Zend-Framework 2 pagination join tables - zend-framework2

Question

I need to add a pagination in this code:
$select = new \Zend\Db\Sql\Select ;
$select->from('school');
$select->join('school_parent','school.school_parent_id = school_parent.school_parent_id');
$resultSet = $this->tableGateway->selectWith($select);
return $resultSet;
I tried this example, but I can't do it with the join table.
Anyone can help me?

Answer 1

public function fetchAll($paginated=false)
{
if($paginated) {
// create a new Select object for the table album
$select = $this->getallAlbum();
// create a new result set based on the Album entity
$resultSetPrototype = new ResultSet();
$resultSetPrototype->setArrayObjectPrototype(new Album());
// create a new pagination adapter object
$paginatorAdapter = new DbSelect(
// our configured select object
$select,
// the adapter to run it against
$this->tableGateway->getAdapter(),
// the result set to hydrate
$resultSetPrototype
);
$paginator = new Paginator($paginatorAdapter);
return $paginator;
}
$resultSet = $this->tableGateway->select();
return $resultSet;
}
function getallAlbum(){
$sql = new Select();
$sql->from('album')->columns(array('id', 'artist', 'title'))->join('albumcategory', 'album.catId = albumcategory.catId', array('catName' => 'catName'), Select::JOIN_LEFT);
return $sql;
}

Answer 2

Pagination should work fine with joins. This is what I have, similar to an example you provided:
$select = new \Zend\Db\Sql\Select ;
$select->from('school');
$select->join('school_parent','school.school_parent_id = school_parent.school_parent_id');
return new \Zend\Paginator\Paginator(
new \Zend\Paginator\Adapter\DbSelect(
$select,
$this->tableGateway->getAdapter()
)
);
Please post an exact error that you are getting if the above doesn't work.

Answer 3

Thank you for the answer, but i tried your code, but i had this PDOException message:
SQLSTATE[42S21]: Column already exists: 1060 Duplicate column name 'school_parent_id'
I also tried, to adapat my "join tables" with the example of Rob Allen:
public function fetchAll($paginated=false)
{
if($paginated) {
// create a new Select object for the table album
$select = new \Zend\Db\Sql\Select ;
$select->from('school');
$select->join('school_parent','school.school_parent_id = school_parent.school_parent_id');
// create a new result set based on the Album entity
$resultSetPrototype = new ResultSet();
$resultSetPrototype->setArrayObjectPrototype(new School());
// create a new pagination adapter object
$paginatorAdapter = new DbSelect(
// our configured select object
$select,
// the adapter to run it against
$this->tableGateway->getAdapter(),
// the result set to hydrate
$resultSetPrototype
);
$paginator = new Paginator($paginatorAdapter);
return $paginator;
}
$resultSet = $this->tableGateway->select();
return $resultSet;
}
But the result is the same.

Answer 4

// create a new Select object for the table album
$select = new \Zend\Db\Sql\Select ;
$select->from('school');
$select->join('school_parent','school.school_parent_id = school_parent.school_parent_id');
//change this like the following
// create a new Select object for the table album
$select = $this->yourFunction();
//and define yourFunction like
function youFunction(){
$sql = new Select();
$sql->from('school')->columns(array('schoolid', 'schoolname', 'anotherfield'))->join('school_parent', 'school.school_parent_id= school_parent.school_parent_id', array('schoolName' => 'schoolName'), Select::JOIN_LEFT);
return $sql;
}

Answer 5

Please try the join syntax
$select->from('table1')->join('table2', 'table1 = table2', array('table2.colum_to_return1', 'table2.colum_to_return2'));

Example pagination and sort Url

Answer 7

Try with another example pagination and sorting
### module_config.php ###
'router' => array(
'routes' => array(
'album' => array(
'type' => 'segment',
'options' => array(
'route' => '/album[/:action][/:id][/page/:page][/order_by/:order_by][/:order]',
'constraints' => array(
'action' => '(?!\bpage\b)(?!\border_by\b)[a-zA-Z][a-zA-Z0-9_-]*',
'id' => '[0-9]+',
'page' => '[0-9]+',
'order_by' => '[a-zA-Z][a-zA-Z0-9_-]*',
'order' => 'ASC|DESC',
),
'defaults' => array(
'controller' => 'Album\Controller\Album',
'action' => 'index',
),
),
),
),
),
###### AlbumController ###
namespace Album\Controller;
use Zend\Mvc\Controller\AbstractActionController;
use Zend\View\Model\ViewModel;
use Album\Model\Album;
use Album\Form\AlbumForm;
use Zend\Db\Sql\Select;
use Zend\Paginator\Paginator;
use Zend\Paginator\Adapter\Iterator as paginatorIterator;
class AlbumController extends AbstractActionController {
protected $albumTable;
public function indexAction() {
$select = new Select();
$order_by = $this->params()->fromRoute('order_by') ?
$this->params()->fromRoute('order_by') : 'id';
$order = $this->params()->fromRoute('order') ?
$this->params()->fromRoute('order') : Select::ORDER_ASCENDING;
$page = $this->params()->fromRoute('page') ? (int) $this->params()->fromRoute('page') : 1;
$albums = $this->getAlbumTable()->fetchAll($select->order($order_by . ' ' . $order));
$itemsPerPage = 10;
$albums->current();
$paginator = new Paginator(new paginatorIterator($albums));
$paginator->setCurrentPageNumber($page)
->setItemCountPerPage($itemsPerPage)
->setPageRange(7);
return new ViewModel(array(
'order_by' => $order_by,
'order' => $order,
'page' => $page,
'paginator' => $paginator,
));
}
}

Answer 8

Add this line to your code:
$select->columns(array(new Expression('DISTINCT school.school_parent_id')));
OR something like this:
$select->join('school_parent','school.school_parent_id = school_parent.school_parent_id', array('sp_id' => 'school_parent_id'));
