Rails 7 adds Pathname#existence

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

Before

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?
Copy

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
Copy
