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.

The "machine root" is `/`, I don't understand the issue. The return is redundant. Single-quoted strings aren't interpolated. — Dave Newton, Oct 06 '13 at 01:59
Also, if the tag's correct, you need to drop ruby 1.8.7 too!! — Jason Whitehorn, Oct 06 '13 at 02:03
If it's a constant, make it one, even if you need a method to return it-then it's easily mocked. Or make it part of your configuration. — Dave Newton, Oct 06 '13 at 02:11

Just replace your method with:

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

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

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

any explanation as to the down-vote would be very constructive – lightswitch05 Oct 06 '13 at 02:17
Thanks, Fixed. I had just copy & pasted that from the question – lightswitch05 Oct 06 '13 at 13:59
Also, it says right in the question that they didn't want the rails root. So, per the OP, this doesn't answer their question. – Jason Whitehorn Oct 06 '13 at 15:02
