loop through json array and retrieve one attribute, gives errors also - ruby

Question

i am new to programming in ruby, and i am trying to get the value of json['earning_rate_hr'] but i get an error, in '[]': no implicit conversion of String into Integer (TypeError)
i know and i understand the error, however this is not my main question here is my file :
checkingchecker.rb :
#require_relative '../lib/hackex/net/typhoeus'
require_relative '../lib/hackex'
require 'rubygems'
require 'json'
file = 'accounts1.txt'
f = File.open file, 'r'
puts "MADE BY THE PEOPLE, FOR THE PEOPLE #madebylorax"
puts ""
puts "--------------------------------------------------------"
puts ""
while line = f.gets
line = line.chomp.split(';')
email, password = line
puts "logging in as " + email
HackEx.LoginDo(email, password) do |http, auth_token, user|
puts "getting info..."
user = HackEx::Request.Do(http, HackEx::Request.UserInfo(auth_token))['user']
puts "receieved user info!"
bank = HackEx::Request.Do(http, HackEx::Request.UserBank(auth_token))['user_bank']
puts "recieved bank info!"
json = HackEx::Request.Do(http, HackEx::Request.UserSpam(auth_token))['spam']
puts "recieved spam info!"
puts json['earning_rate_hr'] #error line, the error is because this is an array, and it cant be turned into integer, i was wondering if there is a way to use puts on it without trying to make it an integer
userchecking = bank["checking"]
checking = userchecking.scan(/.{1,3}/).join(',')
puts email + " has in Checking: BTC #{checking}"
puts ""
puts "--------------------------------------------------------"
puts ""
end
end
i tried to do puts json, it puts items like this one :
{"id"=>"9867351", "user_id"=>"289108", "victim_user_id"=>"1512021",
"victim_ip"=
"86.60.226.175", "spam_level"=>"50", "earning_rate_hr"=>"24300", "total_earning s"=>"13267800", "started_at"=>"2015-11-01 07:46:59",
"last_collected_at"=>"2015- 11-24 01:46:59"}
what i want to do is select the earning_rate_hr for each one of them and add them together, however i do not have a clue on how to do that, since the error is not fixed and i cant get the value of it
ps : i tried turning it into a Hash, and i also tried using .first, but .first only shows the firs one, i want to show all of them, thank you

Answer 1

I know you from line messenger, I haven't used ruby codes in a long time and this one keeps giving me cloudflare errors, I'm not sure if its because of server downtime/maintainance or whatever but yeah anyway heres your script, enjoy farming ;) -LineOne
PS, I changed a few strings to make it look a lil cleaner so you can see the spam income easier, and added the sleep (1) because sleeping for one second before reconnecting helps to prevent cloudflare errors
also you don't need to require json or rubygems in your hackex scripts because its required in the library so its all covered pre-user-input/script
require_relative 'libv5/lib/hackex'
while 1<2
begin
print'Filename: '
fn=gets.chomp
file = fn+'.txt'
f = File.open file, 'r'
puts "MADE BY THE PEOPLE, FOR THE PEOPLE #madebylorax" #helped by lineone
puts ""
puts "--------------------------------------------------------"
puts ""
while line = f.gets
line = line.chomp.split(';')
email, password = line
HackEx.LoginDo(email, password) do |http, auth_token, user|
puts "Retrieving Info..."
puts''
user = HackEx::Request.Do(http, HackEx::Request.UserInfo(auth_token))['user']
bank = HackEx::Request.Do(http, HackEx::Request.UserBank(auth_token))['user_bank']
json = HackEx::Request.Do(http, HackEx::Request.UserSpam(auth_token))['spam']
cash_count=0
tot_count=0
json.each do |j|
earn_rate = j['earning_rate_hr']
total= j['total_earnings']
cash_count+=earn_rate.to_i
tot_count+=total.to_i
end
print "#{email}: current earnings: #{cash_count} per hour, Total earnings #{tot_count},"
userchecking = bank["checking"]
checking = userchecking.scan(/.{1,3}/).join(',')
puts " #{checking} BTC in Checking"
puts ""
puts "--------------------------------------------------------"
puts ""
sleep 1
end
end
rescue
puts"#{$!}"
end
end

Answer 2

Thats fine you can also calculate the total income of your farms by adding new variables at the top example a=0 then adding the number at the end a+=tot_count

Answer 3

This should help:
earning_rates = json.map{|e| e["earning_rate_hr"]}
puts "Earning rates per hour: #{earning_rates.join(" ")}"
puts "Sum of earning rates: #{earning_rates.map{|e| e.to_i}.inject{|sum, x| sum + x}}"
