调用投票方法，无需刷新页面。使用Thumbs_Up宝石和Rails

Question

我一直在为此挣扎几个小时，而我根本无法过去我应该如何去做。我知道有几个人写同一主题或类似的东西，但没有帮助。希望您能够帮助我。

我正在尝试在我正在做的网站上制作投票系统，并且我正在为它配置gem Thumbs_Up。它工作正常，除了每次投票时重新加载站点。

我images_controller.rb是这样的：

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

我index.html.erb是这样的：

<%= link_to('vote for this post!', vote_up_image_path(image)) %> 

我正与一些JavaScript很努力，但它不工作：

$(".shotBG a").click(function(){ 
    $.ajax({ 
     type: 'PUT', 
     url: "http://localhost:3000/images/37/vote_up", 
     success: function(){ 
      alert("hello"); 
     } 
    }); 
    return false; 
}); 

希望你能帮助noob out :-)。

UPDATE

的查看完整的代码是：

<% @images.each do |image| %> 
    <li class="shotBG bottomShots"> 
     <img class="shot" src="<%= image.uploaded_file.url %>" alt="Competing for dribbble invites." /> 
     <%= link_to('vote for this post!', vote_up_image_path(image)), :remote => true, :method => :post %> 
    </li> 
<% end %> 

这可能有一些做的编译错误？

更新2

忘记展示我的路由文件：

resources :images do 
    member do 
     post :vote_up 
    end 
end

经过与纳什的长谈，我最终创建了一个新项目。一切都很混乱。谢谢你的帮助纳什。

如果您想发送一个AJAX请求，您必须使用remote: true在网址帮手：

<%= link_to('vote for this post!', vote_up_image_path(image), :remote => true, :method => :post) %>
