骨干Js Delete无法正常工作

Question

我正在使用CodeIgniter rest应用程序和ribs.js开发一个应用程序。

我正在尝试从数据库中删除一条记录。骨干模型返回成功回调，数据库数据未删除。

    $("#deleteItem").click(function (event) {
        event.preventDefault();
        console.log("toing" + deleteItemID);

        var deleteUserModel = Backbone.Model.extend({
            urlRoot: "http://localhost/WishListApplication/index.php/listItem/removeItem",
            defaults: {
                userId: '',
                itemURL: ''

            }
        });

        var removeItem = new deleteUserModel({userId: <?php echo $this->session->userdata('userId'); ?>,
            itemURL: deleteItemID});

        removeItem.destroy(
                {
                    success: function (model, response, options) {
                        console.log(response);
                        $('#delete-item').modal('hide');

                        console.log("The model has deleted the server");
                    },
                    error: function (model, xhr, options) {
                        console.log("Something went wrong while deleting the model");
                    }
                });



    });

这是我的控制器类

public function removeItem_delete() {
    $userId = $this->delete('userId');

    $itemURL = $this->delete('itemURL');


    $deletedItem = $this->itemModel->deleteItem($userId, $itemURL);

    //checks whether item has successfully deleted from the database
    if ($deletedItem !== false) {
        //display sucess message
        $data['messages'] = 'Item has been deleted successfully';
        $data['success'] = true;
    } else {
        $data['messages'] = 'Something went wrong - Please try to delete Item again';
        $data['success'] = false;
    }
    echo json_encode($data);
}

我是骨干新手。请有人帮我解决这个问题。

预先感谢
