Cannot Convert String to Integer error in Ruby

In my ruby code I am running into a "cannot convert string to Integer" error. The code is:

require 'rubygems'
require 'oauth'
require 'json'

# Now you will fetch /1.1/statuses/user_timeline.json,
# returns a list of public Tweets from the specified
# account.


  baseurl = "https://api.twitter.com"
path    = "/1.1/statuses/user_timeline.json"
query   = URI.encode_www_form(
    "q" => "Obama"
    "count" => 1
    )
address = URI("#{baseurl}#{path}?#{query}")
request = Net::HTTP::Get.new address.request_uri

# Print data about a list of Tweets
def print_timeline(tweets)
  tweets.each do |tweet|
  require 'date'
   d = DateTime.parse(tweet['created_at'])
    puts " #{tweet['text'].delete ","} , #{d.strftime('%d.%m.%y')} , #{tweet['user']   ['name']}, #{tweet['id']}"
  end
end

# Set up HTTP.
http             = Net::HTTP.new address.host, address.port
http.use_ssl     = true
http.verify_mode = OpenSSL::SSL::VERIFY_PEER

# If you entered your credentials in the first
# exercise, no need to enter them again here. The
# ||= operator will only assign these values if
# they are not already set.
consumer_key = OAuth::Consumer.new(
    "")
access_token = OAuth::Token.new(
    "")

# Issue the request.
request.oauth! http, consumer_key, access_token
http.start
response = http.request request

# Parse and print the Tweet if the response code was 200
tweets = nil

puts "Text,Date,Name,id"
if response.code == '200' then
  tweets = JSON.parse(response.body)
  print_tweets(tweets)
end
nil

After debugging, I believe the error is coming from lines 19 or 20 (d = and puts statement). I am not sure what String is attempting to be converted to an integer.

It looks like you're trying to access tweet['created_at'] whereas tweet is not a Hash structure. You should try to inspect the structure of tweet ( and maybe of tweets as well ).

You can look at the class with tweet.class or directly inspect it : tweet.inspect

I'd guess tweet is an array, and its elements should therefore be called using an integer, not a string
