我正在将acts_as_votable整合到我的模型的元素中，而我几乎就在那里但是我遇到了一些缺少路线的问题。据我所知other question，在提升我的一个模型元素后，该应用程序将被重定向到：post。我试图包括资源：黑客和资源：黑客（已经存在）但似乎不是解决方案。
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
黑客秀
<p>
<strong>Liked by: </strong>
<%= @hack.liked_by @user %>
<%= link_to "Favorite?", like_hack_path(@hack), method: :put, class: "button tiny" %>
</p>

答案 0 :(得分：1)
您没有PostsController，根据我的意见，您想要更改此行：
put "like", to: "posts#upvote"
到
put "like", to: "hacks#upvote"
因为我认为您希望它指向HacksController，因为那是upvote操作的位置。
