Question

I would like to write inclusion validator like below:

validates :application_date,
  inclusion_of: { in: Date.today..20.years.from_now }

# Schema
#  application_date       :date

But I get

bad value for range

Answer 1

The reason you’re getting that error is because 20.years.from_now is returning a datetime object (ActiveSupport::TimeWithZone) and Date.today returns a date. Therefor your range will not work because it’s using two different object types. You might be able to fix it by converting the latter to a date:

Date.today..20.years.from_now.to_date
