Redirect to canonical route in without trailing slash in Rails 3

Question

On Rails 3, I\'m trying to redirect from a URL without a trailing slash to the canonical URL that has a slash.

match \"/test\", :to => redirect(\"/test/\"         


        

Answer 1

There is an option in ActionDispatch called trailing_slash you can use to force the trailing slash at the end of the URL. I'm not sure if it can be used in the routing definition.

def tes_trailing_slsh
  add_host!
  options = {:controller => 'foo', :trailing_slash => true, :action => 'bar', :id => '33'}
  assert_equal('http://www.basecamphq.com/foo/bar/33/', W.new.url_for(options) )
end

In your case, the best way is to use Rack or your web server to execute the redirect. In Apache, you can add a definition such as

RewriteEngine on
RewriteRule ^(.+[^/])$ $1/  [R=301,L]

To redirect all routes without a trailing slash to the corresponding one with trailing slash.

Or you can use rack-rewrite to perform the same task in your Rails app at Rack level.
