求前辈知道，docker 安装之后宝了这个错误

这个应该是你自己的代码写的有点问题吧，你的stats_controller的第 11 行是什么？把你访问的这个 controller 的代码贴上来看一下

您好，我是直接安装的 docker 发行版本，没有下载和修改过代码

报错的是 https://github.com/ruby-china/homeland/blob/master/app/controllers/admin/stats_controller.rb#L11

result[:count] = klass.unscoped.count # Line 11
...
def klass                                                                      # Line 17
  params[:model].camelize.safe_constantize
end

你的 url 里是model=note，似乎代码里并没有这个 model。换一个别的试试看。

那有可能是我 docker 部署的配置文件没对吗，没有加载到 node 纪事本模块，请问要怎么配置呀，配置了也重启了，就是没效果
