Continuing the discussion from Where can I change the currency from symbol to 3 letter form?:
Instead of using the humanized_money_with_symbol helper, you need to render the Money object yourself. Something like this:
.amount
= listing.price.format(with_currency: false, symbol: false)
.currency
= listing.price.currency.iso_code
(Btw. I didn’t test the code above, so it may contain error)
Have a look at Ruby Money gem for more information about different formatting options.
