我正在将 rails 4.2 站点升级到 6.0 并收到
uninitialized constant Authlogic::Session::Validation
当我尝试加载表单时，大概是因为 Validation 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，在某个地方，某种东西正在引用这个旧模块。这是摩擦：
- 我已经在整个代码库中搜索“Authlogic::Session::Validation”。没有什么。
- 我已经在整个 gem 树中搜索“Authlogic::Session::Validation”。没有什么。
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。
