collection#replace does not return it's predecessor's value

Array#replace: http://corelib.rubyonrails.org/c...

Array#replace returns the new array, Collection#replace returns nil and probably false or an Integer because of the total_entries conditional. I believe Collection#replace should simply add-on to Array#replace while retaining all of it's original uses. Here is the simple fix:

    def replace(array)
      value = super
      # The collection is shorter then page limit? Rejoice, because
      # then we know that we are on the last page!
      if total_entries.nil? and length > 0 and length < per_page
        self.total_entries = offset + length
      end
      value
    end
