如何在使用rails 4版本的mongodb中使用「設計」gem？

Question

我正在使用Rails 4和MongoDB作爲我的項目的數據庫。我使用了「制定」創業板創建登錄，但我無法找到使用Rails 4.我收到以下錯誤兼容的版本MongoMapper的：

如何使用MongoMapper與Rails 4？

Answer 1

devise的最新版本似乎只有ORM支持mongoid和活動記錄。

https://github.com/plataformatec/devise/tree/master/lib/devise/orm

大約有可能幫助一些寶石，但他們是過時的，可能不會有最新色器件/ mongomapper工作。

如果您必須使用mongodb，那麼請使用支持的mongoid驅動程序（而不是mongomapper）。
