删除助手时出现Rails 5动作控制器路由错误

Question

删除相应控制器的帮助程序时，出现以下错误：

Couldn't find CompaniesHelper, expected it to be defined in helpers/companies_helper.rb

Application Trace | Framework Trace | Full Trace
app/controllers/companies_controller.rb:1:in `<main>'

我对此感到困惑，因为我不认为companies_controller依赖于帮助者。 在这个假设下我也许是错的？

我尝试在我的development.rb中删除包括无效的帮助程序。

任何帮助，将不胜感激！

谢谢

对于Rails 5+， 默认情况下，每个控制器将包括所有助手。

Pre Rails 5，控制器将包括一个与其名称匹配的助手。 进行如上所述的设置将返回Pre-Rails 5行为。

要设置助手的Pre-Rails-5行为，请在config / development.rb中进行设置

 config.action_controller.include_all_helpers = false
