问题
My site is currently dead therefore I can't explain how urgent for me this is.
Situation: A few days ago I received an e-mail from Heroku "ACTION REQUIRED: Rails Security Vulnerability " advising me to update rails to version '3.2.11'. After I followed all the steps in the e-mail I tried to open my web site. I was extremely surprised when I saw that I can't open my site. My site is made with RefineryCMS.
Is it possible, using git, to restore my site to the previous point in time when everything was working great?
When I run the site locally I get the following error:
ActiveRecord::RecordNotFound in Refinery::PagesController#home
Couldn't find Refinery::Page with id=torte-za-rodendan

Yep, we all got that email from Heroku.
Since your site was versioned with git before, you can undo the last commit by following these steps.
However, I am not sure whether you really need to do the above. You just need to make sure that your heroku app runs on rails 3.2.11 - it is a pretty serious security issue, maybe heroku even blocks sites that aren't upgraded quickly enough.
Follow these steps:
- Run your tests and make sure everything works
- Open up a new branch through git (
git checkout -b new_rails) - Change Rails 3.2.11 in your Gemfile
- Change RAILS_GEM_VERSION to '3.2.11' in environment.rb
- Run
bundle update rails - Run the tests and see if everything still works
- If not, reverse back to the old branch by doing
git checkout master; optionally delete the new branch by doinggit branch -D new_rails
Doing it only on the new branch ensures nothing breaks.
If you still get errors afterwards, please tell us what's in heroku's log.
