I am trying to populate column_name with items from @enc. Problem is #update_all updates all fields with last item in array?

Last item is "MPq3KSzDzLvTeYh+h00HD+5FAgKoNksykJhzROVZWbIJ36WNoBgkSoicJ5wx\nog0g\n".

I am trying to populate with all items from array not just last. I hope question is clear? I tried #update_attributes, but no success? Help. Thanks

@enc=["hUt7ocoih//kFpgEizBowBAdxqqbGV1jkKVipVJwJnPGoPtTN16ZAJvW9tsi\n3inn\n", "wGNyaoEZ09jSg+/IclWFGAXzwz5lXLxJTUKqCFIiOy3ZXRgdwFUsNf/75R2V\nZm83\n", "MPq3KSzDzLvTeYh+h00HD+5FAgKoNksykJhzROVZWbIJ36WNoBgkSoicJ5wx\nog0g\n"]

@enc.each do |i|
PaymentMethod.update_all(enc_number: i)
end

Could you replace Model and column_name with your actual model and column names? –  Stefan Jul 25 '14 at 9:31
    
@ashwinkumar I am using rails 3.2 so using update_attributes gives error: undefined method –  user3566065 Jul 25 '14 at 9:33
    
@Stefan I dont get what u mean? –  user3566065 Jul 25 '14 at 9:33
    
Your model probably isn't called Model and column_name isn't the actual column's name –  Stefan Jul 25 '14 at 9:34
    
@Stefan I just didnt see how that would help? –  user3566065 Jul 25 '14 at 9:37

  PaymentMethod.all.each_with_index do |payment, n = 0|
   payment.update_column(:enc_number, @enc[n])
   n +=1
  end

I think this code is working but not updating to database? How do I update results to database? –  user3566065 Jul 25 '14 at 9:59
    
What do you mean not updating? and code is working? Is it not updating the fields? Try this "payment.update_attributes(enc_number: @enc[n])" –  ashwin kumar Jul 25 '14 at 10:02

try removing statement "next unless @env.size < n" –  ashwin kumar Jul 25 '14 at 10:10
