Question

问题是我正在使用Rails，并且我的应用程序在Heroku上运行，昨天我添加了宝石carrierwave来将图像上传到该应用程序，但是由于我的应用程序只能在某些设备上使用。它可以在我的PC和iPhone 5上同时在我的iPad上使用，但在iPhone X上则不能。我了解到有些人在image_tag上遇到问题，因此为确保将其删除，我认为这是要注册的devise表格，因此我删除了devise表格。仍然有问题，在某些设备上我的应用无法在其他设备上运行，当我使用Iphone X https://i.stack.imgur.com/Nqb1f.png进行注册时会显示此消息这是我在日志中得到的：

这两行告诉您，数字56996349898大于整数的有效大小范围。编写迁移操作，以将:phone的列数据类型更改为字符串或bigint（从整数）。为了进一步详细说明，由于整数的内存大小为4个字节（32位），因此整数可以为的最大大小为2147483647。从技术上讲，您的电话号码字段所存储的数字大约比整数类型所能容纳的数字大5400万，因此您需要增加该数字。在某些情况下，如果您想进行一些字符串操作或格式化（例如添加连字符或括号），则最好将电话号码表示为文本/字符串。

为什么Rails应用有时会工作，有时却无法工作？
