我使用的是从here
获得的Laravel购物车包我已按照说明安装软件包。
这是"C:\Program Files\Java\jdk1.8.0_92\bin\java" -cp folder1.classfile folder2\parameter.txt > Logs\log.out 2>&1 & echo $! > Files/pid.txt
模型类：
Cart.php namespace App;
use Amsgames\LaravelShop\Models\ShopCartModel;
class Cart extends ShopCartModel
{
}
ShopCartModel最后是use Amsgames\LaravelShop\Contracts\ShopCartInterface;
use Amsgames\LaravelShop\Traits\ShopCartTrait;
use Amsgames\LaravelShop\Traits\ShopCalculationsTrait;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Support\Facades\Config;
class ShopCartModel extends Model implements ShopCartInterface
{
use ShopCartTrait, ShopCalculationsTrait;
/**
* The database table used by the model.
*
* @var string
*/
protected $table;
/**
* Fillable attributes for mass assignment.
*
* @var array
*/
protected $fillable = ['user_id','user_count', 'user_price'];
/**
* Creates a new instance of the model.
*
* @param array $attributes
*/
public function __construct(array $attributes = [])
{
parent::__construct($attributes);
$this->table = Config::get('shop.cart_table');
}
}
ShopCartInterface我尝试做的是在以下代码中将商品添加到购物车

public function remove($item, $quantity = 0);

public function hasItem($sku, $requireAll = false);

public function scopeCurrent($query);

public function getTotalPriceAttribute();

public function getDisplayTotalAttribute();

public function placeOrder($statusCode = null);
/**

*/
public function clear();
}
我收到了这个错误
$items = DB::table('apps as a')
->leftJoin('odoo_modules as b', 'a.i_odoo', '=', 'b.id')
->whereIn('a.id', Input::get('items'))
->select('a.id as i_apps', 'b.name as sku', 'a.price')
->get();
$cart = \App\Cart::current();
foreach($items as $item){
$cart->add(['sku' => $item->sku, 'i_apps' => $item->i_apps, 'price' => $item->price]);
}
我是否必须在模型BadMethodCallException in Builder.php line 2345:
Call to undefined method Illuminate\Database\Query\Builder::add()
中实施add方法？如果没有导致错误的原因是什么？
