Laravel - 完整性约束违规:1062重复输入

Question

当我尝试在我的数据库中创建新用户时遇到问题,如果我在phpmyadmin中添加用户我没有问题,但是当我尝试在我的laravel web中创建用户时,用户创建了此错误:SQLSTATE [23000 ]:完整性约束违规:1062重复条目'15 .236.964-5'用于键'PRIMARY'我不知道哪个是问题,因为在数据库中不存在相同的主键.有问题的表是:

CREATE TABLE IF NOT EXISTS `users` (
`rut` varchar(255) COLLATE utf8_unicode_ci NOT NULL,
  `name` varchar(255) COLLATE utf8_unicode_ci NOT NULL,
  `email` varchar(255) COLLATE utf8_unicode_ci NOT NULL,
  `password` char(60) COLLATE utf8_unicode_ci NOT NULL,
  `edad` int(11) NOT NULL,
  `pais` varchar(255) COLLATE utf8_unicode_ci NOT NULL,
  `comuna` varchar(255) COLLATE utf8_unicode_ci NOT NULL,
  `sector` varchar(255) COLLATE utf8_unicode_ci NOT NULL,
  `tipo` enum('profesor','alumno','administrador_parrilla','administrador_sistema','externo') COLLATE utf8_unicode_ci NOT NULL,
  `remember_token` varchar(100) COLLATE utf8_unicode_ci DEFAULT NULL,
  `created_at` timestamp NULL DEFAULT NULL,
  `updated_at` timestamp NULL DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;

ALTER TABLE `users`
  ADD PRIMARY KEY (`rut`),
  ADD UNIQUE KEY `usuario_rut_unique` (`rut`),
  ADD UNIQUE KEY `usuario_email_unique` (`email`);

我的控制器:

class UsuarioController extends Controller
{
	public function index(){
        $users = User::All();
        return view('usuario.index', compact('users'));
    }

    public function create(){
    	return view('usuario.create');
    }
    public function store(Request $request) {
         User::create([
             'name' => $request['name'],
             'rut' => $request['rut'],
             'email' => $request['email'],
             'password' => bcrypt($request['password']),             
             'edad' => $request['edad'],
             'pais' => $request['pais'],
             'comuna' => $request['comuna'],
         ]);
        User::create($request->all());
        return redirect('/usuario')->with('message', 'store');
    }

    public function edit($rut){
        $user = User::find($rut);
        return view ('usuario.edit',['user'=>$user]);
    }

    public function update($id, Request $request){
        $user = User::find($id);
        $user -> fill($request->all());
        $user -> save();

        Session::flash('message', 'Usuario Editado Correctamente');
        return Redirect ('/usuario');
    }
}

我的型号:

class User extends Authenticatable
{
    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $table = "users";
    protected $fillable = [
        'rut', 'name', 'email', 'password', 'edad', 'pais', 'comuna', 'sector', 'tipo',
    ];
/**
    protected $primaryKey = 'rut';

    
     * The attributes that should be hidden for arrays.
     *
     * @var array
     */
    protected $hidden = [
        'password', 'remember_token',
    ];
}

我无法更改添加auto_increment的主键,因为我使用"Rut"作为主键,这是智利人的识别代码.

Answer 1

请执行以下步骤:

1)删除ADD UNIQUE KEY usuario_rut_unique (rut).

因为你已经定义了它rut是主键,所以PK总是唯一的(它的PKs行为)

2)在你的模型中定义rut主键,并禁用自动递增,因为它是varchar(不能int自然迭代):

/**
 * primaryKey 
 * 
 * @var integer
 * @access protected
 */
protected $primaryKey = 'rut'; 
/*
You cannot comment it to make in disabled, it will look for `id` param by default.
You cannot set it to be = null because in Your code You use ::find() function 
that looks for primaryKey.
 */

/**
 * Indicates if the IDs are auto-incrementing.
 *
 * @var bool
 */
public $incrementing = false;

3)删除此行:

User::create($request->all());

因为您已经在上一行中将记录插入数据库.

Answer 2

问题出在控制器中的一行代码。解决方案很简单，注释掉这一行：

User::create($request->all());

感谢您的回答。
