ruby - Rails 4 - Updating an attribute based on time / date -

i on rails 4.

i have room model active? attribute. when creating room, users can set different times , dates want room active.

my goal: if user creates room dates mar 3 - mar 5, active? set true on mar 3 , false on mar 5. same goes if user sets times (ex. 10:00 - 5:00 pm)

what best way go this? having trouble finding documentation. appreciate if point me in right direction.

it's unclear how storing start , end date's, assuming have start_date , end_date, define active? method follows:

def active?     date.current >= start_date && date.current < end_date end 

replace date datetime if needed
