Where to put a file in io.foreach?

Rails
1

Hi there,

I want a piece of code in my controller to grab a text file with a list
of words in it, but I don’t know where to put that text file
(words.list).

Here’s the relevant code:

def puzzle_generator
# Load all 3-17 letter words into a hash for fast lookup
words = Hash.new
IO.foreach(“words.list”) do |line|

Where should I put words.list? I tried writing out a path to it, but I
keep getting “No such file or directory - words.list”.

Any ideas? This is the first time I’ve tried this!

words.list should be in the same directory as the .rb that’s calling
it. If that doesn’t work and using the absolute path doesn’t work try
a relative path like …/…/words.list if it’s in your rails_root. In
addition the following code might change things or not, I doubt it
will make it work but it’s a little prettier.

Try the following code:
File.open(“words.list”).each do |line|

Do something with the var line

end

or a slightly different approach

words = File.readlines(“words.list”)

I’m not sure why but IO and foreach seem to be pretty rarely used. I
think they’ve gone out of style. Maybe just because File is easier to
get the gist of when dealing with Files and IO when doing io streams
like tcp/ip.

Hope that helps. If you don’t already have it in your bookmarks try to
find _why’s Pickaxe on google; it’s an old copy of the Ruby manual
with links to the sections. Got me through a lot of pain :slight_smile:

Sincerely,
