I'm following a tour for Laravel 5.3 and I'm in the implementation of a shopping bug but I have an error in the whole project for having called a variable in the following file:
resourses / layouts / app.blade
where I place:
<li>
Mi carrito
<span class="circle-shopping-cart">
{{$shopping_cart->productsSize()}}
</span>
</li>I have created the ShoppingCArt model:
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class ShoppingCart extends Model
{
protected $fillable = ["status"];
public function productsSize(){
return 20;
}
public static function findOrCreateBySessionID($shopping_cart_id){
if($shopping_cart_id)
return ShoppingCart::findBySession($shopping_cart_id);
else
return ShoppingCart::createWithoutSession();
}
public static function findBySession($shopping_cart_id){
return ShoppingCart::find($shopping_cart_id);
}
public static function createWithoutSession(){
return ShoppingCart::created([
"status" => "incompleted"
]);
}
}and this is your controller:
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Http\Requests;
use App\ShoppingCart;
class MainController extends Controller
{
public function home()
{
$shopping_cart = ShoppingCart::findOrCreateBySessionID(null);
return view('main.home',["shopping_cart" => $shopping_cart]);
}
}But it gives me an error that tells me that the error is here:
<li>
Mi carrito
<span class="circle-shopping-cart">
{{$shopping_cart->productsSize()}}
</span>
</li>I DO NOT SEE THE ERROR
