Rails Heroku應用程序錯誤

Question

我的項目在當地運作良好。 我把它部署到了Heroku。 我有一些錯誤，應用無法在那里運行。 我正在使用帶有postgresql的rails 4。 無法理解為什么會這樣。 在我看來，沒有創建數據庫。 我應該在database.yml上添加指定生產設置嗎？

database.yml的

development:
  adapter: postgresql
  encoding: utf8
  database: test_store_dev
  pool: 5
  username: mike
  password: mike
  host: 127.0.0.1

test:
  adapter: postgresql
  encoding: utf8
  database: test_store_test
  pool: 5
  username: mike
  password: mike
  host: 127.0.0.1

從日志：

~/workspace/test_store$ heroku logs --tail

Answer 1

（PG :: UndefinedTable：錯誤：關系“類別”不存在

你沒有表“類別”

heroku run rake db:migrate

Answer 2

你只需要heroku run rake db:migrate 。 數據庫將由heroku自己創建
