带有路径前缀的浅路由?

ruby ruby-on-rails

Christoph Schiessl Joeyjoejoejr · 技术社区 · 16 年前

最近,我在一个应用程序中更改了一些嵌套资源,以使用浅路由。它工作得很好,我能够简化我的视图和控制器。

map.with_options :path_prefix => "blog" do |blog|
  blog.resources :posts do |posts|
    posts.resources :comments
  end
end

请注意,所有路由都按预期以“/blog”作为前缀。

# $ rake routes
#             posts GET    /blog/posts(.:format)                            {:controller=>"posts", :action=>"index"}
#                   POST   /blog/posts(.:format)                            {:controller=>"posts", :action=>"create"}
#          new_post GET    /blog/posts/new(.:format)                        {:controller=>"posts", :action=>"new"}
#         edit_post GET    /blog/posts/:id/edit(.:format)                   {:controller=>"posts", :action=>"edit"}
#              post GET    /blog/posts/:id(.:format)                        {:controller=>"posts", :action=>"show"}
#                   PUT    /blog/posts/:id(.:format)                        {:controller=>"posts", :action=>"update"}
#                   DELETE /blog/posts/:id(.:format)                        {:controller=>"posts", :action=>"destroy"}
#     post_comments GET    /blog/posts/:post_id/comments(.:format)          {:controller=>"comments", :action=>"index"}
#                   POST   /blog/posts/:post_id/comments(.:format)          {:controller=>"comments", :action=>"create"}
#  new_post_comment GET    /blog/posts/:post_id/comments/new(.:format)      {:controller=>"comments", :action=>"new"}
# edit_post_comment GET    /blog/posts/:post_id/comments/:id/edit(.:format) {:controller=>"comments", :action=>"edit"}
#      post_comment GET    /blog/posts/:post_id/comments/:id(.:format)      {:controller=>"comments", :action=>"show"}
#                   PUT    /blog/posts/:post_id/comments/:id(.:format)      {:controller=>"comments", :action=>"update"}
#                   DELETE /blog/posts/:post_id/comments/:id(.:format)      {:controller=>"comments", :action=>"destroy"}

新的路由配置如下所示:

map.with_options :path_prefix => "blog", :shallow => true do |blog|
  blog.resources :posts do |posts|
    posts.resources :comments
  end
end

现在,我的一些路线中缺少“/blog”前缀。

# $ rake routes
#            posts GET    /blog/posts(.:format)                  {:controller=>"posts", :action=>"index"}
#                  POST   /blog/posts(.:format)                  {:controller=>"posts", :action=>"create"}
#         new_post GET    /blog/posts/new(.:format)              {:controller=>"posts", :action=>"new"}
#        edit_post GET    /posts/:id/edit(.:format)              {:controller=>"posts", :action=>"edit"}
#             post GET    /posts/:id(.:format)                   {:controller=>"posts", :action=>"show"}
#                  PUT    /posts/:id(.:format)                   {:controller=>"posts", :action=>"update"}
#                  DELETE /posts/:id(.:format)                   {:controller=>"posts", :action=>"destroy"}
#    post_comments GET    /posts/:post_id/comments(.:format)     {:controller=>"comments", :action=>"index"}
#                  POST   /posts/:post_id/comments(.:format)     {:controller=>"comments", :action=>"create"}
# new_post_comment GET    /posts/:post_id/comments/new(.:format) {:controller=>"comments", :action=>"new"}
#     edit_comment GET    /comments/:id/edit(.:format)           {:controller=>"comments", :action=>"edit"}
#          comment GET    /comments/:id(.:format)                {:controller=>"comments", :action=>"show"}
#                  PUT    /comments/:id(.:format)                {:controller=>"comments", :action=>"update"}
#                  DELETE /comments/:id(.:format)                {:controller=>"comments", :action=>"destroy"}

我正在寻找一个解决方案,使前缀回到所有路线。我知道它正在使用名称空间( map.namespace :blog do

文件似乎表明,这种确切的行为是出于设计:

(来自 http://api.rubyonrails.org/classes/ActionController/Resources.html#M000501 )

map.with_options :path_prefix => "blog" do |blog|
  blog.resources :posts do |posts|
    posts.resources :comments, :only => [:index, :create, :new]
  end
  blog.resources :comments, :except => [:index, :create, :new]
end

#             posts GET    /blog/posts                               {:controller=>"posts", :action=>"index"}
#                   POST   /blog/posts                               {:controller=>"posts", :action=>"create"}
#          new_post GET    /blog/posts/new                           {:controller=>"posts", :action=>"new"}
#         edit_post GET    /blog/posts/:id/edit                      {:controller=>"posts", :action=>"edit"}
#              post GET    /blog/posts/:id                           {:controller=>"posts", :action=>"show"}
#                   PUT    /blog/posts/:id                           {:controller=>"posts", :action=>"update"}
#                   DELETE /blog/posts/:id                           {:controller=>"posts", :action=>"destroy"}
#     post_comments GET    /blog/posts/:post_id/comments             {:controller=>"comments", :action=>"index"}
#                   POST   /blog/posts/:post_id/comments             {:controller=>"comments", :action=>"create"}
#  new_post_comment GET    /blog/posts/:post_id/comments/new         {:controller=>"comments", :action=>"new"}
#      edit_comment GET    /blog/comments/:id/edit                   {:controller=>"comments", :action=>"edit"}
#           comment GET    /blog/comments/:id                        {:controller=>"comments", :action=>"show"}
#                   PUT    /blog/comments/:id                        {:controller=>"comments", :action=>"update"}
#                   DELETE /blog/comments/:id                        {:controller=>"comments", :action=>"destroy"}

希望这有帮助!

最简单的解决方案可能不是使用:shallow选项,而是使用其他资源定义创建相同的路由:

map.with_options :path_prefix => "blog" do |blog|
  blog.resources :posts do |posts|
    posts.resources :comments, :only => [:index, :create, :new]
  end
end
map.resources :comments, :path_prefix => "blog",
              :except => [:index, :create, :new]

其中给出了以下管线定义:

# $ rake routes
#            posts GET    /blog/posts(.:format)                       {:action=>"index", :controller=>"posts"}
#                  POST   /blog/posts(.:format)                       {:action=>"create", :controller=>"posts"}
#         new_post GET    /blog/posts/new(.:format)                   {:action=>"new", :controller=>"posts"}
#        edit_post GET    /blog/posts/:id/edit(.:format)              {:action=>"edit", :controller=>"posts"}
#             post GET    /blog/posts/:id(.:format)                   {:action=>"show", :controller=>"posts"}
#                  PUT    /blog/posts/:id(.:format)                   {:action=>"update", :controller=>"posts"}
#                  DELETE /blog/posts/:id(.:format)                   {:action=>"destroy", :controller=>"posts"}
#    post_comments GET    /blog/posts/:post_id/comments(.:format)     {:action=>"index", :controller=>"comments"}
#                  POST   /blog/posts/:post_id/comments(.:format)     {:action=>"create", :controller=>"comments"}
# new_post_comment GET    /blog/posts/:post_id/comments/new(.:format) {:action=>"new", :controller=>"comments"}
#     edit_comment GET    /blog/comments/:id/edit(.:format)           {:action=>"edit", :controller=>"comments"}
#          comment GET    /blog/comments/:id(.:format)                {:action=>"show", :controller=>"comments"}
#                  PUT    /blog/comments/:id(.:format)                {:action=>"update", :controller=>"comments"}
#                  DELETE /blog/comments/:id(.:format)                {:action=>"destroy", :controller=>"comments"}
