Question

How to force Rails to consider a param with a dot in the value like google.com (e.g. /some_action/google.com) a single param and not "id" => "google", "format"=> "com"?

The parameter value should be "id" => "google.com"

Answer 1

By default, dynamic segments don’t accept dots – this is because the dot is used as a separator for formatted routes. However, you can add some regex requirements to the route parameters. Here, you want to allow the dots in the parameters.

match 'some_action/:id' => 'controller#action', :constraints  => { :id => /[0-z\.]+/ }

And in rails 2.3:

map.connect 'some_action/:id', :controller => 'controller', :action => 'action',  :requirements => { :id => /[0-z\.]+/ }
