewsContents); $this->initialize(); } public function getPages($newsId) { $rowset = $this->select(function(Select $select) use ($newsId) { $select ->order('order ASC') ->where(array('news_id' => $newsId)); }); return $rowset; } } </code></pre>

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.
