启动Sidekiq队列时的循环依赖关系
加载sidekiq队列时出现以下错误：

我使用以下方法加载lib和worker：
config.autoload_paths += %W( #{config.root}/app/workers #{config.root}/lib )
文件处理器类是：
class FileProcessor def self.update_totals(source_id, update_type) total = Total.first if total == nil total = Total.new end source = Source.find(source_id) if update_type.to_s == "ARTICLE" source.number_of_articles = source.number_of_articles + 1 total.number_of_articles = total.number_of_articles + 1 elsif update_type.to_s == "PAGE" source.number_of_pages = source.number_of_pages + 1 total.number_of_pages = total.number_of_pages + 1 elsif update_type.to_s == "RSS" source.number_of_rss_articles = source.number_of_rss_articles + 1 total.number_of_rss_articles = total.number_of_rss_articles + 1 end source.save total.save end end
我环顾四周但找不到解决这个问题的方法。
有什么建议？
好的，这是一个authoload / eagerload问题。 我找到了一些关于GH处理这个问题的讨论。 我仍然需要在生产中测试，但添加：
config.autoload_paths += %W( #{config.root}/app/workers #{config.root}/lib ) config.eager_load_paths += %W( #{config.root}/app/workers #{config.root}/lib )
到application.rb修复了问题。
