我有表:driver,driver_negotiation,base_negotiation和team
在DriverController模型中,我想获得驱动程序正在协商的team_id(位于base_negotiation中)。
在Driver模型中我有:
'driverNegotiation' => array(self::HAS_ONE, 'DriverNegotiation', 'driver_id')
在DriverNegotiation中:
'baseNegotiation' => array(self::BELONGS_TO, 'BaseNegotiation', 'base_negotiation_id')
在DriverController中我正在构建类似的东西:
$criteria=new CDbCriteria(array(
'condition' => 'baseNegotiation.team_id=13',
'with' => 'driverNegotiation',
'together' => true,
));
但我明白了:
Column not found: 1054 Unknown column 'baseNegotiation.team_id' in 'where clause'.
The SQL statement executed was: SELECT COUNT(DISTINCT `t`.`id`) FROM `driver` `t`
LEFT OUTER JOIN `driver_negotiation` `driverNegotiation` ON
(`driverNegotiation`.`driver_id`=`t`.`id`) WHERE (baseNegotiation.team_id=13)
所以我可以从driver_nagotiation表中获取所有内容,但不能从一个表中获取任何内容。
我是否需要使用联接来获取正确的内容,还是有更好的方法?
答案 0 :(得分:2)
'with' => 'driverNegotiation.baseNegotiation'
这就是诀窍。
