Heroku上的Rails：ActiveRecord :: StatementInvalid，重置和遷移不起作用

Question

嘗試打開我剛剛推送到heroku的應用程序時出現以下錯誤，本地一切正常。 我已經嘗試使用rake db：reset，pg：reset，db：migrate刪除和重新推送，並且所有表都具有復數名稱。 每個步驟后我也都重新啟動了。數據庫顯示在Heroku儀表板中。 任何幫助將不勝感激，我希望將其用作即將進行的項目的概念證明，但與此同時，我已經徹底碰壁了！

ActiveRecord :: StatementInvalid（PGError：錯誤：關系“帖子”不存在

我基於博客教程構建了該應用程序，並且運行良好，此后我又添加了2個其他表格（在其他教程之后）並設置了使用Nokogiri的rake任務，但我不知道該怎么破壞鏈接到職位表？

Answer 1

您在heroku使用postgreSQL，因此您必須將config / database.yml文件更改為

production:
  adapter: PostgreSQL
  database: production
  pool: 5
  timeout: 5000

然后再次遷移

 1)heroku run rake db:reset 
 2) heroku run rake db:migrate 
 3)heroku restart 
 4)heroku open

在您的生產組中添加稀薄的寶石

group :production do
   gem 'thin'
end
