ruby-on-rails - ActiveRecord::StatementInvalid(找不到表)

Question

我在 DigitalOcean 上有一个 Rails 应用程序。我正在使用舒适的墨西哥沙发 CMS。我添加了 gem 并运行 railsgenerate comfy:cms 和 rake db:migrate 但当我导航到 example.com/admin 时，我收到 500 错误，并且我的应用程序无法找到必要的表格。这是我在日志中收到的错误。

ActiveRecord::StatementInvalid (Could not find table 'comfy_cms_sites'):

对我来说奇怪的是，当我运行 rails c 和 ActiveRecord::Base.connection.tables 时，表格会显示，并且“comfy_cms_sites”就在那里。

确保您已在生产数据库上运行迁移

rake db:migrate RAILS_ENV=production
