Using the Yahoo Finance Gem

I am trying to use the Yahoo Finance Gem, but am not able to get the information I want. When I try to get a quote, it creates a hash, but instead of the individual information (which I am trying to get), it gives a string will all the information in it. Is there a way to receive a single bit of information (such as % change) as a number? I am very new to ruby, so any help would be awesome.

Solution 
  • require 'yahoofinance'
YahooFinance.get_quotes(YahooFinance::StandardQuote, 'yhoo') {|i|
  puts i.change
  puts i.changePoints
  puts i.changePercent
  puts i.time
}

    Prints for me:

    -0.03 - -0.17%
-0.03
-0.17
10:55am

    or

    r = yahooFinance.get_quotes(YahooFinance::StandardQuote, 'yhoo')
puts r[r.keys[0]].dayHigh
puts r["YHOO"].dayHigh

    prints:

    17.43
17.43

    YahooFinance.get_quotes return a hash in which quote symbols are keys, and all data for each quote is a value. See YahooFinance::BaseQuote class to guess why it is possible to use getters like dayHigh() to auto parse data from the hash value.
