Exception Property [Id] Does Not Exist on This Collection Instance

Why am I getting the exception:

Property [id] does not exist on this collection instance.

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Goods;
use App\Categories;

class CategoriesController extends Controller
{
    public function categoryAction($latin_url){
        $category = Categories::where('latin_url', $latin_url)->get();
        var_dump($category->id); die;
        if ($category){
            $goods = Goods::where('category_id', $category->id)->get(); 
            return view('goods', ['goods' => $goods]);
        }
    }
}

$category = Categories::where('latin_url', $latin_url)->get();

This returns you a Collection of results, no only one result. So there is no id attribute. Use:

$category = Categories::where('latin_url', $latin_url)->first();

The above example does not work when there are 0 results, instead of this you can use:

$category = Categories::where('latin_url', $latin_url)->firstOrFail();

what will result in a HTTP 404 error when it does not exist
