Based on this the answer is simple. In your config/initializers/mongo.rb file change your connection string as follows:
基于此，答案很简单。在config / initializers / mongo.rb文件中，更改连接字符串，如下所示：
logger = Logger.new(STDOUT)
MongoMapper.connection = Mongo::Connection.new('mongo.example.com', 27017, :logger => logger)
Restart Rails and the Mongo query strings now show up in the logger.
重新启动Rails，Mongo查询字符串现在显示在记录器中。
