Rails set default DateTime to now

Question

In my app I have teams and each team has a game time every week. I want the game times to be set to \'now\' as a default. My table is set up like so

create_

You're going to run into problems settings the default date time in the migration. This is because DateTime.now will be evaluated based upon when the migrate runs, not when the record is created!

To fix that you'll need to create an ActiveRecord callback in order to set wk1_time like so:

before_create :set_default_wk1_datetime
def set_default_wk1_datetime
  self.wk1_time = DateTime.now
end
