Question

我使用了很多我的rails应用程序在开发中我每天都会得到这些错误1-2次

NoMethodError: undefined method `users_url' for #<RegistrationsController:0x007f14cd6cd958>

在unicorn.log中我发现了这些错误

(facebook) Callback phase initiated.
(facebook) Callback phase initiated.
(facebook) Callback phase initiated.
(facebook) Callback phase initiated.
(facebook) Callback phase initiated.
(facebook) Callback phase initiated.

，唯一的解决方案是

 sudo service unicorn_myapp stop

然后再次使用

启动它

 sudo service unicorn_myapp start

我检查了我的用户模型和相关模型的回调，但一切正常，注册工作非常好，重新启动unicorn之前我说过

我正在使用ruby 2.1.5和rails 3.2.21

Answer 1

我不确定错误是什么，但是通过查看gem源代码，def polymorphic_url方法，

（actionpack-4.1.5/lib/action_dispatch/routing/polymorphic_routes.rb

# -- some code
inflection = if options[:action] && options[:action].to_s == "new"
          args.pop
          :singular
        elsif (record.respond_to?(:persisted?) && !record.persisted?)
          args.pop
          :plural
        elsif record.is_a?(Class)
          args.pop
          :plural
        else
          :singular
        end

看来，您的resource对象已成为收集或User.new，然后它变为:plural并为您提供该错误。我的猜测是尝试调试那个方向，HTH
