/**

Answer 1

You need to fix this
public function User(){
return $this->belongsTo('App\Models\User');
}
here fix namespace app to App like that you need to fix all

Answer 2

namespace App\Models;
use Illuminate\Contracts\Auth\MustVerifyEmail;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Relations\HasOne;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Illuminate\Notifications\Notifiable;
class User extends Authenticatable
{
use HasFactory, Notifiable;
/**
* The attributes that are mass assignable.
*
* #var array
*/
protected $fillable = [
'name',
'email',
'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 Phone(){
return $this->hasOne('App\Models\Phone');
//Better to use ::class notation for greater benefits with IDE
//return $this->hasOne(Phone::class);
}
}
<?php
namespace App\Models;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
class Phone extends Model
{
use HasFactory;
protected $table = "phones";
public function User(){
return $this->belongsTo('App\Models\User');
//Better to use ::class notation for greater benefits with IDE
//return $this->hasOne(User::class);
}
}
Folder/directory is app but the namespace is App
So need to change app\Models\Phone and app\Models\User to App\Models\Phone and App\Models\User
Better yet, use ::class notation for greater benefits with IDE - like easy navigation - not possible with string literals.
So instead of string literal App\Models\Phone import use App\Models\Phone statement and the Phone::class
Similarly for User import use App\Models\User and then use User::class
