Question

我在 Rails 项目的 Ruby 中使用 acts_as_votable gem 喜欢和不喜欢 "Deals"。我的用户设置为 act_as_voter，我的交易设置为 acts_as_votable，但出于某种原因，一旦创建新用户，一切都设置为喜欢，并且他们无法取消交易。出于某种原因，我的交易列表都有一个不同的按钮，它实际上除了刷新页面之外什么也没做。这是我的一些代码。

app/views/catalog/index.html.erb

<ul class="deals_list">
  <% @deals.each do |deal| %>
    <li>
      <div>
        ...
      <div class="favorite">
        <% if account_signed_in? and current_account.accountable_type == "Personnel" %>
          <%= image_tag("dark-favorite.png") %>
          <% if deal.liked_by current_account %>
            <%= link_to unlike_deal_path(deal), method: :put do %>
              Unlike
            <% end %>
          <% else %>
            <%= link_to like_deal_path(deal), method: :put do %>
              Like
            <% end %>
          <% end %>
        <% end %>
      </div>
    </li>
  <% end %>
</ul>

app/controllers/deals_controller.rb

def like
    @deal = Deal.find(params[:id])
    @deal.liked_by current_account
    redirect_back(fallback_location: catalog_index_url)
  end

  def unlike
    @deal = Deal.find(params[:id])
    @deal.unliked_by current_account
    redirect_back(fallback_location: catalog_index_url)
  end

config/routes.rb

resources :deals do
    member do
      put 'like', to: "deals#like"
      put 'unlike', to: "deals#unlike"
    end
  end

请务必阅读整个自述文件，因为您使用的库有误。

To check if a voter has voted on a model, you can use voted_for?. You can check how the voter voted by using voted_as_when_voted_for.

我关注你的问题是因为我期待看到一个“？”在 deal.liked_by 调用之后，这将指示布尔结果（按照惯例，并非总是如此）。

所以改用这个：

<% if current_account.voted_for? deal %>
