In lib/friendly_id/base.rb:252, as introduced in SHA: aa3b4a6:

    def dup
      super.tap { |duplicate| duplicate.slug = nil }
    end

However, suppose we have a User with just friendly_id :login - no extra slug. #slug= is not defined, and therefore some_user.dup fails.

My patch just makes the dup check if slug= is defined before using it.

Could you bump the version # etc so it gets published?

@norman @parndt I suspect this is broken.

Shouldn't we override #dup only when including the FriendlyId::Slugged module? Then, I think we should not invoke #slug= explicitly as that can be changed through configuration.

Will try to reproduce and, file an issue.
