在将 Rails 从 4.1 更新到 5.2 并添加响应者 gem 后，为我的控制器获取“未定义的方法`flash`”

[英]Getting "undefined method `flash`" for my controllers after updating Rails from 4.1 to 5.2 and added the responders gem

问题描述

I'm in the process of updating rails from 4.1 to 5.2 I added the responders gem so respond_with is present.我正在将 Rails 从 4.1 更新到 5.2，我添加了responders gem，因此存在responders 。 My ApplicationController now looks like this:我的 ApplicationController 现在看起来像这样：

class ApplicationController < ActionController::API self.responder = ApplicationResponder respond_to :html

However, when I call respond_with I get this error:但是，当我调用respond_with我收到此错误：

 NoMethodError: undefined method `flash' for #<MyController>

I noticed in the responders README that there is a flash responder, however I do not want to use that.我在响应者自述文件中注意到有一个快速响应器，但是我不想使用它。

add the following line to "config/environments/production.rb"将以下行添加到“config/environments/production.rb”

config.middleware.use ActionDispatch::Flash config.middleware.use ActionDispatch::Flash
