I am using the following method in a service (sms notification via. twilio), and I would like to add number_to_currency to the message so the amount is formatted nicely. I have tried a few approaches, but I cannot seem to get it to work. Any thoughts?

My method looks like this:

def message(details)
  "A transaction of #{details[:amount]} was processed."
end
twilio ruby ruby-on-rails

Probably you can use NumberHelper#number_to_currency

include ActionView::Helpers::NumberHelper

def message(details)
  "A transaction of #{number_to_currency(details[:amount])} was processed."
end

It will use current locale, but you can specify it and also format output with these options

:locale - Sets the locale to be used for formatting (defaults to current locale).

:precision - Sets the level of precision (defaults to 2).

:unit - Sets the denomination of the currency (defaults to “$”).

:separator - Sets the separator between the units (defaults to “.”).

:delimiter - Sets the thousands delimiter (defaults to “,”).

:format - Sets the format for non-negative numbers (defaults to “%u%n”). Fields are %u for the currency, and %n for the number.

:negative_format - Sets the format for negative numbers (defaults to prepending a hyphen to the formatted number given by :format). Accepts the same fields than :format, except %n is here the absolute value of the number.

:raise - If true, raises InvalidNumberError when the argument is invalid.

:strip_insignificant_zeros - If true removes insignificant zeros after the decimal separator (defaults to false).
