How to remove controller names from rails routes?

Question

I would like to trim down the routes on my application so that:

http://myapplication.com/users/peter/questions/how-do-i-create-urls

becomes...

http://myapplication.com/peter/how-do-i-create-urls

I have a users controller and would like it to be resourceful. Users also have a nested resource called questions.

Basic routes file

Without any URL trimming, the routes file looks like this:

... resources :users do   resources :questions end 

However the URLs from this take the form of

http://myapplication.com/users/peter/questions/how-do-i-create-urls

rather than

http://myapplication.com/peter/how-do-i-create-urls

Partial success I have tried doing the following:

... resources :users, :path => '' do   resources :questions end 

This works and produces:

http://myapplication.com/peter/questions/how-do-i-create-urls

However if I try:

... resources :users, :path => '' do   resources :questions, :path => '' end 

Then things start to go wrong.

Is this the right approach and if so, can it be made to work with nested resources too?

Answer 1

The way you are doing it should work. I don't know what problem you are experiencing but if you copied the example code from your app directly then it might be because of the extra end that you have put in your routes. It should probably look like this:

resource :users, :path => '' do   resource :questions, :path => '' end 

Another thing that could be the cause and that you need to be vary careful about is that these routes pretty much catches all requests and you should have them last in your routes.rb so that other routes matches first. Take this scenario for example:

resource :users, :path => '' do   resource :questions, :path => '' end  resources :posts 

If you do it this way then no request will ever be routed to the Posts controller since a request to /posts/1 will be sent to the Questions controller with :user_id => 'posts', :id => 1

Edit:

Also, I now noticed that you use resource instead of resources. Don't know if that is intended or if it is a mistake.

Thanks to both @mark and @DanneManne for their help. With their input and a little more tweaking I got it all working. It's not exactly trivial but I'm not sure you could make it much shorter either:
