Rails 3 : route a resource to another name

问题

I have a CRUD controller for a model.

Doing resources :foo allows me to route on /foo/:id, etc. for calling actions.

I want add a route for a translation of 'foo' in another language. Let's say 'toto'. So I want all the /toto/:id, etc., routes to act exactly like the /foo/:id, etc., routes.

How may I achieve that?

回答1:

You can add a new resource and specify foo as the controller:

resources :toto, :controller=>"foo"

This will point all the actions to "foo", but there is a gotcha. I think you will run into problems with the links on the page, if you are using foo_url or something like that. So you would have to figure out a way to create the URLs dymanically based on the controller in "request.path".

回答2:

This will let you rename paths seen by the user but keep the original name of your controllers in the code:

scope(:path_names => { :new => "neu", :edit => "bearbeiten" }) do
  resources :categories, :path => "kategorien"
end

From the Ruby on Rails Guides

回答3:

If I understand you correctly, you want to just use another path.

resources :foo, path: 'toto'

Now you will have:

GET /toto          foo#index
GET /toto/:id      foo#show
...

回答4:

You can achieve something close to this using scope:

scope ':language/' do
  resources :foo, controller: 'bar_controller'
end

This make your bar_controller a resource to anything/foo, where anything gets passed as the :language parameter.

so:

• en_US/foo
• de_DE/foo
• ja_JP/foo

all get handled by bar_controller, with the normal resource mapping, and you get params[:language] in the controller for free.
