Can't call to model - php

Question

Vehicle.php ( app\Vehicle.php file )
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Vehicles extends Model
{
protected $primaryKey = 'serie';
protected $fillable = ['serie', 'color', 'power', 'capacity', 'speed'];
protected $hidden = ['serie'];
public function maker()
{
return $this->belongsTo('Maker');
}
}
VehicleController.php
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Http\Requests;
use App\Vehicle;
class VehicleController extends Controller
{
public function index()
{
$vehicles = Vehicle::all();
return response()->json(['data'=> $vehicles], 200);
}
}
Below is my route list

when I call to myapp.com/vehicles, it show me 'Class 'App\Vehicle' not found' error. I have also Maker controller and Maker model. I can call myapp.com/makers and it also return properly. Please point me where is my weakness.

Answer 1

You named your class Vehicles not Vehicle. You should name it Vehicle make sure it is Vehicle.php and you will be fine.
The relationship should have the Fully Qualified Class Name in it as well:
public function maker()
{
return $this->belongsTo('App\Maker');
// or
return $this->belongsTo(Maker::class);
// assuming they are in the same namespace
}
