Validation: comparing two fields

Rails
1

What is the nicest way to validate the values of
two fields against each other:

For example:

start_date < end_date

where both could be nil.

in your model

protected
def validate
errors.add(:end_date, “can’t come before the Start date”) if end_date
< start_date
end
