Unknown column 'username' in Laravel

问题

Been trying to solve this for 2 days now.

When I try to seed user data to my database, I get:

SQLSTATE[42S22]: Column not found: 1054 Unknown column 'username' in 'field list' (SQL: insert into users (name, username, password, email, updated_at, created_at) values (tony, tony_admin, $2y$10$lBDvjtEu.tYueU
AuRutTteHLmOntXSBAZsX.tO.ZK3RtxwiLXOBGW, tony_admin@laravel.com, 2018-02-18 00:12:39, 2018-02-18 00:12:39))

User.php

class User extends Authenticatable
{
    use Notifiable;
    protected $fillable = [
        'name', 'username', 'email', 'password',
    ];
    protected $hidden = [
        'password', 'remember_token',
    ];
}

Create users migration file

class CreateUsersTable extends Migration
{

    public function up()
    {
        Schema::create('users', function (Blueprint $table) {
            $table->increments('id');
            $table->string('name');
            $table->string('email')->unique();
            $table->string('username')->unique();
            $table->string('password');
            $table->rememberToken();
            $table->timestamps();
        });
    }

    public function down()
    {
        Schema::dropIfExists('users');
    }
}

Register controller

class RegisterController extends Controller
{

    use RegistersUsers;

    protected $redirectTo = '/home';

    public function __construct()
    {
        $this->middleware('guest');
    }

    protected function validator(array $data)
    {
        return Validator::make($data, [
            'name' => 'required|string|max:255',
            'username' => 'required|string|max:255|unique:users',
            'email' => 'required|string|email|max:255|unique:users',
            'password' => 'required|string|min:6|confirmed',
        ]);
    }

    protected function create(array $data)
    {
        return User::create([
            'name' => $data['name'],
            'username' => $data['username'],
            'email' => $data['email'],
            'password' => bcrypt($data['password']),
        ]);
    }
}

Database seeders

class DatabaseSeeder extends Seeder
{

    public function run()
    {
        Model::unguard();
        $this->call(UsersTableSeeder::class);
        $this->command->info("Users table seeded :)");
        Model::reguard();
    }
}

class UsersTableSeeder extends Seeder
{
    public function run()
    {
        User::create(array(
            'name' => 'tony',
            'username' => 'tony_admin',
            'password' => Hash::make('admin'),
            'email' => 'tony_admin@laravel.com'
        ));
    }
}

I've tried searching for answers, but all the similar questions seem to trying to use foreign keys, whereas I'm just trying to add a username field to the default user class.

I'm using Laravel version 5.5.34. What's going on here?

回答1:

People keep answering this with wrong answers so I'm going to post the answer that I got in the comments which worked. I was trying to add the username column with the same migration file which had already ran. I needed to create a new migration file to update the users table and add the usernamecolumn. Migration files can only be run once in laravel.

Run this all in CMD

php artisan view:clear

php artisan cache:clear

php artisan debugbar:clear

composer dump-autoload

php artisan log:clear

Perhaps you can use this :

    DB::table('users')
    ->insert([
        'name' => 'tony',
        'username' => 'tony_admin',
        'password' => Hash::make('admin'),
        'email' => 'tony_admin@laravel.com'
    ]);
