Question

在我的使用laravel blade的视图中使用以下循环

 @foreach ($items as $item)                               
       <li class="dd-item" data-id="13">
           <div class="dd-handle">{{ $item->title}}
           </div>
       </li>
 @endforeach

我得到了

Invalid argument supplied for foreach() (View:...)

如果我使用dd（$ items），我会看到洞对象

object(Illuminate\Database\Eloquent\Collection)[473]
  protected 'items' => 
    array (size=1)
      0 => 
        object(Td\Reports\Contents\Contents)[471]

控制器方法

public function getAll($child = null) {

    $view = Request::segment(2);

    $contents = array('menus', 'categories');
    if (in_array($view, $contents)) {
        return View::make('reports::admin.' . $view . '.index')
                        ->with('items',$this->getMenus());
    } else {
        return View::make('reports::admin.contents.index');
    }
}

/**
 * Get Menus
 * @return Posts
 */
public function getMenus() {
    //dd($this->model->where('type', 'menu_item')->get());
    return $this->model->where('type', 'menu_item')->get();
}

Answer 1

尝试：

return  Response::make(View::make('reports::admin.' . $view . '.index', array('items'=>$this->getMenus())));

代替。
