我得到了一个带有2个模型PosTable / TopTable的ZF2项目,它扩展了AbstractTableGateway。
我想从这些表中分析结果,所以我在这两个表中都有分页功能。
这就是PosTable模型的样子:
...
class PosTable extends AbstractTableGateway {
public function __construct($adapter) {
$this->table = 'pos';
$this->adapter = $adapter;
}
...
public function getPosPaginator($tid) {
$sql = $this->getSql();
$select = $sql->select();
$select->where('tid = '.$tid)->where('deleted = 0')->order('crdate ASC');
$adapter = new \Zend\Paginator\Adapter\DbSelect($select, $sql);
$paginator = new \Zend\Paginator\Paginator($adapter);
return $paginator;
}
...
完美无缺。 但在我的TopTable中看起来像这样:
...
class TopTable extends AbstractTableGateway {
public function __construct($adapter) {
$this->table = 'top';
$this->adapter = $adapter;
}
public function getTopPaginator($fid) {
$sql = $this->getSql();
$select = $sql->select();
$select->where('fid = '.$fid)->where('deleted = 0');
$adapter = new \Zend\Paginator\Adapter\DbSelect($select, $sql);
$paginator = new \Zend\Paginator\Paginator($adapter);
return $paginator;
}
...
我的控制器对于PosTable来说是这样的:
...
public function posAction(){
...
$pos = $this->getPosTable()->getPosPaginator($tid);
$pos->setCurrentPageNumber($pageid)->setItemCountPerPage(19);
... return $pos etc...
相同的控制器topAction:
...
public function topAction(){
...
$top = $this->getTopTable()->getTopPaginator($fid);
$top->setCurrentPageNumber($pageid)->setItemCountPerPage(20);
...return $top etc..
在那个控制器里我也得到了这些功能:
public function getTopTable(){
return $this->getServiceLocator()->get('Application\Model\TopTable');
}
public function getPosTable(){
return $this->getServiceLocator()->get('Application\Model\PosTable');
}
PosTable Pagination完美无缺,但TopTable分页无效。 我收到这个错误:
Fatal error: Call to a member function select() on a non-object in ....
好像是
$sql = $this->getSql();
不返回该对象。 我怎么解决这个问题? 一个人工作一个没有明显的原因。
我的module.php看起来像这样:
namespace Application;
class Module
{
public function getAutoloaderConfig()
{
return array('Zend\Loader\StandardAutoloader' =>
array('namespaces' =>
array(__NAMESPACE__ => __DIR__ . '/src/' . __NAMESPACE__,),
),
);
}
public function getConfig()
{
return include __DIR__ . '/config/module.config.php';
}
public function getServiceConfig()
{
return array(
'factories' => array(
'Application\Model\TopTable' => function($sm) {
$dbAdapter = $sm->get('Zend\Db\Adapter\Adapter');
$table = new \Application\Model\TopTable($dbAdapter);
return $table;
},
'Application\Model\ForTable' => function($sm) {
$dbAdapter = $sm->get('Zend\Db\Adapter\Adapter');
$table = new \Application\Model\ForTable($dbAdapter);
return $table;
},
'Application\Model\PosTable' => function($sm) {
$dbAdapter = $sm->get('Zend\Db\Adapter\Adapter');
$table = new \Application\Model\PosTable($dbAdapter);
return $table;
},
),
);
}
}
答案 0 :(得分:1)
好的,经过TableGateway Code和你的扩展类后,我发现你的实现没有调用initialize,sql对象尝试调用父表网关,下面是你的PosTable和TopTable的修改构造函数
/* for PosTable */
class PosTable extends TableGateway {
public function __construct($adapter) {
parent::__construct('pos', $adapter);
}
...
/* for TopTable */
class TopTable extends TableGateway {
public function __construct($adapter) {
parent::__construct('top', $adapter);
}
...
