Handling international currency input in Ruby on Rails

Question

I have an application that handles currency inputs. However, if you\'re in the US, you might enter a number as 12,345.67; in France, it might be 12.345,67

Answer 1

Using the translations for numbers in the built-in I18n should allow you to enter your prices in one format (1234.56) and then using I18n bringing them back out with number_to_currency to have them automatically printed out in the correct locale.

Of course you'll have to set I18n.locale using a before_filter, check out the I18n guide, section 2.3.
