Question

I am using Ruby on Rails 3. In my project I have many classes and some of those are stated in the routes.rb file like the following:

#routers.rb
resources :users

namespace "users" do
  resources :profiles
  ...
end

With the above code I can access the following URLs:

<my_web_site>/users/1
<my_web_site>/users/1/edit
...
# and also
<my_web_site>/users/profiles/1
<my_web_site>/users/profiles/1/edit
...

What I would like to do is to redirect some URL requests to others URL but if in the routes.rb file I redirect all those, some controller actions will not work properly because also those requests are redirected (GET, POST, …).

How can I solve this issue?

P.S.: I know that (maybe) my router statements are wrong, but at the moment I am looking for a easy solution too the problem. However suggestions about this matter are welcome.

Ok, looks like you want to set up a redirection that will only apply for to a given path and just one HTTP verb. This seems to be what you are looking for:

#routers.rb
resources :users

match "/users/profile/:id" => redirect("/profiles/%{id}"), :via => :get

namespace "users" do
  resources :profiles
  ...
end

Based on this routes every GETrequest hitting /users/profile/1 will be redirected to /profiles/1 while any POST, PUT or DELETE requests won’t be suffering the redirection.

The :via param will execure the redirection only if the request method math the given value. It also accepts an array of verbs so, for example, you can redirect :via => [:post, :put]

If you add more detailed information about the specific redirections that you need we can create a better example.
