Question

我一直在关注我能找到的每个教程，但仍然无法在Heroku上正确部署我的Rails 5应用程序。我可以启动并运行该站点，但似乎没有数据库连接（我切换到Postgres），所以我无法登录或任何东西。我也无法访问网站上的某些页面 - 我没有收到错误，只是一个空白页面。任何帮助都会非常棒！
谢谢!!
以下是代码：

Postgres问题：

的database.yml

default: &default
  adapter: postgresql
  pool: 5
  timeout: 5000
  host: ""

development:
  adapter: postgresql
  encoding: unicode
  database: demo_test_development
  pool: 5
  username: Brandon
  password: "password"
  timeout: 5000

test:
  adapter: postgresql
  encoding: unicode
  database: demo_test_test
  pool: 5
  username: Brandon
  password: "password"
  timeout: 5000

您的应用是否在本地计算机上正常运行？
您是否通过以下命令在heroku上运行迁移文件：

heroku run rake db：migrate
