Target class [ 〇ed Seeder] does not exist. does not resolve the issue.

Asked 3 months ago, Updated 3 months ago, 9 views

I'm running the laravel app on my mac.I tried to use Ravel's seeder function, so I wrote the code, but it didn't work and the following error occurred.Thank you for your cooperation.

The error statement is as follows

 code
$ phpartisan db:seed

Deprecated: PHP Startup: Use of mbstring.internal_encoding is deprecated in Unknown on line 0

   Illuminate\Contracts\Container\BindingResolutionException 

  Target class [PhotoTableSeeder] does not exist.

I don't know why, but I think it's because I can't read PhotoTableSeeder and it doesn't exist.
I tried to erase the cache and run one of the solutions, the , but it didn't work.

 code
phpartisan cache —clear
phpartisan config —Clear
phpartisan route —clear
phpartisan view —Clear
composer dump-autoload

As a procedure for using the seeder function, I first created the seeder in artisan and described it as follows:

<?php

namespace Database\Seeders;

use Illuminate\Database\Console\Seeds\WithoutModelEvents;
use Illuminate\Database\Seeder;


// addition
use Illuminate\Support\str;
use App\User;


// Added (20220623)
use Illuminate\Support\Facades\DB;

class PhotoTableSeeder extensions Seeder
{
    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {
        // Added (20220623)
        $param=[
            'user_id'=>fn()=>\App\User::factory()->create()->id,
            'filename' = > Str::random(12).'.jpg',
            'created_at' = > now(),
            'updated_at' = > now(),
        ];
        DB::table('photos') - > insert($param);
    }
}

Next, I wrote this to register the seeder file.

<?php

use Illuminate\Database\Seeder;

class DatabaseSeeder extensions Seeder
{
    /**
     * Seed the application's database.
     *
     * @return void
     */
    public function run()
    {
        $this->call(PhotoTableSeeder::class);
    }
}

php laravel

Terateil has solved the problem.In conclusion, it was an error due to the disappearance of the namespace part, which was written by default.Thank you!
