def render
  if !value[:enabled]
    {self.class.param_name => false}
  elsif value[:excludes].present?
    {self.class.param_name => value.slice(:includes, :excludes).reject { |_, v| v.blank? }}
  elsif value[:includes].present?
    {self.class.param_name => value[:includes]}
  end
end

#update!(other_value) ⇒ {Symbol => Array<String>, true, false}

If array or simple string/symbol is passed, it is treated as a part of includes array and gets concatenated with it. In case of hash, respective values are concatenated as well.
