Question

我有以下表格：

患者

id
first_name
姓氏

事件

ID
patient_id
EVENT_DESCRIPTION

通知

ID
event_id的
notification_description

我的模型中定义了以下关系：

Notification.php

public function relations()
{
    return array(
                'event' => array(self::BELONGS_TO, 'Event', 'event_id'),
            );
}

Event.php

public function relations()
{
    return array(
                'patient' => array(self::BELONGS_TO, 'Patient', 'patient_id'),
    );
}

我希望获得姓名为“Joe”且姓氏为“Smith”的患者的所有通知。有没有办法在不写出SQL语句的情况下做到这一点？

您需要自定义搜索功能，例如：

    public function searchCandidates() {
// Warning: Please modify the following code to remove attributes that
// should not be searched.

        $criteria = new CDbCriteria;

        $criteria->with = array('candidate_relation');//this is a relation; you can pute here, relation_a.relation_b.relation_c
        $criteria->compare('id', $this->id);
        $criteria->compare('email', $this->email, true);
        $criteria->compare('password', $this->password);
        $criteria->compare('created', $this->created);
        $criteria->compare('lastmodified', $this->lastmodified);
        $criteria->compare('confirmed', $this->confirmed);
        $criteria->compare('is_candidate', 1);
        $criteria->compare('username', $this->username, true);
        $criteria->compare('candidate_relation.first_name', $this->full_name, true);//and another relation here ...
        $criteria->compare('candidate_relation.last_name', $this->full_name, true, 'OR');

        return new CActiveDataProvider($this, array(
            'criteria' => $criteria,
        ));
    }

其中full_name是模型的自定义属性：public $full_name;

Yii查询通过多个属于关系
