Rails路由错误

Question

奇怪的错误。 我是护栏的新手。 从新安装的rails中，我连接到oracle db，然后运行：

jruby script/generate scaffold job oid:integer userid:integer name:string status:integer

没有做任何其他事情，我启动了服务器并输入了新作业，然后出现此错误：

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">}

即使抛出错误，它仍然会创建记录。 当我尝试查看记录时，得到以下堆栈，这实际上是相同的错误。

当我删除“ edit_job_path”方法时，错误消失了，所以我知道它在呈现路线时存在问题，但是我不确定为什么，因为它似乎具有正确的信息。 我的意思是，这是一个样板支架，....在此先感谢您的帮助！

Answer 1

这是因为您的ID字段是BigDecimal ，应该是Integer 。 它正在解释一个数字，例如将“ 1234.54”分为两部分，例如{:action => "1234", :format => "54" } 。

Answer 2

确保您的config / routes.rb中包含以下行：

map.resources :jobs

另外，运行“ rake route”以查看可用的路由。 * path和* url方法是由在route.rb文件中定义的命名路由和资源生成的。 更多信息在这里 。
