Heroku和Devise错误

Question

我刚刚将我的Devise更新为1.2,它在Heroku上给出了以下错误:

"Devise changed how it stores objects in session. If you are seeing this message, you can fix it by changing one character in your cookie secret or cleaning up your database sessions if you are using a db store."

如何清理我的heroku数据库中的数据库会话？

Answer 1

heroku rake db:sessions:clear 

将清空会话表
