Question

我的应用程序上有投票功能，但无法通过投票返回同一页面。我知道我必须填写link_to方法，但我对路由/ ruby语法的理解有点受限，所以我甚至不确定[post，vote]是否正确。我觉得我也错过了其他的东西。我甚至提供了足够的信息吗？我该如何处理这个问题？或者更好的是，我怎样才能更好地理解路由？谢谢。

以下是我得到的错误： No route matches [GET] "/posts/13/up-vote"

我的投票部分：

<% if policy( Vote.new ).create? %>
  <div class="vote-arrows pull-left">
    <div>
      <%= link_to [post, vote],
        post_up_vote_path(post),
        class: "glyphicon glyphicon-chevron-up #{(current_user.voted(post) && current_user.voted(post).up_vote?) ? 'voted' : '' }" %>
    </div>
    <div>
      <strong><%= post.points %></strong>
    </div>
    <div>
      <%= link_to [post, vote],
        post_down_vote_path(post),
        class: "glyphicon glyphicon-chevron-down #{(current_user.voted(post) && current_user.voted(post).down_vote?) ? 'voted' : '' }" %>
    </div>
  </div>
<% end %>

my routes.rb

   Bloccit::Application.routes.draw do

      devise_for :users
      resources :users, only: [:update]

      resources :topics do
        resources :posts, except: [:index]
      end

      resources :posts, only: [] do
        resources :comments, only: [:create, :destroy]
        resources :favorites, only: [:create, :destroy]
        post '/up-vote' => 'votes#up_vote', as: :up_vote
        post '/down-vote' => 'votes#down_vote', as: :down_vote
      end

      get 'about' => 'welcome#about'

      root to: 'welcome#index'
end

查看错误消息：No route matches [GET] "/posts/13/up-vote"。它正在寻找[GET]路由，但您已在[POST]文件中定义了config/routes.rb路由。

您需要向method: :post个link_to个助手添加[POST]才能触发<%= link_to [post, vote], post_down_vote_path(post), class: "glyphicon glyphicon-chevron-down #{(current_user.voted(post) && current_user.voted(post).down_vote?) ? 'voted' : '' }", method: :post %>个请求。这就是它的样子：
