How to add to my Index/Show, so that it displays a table, from another table. (Laravel)

First post here, hope all is well with everyone! I am working on my senior project and struggling with this concept. Maybe it isn’t possible, or it is and I’m thinking about it the wrong way.

I currently have this- This displays the student, with all its foreign keys in the other tables. In settings, there is a foreign key ‘conversion_id.’, I would like settings on the student call(code below) to ALSO display the conversion table, from the FK in settings.

$student = Student::with('studentIntroSurveys', 'settings', 'giftsSurveyResults', 
'studentGiftSurveys', 'devotionals', )->get();

If this does not make sense, I am sorry. I am still l new to the language.

(Code to display students. It shows settings, but not the conversions within settings.)

$student = Student::with('studentIntroSurveys', 'settings', 'giftsSurveyResults',
'studentGiftSurveys', 'devotionals', )->get();

if (!$student) {
    return response('No Data', 400);
} else {
    return response($student);
}

I would like it to display this settings, but WITH the conversion_id table!!
What it displays =

settings: { setting_id: 4, student_id: 1, dark_mode: 1, conversion_id: 1, 
notification_enabled: 1, notification_time: "08:00:00" } `

my has-one method =

public function settings()
{
    $settings = $this->hasOne(Settings::class, 'student_id', 'student_id');
    return $settings;
}

>Solution :

You can use the dot syntax for nested eager loading: 'settings.conversation' e.g.

$student = Student::with('studentIntroSurveys', 'settings.conversation', 'giftsSurveyResults', 'studentGiftSurveys', 'devotionals', )->get();

Alternatively, you could set up a belongsToMany relationship on the Student model and use settings as the pivot table:

public function conversations()
{
    return $this->belongsToMany(Conversation::class, 'settings')
}

Just a few FYIs:

Your if statement is never going to return the 400 response as $student is always going to be a collection. You could instead do if ($student->isEmpty()).

I would also recommend changing the variable to $students as it will be a collection of students rather than a single student.

You can simple your settings relationship by removing the temporary variable and just returning the relationship:

public function settings()
{
    return $this->hasOne(Settings::class, 'student_id', 'student_id');
}
