Ruby on rails Rails 5和Heroku-Postgres不工作

我一直在遵循我能找到的每一个教程，但似乎仍然无法在Heroku上正确部署我的Rails 5应用程序。我可以让网站启动并运行，但似乎没有数据库连接（我切换到Postgres），所以我无法登录或做任何事情。我也不能访问网站上的一些页面-我没有得到一个错误，只是一个空白页面。任何帮助都会非常好！
谢谢！！
代码如下：

博士后问题：

数据库.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

您的应用程序是否在本地计算机上正常运行

您是否已通过以下命令在heroku上运行迁移文件：

heroku运行rake数据库：迁移

---

你在Heroku上运行迁移了吗

heroku运行rakedb:migrate

这里的指令：-，对于我使用过的所有rails版本都很好。
