和我的路由文件：

Rails.application.routes.draw do
resources :sessions, only: [:new, :create, :destroy]
 resources :users
  match '/new_game',  to: 'games#new',            via: 'get'
  match '/signup',  to: 'users#new',            via: 'get'
  match '/signin',  to: 'sessions#new',         via: 'get'
  match '/signout', to: 'sessions#destroy',     via: 'delete'

  # The priority is based upon order of creation: first created -> highest priority.
  # See how all your routes lay out with "rake routes".

  # You can have the root of your site routed with "root"
  root 'home#home'

  # Example of regular route:
  #   get 'products/:id' => 'catalog#view'

  # Example of named route that can be invoked with purchase_url(id: product.id)
  #   get 'products/:id/purchase' => 'catalog#purchase', as: :purchase

  # Example resource route (maps HTTP verbs to controller actions automatically):
  #   resources :products

  # Example resource route with options:
  #   resources :products do
  #     member do
  #       get 'short'
  #       post 'toggle'
  #     end
  #
  #     collection do
  #       get 'sold'
  #     end
  #   end

  # Example resource route with sub-resources:
  #   resources :products do
  #     resources :comments, :sales
  #     resource :seller
  #   end

  # Example resource route with more complex sub-resources:
  #   resources :products do
  #     resources :comments
  #     resources :sales do
  #       get 'recent', on: :collection
  #     end
  #   end

  # Example resource route with concerns:
  #   concern :toggleable do
  #     post 'toggle'
  #   end
  #   resources :posts, concerns: :toggleable
  #   resources :photos, concerns: :toggleable

  # Example resource route within a namespace:
  #   namespace :admin do
  #     # Directs /admin/products/* to Admin::ProductsController
  #     # (app/controllers/admin/products_controller.rb)
  #     resources :products
  #   end
end

我真的很感激所有的帮助。如果有任何更多的信息，我可以提供，请这样说

谢谢您

您会发现，当您在控制台中执行
bundle exec rake routes
时，您实际上并没有为游戏路径创建命名路由

如果您正在使用
match
并想命名一条路线（因此您有类似
games\u path
的东西可用），您必须执行以下操作：

match `/games`, as: 'games', to: 'games#index', via: :get
一种更简单的方法是为大多数路由使用资源，只需使用默认的RESTFUL路径：

resources :games

# Now you have access to '/games/new', '/games/:id',
# '/games', etc, as well as names such as `games_path`.
# Check `bundle exec rake routes` for all of them.
有关更多信息，请参阅

最好的选择是在
routes.rb

resources :games
并通过“获取”路径将
match'/new#game'删除到：“games#new”

这样做将为您提供以下Restful路线：


Prefix        Verb   URI Pattern                          Controller#Action
games         GET    /games(.:format)                     games#index
              POST   /games(.:format)                     games#create
new_game      GET    /games/new(.:format)                 games#new
edit_game     GET    /games/:id/edit(.:format)            games#edit
game          GET    /games/:id(.:format)                 games#show
              PATCH  /games/:id(.:format)                 games#update
              PUT    /games/:id(.:format)                 games#update
              DELETE /games/:id(.:format)                 games#destroy


因此，在提交表单时，您的应用程序将通过HTTP Post请求路由到
创建
操作（
游戏路径
）

目前，您刚刚为
游戏
资源定义了一条路线，该路线通过


match '/new_game',  to: 'games#new',            via: 'get'


但是没有
创建
操作的路径，这就是为什么您在表单上收到错误为
未定义的方法“games\u path”

如果您不希望使用RESTful路由（
resources:games
），则必须将路由定义为：


match '/games', as: 'games', to: 'games#create', via: 'post'



对于
创建
操作。
rout helper错误后的标准第一步是rake routes，以查看您从路由配置中真正获得的帮助。非常感谢。我觉得自己像个白痴。我想我只是忘了将它声明为资源。再次感谢您的帮助。如果您发现我的答案解决了您的问题，请随意接受；）
