Question

I have the following table structure.
tb_posts has the field author_id which relates to tb_author.id
in YII i have the following in my posts activeRecord

public function relations()
{

    return array(
        'authorRelation' => array(self::BELONGS_TO, 'authorRecord', 'author')
    );
}

How i do a search of posts of an authors with name ‘foo’? I am trying the following with no success

$criteria=new CDbCriteria;
$criteria->with = array('authorRelation');
$criteria->together = true;
$criteria->compare( 'author.name', 'foo', true );
$posts=PostsRecord::model()->findAll($criteria);

Answer 1

Set table alias for your models at init.

class PostsRecord extends CActiveRecord
{
    // ...
    public function init() { $this->setTableAlias( 'postsrecord' ); }
    // ...
}

class AuthorRecord extends CActiveRecord
{
    // ...
    public function init() { $this->setTableAlias( 'authorrecord' ); }
    // ...
}

Finally:

$condition=new CDbCriteria;
$condition->with = array('authorRelation');
$condition->together = true;
$condition->condition = 'authorrecord.name=:authorname';
$condition->params = array( ':authorname' => 'foo' );
$posts=PostsRecord::model()->findAll($condition);
