我正在经历一个月的轨道，我一直在更新东西以使其与rails 4一起使用。除非我尝试让postgresql数据库与网站一起工作，否则我已经成功了。
我在网站上收到应用程序错误，当我梳理日志时，我得到的不是描述性错误：
at=error code=H10 desc="App crashed" method=GET path="/" host=omrails-scj.herokuapp.com request_id=cc4ff49d-c3dc-41ee-b999-730cc2a56628 fwd="98.193.89.149" dyno= connect= service= status=503 bytes=
这是github地址：https://github.com/CaptainChemist/omrails
这是我的宝石文件：
gem 'rails', '~> 4.2.0.beta2'
gem 'jquery-rails', '~> 4.0.0.beta2'
gem 'devise'
gem 'simple_form'
gem 'turbolinks'
gem 'jbuilder', '~> 2.0'
gem 'sdoc', '~> 0.4.0', group: :doc
gem 'sass-rails', '~> 5.0.0.beta1'
gem 'uglifier', '>= 1.3.0'
gem 'coffee-rails', '~> 4.0.0'
gem 'bootstrap-sass'
gem 'autoprefixer-rails'
group :production do
gem 'pg'
gem 'rails_12factor'
end
group :development, :test do
gem 'sqlite3'
end
关于推动英雄的一个问题是如何设置production.rb文件。我添加了这段代码：
config.action_mailer.default_url_options = { :host => 'omrails-scj.herokuapp.com:3000'}
这是正确的方法吗？我运行了rake db：migrate并且运行时没有任何问题。另外，除了heroku日志之外还有更好的去处 - 看看发生了什么？
感谢您的帮助！
编辑：我认为这些是完整的日志感谢您让我发布那些我没有意识到我在开始时遇到错误的问题。
我的应用程序控制器是：
class UsersController < ApplicationController::Base
将其更改为固定它：
class UsersController < ApplicationController
