I need to show all my elements on the same page. In routes:

  namespace :nourishment do
   resources :diets do
     resources :nourishment_meals, :controller => 'meals'
     get 'nourishment_meals/show_all_meals' => 'meals#show_all_meals', as: "show_all_meals"
   end
  end

which will generate:

nourishment_diet_nourishment_meals_path  GET     /nourishment/diets/:diet_id/nourishment_meals(.:format)     nourishment/meals#index
POST     /nourishment/diets/:diet_id/nourishment_meals(.:format)     nourishment/meals#create
new_nourishment_diet_nourishment_meal_path   GET     /nourishment/diets/:diet_id/nourishment_meals/new(.:format)     nourishment/meals#new
edit_nourishment_diet_nourishment_meal_path  GET     /nourishment/diets/:diet_id/nourishment_meals/:id/edit(.:format)    nourishment/meals#edit
nourishment_diet_nourishment_meal_path   GET     /nourishment/diets/:diet_id/nourishment_meals/:id(.:format)     nourishment/meals#show
PATCH    /nourishment/diets/:diet_id/nourishment_meals/:id(.:format)     nourishment/meals#update
PUT  /nourishment/diets/:diet_id/nourishment_meals/:id(.:format)     nourishment/meals#update
DELETE   /nourishment/diets/:diet_id/nourishment_meals/:id(.:format)     nourishment/meals#destroy


[**THIS**]
    nourishment_diet_show_all_meals_path     GET     /nourishment/diets/:diet_id/nourishment_meals/show_all_meals(.:format)  nourishment/meals#show_all_meals

The problem, when I do this:

<%= link_to "Show all meals", nourishment_diet_show_all_meals_path, :class=>"button green" %>

This error raise:

Problem:


Document(s) not found for class NourishmentMeal with id(s) show_all.
Summary:
  When calling NourishmentMeal.find with an id or array of ids, each parameter must match a document 

Can someone help me?
