I'm running into a problem with the ActiveRecord::Base "==" method
defined here (it's 2.3.2, but it looks the same in older versions
# File rails-2.3.2/activerecord/lib/active_record/base.rb, line
2816: def ==(comparison_object)
2817: comparison_object.equal?(self) ||
2818: (comparison_object.instance_of?(self.class) &&
2819: comparison_object.id == id &&
Because of the last criteria (!comparison_object.new_record?),
something like this happens... say i have a new record and an existing
record (different objects) and compare them:
new == old
old == new
If this is intentional, can someone please explain why this is?
Also what is the rational of only comparing the ID and not the all the
values too and why does it matter if it's a new record or not?
