Date.new for leap years

rubyonrails-core

Hey guys,

Every time I build a calendar system or anything with an annually recurring set of dates, I find myself doing this all the time to avoid getting invalid date exceptions:

year = Date.today.year

if (year % 4 != 0) && rhs.month == 2 && rhs.day == 29 rday = 28 else rday = rhs.day end

date = Date.new(year, rhs.month, rday)

Would anybody be interested in a patch so we could just do:

Date.new(year, rhs.month, rhs.day, :fix_leap_year => true)

Maybe even make :fix_leap_year => true the default behavior?

Thanks, Ryan

Where does ‘rhs’ come from?

In this case it’s a model with month and day attributes.

Oh, I get your problem. You want Date.new to change 29 to 28 if it was given february, but outside of a leap year.

I don’t think this is the right forum for this discussion. Date is actually part of the Ruby library. Try one of the lists at http://www.ruby-lang.org/en/community/mailing-lists/.
