What is the best way to convert a currency string ‘USD’ to locale
:en-US?
Right now trying to make it flexible to show the money and symbol
correctly
based on the currency string (like ‘USD’ or ‘AUD’) stored against the
user’s record.

I need to be able to do the following based on say ‘GBP’ string:

<%= number_to_currency(1234567890.506, :locale => :en-GB) %>

You could make a helper that would extract this value from the user and
translate the display string. If you set up a hash like {‘USD’ =>
:en-US, ‘GBP’ => :en-BG, …} then there would be one place to look for
the correct symbol.

Hang on do you mean to convert USD 1000 into AUD 1000? Surely you would
need to do a currency conversion because USD 1000 is AUD 1064. This
would
seem to have nothing to do with locales at all.

I just saw a gem on RubyFlow last week that handles currency conversions
using Google as a data source. If that’s what you’re after, forget what
I said and use that.
