答案 0 :(得分：1)
您需要关注的错误如下：NoMethodError（未定义的方法`player_1'代表nil：NilClass）
迁移数据库后，本地数据库中的数据将不在生产数据库中。方法player_1被调用的东西是零，很可能是你本地数据库上没有的东西，因为在部署之前你会在本地看到错误。
在db / seeds.rb上构建种子文件，只需运行以下命令即可将数据输入生产数据库：
heroku run rake db:seed
在种子文件中，您可以像在应用程序中的其他位置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
