如何命名嵌套的控制器和路由？

Question

I'm working on creating a wiki app from scratch with the following organization:

Main Controller: Wiki Nested Controller: WikiCategories Nested Controller: WikiArticles

In my config/routes.rb I have:

resource :wiki do
  resources :wiki_categories, :as => :categories
  resources :wiki_articles, :as => :articles
end

I've chosen to name the categories and articles controllers as WikiCategories and WikiArticles to differentiate from other category and article controllers that I want to make in the future under a blog nesting.

This gives me the following routes:

/wiki/wiki_categories/new
/wiki/wiki_articles/new

Is there any way to rewrite the routes to be:

/wiki/categories/new
/wiki/articles/new

... while still using the WikiCategories and WikiArticles controller names?

Answer 1

Yes it is by specifying the controller , the resource can then be named whichever way you like.

resource :wiki do
  resources :categories, controller: 'wiki_categories'
  resources :articles, controller: 'wiki_articles'
end

Please see the guide for further information.

Answer 2

You can use the path: option as follows:

resource :wiki do
  resources :wiki_categories, path: 'categories', :as => :categories
  resources :wiki_articles, path: 'articles', :as => :articles
end

Which will give you:

/wiki/categories/...
/wiki/articles/...

See Translated Paths section of the guides for further details.

I've chosen to name the categories and articles controllers as WikiCategories and WikiArticles to differentiate from other category and article controllers that I want to make in the future under a blog nesting.

IMO, it seems like you're bucking convention a bit. As discussed in Controller Namespaces and Routing , why not do:

namespace :wiki do
  resources :categories, :articles
end

Which will give you:

    wiki_categories GET    /wiki/categories(.:format)              wiki/categories#index
                    POST   /wiki/categories(.:format)              wiki/categories#create
  new_wiki_category GET    /wiki/categories/new(.:format)          wiki/categories#new
 edit_wiki_category GET    /wiki/categories/:id/edit(.:format)     wiki/categories#edit
      wiki_category GET    /wiki/categories/:id(.:format)          wiki/categories#show
                    PATCH  /wiki/categories/:id(.:format)          wiki/categories#update
                    PUT    /wiki/categories/:id(.:format)          wiki/categories#update
                    DELETE /wiki/categories/:id(.:format)          wiki/categories#destroy
      wiki_articles GET    /wiki/articles(.:format)                wiki/articles#index
                    POST   /wiki/articles(.:format)                wiki/articles#create
   new_wiki_article GET    /wiki/articles/new(.:format)            wiki/articles#new
  edit_wiki_article GET    /wiki/articles/:id/edit(.:format)       wiki/articles#edit
       wiki_article GET    /wiki/articles/:id(.:format)            wiki/articles#show
                    PATCH  /wiki/articles/:id(.:format)            wiki/articles#update
                    PUT    /wiki/articles/:id(.:format)            wiki/articles#update
                    DELETE /wiki/articles/:id(.:format)            wiki/articles#destroy

Then, create namespaced controllers, something like:

app/controllers/wiki/categories.rb

class Wiki::CategoriesController < ApplicationController
  ...
end

and

app/controllers/wiki/articles.rb

class Wiki::ArticlesController < ApplicationController
  ...
end
