看到大家都说很厉害，可是翻墙都看不到，好想瞻仰下呀，求看到人把简历截个图回复下我、、、

#8 楼 @Eagle 还是没有解决呀。。。。

#4 楼 @Eagle 还有我使用的 gem 是”mongoid“而不是”mongo_mapper“会不会有影响呢？

#4 楼 @Eagle 我感觉还是数据库没有弄好，没有连上。。。才会造成的。。。。

#4 楼 @Eagle 代码里没有，我把完整的日志发给你看看：

#1 楼 @Eagle 新的错误：

ActionView::Template::Error (Could not connect to any secondary or primary nodes
 for replica set <Moped::Cluster nodes=[<Moped::Node resolved_address="127.0.0.1
:27017">]>):

好像是数据库连不上

#1 楼 @Eagle 你说的这些我都弄了，现在我又加了：

production:
  sessions:
    default:
      hosts:
        - localhost:27017
      database: spec_mongoid_development

但还是没有用，求帮忙呀。。。。

#19 楼 @chenge 谢谢你啦。。。。

#12 楼 @chenge 有 jquery.js 文件

#10 楼 @chenge 生成了，后面测试发现就是 Jquery 没有用，但是不知道到底为什么 Jquery 没用，在 application.html.erb 页面中的 head 中用下面的测试代码： `

$('#b').click(function(){ alert("hello"); });

` 结果页面没有反应。。

#7 楼 @chenge 看你的头像还以为是官方人士来解答问题啦。。。。

#7 楼 @chenge 哦哦哦。。。。嘿嘿！

#5 楼 @chenge 貌似网上说它很牛呀。。。。

#3 楼 @krazy 但是还是没找到原因，为什么 jquery 没有用，明明已经加载了 <script src="/assets/jquery.js?body=1" type="text/javascript"></script> 你知道有什么可能吗？

#1 楼 @krazy 刚才发现很奇怪的一件事，就是 JQuery 用不了，不知道是什么原因

#1 楼 @yanhao 使用是 jquery.html5-fileupload.js 插件，我的需求是要没选一张图片就上传一次，想 ruby-china 这个回复，右上角那个上传功能一样！

#10 楼 @Rei 不用麻烦了，我已找到了那个方法了。。。

#10 楼 @Rei 打扰你一下，https://github.com/ruby-china/ruby-china/blob/master/app/assets/javascripts/topics.coffee#L35 这一行的 fileUpload 方法是哪里来的呀？

#7 楼 @Rei 那如果要服务端解析它，我需要装些什么插件呢？

#3 楼 @Rei 上图，是这个链接，怎么才能变成

#3 楼 @Rei 还要请教下你，生成了“![](//l.ruby-china.com/photo/54cde5145470f896b346ae6c769baebe.jpg)” 并且把它添加到了正文中，但是在展示的时候，它是怎么变成“<image src='.............' />”？

#3 楼 @Rei 谢谢，谢谢！

#1 楼 @Tony612 谢谢你的回答，ruby-china 的源码对于我这个初学者还真有很大的难度呀。。。。

#16 楼 @leopku 试了下，还是一样哦。。。

#13 楼 @nightire 刚才在网上找了些答案，网上说有一个可能，是将 public key 复制到 github 时 public key 可能会增加了很多空格，导致公钥不正确，不知道是不是这个原因？

#11 楼 @nightire 这是反馈结果。。。。

#7 楼 @nightire 还有这张图 ，这是我按照它解决 Permission denied (publickey) 出现的问题。 打扰您啦，但是我真的需要解决。。。

#7 楼 @nightire 这是没有使用 passphrase 的情况。

#7 楼 @nightire 嗯嗯，我重新弄一次！我之前也试过没有 passphrase 的，但是也是同样的问题！

#3 楼 @nightire 这是我生成的 SHH 这个是我 github 上的 ssh-pub： 帮我看看是什么问题，谢谢您啦！
