Question

I have a model named Entree for which the new action needs a parameter, the id of another model named Cave. I don’t want to nest Entree in Cave since Cave is already nested.
What I did was declaring the resource Entree as follow in routes.rb:

resources :entrees, :except => [:new]
match "/entrees/new/:id", :to => "Entrees#new", :as => 'new_entree'

That works, but the problem is when there’s an error in the create action, I want to display the page again with the invalid input. But since there’s no new action, I must do a redirect_to new_entree_path, which does not keep the user input.

I have tried the following (simplest) route:

resources :entrees

But then the path http://localhost:3000/entrees/new/32 returns an error:

No route matches [GET] "/entrees/new/32"

The question is, how can I declare the Entree resource in the routes file with a parameter for the new action ?

Answer 1

I’m not sure if that’s a hack or not, but the following works and seems cleaner than 2-levels nesting.

resources :entrees, :except => [:new] do
  collection do
    get 'new/:id', :to => "entrees#new", :as => 'new'
  end
end

Now I can do a render "new" instead of a redirect_to.
I must say that I must have asked my question wrongly, my bad.
