问题描述

I am using Rails 4 and MongoDB as a database for my project. 我将Rails 4和MongoDB用作项目的数据库。 I'm using the "devise" gem for creating logins, but I am not able to find a version of MongoMapper compatible with Rails 4. I'm getting the following error: 我正在使用“ devise” gem创建登录名，但找不到与Rails 4兼容的MongoMapper版本。出现以下错误：

The latest versions of devise seem to only have ORM support for mongoid and active record. devise的最新版本似乎仅对蒙古语和活动记录提供ORM支持。

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

There are some gems around which might help, but they are out of date and probably will not work with the latest devise/mongomapper. 周围有一些宝石可能会有所帮助，但是它们已经过时，可能无法与最新的devise / mongomapper一起使用。

If you have to use mongodb, then use the mongoid driver (instead of mongomapper), which is supported. 如果必须使用mongodb，请使用受支持的Mongoid驱动程序（而不是mongomapper）。
