Question

I need to find out how many times each value is duplicated. Here’s what I’ve got so far. I’d like to use it for counting votes in polls.

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

And it returns me which values are duplicated, like this:

1st answer
2nd answer
4th answer

But I still need the number, to show how many times it’s duplicated. Something like this.

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

EDIT:
Solution that worked for me

In controller:

$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'))));

In view:

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

Answer 1

This query will work.

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

CakePHP equivalent find condition:

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

You will find TotalVotes in a separate array at index [0]. To overcome this issue, just write the following code before your select query:

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