＃{path}和“＃{RAILS_ROOT}”之间的区别是什么？

Question

I know that RAILS_ROOT is the old way of getting Rails.root and that it returns a string while Rails.root returns a Pathname object. I have had issues using RAILS_ROOT before loading the environment. As a quick solution I use #{path} which works and returns also the root path as a tring. I have also noticed that while RAILS_ROOT and Rails.root work as expected on console, #{path} does not.

So what is this #{path} and where does it come from?

To my knowledge there is not a "path" variable set by default. Do a search on your code base for "path" and see where it is being set.
