Dev with 5 of experience switched to Rails, what should I be careful about?

[vampiregrey]

Coming to Rails with ~5 years of professional experience, but new to the Rails way of doing things.

It feels productive and opinionated in a good way.

So far I’m enjoying the conventions and speed, but I’m aware every framework has sharp edges you only discover later.

What are the mistakes that experienced developers still fall into when adopting Rails?
