未初始化的常量PostsController - 集成充當可用

Question

我正在將acts_as_votable集成到我的模型的元素中，而且我幾乎在那裏，但是我面臨着一些缺少路由的問題。就我所瞭解的other question而言，在對我的Model元素中的一個加註後，該應用程序將被重定向到：post。我試圖包括資源：黑客和資源：黑客（已經存在），但它似乎不是解決方案。

的routes.rb

 Rails.application.routes.draw do 
     resources :hacks do 
      member do 
      put "like", to: "posts#upvote" 
      end 
     end 

     devise_for :users, :controllers => { omniauth_callbacks: 'omniauth_callbacks' } 
     match '/profile/:id/finish_signup' => 'users#finish_signup', via: [:get, :patch], :as => :finish_signup 

     match 'tagged' => 'hacks#tagged', :as => 'tagged', via: 'get' 
     #To show public profiles 
     get '/users/:id', :to => "users#show", :as => :user 

     root "pages#home" 

     get 'pages/about' 

     # TheComments routes 
     concern :user_comments, TheComments::UserRoutes.new 
     concern :admin_comments, TheComments::AdminRoutes.new 
     resources :comments, concerns: [:user_comments, :admin_comments] 

     end 

劈顯示

  <p> 
       <strong>Liked by: </strong> 
      <%= @hack.liked_by @user %> 
      <%= link_to "Favorite?", like_hack_path(@hack), method: :put, class: "button tiny" %> 

      </p>

Answer 1

你沒有PostsController，並從我所看到的，要改變這一行：因爲我相信你

put "like", to: "posts#upvote" 

到

put "like", to: "hacks#upvote" 

希望它指向HacksController，因爲這是upvote操作的位置。
