我的应用程序只在heroku上出错，heroku run rake db:migrate似乎不是解决方案。在本地主机上，一切都很完美，包括用于创建引脚的验证码验证。

以下是heroku日志的全部内容：

我不知道该怎么做。您可以在http://www.github.com/harrisongill/whatyoutheat找到此项目。非常感谢任何帮助。
答案 0 :(得分：1)
问题是您需要的迁移完全从您的仓库中丢失。我不确定您是否有本地副本，但似乎没有任何迁移在您的存储库中创建simple_captcha_data表。
在您的仓库中搜索Github上的'simple_captcha_data'，您会发现它只出现在您的db / schema.rb中。因此，要么您没有签入迁移文件，要么在本地运行并在某个时候将其删除。
答案 1 :(得分：0)
您的数据库看起来不完整。确保在使用应用程序之前正确部署了代码并运行了所有必要的迁移。
https://devcenter.heroku.com/articles/getting-started-with-rails3#rake-and-database-migrations
上述数据库迁移不会自动运行。如果你有 要运行的迁移，请务必在运行后运行heroku run rake
db:migrate部署。您可以在Rake命令上找到更多信息。
