尝试从数据透视表Laravel获取列数据

嗨，我正在尝试从我的数据透视表中输出特定的列。为了向您展示我尝试过的内容，我将首先向您展示我的模型（我的数据透视表是ordertasks和tagtasks）：

任务表：

class Task extends \Eloquent {

    // Add your validation rules here
    public static $rules = [
        // 'title' => 'required'
    ];

    // Don't forget to fill this array
    protected $fillable = ['task_name','task_description','hour','difficulty'];

    public function ordertask()
    {   
        //oneToMany
        return $this->hasMany('Ordertask', 'id_task', 'id');
    }

    public function tagtask()
    {   
        //oneToMany
        return $this->hasMany('Tagtask', 'id_task', 'id');
    }


}

Tagtask表：

<?php

class Tagtask extends \Eloquent {
    protected $fillable = ['id_tag','id_task'];

    public function task()
    {   
        //manyToOne
        return $this->belongsTo('Task', 'id_task', 'id');
        //return $this->belongsTo('Task');
    }
    public function tag()
    {   
        //manyToOne
        return $this->belongsTo('Tag', 'id_tag', 'id');

    }
}

订单任务表：

<?php

class Ordertask extends \Eloquent {

    // Add your validation rules here
    public static $rules = [
        // 'title' => 'required'
    ];

    // Don't forget to fill this array
    protected $fillable = ['id_order','id_task', 'hour', 'hourprice','id_user', 'createdBy'];

    public function user()
    {   
        //manyToOne
        return $this->belongsTo('User', 'id_user', 'id');
        //return $this->belongsTo('User');
    }

    public function task()
    {   
        //manyToOne
        return $this->belongsTo('Task', 'id_task', 'id');
        //return $this->belongsTo('Task');
    }
}

这是我的TaskController.php，其中包含以下代码：

public function index()
    {
        $Tasks=Task::with('tagtask','ordertask')->get(); 
        return View::make('user.tasks.index', compact('Tasks'));
    }

现在好了，我想用以下代码在浏览器上显示$ Task-> ordertask ['id_user']的部分：

@if (count($Tasks)) 
<ul>
   @foreach($Tasks as $Task)
   <div class="row">
      <div class="col-md-3">
         <li>
            {{--as a third parameter we need to pass in the id of task, because it needs to be fed to
            our actual user.task.edit route. --}}
            {{link_to_route('user.tasks.edit', $Task['task_name'], array($Task->id))}}
         </li>
      </div>
      <div class="col-md-3">
         <li>   
            {{$Task->ordertask['id_user']}}
         </li>
      </div>
      <div class="col-md-3">
         <li>   
            {{$Task['task_hour']}}
         </li>
      </div>
      <div class="col-md-3">
         <li>
            {{Form::open(array('route'=>array('user.tasks.destroy',$Task->id),
            'method'=>'delete','class'=>'destroy'))}}
            {{Form::submit('Delete')}}
            {{Form::close()}}
         </li>
      </div>
   </div>
   @endforeach
</ul>
@endif

不幸的是，这不起作用，因为我收到以下错误：

Undefined index: id_user

代替：

{{$Task->ordertask['id_user']}}

我也尝试过这样做只是为了看看它给了我什么输出：

{{$Task->ordertask}}

这给了我以下输出：

[{"id":5,"id_order":2,"id_task":1,"hour":63,"hourprice":15,"id_user":5,"createdBy":4,"created_at":"2014-10-13 10:21:33","updated_at":"2014-10-13 10:21:33"}]

所以很高兴我想从ordertask表中输出id_user。很高兴我在等待您的答复。无论如何，谢谢您的回复。
