我实施了类似于here显示的分页：
搜索\模型\ CourseTable
class CourseTable {
const RELEVANCE_TITLE = 5;
const RELEVANCE_DESCRIPTION = 2;
const RELEVANCE_MIN = 3;
protected $tableGateway;
public function __construct(TableGateway $tableGateway) {
$this->tableGateway = $tableGateway;
}
public function findAllByCriteria(CourseSearchInput $input) {
$concatDelimiter = self::CONCAT_DELIMITER;
$select = new Select();
$where = $this->buildWhereFromCriteria($input);
$having = new Having();
$select->columns(array(
...
));
$select->from($this->tableGateway->getTable());
$select
->join('...)) // and some more JOINs
;
$where
// condition
;
$having
->greaterThanOrEqualTo('relevance', self::RELEVANCE_MIN);
;
$select->where($where, Predicate::OP_AND);
$select->having($having);
$select->group(array('courses.id'));
$adapter = new \Zend\Paginator\Adapter\DbSelect($select, $this->tableGateway->getAdapter());
$paginator = new \Zend\Paginator\Paginator($adapter);
return $paginator;
// $resultSet = $this->tableGateway->selectWith($select);
// return $resultSet;
}
public function buildRelevanceExpressionFromCriteria(CourseSearchInput $input) {
$criteria = $input->getArrayCopy();
$relevanceTitle = self::RELEVANCE_TITLE;
$relevanceDescription = self::RELEVANCE_DESCRIPTION;
$expressionSQL = <<<SQL
MATCH (coursedata.title) AGAINST ('{$criteria['keyword']}') * $relevanceTitle +
MATCH (coursedata.description) AGAINST ('{$criteria['keyword']}') * $relevanceDescription
SQL;
return new Expression($expressionSQL);
}
function buildWhereFromCriteria(CourseSearchInput $input) {
...
}
}
搜索\控制器\ SearchController
class SearchController extends AbstractActionController {
protected $courseTable;
public function searchAction() {
return $this->redirect()->toRoute('search-courses');
}
public function searchCoursesAction() {
$form = $this->getServiceLocator()->get('Search\Form\CourseSearchForm');
$request = $this->getRequest();
if ($request->isPost()) {
$courseSearchInput = new CourseSearchInput();
$form->setInputFilter($courseSearchInput->getInputFilter());
$form->setData($request->getPost());
if ($form->isValid()) {
$courseSearchInput->exchangeArray($form->getData());
// $courses = $this->getCourseTable()->findAllByCriteria($courseSearchInput);
$courses = $this->getCourseTable()->findAllByCriteria($courseSearchInput);
$test = $courses->count();
} else {
$courses = null;
}
} else {
$courses = null;
}
return new ViewModel(array(
'form' => $form,
'courses' => $courses,
'cities' => $this->getServiceLocator()->get('Cache\Model\CityStorage')->getCities(),
));
}
function getCourseTable() {
...
}
}
现在抛出异常：

这是一个框架错误吗？
修改
我在$test = $select->getSqlString($this->tableGateway->getAdapter()->getPlatform());之前的行中使用$adapter = new \Zend\Paginator\Adapter\DbSelect($select, $this->tableGateway->getAdapter());生成的查询：
