導軌路由錯誤

Question

奇怪的錯誤。我是rails的新手。從一個新的安裝導軌我連接到Oracle數據庫，然後跑：

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

沒有做別的事情，我開始了服務器，並進入了一個新的工作，然後我得到這個錯誤：

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">} 

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

當我刪除了「edit_job_path」方法錯誤消失，所以我知道它只是有一個問題渲染路線，但我不知道爲什麼，因爲它似乎有正確的信息。我的意思是這是一個樣板腳手架，所以....在此先感謝您的幫助！

Answer 1

這是因爲您的ID字段是BigDecimal，它應該是Integer。它將一個數字如「1234.54」分成兩部分，如{:action => "1234", :format => "54" }。

Answer 2

請確保您有這條線在你的config/routes.rb文件：

map.resources :jobs 

，也需要運行「耙路」，看看哪條路線可供選擇。 * path和* url方法由您在routes.rb文件中定義的命名路由和資源生成。更多信息here。
