gem 'gon' - Quotes#index 中的名称错误，常量未初始化 ActionView::CompiledTemplates::Gon，Rails 5

Question

我正在尝试使用 gem 'gon' 但运行进入上述错误，说明；

namer error in Quotes#index

 Showing /Users/jamesbkemp/Code/QuoteEngine/app/views/layouts/application.html.erb where line #5 raised:

未初始化常量ActionView::CompiledTemplates::Gon

知道问题可能是什么和/或关于替代 gem 的任何建议，以使将控制器变量传递到 javascript 更容易吗？

谢谢

application.html.erb，注意第 5 行；

我想为你的案例提供帮助，因为我也在 rails 5 中使用 gon 并且它正在工作

运行捆绑包安装后，
打开 app/views/layouts/application.html.erb 并放在标签正文 <%= Gon::Base.render_data %>

做一些测试打开你的控制器并创建 gon 数据（例如下面我给你 10 个用户数据

gon.users = User.limit(10)

打开你的咖啡并用日志测试

alert gon.users

并且不要忘记重新启动您的 rails 服务器命令
