(for translation support, etc.). If the model is not extended, it can be
accessed through the Currency.model attribute.
Money class

>>> price = Money(100, 'USD')
>>> print(price)
'$100.00'
>>> in_eur = price.convert_to('EUR')
>>> print(in_eur)

eur = currency.model(
name='Euro',
code='EUR',
sign='€',
value=1,
format_str='{:,.2f} €'
)
db.session.add(eur)
