This gem extends Money::Bank::VariableExchange with Money::Bank::OandaCurrency and gives you access to the current Oanda exchange rates.
This gem was forked from the Money::Bank::GoogleCurrency gem.
If the money gem is not already installed:
gem install money
Install the Oanda_currency gem:
gem install Oanda_currency
require 'money'
require 'money/bank/oanda_currency'
# (optional)
# set the seconds after than the current rates are automatically expired
# by default, they never expire
Money::Bank::OandaCurrency.ttl_in_seconds = 86400
# set default bank to instance of OandaCurrency with access key parameter
# being your access_key from Oanda
Money.default_bank =
Money::Bank::OandaCurrency.new(
rate_store,
'your_access_key',
currencies_supported
)
# 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 Oanda does not.
An UnknownCurrency will be thrown if #exchange_to is called with a
Currency that Money does not know.
A OandaCurrencyFetchError will be thrown if there is an unknown issue with
parsing the response including rates from Oanda's API.
This gem uses Oanda under the hood.
