当客户下订单时，我的应用程序崩溃了。

我真的很绝望，因为我需要production.log弄清楚是什么破坏了应用程序！！

我登录了 :~/mystore/current/log$ nano production.log

而且似乎production.log自 2017 年 23 月 5 日以来就没有更新过。

这是最后几行 production.log

 I, [2017-05-23T11:12:35.067624 #1060]  INFO -- : Completed 404 Not Found in 27ms (ActiveRecord: 3.0ms)
F, [2017-05-23T11:12:35.069957 #1060] FATAL -- :
ActiveRecord::RecordNotFound (Couldn't find Label with 'id'=10):
  app/controllers/labels_controller.rb:21:in `set_label'

现在我不明白为什么我的应用程序今天崩溃了。这很奇怪，因为我总是能够通过production.log

这是里面的设置 production.rb

  config.log_level = :info

 config.logger = ActiveSupport::Logger.new('/tmp/foo.log') 
 config.logger.info "SMTP_ADDR: #{ENV["SMTP_ADDRESS"].inspect}"
 config.log_formatter = ::Logger::Formatter.new

在deploy.rbI'm sim-linking中，不知道是否与此有关。

set :linked_files, %w{config/database.yml config/secrets.yml config/application.yml}
set :linked_dirs, %w{log tmp/pids tmp/cache tmp/sockets vendor/bundle public/system} …

我在生产中无法访问rails控制台.

我曾经Capistrano将应用程序部署到VPS

如果我cd deploy@myapp:~/myapp/current$并在bundle exec rails c那里运行,我总是得到用于创建新rails项目的选项列表,比如rails new

我也试着bundle exec rails console --production和rails console等等都具有相同的结果.

问题是我必须能够访问控制台,因为我必须创建一个管理员用户 active admin

可能值得补充一点,我在Ubuntu 16上使用Passenger/Capistrano和Nginx

有谁知道这里发生了什么？难道我做错了什么？

跑完后RAILS_ENV=production bundle exec rails c我收到这条消息

 Looks like your app's ./bin/rails is a stub that was generated by Bundler.

 In Rails 4, your app's bin/ directory contains executables that are  versioned
 like any other source code, rather than stubs that are generated on demand.

  Here's how to upgrade: …

我正在尝试使用Gibbon和Mailchimp进行基本邮件列表设置.

当我启动我的rails服务器时,我经常遇到这个错误 rails s

我甚至降级到了版本 gem 'gibbon', '~>1.2.0'

但我的日志仍然是这样的

嗨我正在将我的第一个Rails应用程序部署到Ubuntu 16服务器上,Capistrano除了图像没有在生产环境中显示外,一切顺利.

在生产服务器上,映像位于此路径中: /myapp/current/public/assets

但是,如果我在浏览器中看到这个,我的破碎图像链接给了我这个(见图片),这是标题图像的断开链接.

奇怪的是,有一个.svg文件在/myapp/current/public/assets浏览器中完美显示,下图是显示的路径

这是我的 Capfile

# Load DSL and set up stages
 require "capistrano/setup"

# Include default deployment tasks
require "capistrano/deploy"


set :rbenv_type, :user # or :system, depends on your rbenv setup
set :rbenv_ruby, '2.3.1'


require 'capistrano/rbenv'

require 'capistrano/bundler'
require 'capistrano/rails'


# Load custom tasks from `lib/capistrano/tasks` if you have any defined
Dir.glob("lib/capistrano/tasks/*.rake").each { |r| import r }

这是 config/deploy.rb

# config valid only for current version of Capistrano
lock '3.6.1' …

在我的应用程序中,我有categories,labels 他们都属于products

在管理面板中,用户可以添加产品,创建标签和类别,然后为产品分配类别和标签.

当我创建标签时,名称在标签面板中正确显示(见照片)

问题是标签名称在分配给产品时没有正确显示(见下图),但显示了类别名称.这很奇怪,因为两列都具有相同的设置.

在Admin products panel标签上显示数字Label#1``Label#2等(见下图)

在_navbar.html.erb我有这个代码显示类别和标签...并在那里正确显示.

                <ul class="dropdown-menu" role="menu">
                    <% @categories.each do |category| %>
                        <li><%= link_to category.name, category %></li>
                    <% end %>         
                </ul>
            </li>       
              <li class="dropdown full-width">
                <a href="#" class="dropdown-toggle" 
                data-toggle="dropdown">
                    Labels
                </a>
                <ul class="dropdown-menu" role="menu">
                   <% @labels.each do |label| %>
                        <li><%= link_to label.label_name, label %></li>
                    <% end %>    
                </ul>
            </li>       

我在这里错过了什么吗？我看不出为什么标签显示不正确.

有没有人与活动管理员有相同或类似的问题？

谁能看看这个？

提前致谢

这是 app/admin/category.rb

ActiveAdmin.register Category do

 permit_params :name

end

在app/admin/label.rb这里有代码:

ActiveAdmin.register …
