私はcakephpで新しく、cakephpでクエリを実装しようとしています。 私はこのクエリを持っていますCakephpの複数のテーブルからデータを取得する
SELECT * FROM question join question_topic on question.question_id=question_topic.question_id join topic on topic.topic_id=question_topic.topic_id join user_topic on user_topic.topic_id=topic.topic_id where user_topic .user_id=10
これはcakephpで必要です。私が試してみました何
この
$this->Behaviors->attach('Containable');
return $this->find('all', array(
'contain' => array(
'User',
'UserInfo.UserTopic'=>array(
'conditions'=>array('UserTopic.user_id'=>10)
),
'QuestionAndTopic.Topic','UpVoteQuestion','Answer','Answer.UserInfo'
),
'order' => 'rand()',
'recursive' => 0
));
である。しかし、クエリは私に右の結果を与えていません。見てみてください。
Question.php
class Question extends AppModel
{
public $useTable = 'question';
public $primaryKey = 'question_id';
public $belongsTo = array(
'User' => array(
'className' => 'User',
'foreignKey' => 'user_id',
'fields' => array('User.user_id','User.email','User.active')
),
'UserInfo' => array(
'className' => 'UserInfo',
'foreignKey' => 'user_id',
)
);
public $hasMany = array(
'Answer' => array(
'className' => 'Answer',
'foreignKey' => 'question_id',
),
'QuestionAndTopic' => array(
'className' => 'QuestionAndTopic',
'foreignKey' => 'question_id',
)
);
public function latestQuestions(){
$this->Behaviors->attach('Containable');
return $this->find('all', array(
'contain' => array(
'User',
'UserInfo.UserTopic'=>array(
'conditions'=>array('UserTopic.user_id'=>10)
),
'QuestionAndTopic.Topic','UpVoteQuestion','Answer','Answer.UserInfo'
),
'order' => 'rand()',
'recursive' => 0
));
}
}
