Configs: database.yml => database.rb?

Question

Ruby on Rails

I completely rewrote database.yml in ruby ​​format on one of the projects and everything worked fine.
I create a new project, I try to write in the same style, but when I start the server I get an error that the database.yml file was not found.
Of course, he doesn't.
But what is the reason that database.rb is normally picked up on one project, but not on the other?
And how would you fix it?

What are the rail and activerecord versions on the projects?
