php - 不能使用包含 cakephp 3

Question

我想从 quizdetails 表中选择问题数据。问题数据也将与答案表连接。所以我使用代码 php:

$questions = $this
    ->QuizDetails->find()
    ->contain([
        'Questions' => function($q) {
            return $q->contain(['Answers']);
        }
    ])
    ->where(['QuizDetails.quiz_id' => $id]);

文件答案表:

$this->table('answers');
$this->belongsTo('Questions', [
    'className' => 'Publishing.Questions',
    'foreignKey' => 'question_id',
]);

文件 QuizDetailsTable:

$this->table('quiz_details');
$this->belongsTo('Questions', [
    'className' => 'Publishing.Questions',
    'foreignKey' => 'question_id',
]);

所以，当我运行它时，通过一个错误 问题与答案无关

如果我使用:

$question = $this->Questions->find()->contain(['Answers'])

没关系。 请帮助我修复它。

Answer 1

如果我没记错的话，您只需要在 QuizDetails 中包含问题和答案，如果是这样，只需尝试:

$questions = $this->QuizDetails->find()->contain(['Questions.Answers'])
             ->where(['QuizDetails.quiz_id' => $id]);
