            'username'  => 'required|unique:user|min:5',

}

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'];

推荐答案

为什么不这样使用

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 ..确保您的用户模型具有

Im aware that your table name is user.. make sure your User Model have

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