Rails的routes.rb中不工作根據需要與命名路由

Question

我有這樣的代碼鏈接到一個新的角色：

<%= link_to "New Persona", genesis_path, class: "new-persona-button" %> 

我的routes.rb文件：

Bazleyapp::Application.routes.draw do 

    resources :users, only: [:index, :create] 
    resources :personas, only: [:index, :create] 

    root      'static_pages#home' 

    get  'signup',     to: 'users#new' 
    get  '/:callsign',    to: 'users#show',  as: :user 
    get  '/:callsign/settings', to: 'users#edit',  as: :edit_user 
    patch '/:callsign',    to: 'users#update', as: :update_user 
    delete '/:callsign/terminated', to: 'users#destroy', as: :destroy_user 

    get  'genesis',    to: 'personas#new' 
    get  '/:callsign',    to: 'personas#show',  as: :persona 
    get  '/:callsign/settings', to: 'personas#edit',  as: :edit_persona 
    patch '/:callsign',    to: 'personas#update', as: :update_persona 
    delete '/:callsign/terminated', to: 'personas#destroy', as: :destroy_persona 

end 

點擊新角色按鈕產生此錯誤：

Started GET "/genesis" for ::1 at 2014-12-03 00:25:38 +0000 
Processing by UsersController#show as HTML 
Parameters: {"callsign"=>"genesis"} 
User Load (0.4ms) SELECT "users".* FROM "users" WHERE "users"."callsign" = $1 LIMIT 1 [["callsign", "bazzer"]] 
User Load (0.3ms) SELECT "users".* FROM "users" WHERE "users"."callsign" = $1 LIMIT 1 [["callsign", "genesis"]] 
Completed 500 Internal Server Error in 21ms 

NoMethodError (undefined method `activated' for nil:NilClass): 
app/controllers/users_controller.rb:17:in `show' 

這意味着當它應該擊中genesis_p時它正在觸及user_path（users＃show） ATH。但我已經告訴它<%= link_to "New Persona", genesis_path, class: "new-persona-button" %>打的起源路徑。我很困惑。錯誤在哪裏？

Answer 1

將

get 'genesis', to: 'personas#new' 

get '/:callsign', to: 'users#show', as: :user 

你必須知道的路由文件是從上往下看之前。

我不認爲你這裏有什麼事，你要覆蓋幾路工作。您可能需要考慮將它們放在單獨的名稱空間中，以便它們是唯一的。

例子：

Bazleyapp::Application.routes.draw do 

    resources :users, only: [:index, :create] 
    resources :personas, only: [:index, :create] 

    root      'static_pages#home' 

    namespace :users do 
    get  'signup',     to: 'users#new' 
    get  '/:callsign',    to: 'users#show',  as: :user 
    get  '/:callsign/settings', to: 'users#edit',  as: :edit_user 
    patch '/:callsign',    to: 'users#update', as: :update_user 
    delete '/:callsign/terminated', to: 'users#destroy', as: :destroy_user 
    end 

    namespace :personas do 
    get  'genesis',    to: 'personas#new' 
    get  '/:callsign',    to: 'personas#show',  as: :persona 
    get  '/:callsign/settings', to: 'personas#edit',  as: :edit_persona 
    patch '/:callsign',    to: 'personas#update', as: :update_persona 
    delete '/:callsign/terminated', to: 'personas#destroy', as: :destroy_persona 
    end 
end 

這樣，這些路由你不同的路徑。

您還可以將塊添加到資源，而不必把它分開。例如：

resources :users, only: [:index, :create] do 
    get  'signup',     to: 'users#new' 
    get  '/:callsign',    to: 'users#show',  as: :user 
    get  '/:callsign/settings', to: 'users#edit',  as: :edit_user 
    patch '/:callsign',    to: 'users#update', as: :update_user 
    delete '/:callsign/terminated', to: 'users#destroy', as: :destroy_user 
end
