Subject: Need some help with hashes, don't know what fails

Hi all,

I have a hash that contains other hashes, now I'm trying to retreive the
information on those but I can't get the values inside.

Just this code for explain what happens to me:

Im using ruby-1.9.2-p136.

<code>
## just a sample
notifications = Hash.new

notifications['1'] = { what: 'text', who: 'Antonio', when: Time.now}
notifications['2'] = { what: 'text', who: 'Alfonso', when: Time.now}
notifications['3'] = { what: 'text', who: 'Alberto', when: Time.now}

notifications.each do |key, value|
  puts key.inspect              # Getting: '1', '2','3' correct
  puts value.inspect            # Getting: { what: 'text', who:
'Antonio', when: Time.now} and so on. Correct
  puts value.class              # Getting: Hash. Correct
  puts value.has_key?('what')   # Getting false. Incorrect
  puts value.has_key?('when')   # Getting false. Incorrect
  puts value.has_key?('data')   # Getting false. Incorrect


  # I get the values....
  value.each do | k, v |
    puts "#{k}: #{v}"
  end
end
</code>

Thanks in advance.
