Question

我的应用程序上有一个工作车/结帐功能，在localhost上工作得非常好，但是当我部署到Heroku项目时，当＆＃34;添加到购物车＆＃34;时，不会将其添加到购物车中。单击按钮。

Heroku日志显示错误：

谁能看到发生了什么？我迷失了，因为我无法看到任何适用于localhost而非Heroku的内容。

您的错误已经归结为，您尝试将记录插入orders，其值order_status_id违反约束条件。这可能是因为您使用一些OrderStatus对象在本地播种了数据库，并将其ID硬编码到您的代码中。但是，这些记录在您的生产数据库中不存在。您应该更新代码以根据请求从数据库中提取订单状态选项，然后在生产数据库中创建相关的状态记录。
