Rails Currency Formatting

Question

I'm working on a Rails app and I'm trying to figure out the best way of allowing users to change the currency format of a report. It's not something that would be tied to their country or location since they may have to send the report to people from other countries.

I initially only want support for these 3: USD, GBP, and EUR

Also, there's no need for currency conversion. What's the best way to go about this in Rails?

Answer 1

Check out the number_to_currency helper.

Answer 2

Rather than another drop down, I'd suggest a list of links that have different values with examples and then let the user click the one that matches what they are expecting.

To make things a little more user friendly you could also tie in with a GeoIP service to sort out what country they are from to set the default format.
