Rails 6 Zeitwerk "DEPRECATION WARNING: Initialization autoloaded the constants..." 但我不知道在哪里？
Rails 6 Zeitwerk "DEPRECATION WARNING: Initialization autoloaded the constants..." but I can't figure out where?
我发誓我已经阅读了文档并且我认为我对这些原则有基本的了解，但是我终究无法弄清楚我在哪里不恰当地加载了这些常量。
我正在努力升级最初是 Rails 5.2
的应用程序
我在 运行 RSpec、服务器、本地控制台等时收到此警告
DEPRECATION WARNING: Initialization autoloaded the constants ApplicationHelper, EventsHelper, FontAwesome::Rails::IconHelper, DeviseHelper, ErrorHandler, and ApplicationController.
Being able to do this is deprecated. Autoloading during initialization is going
to be an error condition in future versions of Rails.
以下是不恰当地自动加载的常量：
- ApplicationHelper - 标准 Rails 文件
- EventsHelper - EventsController
的标准 Rails 文件
- FontAwesome::Rails::IconHelper - 来自 gem，不在我的应用程序目录中
- DeviseHelper - 来自 gem，不在我的应用程序目录中
- ErrorHandler - 位于 'app/controllers/concerns/error_handler'
- ApplicationController - 标准 Rails 文件
我寻找了可能为这些常量调用 include 或 require 的实例，但找到了 none。我特别关注我的初始化器。
我 运行（并通读）bin/rails zeitwerk:check，没有任何明显的提示。我看到这些实例按预期加载：
...
Zeitwerk@rails.main: constant ApplicationHelper loaded from file /Users/ckragt/ruby/filterbuildscheduler/app/helpers/application_helper.rb
...
Zeitwerk@rails.main: constant EventsHelper loaded from file /Users/ckragt/ruby/filterbuildscheduler/app/helpers/events_helper.rb
...
Zeitwerk@rails.main: constant FontAwesome::Rails::IconHelper loaded from file /Users/ckragt/.rvm/gems/ruby-2.7.0/gems/font-awesome-rails-4.7.0.7/app/helpers/font_awesome/rails/icon_helper.rb
...
Zeitwerk@rails.main: constant DeviseHelper loaded from file /Users/ckragt/.rvm/gems/ruby-2.7.0/gems/devise-4.7.3/app/helpers/devise_helper.rb
...
Zeitwerk@rails.main: constant ErrorHandler loaded from file /Users/ckragt/ruby/filterbuildscheduler/app/controllers/concerns/error_handler.rb
...
Zeitwerk@rails.main: autoload set for ApplicationController, to be loaded from /Users/ckragt/ruby/filterbuildscheduler/app/controllers/application_controller.rb
我正在使用 Spring 和 Binstub（都更新到最新版本）。
这是我的 application.rb 文件的顶部：
# frozen_string_literal: true
require_relative 'boot'
require 'csv'
require 'rails'
# Pick the frameworks you want:
require 'active_model/railtie'
require 'active_job/railtie'
require 'active_record/railtie'
# require "active_storage/engine"
require 'action_controller/railtie'
require 'action_mailer/railtie'
# require 'action_mailbox/engine'
# require 'action_text/engine'
require 'action_view/railtie'
# require 'action_cable/engine'
require 'sprockets/railtie'
# require 'rails/test_unit/railtie'
require 'google/apis/gmail_v1'
require 'google/api_client/client_secrets'
# Require the gems listed in Gemfile, including any gems
# you've limited to :test, :development, or :production.
Bundler.require(*Rails.groups)
module BuildPlanner
class Application < Rails::Application
# Initialize configuration defaults for originally generated Rails version.
config.load_defaults 6.0
...
还有什么我应该看的地方吗？
原来这似乎与rails_admin有关。
我是怎么学到的：
Someone else 表达了我对警告消息的不满，并寻求更多帮助来追踪问题。
One response 建议将 pp caller_locations 放在正在自动加载的文件之一的顶部。这样做给了我一个我可以使用的回溯。那时我注意到 rails_admin 在每个路径中都出现了。
我注意到 config/initializers/rails_admin.rb 中已经有一大堆 require 语句：
require 'money-rails/rails_admin'
require 'rails_admin/adapters/active_record'
require 'application_record'
require 'user'
require 'event'
require 'registration'
require 'location'
require 'technology'
require 'supplier'
require 'component'
require 'part'
require 'material'
require 'count'
require 'inventory'
require 'extrapolate_component_part'
require 'extrapolate_material_part'
require 'extrapolate_technology_component'
require 'extrapolate_technology_part'
require 'extrapolate_technology_material'
为了好玩，我把它们都注释掉了，然后 运行 一个 RSpec 测试。我的警告消息突然变得超长，并且出现了更多实例：
DEPRECATION WARNING: Initialization autoloaded the constants ApplicationHelper, EventsHelper, FontAwesome::Rails::IconHelper, DeviseHelper, ErrorHandler, ApplicationController, ApplicationRecord, User, Event, Registration, Location, Technology, Component, Part, Material, Supplier, Count, Inventory, ExtrapolateComponentPart, ExtrapolateMaterialPart, ExtrapolateTechnologyComponent, ExtrapolateTechnologyPart, and ExtrapolateTechnologyMaterial.
所以我决定在我以前的实例中添加：
require 'application_helper'
require 'events_helper'
require 'devise_helper'
require 'error_handler'
require 'application_controller'
...对于我已经很长的列表，我的警告信息，除了 FontAwesome::Rails::IconHelper 之外的所有信息都消失了。我想我也可以得到那个，如果我能找出正确的文件路径的话。
