Catching that 0.0 value was the right direction to look in:
def convert_hours
if hours_before_type_cast && hours_before_type_cast =~ /:/
hrs, mins = hours_before_type_cast.scan( /(\d*):(\d*)/ ).first
self.hours = BigDecimal( ( hrs.to_f + ( mins.to_f / 60.0 ) ), 4 )
end
end
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.
