Rails路由錯誤

Question

奇怪的錯誤。 我是護欄的新手。 從新安裝的rails中，我連接到oracle db，然后運行：

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

沒有做任何其他事情，我啟動了服務器並輸入了新作業，然后出現此錯誤：

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">}

即使拋出錯誤，它仍然會創建記錄。 當我嘗試查看記錄時，得到以下堆棧，這實際上是相同的錯誤。

當我刪除“ edit_job_path”方法時，錯誤消失了，所以我知道它在呈現路線時存在問題，但是我不確定為什么，因為它似乎具有正確的信息。 我的意思是，這是一個樣板支架，....在此先感謝您的幫助！

Answer 1

這是因為您的ID字段是BigDecimal ，應該是Integer 。 它正在解釋一個數字，例如將“ 1234.54”分為兩部分，例如{:action => "1234", :format => "54" } 。

Answer 2

確保您的config / routes.rb中包含以下行：

map.resources :jobs

另外，運行“ rake route”以查看可用的路由。 * path和* url方法是由在route.rb文件中定義的命名路由和資源生成的。 更多信息在這里 。
