Question

我试图从Post模型创建API端点。它应该能够阅读，更新，删除和创建帖子。

但是帖子需要与主题相关联才能创建它，所以我将它嵌套在主题下。这是我的路线

namespace :api do
    namespace :v1 do
      resources :users, only: [:index, :show, :create, :update]
      resources :posts, only: [:show, :update, :destroy]
      resources :topics, except: [:edit, :new] do
        resources :posts, only: [:create]
      end
    end
  end 

       api_v1_post GET    /api/v1/posts/:id(.:format)                api/v1/posts#show
                   PATCH  /api/v1/posts/:id(.:format)                api/v1/posts#update
                   PUT    /api/v1/posts/:id(.:format)                api/v1/posts#update
                   DELETE /api/v1/posts/:id(.:format)                api/v1/posts#destroy
api_v1_topic_posts POST   /api/v1/topics/:topic_id/posts(.:format)   api/v1/posts#create
     api_v1_topics GET    /api/v1/topics(.:format)                   api/v1/topics#index
                   POST   /api/v1/topics(.:format)                   api/v1/topics#create
      api_v1_topic GET    /api/v1/topics/:id(.:format)               api/v1/topics#show
                   PATCH  /api/v1/topics/:id(.:format)               api/v1/topics#update
                   PUT    /api/v1/topics/:id(.:format)               api/v1/topics#update
                   DELETE /api/v1/topics/:id(.:format)               api/v1/topics#destroy

我的问题是我得到一个＆＃34;没有路线匹配＆＃34;我运行Rspec时出错

Answer 1

我认为问题在于关系。

请添加Topic和Post之间的关系，然后尝试。

class Topic < ActiveRecord::Base
    has_many :posts
end

class Post < ActiveRecord::Base
    belongs_to :topic
end

Answer 2

如果您尝试创建的路由POST api/v1/topics/:topic_id/create_post转到TopicsController而不是希望嵌套看起来像这样：

resources :topics, except: [:edit, :new] do
  post 'create_post' => 'topics#create_post'
end

Answer 3

如果您还没有成功，请尝试创建您的路线。它应该提供你想要的输出。

resources :topics, except: [:edit, :new] do
   collection do
      post 'create_post'
   end
end
