php - 验证规则 unique 至少需要 1 个参数

Question

我的 laravel 有问题我不能发布数据

一个错误说

InvalidArgumentException in Validator.php line 2593:
Validation rule unique requires at least 1 parameters.

这是我的代码

public function postUbah(Request $request, $id)

    $validator  = Validator::make($request->all(), [
            'username'  => 'required|unique:user|min:5',
            'name'      => 'required',
            'group'     => 'required'
        ]);
}

感谢您的帮助。

这是我的模型

class User extends Model implements AuthenticatableContract, CanResetPasswordContract {

    use Authenticatable, CanResetPassword;


    protected $table = 'user';


    protected $fillable = ['username', 'password'];


    protected $hidden = ['password', 'remember_token'];

您忘记在验证规则中添加参数来指定在验证规则中应该唯一的数据库表列。你可以这样做，

 $validator  = Validator::make($request->all(), [
        'username'  => 'required|unique:user,name|min:5',
        'name'      => 'required',
        'group'     => 'required'
    ]);
