导轨路由错误
问题描述：
奇怪的错误。我是rails的新手。从一个新的安装导轨我连接到Oracle数据库，然后跑：导轨路由错误
jruby script/generate scaffold job oid:integer userid:integer name:string status:integer
没有做别的事情，我开始了服务器，并进入了一个新的工作，然后我得到这个错误：
Routing Error
job_url failed to generate from {:controller=>"jobs", :action=>"show", :id=>#<Job id: #<BigDecimal:d55a0f,'10000.0',1(8)>, oid: #<BigDecimal:10bb83e,'1324.0',4(8)>, userid: #<BigDecimal:6d234c,'1234.0',4(8)>, name: "asdfadsf", status: #<BigDecimal:1286c71,'1234.0',4(8)>, created_at: "2009-12-15 00:49:37", updated_at: "2009-12-15 00:49:37">}, expected: {:controller=>"jobs", :action=>"show"}, diff: {:id=>#<Job id: #<BigDecimal:853e51,'10000.0',1(8)>, oid: #<BigDecimal:1be4050,'1324.0',4(8)>, userid: #<BigDecimal:adb165,'1234.0',4(8)>, name: "asdfadsf", status: #<BigDecimal:15978e7,'1234.0',4(8)>, created_at: "2009-12-15 00:49:37", updated_at: "2009-12-15 00:49:37">}
即使它抛出错误，它仍然创建记录。当我尝试查看记录时，我得到以下堆栈，这实际上是相同的错误。

当我删除了“edit_job_path”方法错误消失，所以我知道它只是有一个问题渲染路线，但我不知道为什么，因为它似乎有正确的信息。我的意思是这是一个样板脚手架，所以....在此先感谢您的帮助！
答
这是因为您的ID字段是BigDecimal，它应该是Integer。它将一个数字如“1234.54”分成两部分，如{:action => "1234", :format => "54" }。
答
请确保您有这条线在你的config/routes.rb文件：
map.resources :jobs
，也需要运行“耙路”，看看哪条路线可供选择。 * path和* url方法由您在routes.rb文件中定义的命名路由和资源生成。更多信息here。
宾果。谢谢瑞恩！我意识到在发布BigDecimal后发生了一些事情，但并不确定是什么。你钉了它。这是因为我使用的是JRuby，我不需要这么做，因此我将切换回非Java Java虚拟机。 – 2009-12-16 16:23:07
