Question

我已经安装了acts_as_votable宝石，我正在尝试实现两个按钮，一个用于喜欢一个引脚，另一个用于取消引脚。我已经设法创建一个像针一样的按钮，这是有效的。但是，当我现在尝试添加第二个按钮时，我会卡住。任何帮助非常感谢!!

我的图钉索引视图

<div class="actions">
   <% if user.likes? @pin%>
       <%= link_to unlike_pin_path(pin), method: :put, remote: true, class: "btn btn-default" do %>
       <span class="glyphicon glyphicon-heart"></span>
       <% end %>
   <% else %>
      <%= link_to like_pin_path(pin), method: :put, remote: true, class: "btn btn-default" do %>
      <span class="glyphicon glyphicon-heart-empty"></span>I like
      <% end %>
   <% end %>
</div>

我的引脚控制器：

def like
  @pin.liked_by current_user
  redirect_to :back
end

def unlike
  @pin.unliked_by current_user
  redirect_to :back
end

Answer 1

acts_as_votable gem不提供likes?方法。它确实提供了liked?方法。没有经过测试我想你想使用以下代码：

<div class="actions">
  <% if user.liked? @pin %>
   <%= link_to unlike_pin_path(pin), method: :put, remote: true, class: "btn btn-default" do %>
    <span class="glyphicon glyphicon-heart"></span>
  <% end %>
  <% else %>
  <%= link_to like_pin_path(pin), method: :put, remote: true, class: "btn btn-default" do %>
    <span class="glyphicon glyphicon-heart-empty"></span>I like
  <% end %>
  <% end %>
</div>

Answer 2

对于unlike_pin_path，请确保您的routes.rb文件包含以下内容：

resources :pins do
  member do
    put "like", to: "pins#upvote"
    put "unlike", to: "pins#downvote"
  end
end

带有acts_as_votable gem的Second Like / Different按钮
