Question

一直致力于使用NitrousIO为我的环境和Heroku for Deployment进行Ruby on Rails应用程序开发。对于我可以在Heroku上成功部署的一些模块，它工作正常，但对于某些模块，它说We're sorry, but something went wrong.

在将最新代码推送到heroku之后我已经完成了heroku run rake db:migrate之类的所有步骤但是没有成功但是在NitrousIO上，一切都很完美

现在有什么方法可以在Heroku上重置我的数据库，以便它可以在没有问题的情况下适用于所有模块。请指导/指出一步一步的程序
是否只有db reset选项才能开始，或者我们是否有任何中间解决方案让我摆脱这种情况？

这些是带有heroku logs -n 250

Answer 1

根据屏幕截图中的“缺少要链接的主机”错误消息，您似乎缺少某些配置。 link_to方法需要知道用于生成给定链接的完整URL的主机名。您可以在每个环境文件中对此进行配置，在这种情况下，您需要向config/environments/production.rb添加类似的内容：

config.action_mailer.default_url_options = { :host => "enterpriseape-ramakballa.herokuapp.com" }
