Php 将参数（当前选定的$this->；user->；id，而不是auth（）->；user（）->；id）从视图传递到livewire+；拉维尔

我想将当前选定的用户id传递给livewire中的showmodal，每次尝试单击showmodal按钮时都会出现以下错误： 如果我删除{{$user->id}，showmodel会出现，但是当我提交输入的数据时，我得到了相同的错误，如： 这是我的模型数据方法： /***此组件中映射的模型*的数据

* * @return void */ 
public function modelData() 
{ 
    return [ 
        'user_id' => auth()->user()->id, 
        'related_id' => $this->user->id, 
        'treatment' => $this->treatment, 
        'sub_treatment' => $this->sub_treatment, 
        'status' => $this->status, 
    ]; 
}

创建方法：

/** * The create function. 
* * @return void */ 
public function create() 
{ 
     $this->validate(); 
     Appointment::create($this->modelData()); 
     $this->modalFormVisible = false; $this->reset(); 
}

创建显示模式为：

/** * Shows the create modal 
* * @return void */ 
public function createShowModal()  
{ 
      $this->resetValidation(); 
      $this->reset(); 
      $this->modalFormVisible = true; 
}

渲染方法如下所示：

public function render() 
{ 
     return view('livewire.user-appointments', [ 'data' => $this->read(), ]); 
}

模态关系为： 应用程序\用户

应用程序\约会

public function user() 
{ 
     return $this->belongsTo('App\Models\User'); 
}

请帮忙

这是我的组件代码：

如果您通过嵌套组件绑定用户，并且如果关系是一个多用户和约会（理解用户有一个或多个约会），我认为应该是这样的：

@livewire('user-appointments', ['user' => $user], key($user->id)) // I assume that this component is for the                                  // appointments of this user

你能分享完整的组件代码和刀片代码吗？？？如何检索$user并绑定到blade？我共享了我的组件，但未将此属性（$this->related\u id-$this->user\u id）声明作为公共声明。当您调用load method assign values to this，$this->user属性没有看到任何初始化，但在您作为参数（在错误图像中）传递给createShowModal方法的刀片中，语句'related_id'=>$this->user->id与您没有看到的$this->user初始化相关。您能用现在更新的代码修复或更新错误图像吗？我不擅长livewire，但我使用相同的用户表，并将其声明为public$user。你的意思是我删除了public$user；并通过公共用户_id进行更改；与公众有关的身份证；这是在其他刀片中调用它的线路：

@livewire('user-appointments', ['user' => $user], key($user->id)) // I assume that this component is for the                                  // appointments of this user
