Question

我的laravel有问题我无法发布数据

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。

这是我的模特

class User extends Model implements AuthenticatableContract, CanResetPasswordContract {

    use Authenticatable, CanResetPassword;


    protected $table = 'user';


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


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

Answer 1

您忘记在验证规则中添加参数，以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'
    ]);

Answer 2

为什么不像这样使用

L5.5

public function postUbah(Request $request, $id)

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

L5.4

public function postUbah(Request $request, $id)
    $validator  = $this->validate($request, [
            'username'  => 'required|unique:user|min:5',
            'name'      => 'required',
            'group'     => 'required'
        ]);
}

我知道您的表名是user ..请确保您的用户模型

class User {
    protected $table = "user";
}

验证规则唯一需要至少1个参数
