Question

I am running an application on Ruby On Rails (3.1) and need to handle translations into various languages. I got my controller texts properly handled using the I18N feautures, but what about validations in models, especially those like this:

validate :valid_quantities?

def valid_quantities?
    if self.quantity*self.unitprice < 1.00
    errors.add("The transaction value", "is < 1.00")
    return false
end

How would I code this to provide support for other languages?
In addition, how to I handle the formatting of the numbers? I cannot call the ActionView helpers and user e.g. number_to_currency

Answer 1

Ok, I made partial progress, looks like the following works:

Change the code in the model validation to

errors.add(" ",I18n.t(:valid_quantities,:amount=>1.00))

Enter the translation into de.yml

de:
    valid_quantities: "Der Mindestwert einer Order ist %{amount}"

But I am still looking for a way to format that number correctly (1.00 for English, 1,00 for German).
