CakePHP分页计数不匹配查询？

Question

我有一个相当修改的分页查询使用了许多连接等 - 但由于某种原因,paginator-> counter()永远不会匹配计数查询的结果.

您可以在http://dev.qreer.com/上看到它的运行情况- 通过在LHS导航上选择各种选项,查询输出在下面,并且分页器计数看起来非常随机.

知道我可以开始调试这个吗？

在Jobs Controller中:

    $this->paginate = $this->Job->paginateParams($data);
    $jobs = $this->paginate('Job');
    $this->set(compact('jobs'));

在模型中:

function paginateParams($data = null){
        //lots of joins + conditions
        return array('contain' => $contain, 'recursive' => 0,'joins' => $joins, 'conditions' => $conditions, 'group' => 'Job.id', 'order' => $order);
    }

示例连接(所有连接表和数据表的内部连接):

        array(
            'table' => 'education_backgrounds',
            'alias' => 'EducationBackground',
            'type' => 'INNER',
            'conditions' => array('EducationBackgroundsJobs.education_background_id = EducationBackground.id'),
        ),

样品条件:

      'EducationBackground.name' => array('Aerospace Engineering');

这是因为group by我找到了一个解决方法.我想把链接但我已经丢失了,所以我会发布代码:

public function paginateCount($conditions = null, $recursive = 0, $extra = array()) {
    $parameters = compact('conditions', 'recursive');
    if (isset($extra['group'])) {
        $parameters['fields'] = $extra['group'];
        if (is_string($parameters['fields'])) {
            // pagination with single GROUP BY field
            if (substr($parameters['fields'], 0, 9) != 'DISTINCT ') {
                $parameters['fields'] = 'DISTINCT ' . $parameters['fields'];
            }
            unset($extra['group']);
            $count = $this->find('count', array_merge($parameters, $extra));
        } else {
            // resort to inefficient method for multiple GROUP BY fields
            $count = $this->find('count', array_merge($parameters, $extra));
            $count = $this->getAffectedRows();
        }
    } else {
        // regular pagination
        $count = $this->find('count', array_merge($parameters, $extra));
    }
    return $count;
}

我在app_model中添加了它,它对我来说很好:)

希望这可以帮助
