if something_is_not_kosher
  # 1. log this event,2. send notice
  redirect_to destroy_user_session_path and return
end

还尝试过：

if something_is_not_kosher
 # 1. log this event,2. send notice
  redirect_to controller: 'devise/sessions',action: 'destroy',method: :delete and return
end

错误是没有路由匹配[GET]“/ users / sign_out”但我明确设置方法::在示例2中删除.也许设计有一个方法？ current_user.sign_out并试过sign_out(current_user)哪个也行不通？谢谢您的帮助.

耙路线：

            user_session POST   /users/sign_in(.:format)         devise/sessions#create
    destroy_user_session DELETE /users/sign_out(.:format)        devise/sessions#destroy
