未初始化的常量ActionController :: Caching :: Sweeper

Question

当预编译生产环境时，我收到一个未初始化的常量ActionController :: Caching :: Sweeper错误（与heroku相同）。在开发环境和localhost中，一切正常。 Thx有任何建议。

** Invoke assets:environment (first_time) 
** Execute assets:environment

Answer 1

这是rails-observers中的一个错误。 https://github.com/rails/rails-observers/issues/4

Answer 2

THX @khustochka到把我在正确的轨道上

我解决我的问题有：

安装宝石'rails-observers' https://github.com/rails/rails-observers

然后我加入到production.rb

config.dependency_loading = true if $rails_rake_task 
    config.active_record.observers = :contact_observer 

由于我得到了未初始化的常量ActiveModel :: Obser我做了rake db:migrate RAILS_ENV=production 和rake asset precompile RAILS_ENV=production

版本错误

我创建的应用程序/模型文件contact_observe.rb

class ContactObserver < ActiveRecord::Observer 
    observe :user 
end 

后，我的问题是固定的

Answer 3

发生这种情况，因为spree_reviews扩展取决于已在Rails 4中删除的Rails功能。请在该项目上提出有关此问题的问题。

Answer 4

这是由于bug in the rails-observers gem。 The bug has been fixed，但修复尚未达到rubygems.org。

从GitHub使用的rails-observers版本，通过更换这条线在你Gemfile：

gem 'rails-observers' 

有了这一个：

gem 'rails-observers', git: 'https://github.com/rails/rails-observers.git'
