有没有人对Cocoa的选择性日志记录有任何好的想法？我一直试图想出一种简单的方法来一次打开和关闭一组类(比如我的服务类).但是,我想找出一种不会强迫我进入日志记录级别的方法.我环顾四周,似乎Cocoa没有好的日志框架,除了log4端口.任何想法,将不胜感激.

所以我试图获得一些基本的jQuery代码与Rails工作,但它似乎没有成功.我环顾四周,好像我正确地遵循了所有方向,并在多个浏览器中尝试过但无济于事.基本上,我只是试图在文件准备好上滑动div,但它只是停留在那里:(

<%= javascript_include_tag ['jquery-1.3.2', 'application'], :cache => true %>
<%= stylesheet_link_tag 'stylesheet' %>
<script type="text/javascript">
$(document).ready(function () {
    $('#login').hide("slide", { direction: "up"}, 5000);
});
</script>
<div id="container">
    <div id="left_nav">
        <p>Core Functions Will Go Here</p>
    </div>
    <div id="headertop"></div>
    <div id="logoheader">
        <%= link_to image_tag("vitaallogo.png"), root_path  %>      
    </div>
    <div id="user_nav">
        <% if current_user%>
            <%= link_to "Logout", logout_path %>
        <% else %>
            <%= link_to "Register", {:controller => 'user', :action => 'new'}%> |
            <%= link_to "Login", login_path %>
        <% end %>
    </div><br />
    <%= yield …

所以我只是尝试将我的第一个rails应用程序从我的笔记本电脑上的开发环境迁移到我的托管环境(只是另一台面向外部的机器),但我似乎一直在试图运行我的应用程序时遇到错误.

基本上我已经正确配置了apache和乘客,因为主站点仍然没有问题,但是当我尝试浏览运行rails应用程序的子目录时,我得到500错误说出错了.查看生产日志后,它表示没有数据
