Rails Admin和Heroku的路由错误

Question

我遇到了问题让Rails管理员与Heroku一起玩。当管理员登录在我得到一个路由错误，这里是错误：

No route matches {:controller=>"rails_admin/main"} 

我相信，因为这个代码在我application.html.erb出现此错误：

<% if current_admin %> 
    <%= link_to "Admin Dashboard", rails_admin.index_path %> 
<% end %> 

看来，当发生我打电话给link_to中的rails_admin.index_path。但是，如果我去myurl/admin它让我看到管理仪表板罚款。此外，在我的开发和生产环境中，一切工作正常。

输出的rake routes：

对我来说，解决办法是改变

rails_admin.index_path 

到

rails_admin.dashboard_path 

不知道为什么它不工作的其他方式在生产周围，但这会做。
