Opencart：エラー番号：1062キー 'PRIMARY'の重複エントリ '1'

Question

アイテムID、アイテム名、リンク、イメージ、並べ替え順序を持つopencartのカルーセル拡張を開発しています。カルーセルには問題がありましたが、保存するとアイテムIDが変更されるため、IDを取得するためにコードを修正する必要がありましたが、今は1062エラーが発生します。モデル/ carousel.php editCarousel機能

public function editCrousal($crousal_image) { 

    $crousal_id = $this->db->getLastId(); 

    $this->db->query("DELETE FROM " . DB_PREFIX . "mobiapp_crousal WHERE crousal_id = '" . (int)$crousal_id . "'"); 

    if (isset($crousal_image['crousal_image'])) { 
     foreach ($crousal_image['crousal_image'] as $crousal_image) { 

      $this->db->query("INSERT INTO " . DB_PREFIX . "mobiapp_crousal SET crousal_id = '" . (int)$crousal_id . "', name = '" . $this->db->escape($crousal_image['name']) . "', link = '" . $this->db->escape($crousal_image['link']) . "', image = '" . $this->db->escape($crousal_image['image']) . "', sort_order = '" . (int)$crousal_image['sort_order'] . "'"); 

      $crousal_id = $this->db->getLastId(); 

     } 
    } 
} 

私はこのエラーを取得し、どのように解決するのよ、なぜ何かアドバイスを共有

Notice: Error: Duplicate entry '1' for key 'PRIMARY' Error No: 1062 INSERT INTO crousal SET crousal_id = '1', name = 'Baby & Toys', link = '/index.php?route=product/product&product_id=7570', image = 'data/carousel/banner2.jpg', sort_order = '0' in /home/user/public_html/system/database/mysql.php on line 49

は、高度でお願いします。

P.S：Opencart 1.5.xを

私は、このモジュールの見直しを行いました。このモジュールのような構造が完全に間違っているようです。あなたが見ることができるように、addCrousalデータベースへの挿入を伴うforeach文。しかし、このインサートでは、carousal_idはテーブル内で増分していないので、一意でないレコードはcarousal_idとなります。この列はPRIMARYにすることはできません。 2つのテーブル「スライド」とリレーション（たくさんある）「イメージ」を使ってモジュールを書き直すことをお勧めします。または、PRIMARYインデックスを削除できますが、操作は成功しますが、それは真の解決策ではありません。
