所以我settings在表中调用了一个 json 列companies（它有一个名为 的 Laravel 模型Company）。该列可能包含也可能不包含名为 的对象business_key。我尝试仅返回包含此对象的公司。我的查询如下所示：

$owners = \Company::where('settings->business_key')->get();

我不知道如何制作这样的作品。我没有找到任何 Laravel 特定于此的东西。感谢您的时间和帮助！

据我了解，AWS Elastic Beanstalk 在软件配置面板中有自己的环境属性，单击齿轮图标。在我的 Laravel 的 .env 文件中，我有一些信息，比如我上传图像的 S3Bucket、我的邮件服务和其他一些信息。这是否意味着我必须将 Laravel 的 .env 文件中的每个键和值对添加到 AWS Elastic Beanstalk 的环境属性中？

我必须得到unit_price数字的总和.我怎样才能做到这一点？

该数组如下所示:

 $scope.items = [
    {
        id: '1',
        name: 'Phone',
        quantity: '1',
        unit_price: '200'
    },
    {
        id: '2',
        name: 'IPhone',
        quantity: '1',
        unit_price: '240'
    }
];
