@rate - shows how many Rubles should be given for 1 Euro, or Japanese Yen, or Turkish Lira, etc. For example, you should give 62,93 Russian Rubles for 1 Euro; or 0.46 Rubles (or 46 kopecks) for 1 Japanese Yen.
CbrCurrency.configure do |config|
config.cbr_uri = "www.example.com"
config.logger = mylogger
config.proxy_host = 'proxy'
config.proxy_port = 8080
end
It is expected, that cbr_uri gives an XML of the following format:
<ValCurs Date="24.07.2015" name="Foreign Currency Market">
<Valute ID="R01010">
<NumCode>036</NumCode>
<CharCode>AUD</CharCode>
<Nominal>1</Nominal>
<Name>Австралийский доллар</Name>
<Value>42,4964</Value>
</Valute>
</ValCurs>
By default cbr_uri = "http://www.cbr.ru/scripts/XML_daily.asp".
By default logger is able to use Rails logger if you integrate this gem to a Rails app, otherwise Logging to STDOUT will be used.
