Module: Ramaze::Helper::Redirect

Defined in:
lib/ramaze/helper/redirect.rb

Overview

Helper::Redirect actually takes advantage of Helper::Link.link_raw to build the links it redirects to. It doesn’t do much else than this:

setting a status-code of 303 and a response['Location'] = link

returning some nice text for visitors who insist on ignoring those hints :P

Usage:

redirect Rs()
redirect R(MainController)
redirect R(MainController, :foo)
redirect 'foo/bar'
redirect 'foo/bar', :status => 301

TODO:

- maybe some more options, like a delay
