How to get the content of additional fields of the intermediate table in Laravel orm many-to-many relationship?

Question

    id
questions
    id
user_questions
    user_id
    question_id

    unique(user_id, question_id)

Answer 1

It looks roughly like this, when defining model relationships

return $this->belongsToMany('App\Role')->withPivot('column1', 'column2');

When getting data

$user = App\User::find(1);

foreach ($user->roles as $role) {
    echo $role->pivot->column1;
}
