after_create url_helpers不能在用戶模型中工作（與設計）

在after_create回調期間，url_helpers似乎不能在我的用戶模型中工作。以下是錯誤...after_create url_helpers不能在用戶模型中工作（與設計）

Url助手不能在AR模型中工作，完全停止，不需要回調。這是通過設計 - 您的模型層應該能夠在Web服務器的上下文之外運行。

您可以通過在該模型中的網絡堆棧的位捏造的問題，並有上，這樣會告訴你幾個問題在相關列表中的第一個爲這個問題怎麼..是：

Can Rails Routing Helpers (i.e. mymodel_path(model)) be Used in Models?

謝謝。經過更多的研究後，我認爲這個問題也源於Devise的使用。我已經爲我的問題添加了更多信息。 – 2011-01-20 20:27:41
