我有三张桌子:
以及其中两个与MANY到MANY关系的模型
tbl_social_messages_list:
return array(
'service' => array(self::BELONGS_TO, 'SocialServices', 'service_id'),
'mtypes' => array(self::MANY_MANY, 'SocialMessageTypes', 'tbl_social_messages_mtypes_relation(m_id, t_id)' ),
);
tbl_social_message_types
return array(
'messages' => array(self::MANY_MANY, 'SocialMessages', 'tbl_social_messages_mtypes_relation(t_id, m_id)' ),
);
我正在尝试使用下拉列表和tbl_social_message_types.id进行网格过滤以进行比较。
我的搜索:
$criteria=new CDbCriteria;
$criteria->compare('mtypes.id', $this->mType);
$criteria->compare('t.id',$this->id);
$criteria->compare('t.service_id',$this->service_id);
$criteria->compare('t.title',$this->title,true);
$criteria->compare('t.comment',$this->comment,true);
$criteria->compare('t.category_id',$this->category_id,true);
$criteria->with = array('service', 'mtypes');
$criteria->order = 't.id DESC';
return new CActiveDataProvider($this, array(
'criteria'=>$criteria,
'pagination'=>array(
'pageSize'=>50,
),
));
但是当我发出请求(更改过滤器字段)时,Yii返回DB错误:
CDbCommand无法执行SQL语句:SQLSTATE [42S22]:找不到列:1054未知列&m; 39&mtypes.id'在' where子句'。执行的SQL语句是:
SELECT `t`.`id` AS `t0_c0`, `t`.`service_id` AS `t0_c1`, `t`.`category_id` AS `t0_c2`, `t`.`title` AS `t0_c3`, `t`.`comment` AS `t0_c4` FROM `tbl_social_messages_list` `t` WHERE (mtypes.id=:ycp0) ORDER BY t.id DESC LIMIT 50
据我所知,表 mtypes 不存在,但我无法理解 - 为什么会发生这种情况。
答案 0 :(得分:2)
首先尝试放置with
条件:
$criteria = new CDbCriteria;
$criteria->with = array('service', 'mtypes');
$criteria->compare('mtypes.id', $this->mType);
$criteria->compare('t.id', $this->id);
$criteria->compare('t.service_id', $this->service_id);
$criteria->compare('t.title', $this->title, true);
$criteria->compare('t.comment', $this->comment, true);
$criteria->compare('t.category_id', $this->category_id, true);
$criteria->order = 't.id DESC';
return new CActiveDataProvider($this, array(
'criteria'=>$criteria,
'pagination'=>array(
'pageSize'=>50,
),
));
如果它不起作用,有时候Yii需要一起“#”; =>真参数。
$criteria = new CDbCriteria;
$criteria->with = array('service' => array('together' => true),
'mtypes' => array('together' => true));
$criteria->compare('mtypes.id', $this->mType);
$criteria->compare('t.id', $this->id);
$criteria->compare('t.service_id', $this->service_id);
$criteria->compare('t.title', $this->title, true);
$criteria->compare('t.comment', $this->comment, true);
$criteria->compare('t.category_id', $this->category_id, true);
$criteria->order = 't.id DESC';
return new CActiveDataProvider($this, array(
'criteria'=>$criteria,
'pagination'=>array(
'pageSize'=>50,
),
));
