Using Money-Rails Gem for Multiple Currencies [Rails 4]

Question

I have a Rails 4 app using the money-rails gem to define money objects. I have a money object called default_price_cents and a currency column on the User model to define currencies for each individual user (as seen here):

class AddDefaultsToUser < ActiveRecord::Migration
  def change
    add_money :users, :default_price
    add_column :users, :currency, :string
  end
end

My user.rb has the following lines:

register_currency :usd

monetize :default_price_cents, with_model_currency: :default_price_currency

Users then define their currency in registration (HAML):

.form-group
  = f.label :currency
  = f.select :default_price_currency, [['USD','usd'],['CAD','cad'],['DKK','dkk']]

I have tried to have this set with both :default_price_currency as well as :currency.

In my view, I have:

humanized_money_with_symbol @default_price

The Problem:

When this I display the default price in my view, it for some reason uses the currency I have defined with register_currency in my model, instead of using the currency defined by the user upon registration. How do I get the app to refer to the user defined currency instead of the registered currency for that model?

SOLVED!

Well, embarrassingly, writing this post helped me to find the answer only a few seconds later. I'll leave it up for anyone who may need it.

I've changed this line in user.rb:

monetize :default_price_cents, with_model_currency: :default_price_currency

to look like

monetize :default_price_cents, with_model_currency: :currency

as well as changed the default_price_currency to currency in my views.
