Multiple currencies in Rails

Question

I want to be able to support multiple (3 for now) currencies on my website. I am a beginner and have doubts on how to do this . I have searched a bit and I have a list of questions. Following are my requirements.

• I do not want to change the labels/text on my website, but just the price of the products based on selected currency .I have found 2 ways to do it .

  • Using the money gem https://github.com/RubyMoney/money
  • Using I18n https://github.com/svenfuchs/rails-i18n

Please suggest which one is better to go for (for an ecommerce website). Also , are there any good tutorials on how to implement them.

• I want to be able to detect the user's IP and set the currency based on his country. I also want to give the user the option to change his currency using a dropdown. I found a gem using which we can do this "github.com/priithaamer/geoip-rails" . Is this the correct way to do it or is there a better way?

Thanks in advance !

Answer 1

I would use the money gem for everything with money and the geocoder gem for the IP -> Geo Lookup.

The money gem is very self explaining.
