未初始化的常量 Authlogic::Session::Validation

Question

我正在将一个 rails 4.2 站点升级到 6.0 并且正在接收

uninitialized constant Authlogic::Session::Validation

当我尝试加载表单时，大概是因为验证模块已从 Authlogic 中删除，并且一些旧的 gem/code 仍在尝试引用它。如果我对 form_with 使用authentity_token=false 选项，它就会消失，但显然我不想这样做。

所以，不知何故，某处引用了这个旧模块。问题来了：

1. 我已经在整个代码库中搜索了 “Authlogic::Session::Validation”。什么都没有。
2. 我已经搜索了整个 “Authlogic::Session::Validation”的宝石树。什么都没有。

这就像它被配置为用于生成表单真实性令牌或其他东西的插件，但我不知道该配置在哪里或如何找到它。我的意思是，对于那个错误，那个字符串必须在某个地方，对吧？

这是我收到错误时调用堆栈的相关部分（我的代码在moments.haml 中）：

编辑：我在调用 form_authenticity_token （在上面的调用堆栈中引用）时设置 csrf-token 元标记时遇到了同样的错误。我忘记了我在尝试调试时已将其注释掉。

Answer 1

追踪到引用来自存储在我的用户会话数据中的错误。使用 rake:db:sessions:clear 清除了会话数据库，然后它就消失了。
