如何使用Puma在Heroku上部署Michael Hartl的Rails教程应用程序

我是新来的，所以如果我的帖子不符合标准，我会道歉。

我正在做Mike Hartl的Rails教程，在第7章的末尾，我对heroku的推动不起作用。 Heroku声明

  

“应用程序错误应用程序和您的页面出错   无法提供服务。请稍后再试。

     

如果您是应用程序所有者，请查看日志以获取详细信息。“

它本地工作正常，我不知道是什么导致它，因为它在第6章结束时工作正常。我认为这是我的宝石文件中的东西，但我评论了两个添加的宝石，它做了一样。

用户模型： 

class User < ActiveRecord::Base
 before_save { self.email = email.downcase }
 validates :name, presence: true, length: { maximum: 50 }
 VALID_EMAIL_REGEX = /\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i
 validates :email, presence: true, length: {maximum: 200 },
        format: { with: VALID_EMAIL_REGEX },
        uniqueness: { case_sensitve: false }
 has_secure_password
 validates :password, length: { minimum: 5 }
end

的Gemfile： 

source 'https://rubygems.org'
gem 'rails', '4.2.1'
gem 'bootstrap-sass',       '3.2.0.0'
gem 'pg'
gem 'bcrypt',               '3.1.7'
gem 'sass-rails', '~> 5.0'
gem 'uglifier', '>= 1.3.0'
gem 'coffee-rails', '~> 4.1.0'
gem 'rails_12factor'
gem 'puma',           '2.11.1'
gem 'jquery-rails'
gem 'turbolinks'
gem 'jbuilder', '~> 2.0'
gem 'sdoc', '~> 0.4.0', group: :doc
group :development, :test do
gem 'byebug'
gem 'web-console', '~> 2.0'
gem 'spring'
end

看起来我错过了什么吗？我取出了我的Procfile，因为我拿出了Puma宝石，但这似乎没有什么区别。不确定我是否还需要包含任何其他文件...

非常感谢任何帮助。谢谢！

是的，看起来你错过了config /文件夹中的puma配置。

No such file or directory - config/puma.rb (Errno::ENOENT)

来自heroku文档：

https://devcenter.heroku.com/articles/deploying-rails-applications-with-the-puma-web-server#config

在config / puma.rb或您选择的路径上为Puma创建配置文件。对于简单的Rails应用程序，我们建议使用以下基本配置：

workers Integer(ENV['WEB_CONCURRENCY'] || 2)
threads_count = Integer(ENV['MAX_THREADS'] || 5)
threads threads_count, threads_count

preload_app!

rackup      DefaultRackup
port        ENV['PORT']     || 3000
environment ENV['RACK_ENV'] || 'development'

on_worker_boot do
  # Worker specific setup for Rails 4.1+
  # See: https://devcenter.heroku.com/articles/deploying-rails-applications-with-the-puma-web-server#on-worker-boot
  ActiveRecord::Base.establish_connection
end
