我正在尝试使用Puma Web服务器部署Rails应用程序.当尝试使用配置文件启动Puma服务器时,bundle exec puma -C config/puma.rb我收到一个错误,表明该地址已被使用.
有人知道如何解决这个问题吗？

用户应该能够填写高级搜索表单的选项,然后单击"保存此搜索"链接,该链接将存储他们的选项.有了这个,每个用户都将拥有自定义的默认搜索选项,因此每次访问时都不需要重新输入详细信息.
我认为这对未来很多人都有帮助.

我已阅读txdavidtx建议.他建议将所有用户标记为在结算周期结束时取消.那种方法不适合我想要完成的任务.
我订阅设置为autorenew.我需要cancel创建一个仅current_user在结算周期结束时标记为已取消的操作.
例如:
用户A在9月27日报名参加月度订阅.用户A决定在12月15日取消订阅.用户A的订阅还剩12天.用户A单击该cancel链接.用户A在其PayPal或Stripe帐户中已取消自动更新和订阅.在我的数据库中,他们的cancelled属性值在12天(12月27日)结束之前不会改变.
