嵌套路由问题："没有匹配的路由 [GET]"/问题/6/响应"

Question

我是一个rails初学者，有点纠结于路线。我正在一个Q& a网站(或问题和回应)工作，每当我试图发布回应时，它会给出以下错误:

No route matches [GET] "/questions/6/responses"

任何帮助都将非常感激。Jon

resources :users
resources :categories
resources :questions do
  resources :responses, :only => [:create]
end
root 'welcome#index'

Answer 1

您在ResponsesController中只有路由到create的动作。如果你还想路由到索引，你应该有:

resources :responses, only: [:create, :index]

如果你想路由到所有默认的资源动作，你应该放弃only选项，像这样:

resources :responses
