如何统计cakephp中的重复值？

我需要找出每个值的重复次数。这是迄今为止我所拥有的。我想用它来进行民意测验中的投票。如何统计cakephp中的重复值？

$this->set('votes', $this->Answer->Vote->find('all', array(
        'fields' => array('Vote.answer_id'), 
        'group' => array('Vote.answer_id HAVING COUNT(*) > 1'))));

，并返回我该值是重复的，就像这样：

1st answer 
2nd answer 
4th answer

但我仍然需要的数量，以显示它是多少次重复。像这样的东西。

1st answer (5) 
2nd answer (3) 
3rd answer (1) // not duplicated 
4th answer (8)

编辑：解决方案，能为我工作

在控制器：

$this->set('votes', $this->Answer->Vote->find('all', array(
     'fields' => array('Vote.answer_id', 'count(*) as TotalVotes'), 
     'group' => array('Vote.answer_id HAVING COUNT(*) >= 1'))));

鉴于：

foreach ($votes as $vote): 
echo $vote[0]['TotalVotes']; 
endforeach;

您在select查询中只指定了一个字段，创建一个虚拟列tha t会计算答案。很容易你可以数它们。 –

这个查询工作。

SELECT answer_id, COUNT(*) AS TotalVotes FROM votes GROUP BY answer_id HAVING COUNT(*) > 1

CakePHP的等效查找条件：

$result = $this->Answer->Vote->find('all', array(
       'fields' => array('Vote.answer_id', 'count(*) as TotalVotes'), 
       'group' => array('Vote.answer_id HAVING COUNT(*) > 1')));

您将在index [0]找到TotalVotes在一个单独的阵列。为了解决这个问题，只是你的选择查询之前写上如下代码：

$this->Answer->Vote->virtualFields['TotalVotes'] = 0;

请问如果它不适合你。 –

它适用于我一个小小的变化。谢谢！我稍后会发布解决方案，因为'声誉低于10的用户在询问'政策后8小时内无法回答自己的问题:) – danny3b

这也适用于：

$this->set('votes', $this->Answer->Vote->find('all', array(
     'fields' => array(
      '*', 
      '(SELECT COUNT(*) FROM votes WHERE answer_id = Vote.answer_id) AS `count`'), 
     'group' => array('Vote.answer_id HAVING COUNT(*) >= 1') 
           )));

在这里，您可以从多个重复的记录

搜索记录组
