I'm trying to do this by using (the observer), I did all steps correctly but the issue is:
when (card model) updated his children still exist in the middle table of the relationship, I want to remove them when any update on the card.
Route:
Route::get('/test',function(){
$card = \App\Models\Card::find(1);
$card-> update([
'name' => 'firstCard1',
'user_name' =>1,
]);
return true;
});

{
public function updated(Card $card)
{
$card -> contact()-> delete();

For the timestamps for the pivot you would call the "method" withTimestamps() not a "property" named withTimestamps:
// Video
public function categories()
{
return $this->belongsToMany(Category::class)->withTimestamps();
}
// Category
public function videos()
{
return $this->belongsToMany(Video::class)->withTimestamps();
}
I need to get data from the teaching_subjects table to my Vue file according to teacher table data. I have created the relationship with the TeachingSubject model and Teacher model.
This is my Teacher Model,
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Teacher extends Model
{
protected $table = 'teacher';
protected $fillable = [
'firstName',
'lastName',
'teacherUserName',

'description',
'speakEnglish',

'password',
'status',
];
public function approvalStatus(){
return $this->belongsTo(ApprovalStatus::class);
}
public function teachingSubject(){
return $this->hasMany(Teacher::class);
}
}
And this is my TeachingSubject Model
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class TeachingSubject extends Model
{
protected $table = 'teaching_subjects';
protected $fillable = [
'teacher_id',
'subject_id',
'lesson_fee'
];
public function teacher(){
return $this->hasMany(Teacher::class);
}
public function subject(){
return hasMany(Subject::class);
}
}
This is my Subject model,
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Subject extends Model
{
protected $table = 'subject';
protected $fillable = [
'subject',
'grade_id',
'no_of_teachers',
'status'
];
public function teachingSubject(){
return belongsTo(TeachingSubject::class);
}
}
This is my Teching_subjects migration file
<?php
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;
class CreateTeachingSubjectsTable extends Migration
{
/**
* Run the migrations.

I need to get the date(created_at), teacher_name, lesson and lesson_fee using TeachingSubjectController.
for example if You want to get user that made the comment, so get that user from the comment object.
Try this
$user = User::find(1);
$posts = $user->posts;
foreach ($posts as $post) {
foreach ($post->comments as $comment) {
echo $comment->commentcontent;
echo $comment->users;
}
}
I have an user model and a student model which I have created relationship for, but when I try to
$student->user->fullname
I get this error

}
public function topics()
{
return $this->hasMany(Topic::class);
}
public function levels()
{
return $this->hasMany(Level::class);
}
}
and here is my student model code
<?php
namespace App\Model;
use App\User;
use App\Model\Course;
use App\Assignment;
use App\Level;
use App\Model\DoneQuiz;
use App\Model\Teacher;

}
public function guardian()
{
return $this->hasOne(Guardian::class);
}
public function donequizzes()
{

}
and even when I try to use this relationship to get data like
'student_id' => auth()->user()->student()->id
I get this error
"BadMethodCallException Call to undefined method
Illuminate\Database\Eloquent\Relations\BelongsTo::id()"
when you use student() it returns a query builder
Either change it to simple student
'student_id' => auth()->user()->student->id
OR
'student_id' => auth()->user()->student()->first()->id

I think you could try to delete related model in the controller before the user, i.e.:
public function delete($id)
{
$profile = User::find($id);
$profile->posts()->delete();
$profile->delete();
Session::flash('remove', "The profile was successfully deleted!");
return redirect('login');
}
Or you can go with model event, i.e.:
protected static function boot() {
parent::boot();
static::created(function ($user) {
$user->profile()->create([
'title' => $user->username,
]);
});
static::deleting(function($user) {
$user->posts()->delete();
});
}
