如何在Heroku上使用Puma部署Michael Hartl的Rails教程應用

我是新來的，所以如果我的帖子不符合標準，我很抱歉。如何在Heroku上使用Puma部署Michael Hartl的Rails教程應用

我在做Mike Hartl的Rails教程，在第7章結尾處，我對heroku的推動不起作用。 Heroku的規定

「應用程序錯誤應用程序發生錯誤，您的網頁無法送達，請稍後重試。

如果您是應用的所有者，請檢查您的日誌詳細信息「。

它本地工作很好，我不知道是什麼導致它，因爲它是在第6章的結尾工作正常，我還以爲是什麼在我的寶石文件，但我註釋掉添加的兩種寶石和它做了同樣的事情。

Heroku的日誌：

用戶模型：

class User < ActiveRecord::Base 
before_save { self.email = email.downcase } 
validates :name, presence: true, length: { maximum: 50 } 
VALID_EMAIL_REGEX = /\A[\w+\-.][email protected][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

它看起來像我我錯過了什麼？自從我拿出彪馬寶石後，我拿出了我的Procfile，但這似乎沒有什麼區別。不知道是否需要包括任何其他文件以及...

任何幫助將不勝感激。謝謝！

是的，看起來你缺少配置/文件夾內的美洲獅配置。

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

從Heroku的文檔：

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

創建在配置/ puma.rb或您所選擇的路徑彪馬的配置文件。對於簡單的Rails應用程序，我們推薦以下基本配置：

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
