我正在使用devise gem与Ruby on Rails webapp，并在本教程之后介绍如何在用户登录后将用户重定向到之前的页面，登出。问题是，代码似乎适用于登录部分，但注销总是将用户重定向到root_path。
I am using the devise gem with a Ruby on Rails webapp and following this tutorial on how to redirect the user back to their previous page after they login and logout. The problem is, that the code seems to work for the login part, but logout always redirects the user to the root_path.
当我完全遵循教程，重定向工作在一个，我错过了一个打字错误，还是在其他代码覆盖这个代码？
As I followed the tutorial exactly, and the redirect works for one, have I missed a typo or is there code elsewhere that is overwriting this code?

提前谢谢您的帮助。
推荐答案我相信您的会话变量在注销时被设置为nil，因此重定向到根路径。
I believe your session variable is being set to nil on logout, hence the redirect to the root path.
尝试以下设置保持会话范围与退出无关。
Try the below setting to the keep session scope irrelevant to logout.
config.sign_out_all_scopes = false在devise.rb文件中获取所需的行为
in the devise.rb file to get the desired behaviour
