如何使用查找與'或'條件爲belongsToMany，belongsTo表

Question

我不知道如何獲得一個'或'conditon數據在一個belongsstomany表。我有一張課桌，導師桌和一張學生桌。我爲firstname傳遞一個變量。例如，如果我通過'fred'這個名字，那麼我想讓所有的學生和導師的名字都是'fred'。 我嘗試了一個匹配子句，但是減少了來自主模型的數據，因此無法正確。我使用的地方，但沒有工作，因爲我相信我不能用於這種屬於自己的關係。如何做到這一點請

查詢得到了這列未找到：1054未知列「Students.first_name」在「where子句」

Answer 1

我通過除去學生belongstomany關係找到了答案，把它改成了哈曼。這是一個相當大的變化，但這種歸屬感的關係有時會讓人頭疼。

$query3 = $this->find() 
       ->contain(['Tutors','Subjects', 'TutoringTypes','Terms','Students']) 
       ->select(['Lessons.id','Lessons.lesson_date','Tutors.id','Tutors.first_name','Tutors.last_name', 
        'Students.id','Students.first_name','Students.last_name', 
        'Subjects.name','TutoringTypes.value'])  
       ->where(['Lessons.lesson_date >' => $a3 , 
        'OR' => [[ 'Tutors.first_name like' => '%'.$firstname.'%', 'Tutors.last_name like' => '%'.$lastname.'%'], 
          ['Students.first_name like' => '%'.$firstname.'%', 'Students.last_name like' => '%'.$lastname.'%']] 
       ]) 
       ->order(['Lessons.lesson_date' => 'ASC']) 
       ->hydrate(true);
