Question

我有房型，我想为facebook创建一个分享按钮。所以我决定用sharer url方法做到这一点。我想在show.html.erb（房间视图）上有一个facebook图标，用户或访问者可以在Facebook上共享房间。当我点击链接时，我被重定向到Facebook，我必须手动输入链接，而不是自动输入我要分享的链接。如果我要将show.html.erb link_to更新为：

<%= link_to image_tag('facebook_icon_red.png'), 'http://www.facebook.com/sharer.php?u=<%= yield :url %>', :target => :blank %>

然后我收到错误：

我该如何使用？

application.html.erb

<!DOCTYPE html>
<html>
  <head>
...
...
    <!-- for Facebook -->          
    <meta property="og:title" content="<%= @room.listing_name %>" />
    <meta property="og:type" content="room" />
    <meta property="og:image" content="" />
    <meta property="og:url" content="<%= room_url(@room) %>" />
    <meta property="og:description" content="<%= @room.detailed_description %>" />
  </head>

<body>
    <!-- Facebook Sharing Settings-->
    <div id="fb-root">
    </div>
    <script src="http://connect.facebook.net/en_US/all.js" type="text/javascript"></script>
    <script type="text/javascript">
    FB.init({
        appId: MY_ID(SOME NUMBERS),
        status: true,
        cookie: true,
        xfbml: true
    });
    FB.Canvas.setAutoResize();
    </script>

你的link_to就像这样：

<%= link_to image_tag('facebook_icon_red.png'), "http://www.facebook.com/sharer.php?u=#{yield :url }", :target => :blank %>

这应该适合你。
