You definitely want to hide IDs from your app.

It's a very basic security consideration.

There are many Ruby gems that let you hide ids, but neither gem is plug & play:

Some gems require adding a slug attribute to each model.

Some gems require updating your finder methods.

I don't want to decorate my internal resource slugs.

I don't want to care about UUIDs or ULIDs.

I just want to say hide my IDs and it just works.

The best plug & play solution that I found is in Bullettrain source code: http://github.com/bullet-train-co/bullet_train-core

Here's how you can hide ids in your Rails app
