的Ruby-on-軌道 - 破壞 - 錯誤：沒有路由匹配[GET]

我使用destroy的Ruby-on-軌道 - 破壞 - 錯誤：沒有路由匹配[GET]

在我看來，我有：

#delete_archive_modal.modal.fade 
.modal-header 
    %h3 
    %i.icon-exclamation-sign 
    Attention 
.modal-body 
    %p= "Are you sure you want to delete this portal?" 
.modal-footer 
    %a.btn{"data-dismiss" => "modal", :href => "#"} Cancel 
    = link_to 'Delete', delete_portal_path(portal)

路線：

resources :portals do 
resources :pill_tabs, only: [:show, :edit] 

resources :page_urls do 
    collection do 
    get :redirects 
    end 
end 

resources :zero_touch_configs do 
    member do 
    get :history 
    end 
end 

member do 
    get :navigation 
    get :history 
    get :sitemap 
    get :url_list 
    post :generate_sitemap 
    post :add_modules 
    post :archive 
    post :delete 
end 

collection do 
    get :index, path: '/' 
    get :new, path: '/new(/:portal_type)' 
    get :accessible_sites 
    get :archive_index 
    get :delete 
end

並在我的控制器中：

def destroy 
    @portal = Portal.find(params[:id]) 
    @portal.destroy 
    flash[:notice] = 'Portal deleted successfully.' 
    redirect_to action: :archive_index 
end

routes：

           portals GET  /portals(.:format)                         portals#index 
                 GET  /portals/new(/:portal_type)(.:format)                     portals#new

          edit_portal_stack_wrapper GET  /portals/:portal_id/stack_wrappers/:id/edit(.:format)                 stack_wrappers#edit 
           portal_stack_wrapper GET  /portals/:portal_id/stack_wrappers/:id(.:format)                  stack_wrappers#show 
                 PATCH  /portals/:portal_id/stack_wrappers/:id(.:format)                  stack_wrappers#update 
                 PUT  /portals/:portal_id/stack_wrappers/:id(.:format)                  stack_wrappers#update 
                 DELETE /portals/:portal_id/stack_wrappers/:id(.:format)                  stack_wrappers#destroy 
         history_portal_config_bundle GET  /portals/:portal_id/config_bundles/:id/history(.:format)                config_bundles#history 
           portal_config_bundles GET  /portals/:portal_id/config_bundles(.:format)                   config_bundles#index 
                 POST  /portals/:portal_id/config_bundles(.:format)                   config_bundles#create 
          new_portal_config_bundle GET  /portals/:portal_id/config_bundles/new(.:format)                  config_bundles#new 
          edit_portal_config_bundle GET  /portals/:portal_id/config_bundles/:id/edit(.:format)                 config_bundles#edit 
           portal_config_bundle GET  /portals/:portal_id/config_bundles/:id(.:format)

但我得到一個路由錯誤，不知道從哪裏何去何從......

No route matches [GET] "/portals/asdg/delete"

人人都可以分享指南或指向我的文檔，可以幫助我瞭解這裏有什麼問題？

能否請您顯示來自'這裏耙routes' delete_portal_path？ – ashvin

@ashvin添加了路由。謝謝 – essentialgreen

不客氣:) – ashvin

嘗試

= link_to 'Delete', portal_path(portal), method: :delete

這裏是所有7條路線portal

   portals GET /portals(.:format)         portals#index 
         POST /portals(.:format)         portals#create 
      new_portal GET /portals/new(.:format)        portals#new 
      edit_portal GET /portals/:id/edit(.:format)      portals#edit 
       portal GET /portals/:id(.:format)        portals#show 
         PATCH /portals/:id(.:format)        portals#update 
         PUT /portals/:id(.:format)        portals#update 
         DELETE /portals/:id(.:format)        portals#destroy

而在你的路線，你有delete_portal路徑會存在，因爲

member do 
    post :delete 
end

如果你想調用這個，然後你在con中定義了這個動作的方法troller並調用此路徑method: :post

但是在RESTful路由中刪除動作總是有DELETE方法，參見上面的路由。

謝謝@ashvin！我如何在控制器中定義方法？ 'def delete'？ – essentialgreen

是定義控制器中的新方法'def delete＃爲delete_portal_path設置一些東西end' – ashvin

但是'destroy'動作已經在你的控制器中使用該方法使用'portal_path（portal），method :: delete'刪除對象，而不是'delete'的自定義路由。 – ashvin

您需要定義HTTP方法，當您使用刪除

= link_to 'Delete', portal_path(portal), method: :delete

它將工作。

您的link_to標籤有兩個問題。

您使用delete_portal_path(portal)但如果你的控制檯上運行rake routes你會看到沒有這樣的路徑存在。它有portal_path(portal)。
在Show（GET默認），update（PUT）和delete（DELETE）的情況下，您需要在路由中指定方法類型。因爲全部共享相同的路徑portal_path(portal)。

因此，最終的路線應該是：

= link_to 'Delete', portal_path(portal), method: :delete
