A cleaner way to do this would be to override the setter for hours:
def hours=(value)
if value =~ /:/
converted_value = ... # do the conversion here
super(converted_value)
else
super
end
end
As an upside, this means that setting hours will *always* return the
correct value, even before the before_validation callback runs.
