在Laravel 5.2中查看数据表单id列

Question

我在数据库教室和状态中有两个表。课堂字段为id，subject，class_code，user_id。我为每个班级建立了一个链接。现在我想在每个班级的班级视图页面中显示数据。如果我的班级链接class?class_id=47，则其必须仅显示class?class_id=47数据，如果class?class_id=55必须显示class?class_id=55数据，但在我的class?class_id=55班级中则显示班级？class_id = 47类数据。

我的控制器：

public function getclass(Request $request)
{
    $id = $request->get('class_id'); if(Input::has('status-text'))
    {
        $text=e(Input::get('status-text'));
        $rules = [
        'status_text'=>'required|string',
        ];
        $validator = Validator::make($request->all(), $rules);
        if(Input::hasFile('status_image_upload'))
        {
            $rules['status_image_upload'] = 'image';
            $validator = Validator::make($request->all(), $rules);
            if($validator->fails())
            {
                $image = $request->file('status_image_upload');
                $imageName = str_random(8).'_'.$image->getClientOriginalName();
                $image->move('status_images', $imageName);
                $userStatus = new Status();
                $userStatus -> class_id = $id;
                $userStatus -> status_text = $text;
                $userStatus -> image_url = $imageName;
                $userStatus -> type = 1;
                $userStatus -> users_id = Auth::user()->id;
                $userStatus -> save();
                Flash::success('Your status has been posted');
                return redirect(route('class',['class_id'=>$id]));
            }
        }
        else if ($validator->fails())
        {
            $userStatus = new Status();
            $userStatus -> class_id = $id;
            $userStatus -> status_text = $text;
            $userStatus -> video_url = $request['video_url'];
            $userStatus -> type = 2;
            $userStatus -> users_id = Auth::user()->id;
            $userStatus -> save();
            Flash::success('Your status has been posted');
            return redirect(route('class',['class_id'=>$id]));
        }
}return view('class',[
'posts'=>status::orderBy('id','DESC')->get()
])->with('class_id',$request->get('class_id'))
->with('classroom',classroomModel::find($id)->first());}

我的观点

<li>Subject-->{{$classroom->subject_name}}</li>
<li>Section-->{{$classroom->section}}</li>

应该怎么做？
