Allow ''.'' to be a part of identifier, not a separator of format

Hi,

I have a question about available characters for url in Rails3.
Is it possible to include ''.'' as identifier of resources?


Background
----------

I want to use title name as identifier instead of id in url path, for
example:

   http://localhost:3000/movies/Avatar

And I want to allow ''.'' to appear in url, such as:

   http://localhost:3000/movies/Avatar2.0

But it raises ActionController::RoutingError exception.


What I did
----------

   $ rails --version
   Rails 3.0.0.beta2
   $ rails g scaffold Movie title:string description:string
   $ rake db:migrate
   $ vi app/models/movie.rb
   $ cat app/models/movie.rb
   class Movie < ActiveRecord::Base
     def to_param
       title
     end
   end
   $ rails c
   irb> Movie.create(:title=>"Avatar", :description=>"3D
Movie")


I accessed to http://localhost:3000/movies/Avator and page is shown
correctly.

But when I create another movie with title ''Avator2.0'',
it causes ActionController::RoutingError.

"2010-04-16 06:16:39", updated_at: "2010-04-16
06:50:31">}

I guess that ''.'' may cause the error, but I want to allow to
use ''.''
in url.
Is it possible to use ''.'' in url?

Re: Allow ''.'' to be a part of identifier, not a separator of format

In your ./config/routes.rb, you could do something like:

  ...
  map.connect ''/movies/:title'',
    :controller=>''movies'',
    :action=>''by_title'',
    :requirements=>{:title=>/[-_+.a-z0-9]+/i}

  ...

See Regular Expressions and Parameters on
http://api.rubyonrails.org/classes/ActionController/Routing.html for
more info.
