How to save a hash into a CSV

Question

I am new in ruby so please forgive the noobishness.

I have a CSV with two columns. One for animal name and one for animal type. I have a hash with all the keys being

Answer 1

Try this:

require 'csv'
h = { 'dog' => 'canine', 'cat' => 'feline', 'donkey' => 'asinine' }
CSV.open("data.csv", "wb") {|csv| h.to_a.each {|elem| csv << elem} }

Will result:

1.9.2-p290:~$ cat data.csv 
dog,canine
cat,feline
donkey,asinine
