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
"trying to get property fullname of non-object"
here is my user model code:
<?php
namespace App;
use App\Assignment;
use App\Model\Quiz;
use App\Model\Course;
use App\Topic;
use App\Model\Guardian;
use App\Model\Student;
use App\Model\Teacher;
use Illuminate\Contracts\Auth\MustVerifyEmail;
use Illuminate\Database\Eloquent\SoftDeletes;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Illuminate\Notifications\Notifiable;
use Spatie\Permission\Traits\HasRoles;
class User extends Authenticatable implements MustVerifyEmail
{
use Notifiable, HasRoles, SoftDeletes;
/**
* The attributes that are mass assignable.
*
* @var array
*/
protected $fillable = [
'fullname',
'email',
'avatar',
'password',
];
/**
* The attributes that should be hidden for arrays.
*
* @var array
*/
protected $hidden = [
'password', 'remember_token',
];
/**
* The attributes that should be cast to native types.
*
* @var array
*/
protected $casts = [
'email_verified_at' => 'datetime',
];
public function setPasswordAttribute($password)
{
$this->attributes['password'] = bcrypt($password);
}
public function guardian()
{
return $this->belongsTo(Guardian::class);
}
public function teacher()
{
return $this->belongsTo(Teacher::class);
}
public function student()
{
return $this->belongsTo(Student::class);
}
public function assignments()
{
return $this->hasMany(Assignment::class);
}
public function quizzes()
{
return $this->hasMany(Quiz::class);
}
public function courses()
{
return $this->hasMany(Course::class);
}
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;
use App\Model\Guardian;
use Illuminate\Database\Eloquent\Model;
class Student extends Model
{
protected $fillable = ['user_id', 'level_id', 'guardian_id'];
public function user()
{
return $this->belongsTo(User::class);
}
public function courses()
{
return $this->hasMany(Course::class);
}
public function assignments()
{
return $this->hasMany(Assignment::class);
}
public function level()
{
return $this->hasOne(Level::class);
}
public function teachers()
{
return $this->hasMany(Teacher::class);
}
public function guardian()
{
return $this->hasOne(Guardian::class);
}
public function donequizzes()
{
return $this->hasMany(DoneQuiz::class);
}
}
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()"
