database - 如何在 Laravel 中创建数据库模式(表)？

Question

我是 Laravel 的新手。我正在尝试在 Laravel 中创建数据库。我在控制台中尝试过:

Schema::create

但它给出“找不到命令”。我应该安装什么或如何创建数据库？

我的工作示例:

创建新工匠命令:

php artisan make:command mysql

App\Console\Commands\mysql.php 的内容:

namespace App\Console\Commands;

use Illuminate\Console\Command;
use Illuminate\Support\Facades\DB;

class mysql extends Command
{
    /**
     * The name and signature of the console command.
     *
     * @var string
     */
    protected $signature = 'mysql:createdb {name?}';

    /**
     * The console command description.
     *
     * @var string
     */
    protected $description = 'Create a new mysql database schema based on the database config file';

    /**
     * Create a new command instance.
     *
     * @return void
     */
    public function __construct()
    {
        parent::__construct();
    }

    /**
     * Execute the console command.
     *
     * @return mixed
     */
    public function handle()
    {
        $schemaName = $this->argument('name') ?: config("database.connections.mysql.database");
        $charset = config("database.connections.mysql.charset",'utf8mb4');
        $collation = config("database.connections.mysql.collation",'utf8mb4_unicode_ci');

        config(["database.connections.mysql.database" => null]);

        $query = "CREATE DATABASE IF NOT EXISTS $schemaName CHARACTER SET $charset COLLATE $collation;";

        DB::statement($query);

        config(["database.connections.mysql.database" => $schemaName]);

    }
}

然后运行:(schema_name 是可选的)

php artisan mysql:createdb schema_name
