#6 楼 @zhbinx 是的，还很简陋。谢谢意见！

#3 楼 @hbin 还好吧，是只狼，本来还想弄凶残一些的，但是可能不太容易被接受。

#1 楼 @loxeyer 是的 :D

ActionView::Template::Error (logo.png isn't precompiled):

我用rails g mongoid:config生成的config/mongoid.yml没有默认的生产环境配置。

2013/03/14 22:38:51 [error] 17086#0: *1 upstream prematurely closed connection while reading response header from upstream, client: 115.195.168.193, server: darkedog.com, request: "GET / HTTP/1.1", upstream: "passenger:unix:/passenger_helper_server:", host: "darkedog.com"
[ pid=17099 thr=69414950 file=utils.rb:176 time=2013-03-14 22:38:51.309 ]: *** Exception Mongoid::Errors::NoSessionsConfig in application (
Problem:
  No sessions configuration provided.
Summary:
  Mongoid's configuration requires that you provide details about each session that can be connected to, and requires in the sessions config at least 1 default session to exist.
Resolution:
  Double check your mongoid.yml to make sure that you have a top-level sessions key with at least 1 default session configuration for it. You can regenerate a new mongoid.yml for assistance via `rails g mongoid:config`.

 Example:
   development:
     sessions:
       default:
         database: mongoid_dev
         hosts:
           - localhost:27017

@caoxg 能否抄一部分你们的招聘内容？我会尽量借鉴的抄。

#3 楼 @happypeter #4 楼 @zz 看来还是继续买 VPS 了，我之前买了一个月的 linode。

#1 楼 @miclle 嗯，呵呵 谢谢！

前几天我也在西安遛了一下，感觉不错，现在在敦煌，过几天可能还回去西安待两天，玩！

#5 楼 @wujinlong 那我不知道了，我 google 翻了底朝天了就找到那两个方法。

只有 python 写的那个可以下载，但是 pull 都是 512x512 的图片，需要自己拼接。有时间，我可以把我自己的一些大图上传分享。

#1 楼 @jokry 谢谢 好了！ :)

#23 楼 @Rei 我是故意点击 topics/1 进来看看第一帖是啥，哈哈 这个海报真逗

#3 楼 @wujinlong 非常费劲，下载的原始图片都是经过 google 加密过被裁剪成 512 像素乘以 512 像素的小图片了，所以即使可以把所有的碎片都 pull 下来，但是还得花费相当大的功夫，用软件去拼接起来。

但是在 wiki 上有一部分比较高清的图片 (看你能否找到自己喜欢的了): https://commons.wikimedia.org/wiki/Category:Google_Art_Project

收藏了，谢谢！

#9 楼 @lidashuang 同样的问题

gem 'redcarpt', '~> 2.0' 

我版本换成这个就 ok 了。

#9 楼 @ghosTM55 确实 加油！

收藏了 谢谢！

太酷了！

#1 楼 @5long 谢谢

#7 楼 @Rei 呵呵

这么多种方式？

谢谢 哈哈！节日快乐！

我在 console 里面看到: [#<Photo id: 48, work_id: 0, created_at: "2012-09-27 11:34:28", updated_at: "2012-09-27 11:34:28", image: "brainhub.png">]

是没有关联上去。

works和photos的 controller 基本是一样的， `

def create
    @work = Work.new(params[:work])
    if @work.save
      redirect_to admin_category_path(@work.category), notice: "Successfully created."
    else
      render "new"
    end
  end

但是不知道为什么创建 works 的时候，正常。创建 photos 的时候就出错。

#1 楼 @chucai 我就是觉得那个 id 都多余， 想要这样的效果： http://huacnlee.com/blog/rails-app-image-store-with-carrierwave-upyun/

我感觉每次打开 railscasts 都特别慢，特别慢
