Call to undefined method App\Models\BrandCodeModell::fromRawAttributes() in Laravel - php

Question

I have a model called BrandCodeModell :
<?php
namespace App\Models;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
class BrandCodeModell extends Model
{
use HasFactory;
public function brand()
{
return $this->belongsTo(Brand::class, 'brand_id', 'id');
}
public function modell()
{
return $this->belongsTo(Modell::class, 'modell_id', 'id');
}
public function codeModell()
{
return $this->belongsTo(CodeModell::class, 'code_id', 'id');
}
}
And this is Modell relation with Brand Model :
public function modells()
{
return $this->belongsToMany(Modell::class)->using(BrandCodeModell::class)
->withPivot('code_id');
}
When I try too add new modell to database I get this error :
BadMethodCallException
Call to undefined method App\Models\BrandCodeModell::fromRawAttributes()
Here is my controller to save modell to database :
$brand = Brand::where('id', $id)->first();
$brand->modells()->detach();
$modells = collect($request['modells']);
$modells->each(function ($item) use ($brand) {
if (is_null($item['name'])) return;
$mod = Modell::firstOrCreate([
'name' => $item['name'],
'sort' => $item['sort']
]);
$mod_code = $mod->codeModell()->firstOrCreate([
'name' => $item['code']
]);
$brand->modells()->attach($mod->id, [
'code_id' => $mod_code->id
]);
});
In this code, Modell::firstOrCreate and $mod_code = $mod->codeModell()->firstOrCreate will be create successfully but this part of code $brand->modells()->attach($mod->id, ['code_id' => $mod_code->id]); does not work.
Where is the problem ?
Tell me if you need more details

Per the documentation:
Custom many-to-many pivot models should extend the Illuminate\Database\Eloquent\Relations\Pivot class
So your pivot class should look like this:
<?php
namespace App\Models;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Relations\Pivot;
class BrandCodeModell extends Pivot
{
//
}
However, unless you're adding additional methods on to the pivot class, there's no need to define it; Laravel will automatically use the appropriate pivot table. Likewise there's probably no need for it to import the HasFactory trait, as entries would be automatically created by related model creation.
