Rails Puma Server：注销操作时未定义“extract_multipart”或“before_create”

Question

我无法退出自己的页面，因为每次尝试都会收到undefined method Puma 错误。大多数时候是extract_multipart，但我也见过before_create。

当我单击注销时，这就是空白页面中显示的内容

Puma caught this error: undefined method `extract_multipart' for Rack::Multipart:Module (NoMethodError)
/var/lib/gems/2.3.0/gems/rack-2.0.1/lib/rack/request.rb:472:in `parse_multipart'

我管理注销的方式是使用

<%= link_to(logout_path, method: 'delete', class: 'dropdown-item') do %>
<!-- ... -->
<% end %>

其中路由定义为delete 'logout' => 'sessions#destroy'，控制器/动作为

def destroy
  session[:id] = nil
  redirect_to '/login'
end

另一个我只发现一两次的错误，我只有一个截图

Puma: undefined before_create

关于可能导致此问题的任何想法？提前感谢:)

编辑

根据要求，这里是 Enumerable 关注点，我实际上并没有使用它，因为我也遇到了这个问题（在 auto-inc 存储库上提交的 GH 问题）

require 'autoinc'

module Enumerable
  extend ActiveSupport::Concern

  included do
    include Mongoid::Autoinc
    include Mongoid::Document

    field :n, as: :number, type: Integer

    increments :number
  end
end

而我使用的唯一before_create 在一个完全不相关的模块中...

尝试将 puma 更新为 3.7.0，但没有解决。虽然它并没有进一步打破它......
