I just started working with a year old Laravel project for my fellowship and a major bug inhibiting progress is in the way. Any help would be greatly appreciated. Story below.

Once Laravel is up and running and I try to log in, I get this error:

Class User contains 3 abstract methods and must therefore be declared abstract or
implement the remaining methods 
(Illuminate\Auth\UserInterface::getRememberToken, 
Illuminate\Auth\UserInterface::setRememberToken,
Illuminate\Auth\UserInterface::getRememberTokenName)

I believed this could be fixed via http://laravel.com/docs/upgrade#upgrade-4.1.26 and so I added the following lines to my User as suggested:

public function getRememberToken(){ return $this->remember_token; }
public function setRememberToken($value){ $this->remember_token = $value; }
public function getRememberTokenName(){ return 'remember_token'; }

This got rid of the error but I still cannot log in. I'll use the correct information but it seems to redirect me back to the login page. Upon further research, I discovered that I may need to have a [b]remember_token[/b] field in my database. I attempted to add this and remigrate by adding:

$table->rememberToken(); 
[edit 2014-09-16, 07:05: added parens. they were in my code but forgotten in the post]

But that produced this stacktrace:

PHP Fatal error:  Call to undefined method Illuminate\Database\Schema\Blueprint::rememberToken() in /vagrant/www/vfamatching.dev/app/database/migrations/2013_11_01_033240_create_users_table.php on line 24

[edit 2014-09-16, 07:05: tried watcher's answer] After watcher's answer last night, I have tried using their solution by replacing

$table->rememberToken(); with
$table->string('remember_token', 100);

The migration no longer throws an error but the login still hangs. Also, I should point out that Laravel recommends using the rememberToken syntax

My login route

Route::get('login', array('as' => 'login', function () { return View::make('login'); }))->before('guest');
Route::post('login', 'UsersController@login');

and controller method

public function login() 
{ 
    $user = array(
        'email' => Input::get('email'),
        'password' => Input::get('password')
    );   
    if (Auth::attempt($user)) {
        Auth::user()->login();
        Auth::user()->lastLogin = Carbon::now();
        Auth::user()->save();
        if (Session::has('returnUrl'))
        {
            $intendedDestination = Session::get('returnUrl');
            Session::forget('returnUrl');
            return Redirect::to($intendedDestination)
            ->with('flash_success', 'You are successfully logged in.');
        }
        return Redirect::to('/')
            ->with('flash_success', 'You are successfully logged in.');
    }
    // authentication failure! lets go back to the login page
    return Redirect::route('login')
        ->with('flash_error', 'Your username/password combination was incorrect.')
        ->withInput();
}

'remember_token'只是一个varchar字段，应该像迁移中的任何其他字段一样创建：

$table->string('remember_token', 100)->nullable();

更新

作为对您的评论的回应，您是正确的，架构构建器文档确实允许该rememberToken方法，有趣的是升级指南没有提及它。它仅在 Laravel v4.2 及更高版本中可用，在撰写本文时，它只不过是上述代码的别名：

// File: /vendor/laravel/framework/src/Illuminate/Database/Schema/Blueprint.php
/**
 * Adds the `remember_token` column to the table.
 *
 * @return \Illuminate\Support\Fluent
 */
public function rememberToken()
{
    return $this->string('remember_token', 100)->nullable();
}

如果您使用的是 4.2 或更高版本，我会使用rememberToken函数而不是string函数来定义列，以防上面的函数定义在任何未来版本中发生更改。

至于您的登录尝试“挂起”，请使用相关的控制器方法更新您的问题，我也许可以进一步帮助您。

也许这只是一个小错误，rememberToken 是一个方法，应该这样调用：

$table->rememberToken();
