each_instance doesn't handle enum attributes?

First of all, great gem, love it 👍

I've only run into a problem with enum attributes in ActiveRecord. If I define a model with an enum attribute, .each() outputs the symbolic enum value, but .each_instance() outputs the underlying numeric value. e.g.

class User < ApplicationRecord
enum gender: [:male, :female]
end

User.all.each {|u| puts u.gender} # Outputs "male", "male", "female"
User.all.each_instance {|u| puts u.gender} # Outputs 0, 0, 1

Thanks, @chickenburgers (what a cool name!)

I looked on this again today. As far as I can tell, I'm doing the correct thing in instantiating the record. The enum's act as if they aren't defined. Could be an activerecord issue? Or there is a newer way to to it? Frustrating. 😢

@afair I'm wondering why column_types is used in each_instance or each_instance_batch for activerecord version greater than 4 (5.2.3 to be precise). If I instantiate the object with klass.send(:instantiate, row) or simply klass.instantiate(row) (without column_types), it'd map the enum correctly while instantiating the AR object. Am I missing something here?
