Hi All, Thanks for answer my question. I read http://guides.rubyonrails.org/routing.html#segment-constraints and I guess that the best way to resolve my problem is do like Jim said, put the route in match and add except constraint in resource.

But is that route any different than the show route created by resources()?

For example, /^[1-9]\d*$/ The x after the final / isn''t needed being that the begin and end tokens take care of that for you. Also, you can do all this in the context of a routes.rb using the constrains option to match. Thus, one shouldn''t have to define a method in a separate file unless there''s plan to do this for other controller actions. If this is the case, then this becomes a one line method that returns a regex. In short, the Rails 3 routing provides much of what you''re doing below out of the box.

However, one could have easily written the same thing in a single line and zero unescaped spaces.

For instance, if this is the only route in my routes.db file: match "/users/:id" => "users#show", :constraints => {:id => /[1-9]\d*/} ...then the following urls match: http://localhost:3000/users/1 http://localhost:3000/users/10 but these urls do not match: http://localhost:3000/users/a1 http://localhost:3000/users/1a http://localhost:3000/users/aa http://localhost:3000/users/01 They produce a routing error: No route matches "/users/xx" If there was no implied ''begining of string'' anchor in the regex, then the url: http://localhost:3000/users/a1 would match. And if there was no implied ''end of string'' anchor in the regex, then the url: http://localhost:3000/users/1a would match.
