我的 laravel 版本是 5.0。我已经运行了 php artisan make:seeder SettingTableSeeder。

Answer 1

php artisan make:seeder 命令是在 Laravel 5.1 中引入的，因此在 Laravel 5.0 中将无法使用

您需要运行另一个命令:

To seed your database, you may use the db:seed command on the Artisan CLI: php artisan db:seed

By default, the db:seed command runs the DatabaseSeeder class, which may be used to call other seed classes. However, you may use the --class option to specify a specific seeder class to run individually: php artisan db:seed --class=UserTableSeeder

You may also seed your database using the migrate:refresh command, which will also rollback and re-run all of your migrations: php artisan migrate:refresh --seed

如何创建种子

Laravel also includes a simple way to seed your database with test data using seed classes. All seed classes are stored in database/seeds. Seed classes may have any name you wish, but probably should follow some sensible convention, such as UserTableSeeder, etc. By default, a DatabaseSeeder class is defined for you. From this class, you may use the call method to run other seed classes, allowing you to control the seeding order.

将其添加到 database/seeds/seedsfilename.php 中的文件中。

class DatabaseSeeder extends Seeder {

    public function run()
    {
        $this->call('UserTableSeeder');

        $this->command->info('User table seeded!');
    }

}

class UserTableSeeder extends Seeder {

    public function run()
    {
        DB::table('users')->delete();

        User::create(['email' => 'foo@bar.com']);
    }

}

之后您需要运行 composer dump-autoload 或 composer dumpautoload(它的作用相同，但只是另一个名称)。
