我遇到以下問題。嘗試爲ActionMailer呈現模板時，我的Resque後臺作業失敗。但是這隻有在我處於生產環境時纔會發生。爲什麼Rails ActionMailer會在生產環境中引發路由錯誤？
錯誤與路由錯誤有關。這裏是堆棧跟蹤：

在我的視圖模板的代碼如下：
link_to _("Click here to see the case"),
account_case_url(:only_path => false,
:host => "production.foo.com",
:controller => "cases",
:action => "show",
:id => @case.id, :account_id => @case.account.id)
我知道有一個similar post on SO，但答案是沒有給出。另外，我不得不再次說，我的問題只出現在生產環境中。我不得不再次說這與resque無關。禁用重新發送郵件後，我可以複製該問題。因此，生產中的ActionMailer會導致此問題。
UPDATE 2問題似乎出現在Rails 3.0.11和3.0.12上。 3.0.10工作正常。
這是堆棧跟蹤，但它的實際錯誤信息是什麼？ – 2012-03-12 16:02:53
