ubuntu 14.2/ rails 4.2.3/ nginx1.8 下面是自己找到但是不知道怎么解决的问题，..,还有能顺便问一下，production 的数据库在哪里吗？

500 Internal Server Error

用的是 ubuntu 14.2/ ruby 2.1.2 /rails 4.23 ,数据库迁移啊，都成功啦。应用目录是 /home/wyl/Hack 错误日志 我去了下面说的网址，给的方法是 sudo chmod g+x,o+x /Users/phusion/Sites/rack.test 但是没用嘞

2015/08/09 16:21:46 [alert] 2254#0: *14 Cannot stat '/home/wyl/Hack/config.ru': Permission denied (errno=13); This error means that the Nginx worker process (PID 2254, running as UID 65534) does not have permission to access this file. Please read this page to learn how to fix this problem: https://www.phusionpassenger.com/library/admin/nginx/troubleshooting/?a=upon-accessing-the-web-app-nginx-reports-a-permission-denied-error; Extra info, client: 127.0.0.1, server: localhost, request: "GET /favicon.ico HTTP/1.1", host: "localhost", referrer: 
"http://localhost/chats"

下面是 /opt/nginx/conf/nginx的配置

server {
       listen       80;
       server_name  localhost;
   root /home/wyl/Hack/public;
   passenger_enabled on;
   }

NOmethod Error 新手求助啦。。。。

arc_start — Fri, 07 Aug 2015 09:26:21 +0800

用的是 ubuntu15.x.x rails 是 4.23 问题是 undefined method `chat' for #Chat:0x007fe686475850 Extracted source (around line #29):

def create
  @chat = Chat.create(chat_params)
  if @chat.save
    redirect_to chats_path
  else

#下面是控制器的

def create
  @chat = Chat.create(chat_params)
  if @chat.save
    redirect_to chats_path
  else
    flash.now[:warning] = "error"
    render 'new'
  end
end

#这是视图

<div class:"col-md-4 col-md-offset-4">
<h1>new add comment panel</h1>

<hr>
<%= simple_form_for @chat do |f|%>
<div class="form-chat">
<%= f.input :title, input_html:{ class:"form-control"}%>
<%= f.input :desc, input_html:{ class:"form-control"}%>
</div>
<%= f.submit "submit", data:{disable_with: 'Submitting---'}, class:"btn btn-primary"%>
<%end%>
</div>

明明之前好好的，什么都没改，莫名其妙错了，求大家帮助呢！...
