问题描述
所以我有一个 >在我的路线文件末尾，例如：
It still does this even if I put the recommended routing rules for my resources post at the end of my routes file, i.e. like this:
resources :posts do
collection do
get 'confirmed' => 'posts#index', status: 'confirmed'
get 'unconfirmed' => 'posts#index', status: 'unconfirmed'
get 'corroborated' => 'posts#index', status: 'corroborated'
end
end
root to: "posts#index"
如何使状态路由不重定向到 posts＃index 操作？
How do I get the status routes to not be redirected to the posts#index action?

查看我完整的 routes.rb
Rails.application.routes.draw do
%w[privacy terms].each do |page|
get page, controller: 'info', action: page
end
resources :locations
devise_for :users, :path_names => { :sign_up => "register",
:sign_in => "login",
:sign_out => "logout",
:settings => "settings" },
:controllers => { :confirmations => "confirmations" }
devise_scope :user do
get "login", :to => "devise/sessions#new"
get "register", :to => "devise/registrations#new"
get "settings", :to => "devise/registrations#edit"
delete "logout", :to => "devise/sessions#destroy"
end
resources :posts do
collection do
get 'confirmed' => 'posts#status', status: 'confirmed'
get 'unconfirmed' => 'posts#status', status: 'unconfirmed'
get 'corroborated' => 'posts#status', status: 'corroborated'
end
end
get 'posts/:id' => redirect("/%{id}")
get '/:friendly_id', to: 'posts#show'
get 'posts/:friendly_id', to: 'posts#show'
# This supports legacy URLs e.g:
# http://www.example.com/rbt/26766-algaj-pays-tribute-to-the-honourable-roger-clarke.html
get '/rbt/:name', to: redirect {|path_params, _| "/#{path_params[:name].gsub(/^\d+\-/, '')}" }
get ':name', to: 'posts#show'
root to: "posts#index"
end

难题的最后一部分是问题的原始前提，即如何创建指向该新创建路径的链接。
The last bit of the puzzle is the original premise of the question, how do I create a link to that newly created path.
棘手的是，我想根据状态动态创建链接路径。
The tricky bit is that I want dynamically create the link_path based on the status.
例如，新路线规则的结果，我现在有 confirmed_path，corroborated_path，unconfirmed_path 。
For instance, as a result of the new routes rules, I now have confirmed_path, corroborated_path, unconfirmed_path.
但是，我正在显示它们在我看来是这样的：
However, I am displaying them in my view like so:
<span class="post-status status label<%=render partial: "shared/color", locals: {post: post.status }%>"><%= post.status.try(:upcase) %></span>
我尝试这样做：
<span class="post-status status label<%=render partial: "shared/color", locals: {post: post.status }%>"><%= link_to post.status.try(:upcase), post.status.path %></span>
但这给了我未定义的方法路径错误。
在正常情况下，我只是简单地进行字符串插值，而Ruby会渲染当前字符串。鉴于Ruby应该解析此路径，因此我怀疑它是否行得通。
In a normal instance, I would simply do string interpolation and Ruby would render the current string. Given that Ruby is supposed to parse this path, I doubt that would work.
因此，如何获取该视图以自动生成 confirmed_path，corroborated_path ，根据 post.status 是什么动态地确定路径吗？
So how do I get that view to automagically generate confirmed_path, corroborated_path, unconfirmed_path dynamically based on what post.status is?
推荐答案
您看到的是迷路。在这里调用 posts / confirmed 将转到 posts＃show ，而不是您的 posts＃index 方法代替。原因是操作包优先考虑从上到下的路由，并且由于您的路由是这样定义的：
As you see you are lost in routes. Here calling posts/confirmed will go at posts#show instead of your posts#index method instead. The reason is action pack give priority of routes from top to bottom, and since your routes are defined like this:
resources 'posts'
get 'posts/:id' => redirect("/%{id}")
get '/:friendly_id', to: 'posts#show'
get 'posts/:friendly_id', to: 'posts#show'
所有帖子/未确认， posts / confirmed 等永远不会使用index方法，因为它将与 posts＃show 然后与获取'posts /：friendly_id'，以：'posts＃show'。
All posts/unconfirmed, posts/confirmed, etc will never make to the index method as it will be matched with posts#show, and then with get 'posts/:friendly_id', to: 'posts#show'.
现在，即使您将所有 get 路由到顶部，它将永远不会使用您以后要定义的其他方法，因为所有帖子/未确认， posts / confirmed 等将与 get'posts /：id'=>匹配。 redirect（ /％{id}）并将被重定向为 /已确认， /未确认等。
Now, even if you move your all get routes to top, it will never make it to other methods you might wanna define later, as all posts/unconfirmed, posts/confirmed, etc will be matched with get 'posts/:id' => redirect("/%{id}") and will be redirected as /confirmed, /unconfirmed, etc.
推荐的方法是为各个路线使用单独的方法，因为将来您可能还希望确认的帖子与证实的帖子具有不同的行为。为此，您的路线将如下所示：
Recommended way is to have separate methods for individual routes, since in future you also might want to have a different behavior for confirmed posts than corroborated posts. For that your routes will look like this:
resources :posts do
collection do
get 'confirmed'
get 'unconfirmed'
get 'corroborated'
end
end
运行 $耙路| grep帖子会给出：
confirmed_posts GET /posts/confirmed(.:format) posts#confirmed
unconfirmed_posts GET /posts/unconfirmed(.:format) posts#unconfirmed
corroborated_posts GET /posts/corroborated(.:format) posts#corroborated
posts GET /posts(.:format) posts#index
POST /posts(.:format) posts#create
new_post GET /posts/new(.:format) posts#new
edit_post GET /posts/:id/edit(.:format) posts#edit
post GET /posts/:id(.:format) posts#show
PATCH /posts/:id(.:format) posts#update
PUT /posts/:id(.:format) posts#update
DELETE /posts/:id(.:format) posts#destroy
，然后创建单独的方法，即已确认，未确认，已确认等。
and then you create separate methods, i.e. confirmed, unconfirmed, corroborated etc.
但是，您始终可以将所有这些路线都指向这样的路线（
However, you can always point all these routes to one like this(which is not recommended):
resources :posts do
collection do
get 'confirmed' => 'posts#status', status: 'confirmed'
get 'unconfirmed' => 'posts#status', status: 'unconfirmed'
get 'corroborated' => 'posts#status', status: 'corroborated'
end
end
然后在您的 PostsController 中：
def status @posts = Post.published.where(status: params[:status]) end
更新：将您的route.rb更改为-
UPDATE: Change your routes.rb to this -
Rails.application.routes.draw do
%w[privacy terms].each do |page|
get page, controller: 'info', action: page
end
resources :locations
devise_for :users, :path_names => { :sign_up => "register",
:sign_in => "login",
:sign_out => "logout",
:settings => "settings" },
:controllers => { :confirmations => "confirmations" }
devise_scope :user do
get "login", :to => "devise/sessions#new"
get "register", :to => "devise/registrations#new"
get "settings", :to => "devise/registrations#edit"
delete "logout", :to => "devise/sessions#destroy"
end
resources :posts
get '/confirmed' => 'posts#status', status: 'confirmed', as: :confirmed
get '/unconfirmed' => 'posts#status', status: 'unconfirmed', as: :unconfirmed
get '/corroborated' => 'posts#status', status: 'corroborated', as: :corroborated
get 'posts/:id' => redirect("/%{id}")
get '/:friendly_id', to: 'posts#show'
get 'posts/:friendly_id', to: 'posts#show'
# This supports legacy URLs e.g:
# http://www.example.com/rbt/26766-algaj-pays-tribute-to-the-honourable-roger-clarke.html
get '/rbt/:name', to: redirect {|path_params, _| "/#{path_params[:name].gsub(/^\d+\-/, '')}" }
get ':name', to: 'posts#show'
root to: "posts#index"
end
确保您的 PostsController 中具有 status 方法：
def status # your code for fetching posts goes here! render text: params[:status] # this is to show an example that `status` is set properly end
