这个问题似乎弹出了很多,但是没有一个答案能帮助我解决我的问题。
概括
- 我正在使用 Yii 创建一个应用程序;
- 我有三个表,我正在尝试对其中两个进行联接和过滤;
- 我正在尝试使用 CDbCriteria 和 CActiveDataProvider 进行连接和过滤;
- 我有所有表的模型,但是当我尝试加入它们时,我得到一个 SQL 错误。
表
我为要加入和过滤的表创建了一个模型。
记录
class Record extends CActiveRecord {
public $owner;
...
public function rules() {
return array(
array('given_name, family_name, dob, gender', 'required'),
array('qr_id, site_id', 'numerical', 'integerOnly' => true),
array('given_name, family_name, madin_name', 'length', 'max' => 100),
array('country_of_birth, country_of_death, title', 'length', 'max' => 45),
array('gender', 'length', 'max' => 5),
array('dod, profile, epitaph', 'safe'),
array('id, qr_id, given_name, family_name, madin_name, dob, dod, country_of_birth, country_of_death, gender, owner', 'safe', 'on' => 'search'),
);
}
...
public function relations() {
return array(
'families_left' => array(self::HAS_MANY, 'Family', 'record_left_id'),
'families_right' => array(self::HAS_MANY, 'Family', 'record_right_id'),
'headstones' => array(self::HAS_MANY, 'Headstone', 'record_id'),
'other_names' => array(self::HAS_MANY, 'OtherName', 'record_id'),
'users' => array(self::MANY_MANY, 'Users', 'record_owner(record_id, user_id)'),
'record_owner' => array(self::HAS_MANY, 'RecordOwner', 'record_id'),
);
}
...
}
记录所有者
class RecordOwner extends CActiveRecord {
...
public function relations() {
// NOTE: you may need to adjust the relation name and the related
// class name for the relations automatically generated below.
return array();
}
...
}
问题
我更新了搜索,在 CDbCriteria 中添加了关于 record_owner 的条件,我在 record_owner.user_id 上添加了比较,但现在出现 SQL 错误。
搜索()
public function search() {
// Warning: Please modify the following code to remove attributes that
// should not be searched.
$criteria = new CDbCriteria;
$criteria->compare('id', $this->id);
$criteria->compare('qr_id', $this->qr_id);
$criteria->compare('given_name', $this->given_name, true);
$criteria->compare('family_name', $this->family_name, true);
$criteria->compare('madin_name', $this->madin_name, true);
$criteria->compare('dob', $this->dob, true);
$criteria->compare('dod', $this->dod, true);
$criteria->compare('country_of_birth', $this->country_of_birth, true);
$criteria->compare('country_of_death', $this->country_of_death, true);
$criteria->compare('gender', $this->gender, true);
$criteria->compare('title', $this->title, true);
$criteria->with = array('record_owner');
$criteria->compare( 'record_owner.user_id', $this->owner, true );
return new CActiveDataProvider(
$this,
array(
'criteria' => $criteria,
'pagination' => array(
'pageSize' => Yii::app()->params['pageSize'],
)
)
);
}
SQL 错误
CDbCommand failed to execute the SQL statement: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'record_owner.user_id' in 'where clause'. The SQL statement executed was: SELECT `t`.`id` AS `t0_c0`, `t`.`qr_id` AS `t0_c1`, `t`.`given_name` AS `t0_c2`, `t`.`family_name` AS `t0_c3`, `t`.`madin_name` AS `t0_c4`, `t`.`dob` AS `t0_c5`, `t`.`dod` AS `t0_c6`, `t`.`country_of_birth` AS `t0_c7`, `t`.`country_of_death` AS `t0_c8`, `t`.`gender` AS `t0_c9`, `t`.`profile` AS `t0_c10`, `t`.`epitaph` AS `t0_c11`, `t`.`site_id` AS `t0_c12`, `t`.`title` AS `t0_c13` FROM `record` `t` WHERE (record_owner.user_id LIKE :ycp0) ORDER BY `t`.`given_name` LIMIT 25
问题
我应该如何做这个加入和过滤?
