Rails 5とHeroku - Postgresが動作しない

Question

私は見つけることができるすべてのチュートリアルに従っていますが、まだ私のRails 5アプリケーションをHerokuに正しく配備できないようです。私はサイトを稼働させることができますが、データベースに接続していないようです（私はPostgresに切り替えました）ので、ログインできません。私もサイトの一部のページにアクセスすることはできません - 私はエラーを取得しない、ただ空白のページ。どんな助けも本当に素晴らしいでしょう！
ありがとうございます！ここ
はコードです：

のPostgresの問題：

database.ymlの

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
