validates_inclusion_of no longer working the same in Rails 4.1?

The following code made sure that a time_zone chose is within the time zones in ActiveSupport::TimeZone.us_zones:

validates_inclusion_of :time_zone, in: ActiveSupport::TimeZone.zones_map(&:name)

Worked great in Rails 4.0. Just upgraded to Rails 4.1 and I'm getting this error on my index page (so just simply viewing the models):

An object with the method #include? or a proc, lambda or symbol is required, and must be supplied as the :in (or :within) option of the configuration hash

I'm guessing from that, ActiveSupport::TimeZone.zones_map(&:name) is no longer a valid value for the in property?

Solution

  • try adding .keys ?

    validates :time_zone, 
  inclusion: { 
    in: ActiveSupport::TimeZone.zones_map.keys 
  }
