Laravel 5 - artisan seed [ReflectionException] Class SongsTableSeeder does not exist

When I run php artisan db:seed I am getting the following error:

[ReflectionException] Class SongsTableSeeder does not exist

What is going on?

My DatabaseSeeder class:

<?php

use Illuminate\Database\Seeder;
use Illuminate\Database\Eloquent\Model;

class DatabaseSeeder extends Seeder {

	/**
	 * Run the database seeds.
	 *
	 * @return void
	 */
	public function run()
	{
		Model::unguard();

		$this->call('SongsTableSeeder');
	}

}

My SongsTableSeeder class:

<?php

// Composer: "fzaninotto/faker": "v1.4.0"
use Faker\Factory as Faker;
use Illuminate\Database\Seeder;
use DB;

class SongsTableSeeder extends Seeder {

	public function run()
	{
		$faker = Faker::create();
		$songs = [];
		foreach(range(1, 10) as $index)
		{
			$songs[] = ['title' => $faker->words(rand(1,4))];
		}

		DB::table('songs')->insert($songs);

	}

}

You need to put SongsTableSeeder into file SongsTableSeeder.php in the same directory where you have your DatabaseSeeder.php file.

And you need to run in your console:

composer dump-autoload

to generate new class map and then run:

php artisan db:seed

I've just tested it. It is working without a problem in Laravel 5

I solved it by doing this:

1. Copy the file content.
2. Remove file.
3. Run command: php artisan make:seeder .
4. Copy the file content back in this file.

This happened because I made a change in the filename. I don't know why it didn't work after the change.

File SongsTableSeeder.php should be in database/seeds directory or in its subdirectory.

You need to run:

composer dump-autoload

and then:

php artisan db:seed

or:

php artisan db:seed --class=SongsTableSeeder

If you migrated to Laravel 8, you have to add a namespace to the seeders class:

<?php

namespace Database\Seeders;

...

Next, in your composer.json file, remove classmap block from the autoload section and add the new namespaced class directory mappings:

"autoload": {
    "psr-4": {
        "App\\": "app/",
        "Database\\Seeders\\": "database/seeds/"
    }
},

An finally, do a composer dump-autoload.

For more information: https://laravel.com/docs/8.x/upgrade#seeder-factory-namespaces

SongsTableSeeder.php should be in database/seeds directory

Console command steps:

composer dump-autoload

and then:

php artisan cache:clear

and then:

php artisan optimize

and then:

php artisan db:seed

or:

php artisan db:seed --class=SongsTableSeeder

I'm running the very latest Laravel 5 dev release, and if you've changed the namespace you'll need to call your seed class like this:

$this->call('\todoparrot\TodolistTableSeeder');

Obviously you'll need to replace todoparrot with your designated namespace. Otherwise I receive the same error indicated in the original question.

Do not forgot that the composer dump-autoload works in relation with the autoload / classmap section of composer.json. Take care about that if you need to change seeders directory or use multiple directories to store seeders.

"autoload": {
    "classmap": [
      "database/seeds",
      "database/factories"
    ],
},

You probably specify the .php extension and It don't found your class.

What I was doing :

php artisan db:seed --class=RolesPermissionsTableSeeder.php

What solved my problem : What I was doing :

php artisan db:seed --class=RolesPermissionsTableSeeder

If our CustomTableSeeder is in same directory with DatabaseSeeder we should use like below:

$this->call('database\seeds\CustomTableSeeder');

in our DatabaseSeeder File; then another error will be thrown that says: 'DB Class not found' then we should add our DB facade to our CustomTableSeeder File like below:

use Illuminate\Support\Facades\DB;

it worked for me!

I have used only SINGLE FILE with TWO classes in it following :

use Illuminate\Database\Seeder;
use Illuminate\Database\Eloquent\Model;
use App\Lesson;

use Faker\Factory as Faker;

class DatabaseSeeder extends Seeder {

/**
 * Run the database seeds.
 *
 * @return void
 */
public function run()
{
	//Lesson::truncate();
				
	Model::unguard();

	$this->call("LessonsTableSeeder");
	

}

}

class LessonsTableSeeder extends Seeder {

/**
 * Run the database seeds.
 *
 * @return void
 */
public function run()
{
	
	$faker = Faker::create();

	foreach(range(1,30) as $index) {
		
		Lesson::create(['title' => $faker->sentence(5), 'body' => $faker->paragraph(4)]);
		
	}
	
}

}

If you have copied the seeders files from any other project then you need to run the artisan command php artisan db:seed otherwise it is fine.

i got [ReflectionException] Class Seeder does not exist too and when i use composer dump-autoload, i got an error preg_match(): JIT compilation failed: no more memory when i run it.

What i did is that i change ;pcre.jit=1 to pcre.jit=Off in php.ini! You can find the path by using php --ini in your terminal!

I am using mac with php 7.3! Hope that help any of you guys out there!

When you migrate your project to Laravel 8 and you get that error then you should follow some steps given below.

1.Go to your composer.json file.

2.Change autoload section

"autoload": {
    "psr-4": {
        "App\\": "app/",
         "Database\\Factories\\": "database/factories/",
         "Database\\Seeders\\": "database/seeders/"
     }
 },

to

"autoload": {
     "psr-4": {
         "App\\": "app/"
      },
      "classmap": [
         "database/seeds",
         "database/factories"
      ]
},

3.Now run the command of composer dump-autoload or composer update

4.And last run command of php artisan db:seed

I had the same "reflection exception" error. The solution was to copy the class file to the server, from dev, for me. dumb mistake, but given how many files we deal with its easy to forget to copy them over to the server every time.
