Unknown column 'User.first_name' in 'where clause' cakePHP - php

Question

I have tutor_students and users table. tutor_studentscontains id, tutor_id, student_id and created. users contain id, user_id, role_id, email, first_name, last_name. tutor_students table is connected table between tutor and student. so tutor can see their student list and can add new student too.
I succeeded to display student list and add new student to tutor student list. but when i want to search student, there will be an error:
Error: SQLSTATE[42S22]: Column not found: 1054 Unknown column

Answer 1

You need to contain the User model in your find query:-
$this->TutorStudent->find('all', array(
'conditions' => $filters,
'contain' => array('User')
);

Answer 2

The table User is not included in the query, you should try something like:
SELECT TutorStudent.id, TutorStudent.tutor_id, TutorStudent.student_id, TutorStudent.created
FROM virlen.tutor_students AS TutorStudent join
virlen.User as user
on user.id = tutorstudent.student_id
WHERE TutorStudent.tutor_id IS NULL AND User.email LIKE '%ka#mailinator.com%';
This assuming that the User table key used in tutor_student.student_id is id and not user_id, in which case you should change your code consequently to be it like: on user.user_id = tutorstudent.student_id

Answer 3

the from clause should be
virlen.tutor_students AS TutorStudent,virlen.users AS User
Then your query should be
SELECT TutorStudent.id, TutorStudent.tutor_id, TutorStudent.student_id, TutorStudent.created FROM virlen.tutor_students AS TutorStudent,virlen.users AS User WHERE TutorStudent.tutor_id IS NULL AND User.email LIKE '%ka#mailinator.com%'
Your code should be
$my_tutor_list = $this->TutorStudent->find('all',array('conditions'=>$filters,'contain' => array('User')));
if(!empty($my_tutor_list))
{
foreach($my_tutor_list as $key=>$value)
{
$user_list[] = $value['TutorStudent']['student_id'];
}
}
