当我在部署后导航到我的 heroku 应用程序时，我收到错误“我们很抱歉，但出了点问题”。这些是运行后的日志git push heroku master，然后是运行后的日志heroku run rake db:migrate。

任何建议都将不胜感激，因为我非常困在这里，而且我非常接近在网上找到一些东西。谢谢！

您需要关注的错误如下： NoMethodError (undefined method `player_1' for nil:NilClass)

迁移数据库后，本地数据库中的数据不会出现在生产数据库中。方法 player_1 正在被 nil 调用，很可能在本地数据库中不是 nil，因为在部署之前您会在本地看到错误。

在 db/seeds.rb 中构建种子文件将使您能够通过简单地运行将数据获取到生产数据库中：

heroku run rake db:seed

在种子文件中，您可以像在应用程序的其他地方一样在数据库表中创建行：

@user = User.create(username: 'ryanfrancis', email: 'ryan@example.com', password: 'password', password_confirmation: 'password')
@user.save
