Question

当我检查Webrick日志时，我注意到以下内容：

Started GET "/tags" for 127.0.0.1 at 2015-10-30 08:16:58 +0000
/usr/local/rvm/gems/ruby-2.2.2/bundler/gems/rails-f7d0a3ba7e9e/actionpack/lib/action_controller/api.rb:110: warning: already initialized constant ActionController::API::MODULES

我检查了以下Github更新：

https://github.com/plataformatec/devise/issues/3690

但是当我尝试按照建议进行更新时：

https://github.com/rails/rails/pull/21151

我在这些文件中找不到上述信息：

https://github.com/rails/rails/commit/fd2508522c341c3f708219b5fc1834f24caf04e3

有什么想法吗？谢谢！

我有这个问题，我在git上找到了一些解决方案，我没有链接，但是就是这样：

您需要添加到application_controller.rb：

def self.helper_method(*); end

如果你对...undefined method 'helper'...遇到同样的问题，请添加：

def self.helper(*); end

这解决了我的问题。在我看来它不是最好的解决方案，但是直到设计将支持rails 5并且他们将它固定在他们身边，这种解决方法有效......
