$validatedData = $request->validate([

return redirect('/ajoutercategorie')->with('status', 'La catégorie'
.$categorie->category_name.'a été ajoutée avec succès');

use Illuminate\Database\Eloquent\Model;
class Categorie extends Model
{
use HasFactory;
protected $fillable = ['category_name'];
}
my table name is "categories". This is my table
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;
class CreateCategoriesTable extends Migration
{
/**
* Run the migrations.
*
* #return void
*/
public function up()
{
Schema::create('categories', function (Blueprint $table) {
$table->id();
$table->string('categorie_name');
$table->timestamps();
});
}
/**
* Reverse the migrations.
*
* #return void
*/
public function down()
{
Schema::dropIfExists('categories');
}
}
Need helps to solve that, thanks.

Answer 1

Your controller calling
$categorie = Categorie::ajoutercategorie($validatedData);
which is calling ajoutercategorie function on your Model, but you don't have that function on model.
You can change :
public function sauvercategorie(Request $request){
$validatedData = $request->validate([
'category_name' => 'required | max:255',
]);
$categorie = Categorie::ajoutercategorie($validatedData);
return redirect('/ajoutercategorie')->with('status', 'La catégorie'
.$categorie->category_name.'a été ajoutée avec succès');
into :
public function sauvercategorie(Request $request){
$validatedData = $request->validate([
'category_name' => 'required | max:255',
]);
$categorie = Categorie::create($validatedData);
return redirect('/ajoutercategorie')->with('status', 'La catégorie'
.$categorie->category_name.'a été ajoutée avec succès');
Or you can see this documentation https://laravel.com/docs/9.x/eloquent#inserting-and-updating-models for default function CRUD
