Question

我正在建立一个博客。我想将帖子关联到用户。我有这样的路线设置：

resources :users do
 resources :posts
end

resources :sessions, :only => [:new, :create, :destroy]

match '/signup', :to => 'users#new' 
match '/login',  :to => 'sessions#new'
match '/logout', :to => 'sessions#destroy' 

root :to => "pages#home"

这会将帖子与用户关联起来，当我rake routes时，它看起来像这样：

user_posts GET    /users/:user_id/posts(.:format)          {:action=>"index", :controller=>"posts"}
user_posts POST   /users/:user_id/posts(.:format)          {:action=>"create", :controller=>"posts"}
new_user_post GET    /users/:user_id/posts/new(.:format)      {:action=>"new", :controller=>"posts"}
edit_user_post GET    /users/:user_id/posts/:id/edit(.:format) {:action=>"edit", :controller=>"posts"}
 user_post GET    /users/:user_id/posts/:id(.:format)      {:action=>"show", :controller=>"posts"}
 user_post PUT    /users/:user_id/posts/:id(.:format)      {:action=>"update", :controller=>"posts"}
 user_post DELETE /users/:user_id/posts/:id(.:format)      {:action=>"destroy", :controller=>"posts"}
     users GET    /users(.:format)                         {:action=>"index", :controller=>"users"}
     users POST   /users(.:format)                         {:action=>"create", :controller=>"users"}
  new_user GET    /users/new(.:format)                     {:action=>"new", :controller=>"users"}
 edit_user GET    /users/:id/edit(.:format)                {:action=>"edit", :controller=>"users"}
      user GET    /users/:id(.:format)                     {:action=>"show", :controller=>"users"}
      user PUT    /users/:id(.:format)                     {:action=>"update", :controller=>"users"}
      user DELETE /users/:id(.:format)                     {:action=>"destroy", :controller=>"users"}
    sessions POST   /sessions(.:format)                      {:action=>"create", :controller=>"sessions"}
 new_session GET    /sessions/new(.:format)                  {:action=>"new", :controller=>"sessions"}
     session DELETE /sessions/:id(.:format)                  {:action=>"destroy", :controller=>"sessions"}
                  /users/:user_id/posts/new(.:format)      {:controller=>"posts", :action=>"create"}
                  /users/:user_id/posts/:id/edit(.:format) {:controller=>"posts", :action=>"update"}
                  /users/:user_id/posts/:id(.:format)      {:controller=>"posts", :action=>"destroy"}
    signup        /signup(.:format)                        {:controller=>"users", :action=>"new"}
     login        /login(.:format)                         {:controller=>"sessions", :action=>"new"}
    logout        /logout(.:format)                        {:controller=>"sessions", :action=>"destroy"}
      root        /(.:format)                              {:controller=>"pages", :action=>"home"}

在我对路线进行任何其他更改之前，我会尝试创建新帖子，编辑和更新它们。但是，当我尝试创建，编辑或更新帖子时，我会收到错误：

No route matches "/users/1/posts/15/edit"
No route matches "/users/1/posts/new"

然后我玩了一下并将其添加到我的路线中：

match '/users/:user_id/posts/new', :to => 'posts#create'
match '/users/:user_id/posts/:id/edit', :to => 'posts#update'
match '/users/:user_id/posts/:id', :to => 'posts#destroy'

之后，一切正常。更新，创建，编辑等等但是我的一些测试失败了。

1) PostsController GET 'new' returns http success
 Failure/Error: get 'posts#new'
 ActionController::RoutingError:
   No route matches {:controller=>"posts", :action=>"posts#new"}
 # ./spec/controllers/posts_controller_spec.rb:13:in `block (3 levels) in <top (required)>'

2) PostsController GET 'edit' returns http success
 Failure/Error: get 'edit'
 ActionController::RoutingError:
   No route matches {:controller=>"posts", :action=>"edit"}

我知道使用这些路线一切正常，但是他们错了，我需要以其他方式路由它们吗？或者我可以在测试中改变哪些东西让它们通过？

感谢。

get 'edit' => No route matches {:controller=>"posts", :action=>"edit"}

失败，因为该路线在参数中需要:user_id。你想要：

get 'edit', :user_id => 1

顺便说一句，你似乎用match语句覆盖了'足智多谋'的路线，例如：

match '/users/:user_id/posts/new', :to => 'posts#create'

覆盖new_user_post语句创建的resources路由。你确定那是什么意思吗？您通常希望/users/:user_id/posts/new转到new操作（呈现表单）而不是create操作（处理已发布的表单）。

Rails路由和rspec测试错误
