中间件用于控制器中的操作，Laravel 5.1

Question

我有一个具有索引方法的控制器，但也有多个级别的用户可以访问此方法，但是单个管理员可以查看数据库的所有记录如何添加中间件以选择相应的操作给用户？我有下一个代码

<?php

namespace SET\Http\Controllers;

use Illuminate\Http\Request;
use Illuminate\Support\Facades\Session;
use Illuminate\Support\Facades\Redirect;
use SET\Http\Requests;
use SET\Http\Requests\LabRequest;
use SET\Http\Controllers\Controller;
use Illuminate\Routing\Route;
use SET\Lab;
use Validator;
use Auth;
use DB;

class LaboratorioController extends Controller
{
public function __construct(){
    $this->beforeFilter('@find', ['only' => ['show','edit','update','destroy']]);
}

public function find(Route $route){
    $this->laboratorio = Lab::findOrFail($route->getParameter('laboratorio'));
}
/**
 * Display a listing of the resource.
 *
 * @return Response
 */

public function index()
{
    $labs = Lab::all();
    return view('comp.lab.index',['labs' => $labs]);
}

/**
 * Show the form for creating a new resource.
 *
 * @return Response
 */
public function create()
{
    return view('comp.lab.create');
}

/**
 * Store a newly created resource in storage.
 *
 * @return Response
 */
public function store(LabRequest $request)
{       Lab::create($request->all());
        Session::flash('message','Laboratorio creado correctamente');
        return Redirect::to('/laboratorio');
}

/**
 * Display the specified resource.
 *
 * @param  int  $id
 * @return Response
 */
public function show()
{
     $teams = $this->laboratorio;
    return view('comp.lab.show',['lab'=>$this->laboratorio]);
}

/**
 * Show the form for editing the specified resource.
 *
 * @param  int  $id
 * @return Response
 */
public function edit()
{
    return view('comp.lab.edit',['lab'=>$this->laboratorio]);
}

/**
 * Update the specified resource in storage.
 *
 * @param  int  $id
 * @return Response
 */
public function update(LabRequest $request)
{
    $this->laboratorio->update($request->all());
    Session::flash('message','El laboratorio se actualizo correctamente');
    return Redirect::to('/laboratorio');
}

/**
 * Remove the specified resource from storage.
 *
 * @param  int  $id
 * @return Response
 */
public function destroy()
{
    $this->laboratorio->delete();
    Session::flash('message','El laboratorio fue eliminado correctamente');
    return Redirect::to('/laboratorio');
}

谢谢:D

Answer 1

这是一个总体思路：

$user_group = $user::get_user_group($user_id)
if($user_group->group_id === 'something'){
    \\method to return data for group 'something'
}

按组获取数据

$user_data = $user::get_data_by_group_id($group_id)
