Ruby on Rails - get Linux Root?

Question

I am simply trying to get the root path to look up a file on my machine, I am pretty new to RoR. Is there some sort of variable somewhere so I could do something like this:

def path
    return '{#ROOT}/some/path/file.txt'
end

I do not want the Rails root, I want the machine root.

Answer 1

Just replace your method with:

def path
  "/some/path/file.txt"
end

Since root is always /, and return isn't necessary in Ruby.

Answer 2

If you are trying to get the file path, and not the URL path, this will provide the absolute file path of your rails root folder:

Rails.root

From there, you could simple add on the rails path to your file, as your rails directory structure should be static:

def path
    return "{#Rails.root}/some/path/file.txt"
end
