Laravel Class 'Тype' not found

Question

Using laravel, I have products page with few categories. When I create a new product and click save it is giving me an error:

Class 'Тype' not found

`protected function newRelatedInstance($class)
    {
        return tap(new $class, function ($instance) {
            if (! $instance->getConnectionName()) {
                $instance->setConnection($this->connection);
            }
        });
    }`

Despite the error the date is saved into the datebase and appear into the products list page.

Answer 1

There is no class named Type. You are referring to a model name in those relationships. When referencing classes as strings, they are fully qualified names.

Type is the fully qualified name for the class Type in the root namespace. There is no class in the root namespace named Type.

I bet you have a App\Models\Type though.

This is another reason to use the class constant and not string literals yourself, Class::class.

Answer 2

<?php

namespace App\Models;
use Illuminate\Database\Eloquent\Model;
use Backpack\CRUD\CrudTrait;
class Type extends Model
{
  use CrudTrait;

/*
|--------------------------------------------------------------------------
| GLOBAL VARIABLES
|--------------------------------------------------------------------------
*/

protected $table = 'types';
// protected $primaryKey = 'id';
// public $timestamps = false;
// protected $guarded = ['id'];
protected $fillable = ['name'];
// protected $hidden = [];
// protected $dates = [];

/*
|--------------------------------------------------------------------------
| FUNCTIONS
|--------------------------------------------------------------------------
*/

/*
|--------------------------------------------------------------------------
| RELATIONS
|--------------------------------------------------------------------------
*/

public function product() {

    return $this->hasMany('Product');

  }
}

I think you are missing one closing paranthesis in the type class which is causing the issue. Please check if you are using the close } for the class properly.
