在蛋糕 2.1 中，我需要从包含的记录中求和一个字段。

目前我得到子表上所有记录的总和，但需要按我的主表（员工）的 id 分组。

参加属于员工

    $agents = $this->Employee->find('all', array(
        'fields' => array('Employee.FullNameNoId'),
        'conditions' => $conditions,
        'contain' => array(
            'Attend' => array(
                'conditions' => array(
                    'Attend.as_date BETWEEN ? AND ?' => array(
                        date('Y-m-d', strtotime($this->passedArgs['date1'])), 
                        date('Y-m-d', strtotime($this->passedArgs['date2']))
                    )
                ),
                'fields' => array('sum(Attend.as_labormin) AS total'),
                //'group' => array('Attend.employee_id') // This gets sql errors below
            )
        )
     ));

尝试了几种 SQL 错误的组合：

'group' => array('Attend.employee.id') // Model "Attend" is not associated with model "Attend" 
                                      //Column not found: 1054 Unknown column                     
'group' => array('employee_id')        // Model "Attend" is not associated with model "employee_id"
                                      // Column not found: 1054 Unknown column 'Attend.group' in 'field list'

'group' => array('Employee.id')           //Column not found: 1054 Unknown column Attend.group' in 'field list'

表之间的关系很好，我可以得到相关的记录，问题是通过员工ID得到一个总和。

检查了相关字段的 Cakephp SUM，但是使用 SELECT SUM 似乎很麻烦，并且他们遗漏了所需的分组。

你能帮我吗？

Try disabling 'autoFields'. It is known to cause SQL errors with aggregate functions and 'group by' statements. Find out more here
