Compare with:

redirect_back(fallback_location:, allow_other_host: true, **args)

Redirects the browser to the page that issued the request (the referrer) if possible, otherwise redirects to the provided default fallback location.

The referrer information is pulled from the HTTP Referer (sic) header on the request. This is an optional header and its presence on the request is subject to browser security settings and user preferences. If the request is missing this header, the fallback_location will be used.

redirect_back fallback_location: { action: "show", id: 5 }
redirect_back fallback_location: @post
redirect_back fallback_location: "http://www.rubyonrails.org"
redirect_back fallback_location: "/images/screenshot.jpg"
redirect_back fallback_location: posts_url
redirect_back fallback_location: proc { edit_post_url(@post) }
redirect_back fallback_location: '/', allow_other_host: false

Options

:fallback_location - The default fallback location that will be used on missing Referer header.
:allow_other_host - Allow or disallow redirection to the host that is different to the current host, defaults to true.

All other options that can be passed to redirect_to are accepted as options and the behavior is identical.

Parameters

fallback_location keyreq
allow_other_host key = true
args keyrest
