你采取了哪些措施来消除Rails开发中的错误？

A single Rails command can make lots of changes in an app - creating files and migrations, adding routes, etc. Undoing the damage of a mistake could be tricky for a beginner.

单个Rails命令可以在应用程序中进行大量更改 - 创建文件和迁移,添加路由等。对于初学者来说,撤消错误的损坏可能会非常棘手。

For example, say you generate some scaffolding, run the migration, and then realize your scaffolding command should have been singular (ruby script/generate scaffold cake type:string) instead of plural (ruby script/generate scaffold cakes type:string).

例如,假设您生成一些脚手架,运行迁移,然后实现您的脚手架命令应该是单数(ruby脚本/生成脚手架蛋糕类型:字符串)而不是复数(ruby脚本/生成脚手架蛋糕类型:字符串)。

If you destroy the scaffolding before rolling back the database migration, you've created another problem.

如果在回滚数据库迁移之前销毁脚手架,则会产生另一个问题。

So: what steps do you take to undo mistakes in Rails development?
