This blog is part of our  Rails 7 series.

Rails 7 introduces Pathname#existence method, which returns the receiver if the given file path exists otherwise returns nil.


We need to first check whether the given file path exist or not to perform any other operations on it.

1=> file_path = "config/schedule.yml"
2=> Pathname.new(file_path).read if Pathname.new(file_path).exist?

Rails 7 onwards

The Pathname#existence method acts like Object#presence for file existence.

1=> file_path = "config/schedule.yml"
2=> Pathname.new(file_path).existence&.read
