我有一个网址:
http://www.example.com/org/companyA
我希望能够使用正则表达式将CompanyA传递给视图.
这就是我所拥有的:
(r'^org/?P<company_name>\w+/$',"orgman.views.orgman")
它不匹配.
理想情况下,所有看起来像example.com/org/X的URL都会将x传递给视图.
提前致谢!
我不确定是什么改变了,但solr不能在我的机器上启动.我收到以下错误...

SELECT body, COUNT(body) AS dup_count
FROM comments
GROUP BY body
HAVING (COUNT(body) > 1)
并获取重复列表.看着这个我发现这些重复有多个哈希.评论的最短字符串是"[deleted]".所以让我们以此为例.在我的数据库中有九个评论实例,"[deleted]"在我的数据库中,这产生了1169143752200809218和1738115474508091027的散列.116次被发现6次,173次被发现3次.但是,当我在IRB中运行它时,我得到以下结果:
a = '[deleted]'.hash # => 811866697208321010
这是我用来生成哈希的代码:
def comment_and_hash(chunk)
comment = chunk.at_xpath('*/span[@class="comment"]').text ##Get Comment##
hash = comment.hash
return comment,hash
end
我已经确认我的代码中的任何其他位置都没有触及评论.这是我的datamapper类.
class Comment

有谁知道现在最好的方法吗？API不再受支持,我看到有人报告说他们无法获得无法使用的数据.宝石是帮助解决这个问题还是不解决？
提前致谢.
当我需要某些宝石时，它们中的一些会起作用，而另一些则不起作用。他们似乎安装了 find ，我可以做一个 gem 列表，他们就在那里。但是，当我尝试在 Irb 中运行它们或从终端运行我的 ruby 程序时，我得到以下信息：
LoadError: no such file to load -- sanitize
/Library/Ruby/Site/1.8/rubygems/custom_require.rb:54:in `gem_original_require'
所以我遵循了 RubyGems 的指南，一切似乎都很好：
noahclark$ gem list sanitize
*** LOCAL GEMS ***
sanitize (2.0.3)
noahclark$ ruby -rubygems -e 'require "sanitize"'
noahclark$
noahclark$ which ruby
/opt/local/bin/ruby
noahclark$ gem env | grep 'RUBY EXECUTABLE'
- RUBY EXECUTABLE: /opt/local/bin/ruby
然后我尝试了：
noahclark$ which gem
/opt/local/bin/gem
noahclark$ gem environment
RubyGems Environment:
- RUBYGEMS VERSION: 1.8.10
- RUBY VERSION: 1.8.7 (2011-06-30 patchlevel 352) [i686-darwin10]
- INSTALLATION DIRECTORY: /opt/local/lib/ruby/gems/1.8 …假设我有类似的东西
true && true #=> true
这是有道理的,所以我尝试类似的东西:
true && "dsfdsf" #=> "dsfdsf"
这让我感到惊讶,因为我经常会做类似的事情,if something && something而且我一直认为那是评估为真,并且会回归真实.进一步的实验做的事情如下:
jruby-1.7.3 :009 > "ad" && "dsf"
=> "dsf"
jruby-1.7.3 :010 > "ad" && "sdfd" && nil
=> nil
jruby-1.7.3 :011 > "ad" && nil && "sdf"
=> nil
如果全部为真,或者它找到的第一个假值,Ruby似乎返回最后一个值.为什么这样做？这是一个正确的心理模型吗？
我试图让我的元描述在HAML中工作,我尝试的一切都会产生错误.
%meta{:name => "description", :content => "Some content"}/
%title
= data.page.title
上面的代码有效.现在我尝试以下方法:
%meta{:name => "description", :content =>
= data.page.desc
}/
%title
= data.page.title
我在第一行得到不平衡的括号错误.我究竟做错了什么？
我有一堆域名,例如store.example.com,user.example.com,intranet.example.com,每个域都可以读取cookie.但是,我有一个Sinatra应用程序通过做类似的事情来编写cookiesession[:field] = value
当我检查cookie时,我得到这样的东西:BAh7CUkiD3Nlc3Npb25faWQGOgZFVEkiRTcwNmUwYTU1MjBmMzUyMTZiYzQ0%0ANjZhZDBkOGFmNmFhN2M3OGIxZTM3NGNjMDZiYmRkNDE2MmVlMDU2MWY2MTQG%0AOwBGSSIJY3NyZgY7AEZJIiVkMWUyYzI0NmEwZThiNjVhM2FlZGJjNWFhMzlk%0AYzc0YQY7AEZJIg10cmFja2luZwY7AEZ7B0kiFEhUVFBfVVNFUl9BR0VOVAY7%0AAFRJIi0xZDQ3MmI3NDZiMjFhNmJlNmYyMmUxMGU1MzI3N2Q5MmVlYmQ1N2Qx%0ABjsARkkiGUhUVFBfQUNDRVBUX0xBTkdVQUdFBjsAVEkiLTY2ZWFlOTcxNDky%0AOTM4YzJkY2MyZmIxZGRjOGQ3ZWMzMTk2MDM3ZGEGOwBGSSIQdXNlcl9zZWNy%0AZXQGOwBGSSIlMjg3NjdkMGVmNmZlOGUwMDIxMDRmODhiZDcwZTI1OTYGOwBU%0A--e8ca14be9bbe63226fd2d6e0f8c0b3946cc66fd0它似乎是base64编码和加密的.
我的问题是如何编写一个"原始"cookie,所有可以通过尝试使用它的子域都可以轻松阅读？它不需要加密和/或编码.
