Laravel查询异常错误

我正在尝试运行以下"Results（）"查询，并在我的视图中得到以下与foreach循环相关的错误：

public function index()
    {
        //show view of homepage
        return View::make('index');
    }
    public function results()
    {   
        $query = DB::table('Unions'); // Get the table before applying the where clauses
        if (Request::get('Affilation')) {
            $Affilation = Input::get('Affilation');
            if ($Affilation != null) {
                $query = $query->where('Affilation', $Affilation);
            }
        }
        if (Request::get('Office_State')) {
            $Office_State = Input::get('Office_State');
            if ($Office_State != null) {
                $query = $query->where('Office_State', $Office_State);
            }
        }
        if (Request::has('Local_Name')) {
            $Local_Name = Input::get('Local_Name');
            if ($Local_Name != null) {
                $query = $query->where('Local_Name', $Local_Name);
            }
        }
        $results = $query->get(); // Calling get() will execute the query, so it must be last to be called
        //show results from union search
        return View::make('results')->with('union', $results);
     } 

    public function profile($Local_Name)
    {
            $union = Union::whereLocal_name($Local_Name)->first();
        //show individual union profile
        return View::make('profile', ['union' => $union]);
        } 

这是一个大卡盘的错误：

这是参考的视线44：

<?php if($unions->count()): ?>
        <?php foreach($unions as $union): ?>
