Question

我正在尝试使用宝石＆＃39; gon＆＃39;但遇到上述错误，说明;

namer error in Quotes#index

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

未初始化的常量ActionView :: CompiledTemplates :: Gon

任何想法可能是什么问题和/或任何关于替代宝石的建议使控制器变量更容易传递到javascript中？

由于

application.html.erb，注意第5行;

    <!DOCTYPE html>

我想帮助你处理你的情况，因为我还在轨道5中使用gon并且它正在工作

运行捆绑安装后，
打开app / views / layouts / application.html.erb 并置于标签主体＆lt;％= Gon :: Base.render_data％＆gt;

打开您的控制器进行一些测试并创建gon数据（例如，下面我给了您10个用户数据

gon.users = User.limit(10)

打开咖啡，用日志测试

alert gon.users

并且不要忘记重启rails服务器命令
