我正在使用
private_pub将订阅客户端的通知推送给我的用户.在我的application.html.haml中,我有：
...
= javascript_include_tag 'application'
= subscribe_to "/#{@user.access_token}/notifications"
...
subscribe_to帮助程序在开发中工作正常.部署到生产时,会记录以下错误：
ActionView::Template::Error (undefined method `subscribe_to' for #<#<Class:0x00000001f372e8>:0x00000001fded90>):
5: = stylesheet_link_tag 'application',:media => 'all'
6: = include_gon(:init => true)
7: = javascript_include_tag 'application'
8: = subscribe_to "/#{@user.access_token}/notifications"
9: = csrf_Meta_tags
10:
11: %body
app/views/layouts/application.html.haml:8:in `_app_views_layouts_application_html_haml__1867651381877570337_14592040'
如何在生产环境中访问此帮助程序方法？
