Fixer Currency

This gem extends Money::Bank::VariableExchange with Money::Bank::FixerCurrency and gives you access to the current fixer.io exchange rates.

This gem was forked from the Money::Bank::GoogleCurrency gem.

Usage

require 'money'
require 'money/bank/fixer_currency'

# (optional)
# set the seconds after than the current rates are automatically expired
# by default, they never expire
Money::Bank::FixerCurrency.ttl_in_seconds = 86400

# set default bank to instance of FixerCurrency with access key parameter
# being your access_key from fixer.io
Money.default_bank = Money::Bank::FixerCurrency.new('your_access_key')

# create a new money object, and use the standard #exchange_to method
money = Money.new(1_00, "USD") # amount is in cents
money.exchange_to(:EUR)

# or install and use the 'monetize' gem
require 'monetize'
money = 1.to_money(:USD)
money.exchange_to(:EUR)

An UnknownRate will be thrown if #exchange_to is called with a Currency that Money knows, but fixer.io does not.

An UnknownCurrency will be thrown if #exchange_to is called with a Currency that Money does not know.

A FixerCurrencyFetchError will be thrown if there is an unknown issue with parsing the response including rates from fixer.io's API.

Caveats

This gem uses fixer.io under the hood.
