问题描述：

Rails WEBrick 显示任何 ActiveRecord 活动的原始 SQL 语句.如何在控制台中启用它?

Rails WEBrick shows raw SQL statements for any ActiveRecord activities. How to enable that in the console?

答

要做到这一点，您必须启用记录器，您可以按如下方式执行此操作.

To do this you have to enable logger, you could do this as follows.

打开 rails 控制台:

Open the rails console:

ActiveRecord::Base.connection.instance_variable_set :@logger, Logger.new(STDOUT)
