laravel 编辑后跳转回分页

进入edit页面时将分页地址保存在session中，更新后跳转该地址

    public function edit(Food $food)
   {
        session()->put('url.intended', url()->previous());
        return view('food.edit', compact('food'));
   }

    public function update(Food $food)
    {
        $food->update($this->checkInput());
//        session()->flash('notice', "updated successfully");
        return redirect()->intended();
    }
