我正在尝试创建一个简单的GoBuffalo应用程序，允许用户注册和登录。
我一直跟随着这个例子link
我并遇到一些非常奇怪的行为，在极少数情况下，注册成功完成并创建了一个用户，但是通常，我会收到
mysql create: driver: bad connection
我仅将docker mysql：5.7镜像用于我的数据库。但是也尝试过postgres并收到相同的错误。
我的代码中的验证步骤似乎正确执行了（检查重复的用户名和电子邮件），但是当pop.connection转到insert（create）时，就会发生此错误。
我仍然是Go的新手，但如果有任何帮助可以使我的问题更加简洁，我将不胜感激。另外，有足够声誉的人可以帮助我制作gobuffalo标签。这是在Go中构建Web应用程序的绝佳框架。
