Question

我正在为每个有记录的用户创建一个数据库。我可以通过config设置此创建的数据库。但是我不能迁移。我遇到的错误是：

未配置数据库[5d7acdf5adf6a]。

    $user=User::create([
        'name' => $data['name'],
        'email' => $data['email'],
        'password' => Hash::make($data['password']),
        'database'=>uniqid()
    ]);

     Artisan::call('make:database',['dbname'=>$user->database]);
     $this->connectAnother($user->database);

     Artisan::call('migrate',['--database'=>$user->database]);
     dd(Artisan::output());
     error-->Database [5d7acdf5adf6a] not configured.

connectAnother是我编写的一种方法。

    public function connectAnother($database){
            \Config::set("database.connections.mysql", [
            "host" => "127.0.0.1",
            "database" => $database,
            "username" => "...",
            "password" => "..."
        ]);
    }

config / database.php：

    'mysql' => [
        'driver' => 'mysql',
        'url' => env('DATABASE_URL'),
        'host' => env('DB_HOST', '127.0.0.1'),
        'port' => env('DB_PORT', '3306'),
        'database' => env('DB_DATABASE', 'forge'),
        'username' => env('DB_USERNAME', 'forge'),
        'password' => env('DB_PASSWORD', ''),
        'unix_socket' => env('DB_SOCKET', ''),
        'charset' => 'utf8mb4',
        'collation' => 'utf8mb4_unicode_ci',
        'prefix' => '',
        'prefix_indexes' => true,
        'strict' => true,
        'engine' => null,
        'options' => extension_loaded('pdo_mysql') ? array_filter([
            PDO::MYSQL_ATTR_SSL_CA => env('MYSQL_ATTR_SSL_CA'),
        ]) : [],
    ],

我尝试在更改数据库时直接进行迁移，但是得到的答案是“什么都不需要迁移”

这是解决方案

 public function connect($database){
    $connection = [
        'driver' => 'mysql',
        'url' => config('database.connections.mysql.url'),
        'host' => config('database.connections.mysql.host'),
        'port' => config('database.connections.mysql.port'),
        'database' => $database,
        'username' => config('database.connections.mysql.username'),
        'password' => config('database.connections.mysql.password'),
        'unix_socket' => env('DB_SOCKET', ''),
        'charset' => 'utf8mb4',
        'collation' => 'utf8mb4_unicode_ci',
        'prefix' => '',
        'prefix_indexes' => true,
        'strict' => true,
        'engine' => 'InnoDB',
        'options' => extension_loaded('pdo_mysql') ? array_filter([
            PDO::MYSQL_ATTR_SSL_CA => env('MYSQL_ATTR_SSL_CA'),
        ]) : [],
    ];
    \Config::set("database.connections.{$database}", $connection);
    DB::setDefaultConnection($database);->***The most important place in this line***

我无法使用Laravel动态迁移
