在我把Rails从SQLite迁移到SQL Server之前，我的设计工作得很好。迁移全部成功，并能够登录到Rails。但当我点击“注销”我得到下面的错误，

我不知道我该看什么或者看哪里。我是新手，所以简单的解释会很有帮助。谢谢

def forget_me!
return unless persisted?
self.remember_token = nil if respond_to?(:remember_token)
self.remember_me = nil if self.class.expire_all_remember_me_on_sign_out
#self.remember_created_at = nil if self.class.expire_all_remember_me_on_sign_out
save(validate: false)
end

我不确定迁移是否真的导致了这个问题，但我了解到model/user.rb中的 ：rememberable 选项负责创建时间和管理 remember_created_at。而且我在登录用户时没有记住我复选框。所以我完全删除了：可记住的选项。为了确保用户在一段时间后退出，包括 ：timeoutable 选项

您需要修改lib/devise/models/rememberable.rb中的forget_me函数。
删除或注解此行：

self.remember_created_at = nil if self.class.expire_all_remember_me_on_sign_out

并添加这一行：

self.remember_me = nil if self.class.expire_all_remember_me_on_sign_out

它应该看起来像这样：

def forget_me!
  return unless persisted?
  self.remember_token = nil if respond_to?(:remember_token)
  self.remember_me = nil if self.class.expire_all_remember_me_on_sign_out
  #self.remember_created_at = nil if self.class.expire_all_remember_me_on_sign_out
  save(validate: false)
end
