ActiveRecord::StatementInvalid（找不到表）

Question

我在 DigitalOcean 上有一個 Rails 應用程序。 我正在使用舒適的墨西哥沙發 CMS。 我添加了 gem 並運行rails generate comfy:cms和rake db:migrate但是當我導航到 example.com/admin 時，出現 500 錯誤並且我的應用程序無法找到必要的表。 這是我在日志中得到的錯誤。

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

對我來說似乎很奇怪的是，當我運行rails c和ActiveRecord::Base.connection.tables ，表格會出現並且“comfy_cms_sites”在那里。

確保您已在生產數據庫上運行遷移

rake db:migrate RAILS_ENV=production
