我在使用 heroku 部署 rails 3.2 应用程序时遇到问题，加载应用程序时出现上述错误。这是我的日志：

我对 rails/heroku 相当陌生，因此非常感谢任何帮助。经过大量开发后，我正在尝试部署。对于未来，在开发过程的早期推送到heroku，然后继续推送会更好吗？谢谢！

  1. ActiveRecord::StatementInvalid (PG::Error: ERROR: 关系“houses”不存在。

    我会说houses数据库中的表丢失了，您可以使用 heroku toolbelt 运行迁移：heroku run rake db:create --app my_app2- 创建数据库，heroku run rake db:migrate --app my_app2- 运行迁移。使用Capistrano设置部署将使用一个命令为您运行所有内容。

    Heroku 工具带 - https://toolbelt.heroku.com/

    Capistrano - https://github.com/capistrano/capistrano

  2. 对于未来，在开发过程的早期推送到heroku，然后继续推送会更好吗？

    在我目前正在与我们的团队合作的项目中，我们有 2 个heroku实例，意味着 2 个应用程序，一个用于生产，第二个用于测试，首先将更改推送到测试应用程序，如果一切顺利，我们将其移至生产环境。

当我发现您正在sqlite用于开发时：

Heroku 使用 postgresql。https://devcenter.heroku.com/articles/sqlite3

像这样将其删除sqlite3或移动到development group您的 Gemfile 中：

group :development do
  gem 'sqlite3'
end

group :production do
  gem 'thin'
  gem 'pg'
end

删除 Gemfile.lock 运行bundle install --without production

git add .
git commit -am "bundle updating sqlite3"
git push heroku master

或者更简单，只需在本地计算机上使用 PG 进行开发。你可能有一些 sql 语句可以在 sqlite 中工作，而不能在 heroku 上的 postgres 中工作，所以我会在你的地方使用 PG 进行开发。
