Ruby ruby 3.2 代码脚手架生成的 sql 默认主键为空导致报错有人知道怎么设置主键为非空么
== CreatePosts: migrating ==================================================== -- create_table(:posts) rake aborted! StandardError: An error has occurred, all later migrations canceled:

ruby 是 2.1.6 rails 是 3.2.22.2 生成 model 语句为 demo 实例：rails generate scaffold Post name:string title:string content:text

直接加了个全局补丁。看起来是老版本对 mysql 的适配有问题
