I''m working on a project (Active Admin) that needs to be able to build links on the page (e.g. pagination) that include arbitrary query parameters that the user has entered. Since `url_for` symbolizes any keys passed to it, for obvious memory concerns you can''t just pass the entire params hash. In Rails 3.2, however, you can do this: include Rails.application.routes.url_helpersurl_for action: ''index'', controller: ''employees'', host: ''foo.bar'', params: {''eee'' => 3}# => "http://foo.bar/employees?eee=3"Symbol.all_symbols.map(&:to_s).include? ''eee''# => false In other words, you can pass `params: request.query_parameters` to `url_for` to avoid the potential DOS issue. However we still support Rails 3.0 and 3.1, and they completely ignore `:params`. Save for monkeypatching, has anyone found a way to safely provide this functionality?
