Laravel 5-如何在没有电子邮件确认的情况下进行身份验证

我正在Laravel 5中创建一个简单的身份验证系统。我有用Laravel 4编写的身份验证代码，我正在使用它作为基础。

我的问题是

SQLSTATE[42S22]：未找到列：1054中的未知列"已确认"where子句"（SQL：从users中选择*，其中email=myemail@gmail.com并且confirmed＝1极限1）

看起来Laravel正在查看我的电子邮件是否经过验证。但我不需要为这个应用程序执行注册和验证过程。我的问题是，我如何告诉laravel不要担心电子邮件确认？

我的身份验证代码如下：

public function postAuthenticate()
{
    // Fetch posted credentials
    $email = 'Request::input('email');
    $password = 'Request::input('password');
    $remember = 'Request::has('_remember');
    $credentials = [
        'email' => $email,
        'password' => $password,
        'confirmed' => 1
    ];
    // Attempt to log in user
    if ('Auth::attempt($credentials, $remember))
    {
        return 'Redirect::intended('dashboard');
    }
    // If this code was reached, it means that the user failed to authenticated.  
    // In this case, redirect back to the login page with errors.
    $messages = new Illuminate'Support'MessageBag;
    $messages->add('Authentication Error', 'Sign in failed.');

    return 'Redirect::to('/login')
        ->withInput()   
        ->with('errors', $messages);
}

我的用户模型看起来像：

<?php namespace App;
use Illuminate'Auth'Authenticatable;
use Illuminate'Database'Eloquent'Model;
use Illuminate'Auth'Passwords'CanResetPassword;
use Illuminate'Contracts'Auth'Authenticatable as AuthenticatableContract;
use Illuminate'Contracts'Auth'CanResetPassword as CanResetPasswordContract;
class User extends Model implements AuthenticatableContract, CanResetPasswordContract {
    use Authenticatable, CanResetPassword;
    /**
     * The database table used by the model.
     *
     * @var string
     */
    protected $table = 'users';
    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = ['name', 'email', 'password'];
    /**
     * The attributes excluded from the model's JSON form.
     *
     * @var array
     */
    protected $hidden = ['password', 'remember_token'];
}

最后，我的用户表迁移是：

<?php
use Illuminate'Database'Schema'Blueprint;
use Illuminate'Database'Migrations'Migration;
class CreateUsersTable extends Migration {
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('users', function(Blueprint $table)
        {
            $table->increments('id');
            $table->string('name');
            $table->string('email')->unique();
            $table->string('password', 60);
            $table->rememberToken();
            $table->timestamps();
        });
    }
    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::drop('users');
    }
}

谢谢！
