  New finder API can not be used with_exclusive_scope. You can either call unscoped to get an anonymous scope not bound to the default_scope:

  User.unscoped.where(:active => true)

  Or call unscoped with a block:

  User.unscoped do
  User.where(:active => true).all
  end

        with_scope(method_scoping, :overwrite, &block)
