页面未在 heroku 上显示 - heroku [路由器]：状态 = 500

Question

谁能告诉我如何纠正这个错误，我不知道，我已经尝试了 stackoverflow 上其他页面的所有帮助。

我已经尝试了以下所有其他人推荐的建议：

• suggestion1: log entries
• gem 'rails_12factor'
• 更改config.log_level = :debug
• rake db:migrate
• heroku config:set

但我不确定为什么会出现以下错误。非常感谢您的帮助和建议。

Answer 1

这似乎是一个数据库错误，通常在您只在本地运行迁移而忘记在 heroku 上运行迁移时发生 盒子。运行

heroku run rake db:migrate

在您将最新的 git 提交推送到它之后，在您部署的机器上运行迁移。

Answer 2

这个问题已经解决了。谢谢大家

• 这是由于使用 heroku 对数据库的访问受限。
• 我在 heroku DATABASE_URL 上，它允许最多 10'000 行代码。我有 10'891 行代码
• 要了解有关 pg 数据库的更多信息，请键入：heroku pg:info --app yourAppName
• 我必须 [在管理面板中] 升级到 HEROKU_POSTGRESQL_GOLD_URL 或者您可以简单地在终端输入 heroku pg:upgrade HEROKU_POSTGRESQL_GOLD --app yourAppName

• 在升级之前确保维护已开启。在终端类型中：heroku maintenance:on

• 我选择的新数据库 URL 目前是 $9/mth - 这允许更多行代码

• 在终端中升级后，键入：heroku pg:promote HEROKU_POSTGRESQL_GOLD 将其设置为默认数据库

• 如果您当前有数据存储在以前，请键入：heroku pg:copy DATABASE_URL HEROKU_POSTGRESQL_GOLD --app yourAppName 以传输数据
