我在使用Ubuntu + Apache + Passenger时遇到这个错误。问题是我没有使用任何数据库或模型。

至少在www.example.com之前5.2.4.3，ActiveStorage似乎在加载Rails config/initializer之后初始化并将其方法注入ActiveRecord。如果任何初始化程序使用任何调用ActiveStorage宏的模型，如has_one_attached或has_many_attached，那么这些方法在那时就丢失了。
例如，如果您有一个使用has_one_attached :image的User模型，并且您使用User作为您的Devise模型，则Device初始化程序将引用User，并且当加载User时，has_one_attached方法将丢失。
我在config/application.rb的末尾添加了这段取自active_storage/engine的代码，它对我很有效。

# config/application.rb
require "active_storage/attached"
ActiveSupport.on_load(:active_record) do
  extend ActiveStorage::Attached::Macros
end

是否安装了ActiveStorage？

rails active_storage:install:migrations
rails db:migrate

如果没有使用任何DB，则不能使用它。

对我来说，删除这条线已经解决了

配置文件/初始化程序/active_admin.rb

config.before_action :set_admin_locale

在Rails 6.1上，这似乎是可行的：

# config/application.rb
ActiveSupport.on_load(:active_record) do
  include ActiveStorage::Reflection::ActiveRecordExtensions
  ActiveRecord::Reflection.singleton_class.prepend(ActiveStorage::Reflection::ReflectionExtension)
  include ActiveStorage::Attached::Model
end

我从Argenis的答案开始找到了这个解决方案，并将其与the one in this other SO混合
