Question

是否可以在没有用户登录的情况下使用thumbs_up gem？基本上，我希望任何人都可以在不必登录的情况下投票，例如http://www.yourather.com。

最后，当我尝试对评论进行投票时收到路由错误消息，在投票时发生同样的事情。

No route matches [GET] "/comments/1/vote_up"

型号：

class Comment < ActiveRecord::Base
  acts_as_voteable
end

class Article < ActiveRecord::Base
  acts_as_voteable
end

查看：

<%= link_to image_tag("up_arrow.jpeg"), vote_up_comment_path(@comment), 
    :method => 'post' %></br>
<%= link_to image_tag("down_arrow.jpeg"), vote_down_comment_path(@comment), 
    :method => 'post' %></br>

控制器：

def vote_up
  begin
    vote_for(@comment = Comment.find(params[:id]))
    render :nothing => true, :status => 200
  rescue ActiveRecord::RecordInvalid
    render :nothing => true, :status => 404
  end
end

def vote_down
  begin
    vote_against(@comment = Comment.find(params[:id]))
    render :nothing => true, :status => 200
  rescue ActiveRecord::RecordInvalid
    render :nothing => true, :status => 404
  end
end

Routes.rb：

resources :comments do
  member do
    post :vote_up
    post :vote_down
  end
end

resources :articles do
  member do
    post :vote_up
    post :vote_down
  end
end

Rake Routes（相关部分）：

                          /comment/:id(.:format)               comments#show
                          /article/:id(.:format)               articles#show

我查看了Clarification on how to use "thumbs_up" voting gem with Rails 3和其他相关问题，但我无法使其发挥作用。感谢

docs on link_to表示：method选项应该是一个符号。尝试更改视图：

<%= link_to image_tag("up_arrow.jpeg"), vote_up_comment_path(@comment), 
:method => 'post' %></br>

到

<%= link_to image_tag("up_arrow.jpeg"), vote_up_comment_path(@comment), 
:method => :post %></br>

rails voting gem，thumbs_up，没有用户。还有，路由错误
