Rails 3 - 生产模式中的开发错误

标签: ruby-on-rails passenger production

我在生产服务器上使用Rails,Passenger(均为3.0.5)和Nginx。正如我所听到的,Rails应该显示public/404.htmlpublic/500.html而不是ActiveRecord::RecordNotFoundUnknown action等开发错误,但这不会发生。我试图删除config.ru文件并在nginx.conf中设置rack_env或rails_env,但没有任何帮助。

这是我的nginx.conf:

worker_processes  1;

events {
    worker_connections  1024;
}

http {
    passenger_root /home/makk/.rvm/gems/ruby-1.9.2-p0/gems/passenger-3.0.5;
    passenger_ruby /home/makk/.rvm/bin/passenger_ruby;
    #passenger_ruby /home/makk/.rvm/wrappers/ruby-1.9.2-p0/ruby;

    include       mime.types;
    default_type  application/octet-stream;

    sendfile        on;
    keepalive_timeout  65;

    server {
        listen       80;
        server_name  localhost;

        location / {
            root   /home/makk/projects/1server/deploy/current/public;
            index  index.html index.htm;
            passenger_enabled on;
            rack_env production;

            recursive_error_pages on;

            if (-f /home/makk/projects/1server/maintenance.html) {
              return 503;
            }

            error_page 404 /404.html;
            error_page 500 502 504 /500.html;
            error_page 503 @503;
        }

        location @503 {
            error_page 405 = /maintenance.html;

            # Serve static assets if found.
              if (-f $request_filename) {
              break;
            }
            rewrite ^(.*)$ /maintenance.html break;
        }

        location ~ ^(\/phpmyadmin\/)(.*)$ {
        fastcgi_pass    127.0.0.1:9000;
        fastcgi_index   index.php;
        fastcgi_split_path_info         ^(\/phpmyadmin\/)(.*)$;
        fastcgi_param   SCRIPT_FILENAME /usr/share/phpmyadmin/$fastcgi_path_info;
        include         fastcgi_params;
        }
    }
}

似乎这个问题与this one重复,但没有可行的建议。

UPD :我在同一台PC上同时拥有开发和制作应用。在生产中,由于config.consider_all_requests_local = false方法,Rails忽略local_request?(在/config/environments/production.rb中)。因此,下面列出了一种可能的解决方案(取自here):

# config/initializers/local_request_override.rb
module CustomRescue
  def local_request?
    return false if Rails.env.production? || Rails.env.staging?
    super
  end
end

ActionController::Base.class_eval do
  include CustomRescue
end

或者对于Rails 3:

class ActionDispatch::Request
 def local?
   false
 end
end

要在Rails 3中使用此功能,您必须执行以下操作:

首先,创建404和500错误页面。我把我放在app/views/errors/404.html.erbapp/views/errors/500.html.erb

其次,将以下内容添加到application_controller.rb:

unless Rails.application.config.consider_all_requests_local
  rescue_from Exception, :with => :render_error
  rescue_from ActiveRecord::RecordNotFound, :with => :render_not_found
  rescue_from AbstractController::ActionNotFound, :with => :render_not_found
  rescue_from ActionController::RoutingError, :with => :render_not_found
  rescue_from ActionController::UnknownController, :with => :render_not_found
  rescue_from ActionController::UnknownAction, :with => :render_not_found
end

def render_error exception
  Rails.logger.error(exception)
  render :template => "/errors/500.haml", :status => 500
end

def render_not_found exception
  Rails.logger.error(exception)
  render :template => "/errors/404.haml", :status => 404
end

最后,让你的production.rb不考虑所有本地请求:

config.consider_all_requests_local = false

PS:请记住,当发生完整的路由错误时 - 即绝对没有路由匹配,而不仅仅是ActiveRecord NotFound错误,public / 404.html将会显示,因此最好将其设置到位。我通常只是将它重定向到我的errors_controller,这可以确保后面提到的任何404错误都没有被正确地重定向到ErrorsController。

<script type="text/javascript">
<!--
window.location = "<%= request.host_with_port %>/errors/404"
//-->
</script>

仅在某些控制器中获取错误

class AdminController < ApplicationController
  rescue_from Exception, :with => :render_simple_error if Rails.env.production?
  def render_simple_error(e)
    render :text => "#{e.message} -- #{e.class}<br/>#{e.backtrace.join("<br/>")}"
  end
end

答案 2 :(得分:2)

root声明移至“服务器”块,以便服务器在收到5XX,4XX错误时可以使用Rails应用程序定义的错误处理页面。

或者将error_page指令添加到正在使用乘客的位置块,以便错误处理程序可以在需要时解析Rails应用程序公共目录中的public/5xx.html

如果您的应用未提供该页面且nginx无法看到静态页面,则无法提供您想要的页面。

在apache乘客上我使用了apache配置选项 PassengerFriendlyErrorPages关闭。
