Cakephp和Group by

这就是我灌输的:

 $options = array(
                    'conditions' => $conditions,
                    'fields'=>array('Category.*','COUNT(`Entity`.`id`) as `entity_count`'),
                    'joins' => array('LEFT JOIN `entities` AS Entity ON `Entity`.`category_id` = `Category`.`id`'),
                    'group' => '`Category`.`id`',
                    'contain' => array('Domain' => array('fields' => array('title')))
                );

                return $this->find('all', $options);

Model->find() 有一个 group 帕拉姆

默认情况下可能的键,所有这些键都是可选的:

$params = 
        array(
        'conditions' => array('Model.field' => $thisValue), //array of conditions
        'recursive' => 1, //int
        //array of field names
        'fields' => array('Model.field1', 'DISTINCT Model.field2'),
        //string or array defining order
        'order' => array('Model.created', 'Model.field3 DESC'),
        'group' => array('Model.field'), //fields to GROUP BY
        'joins' => array('Join relations here'), // for ex: LEFT JOIN `entities` AS Entity ON `Entity`.`category_id` = `Category`.`id`
        'limit' => n, //int
        'page' => n, //int
        'offset' => n, //int
        'callbacks' => true //other possible values are false, 'before', 'after'
    );

查询:

$resp = find('all', $params);

debug($resp);
