Changing currency

I would like to change the currency in my app for each site.

So i currently have number_to_currency(aNumber, :locale => :gb) which works well. I have a number of sites which use different currencies and have their country set in @sites.currency - this passes in gb, eu, us, vi for example.

How would i go about changing the :locale => :fr to :locale => :gb as currently i can only get it passing in as a string, which is not obviously valid.

@sites.currency.to_sym should work. 👍

@sites.currency.downcase.to_sym worked a treat buddy, thanks :)
