Restful routes, nested resources (and /admin)

rubyonrails-talk

Hello,

I’m now playing with REST and Rails (with Rails 1.2.1).

I have the following routes in my route.rb :

map.with_options :path_prefix => “/admin”, :name_prefix => “admin_” do |m|

m.resources :requests, :controller => “admin/requests” end

This give me a RESTful /admin/requests controller.

In my application, a Request has many Histories. How can I add the correct route to have something like that :

/admin/requests/24/histories.

Without the /admin, it would simply look like this : map.resources :requests do |request| request.resources :histories end

But with the /admin, everything becomes to be confused for me.

Any help would be greatly appreciated.

Thanks in advance, Thomas.

try this:

map.with_options :path_prefix => "/admin", :name_prefix => "admin_" do |m|   m.resources :requests, :controller => "admin/requests" do |req|     req.resources :histories   end end

Hello Ed, Thanks for your answer.

When I do this : map.with_options :path_prefix => “/admin”, :name_prefix => “admin_” do |m| m.resources :requests, :controller => “admin/requests” do |request|

  request.resources :histories
end

end

And in my view I do this : <%= admin_histories_url %>

I get this error : undefined local variable or method `admin_histories_url’

So I’ve changed to that : map.with_options :path_prefix => “/admin”, :name_prefix => “admin_” do |m| m.resources :histories, :controller => “admin/histories” m.resources :requests, :controller => “admin/requests” do |request| request.resources :histories end end

And now : <%= admin_histories_url %> give me this : http://0.0.0.0:3000/admin/histories

If I try this in my view : <%= admin_histories_url(@request) %>

I get this error : You have a nil object when you didn’t expect it! The error occurred while evaluating nil.to_sym

So I don’t think it solves the problem. Any idea? Thanks, Thomas.

It seems to work with this in my route.rb : map.with_options :path_prefix => “/admin”, :name_prefix => “admin_” do |m| m.resources :requests, :controller => “admin/requests” do |request|

  request.resources :histories, :path_prefix => "/admin/requests/:request_id", :name_prefix => "admin_"
end

end

If I try that in my view : <%= admin_histories_url(@request) %>

I now get this : http://0.0.0.0:3000/admin/requests/24/histories

If anybody wants to comment this solution, he is more than welcome. I’m not sure to do the right thing here.

Thanks, Thomas.

so if you do this: <%= admin_histories_url(@request) %>

you should get something like:   "/admin/requests/1/histories"

if you do this:   <%= admin_histories_url(@request, @history) %>

you should get something like:   "/admin/requests/1/histories/2"

You have achieved what you requested in your original email, no?

Yes, that’s it. But there is still an error in my solution.

Here is the final (I hope) solution : map.with_options :path_prefix => “/admin”, :name_prefix => “admin_” do |m| m.resources :requests, :controller => “admin/requests” do |request| request.resources :histories, :path_prefix => “/admin/requests/:request_id”, :name_prefix => “admin_”, :controller => “admin/histories”

end

end

In my previous solution, I forgot ":controller => “admin/histories”. Thanks for your help.

Everybody is still welcome to comment this solution. Thomas.

I ran across this the other day and was confused about why the with_options options don’t trickle down but I guess it doesn’t actually matter why since they don’t.
