Question

我一直在努力解决这个问题几个小时，我根本无法理解我应该如何做到这一点。我知道有几个人在同一主题或类似主题上写作，但它没有帮助。希望你能帮帮我。

我正在尝试在我正在进行的网站上建立一个投票系统，并且我正在使用它的宝石Thumbs_Up。它工作得很好，除了每次投票时都重新加载网站。

我的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

我的index.html.erb是这样的：

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

我正在尝试使用一些javascript，但它不起作用：

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

希望你能帮助一个菜鸟： - ）。

更新

视图的完整代码是：

<% @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 %>

这可能与编译错误有关？

忘记显示我的路线档案：

resources :images do
    member do
        post :vote_up
    end
end

Answer 1

如果您想发送AJAX请求，则必须在url helper中使用remote: true：

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

经过与纳什的长谈，我最终创建了一个新项目。一切都很乱。帮助纳什的谢谢。

呼叫投票方式，无需刷新页面。使用Thumbs_Up gem和Rails
