我尝试使用Livewire绑定直接到模型属性，我得到这个错误，有人帮助吗？先谢谢你。
在初始化之前，不能访问类型化属性App\Http\Livewire\V2\Settings\Locations：：$country

class Locations extends Component{
  public Country $country;
  use WithPagination;
  protected $rules = [
    'country.name' => 'required|min:100',
    'country.note' => 'required|min:100',
  ];

  public function SaveCountry(){
    $this->validate();
    $this->country->save();
    $this->reset();
    session()->flash('info','The country have been added successful.');
  }
 public function render(){
    return view('livewire.v2.settings.locations',[
        'countries' => Country::orderBy('order_num','desc')->paginate(10),
    ]);
  }
}
