ipoval / yammer_dot_com_rails_4_upgrade.txt
Last active May 31, 2016 23:19
Rails 4 upgrade
Upgrading Rails 3.2.12.2 to Rails 4.1.15
git fetch origin rails_4
git checkout -b rails_4 FETCH_HEAD
rails_4 branch is rebased often, so git branch -D rails_4; git pull origin rails_4
MAIN AREAS OF WORK
- everything that has `# FIXME: rails4` comment line in this PR needs to be fixed for `rails_4` branch
- if possible the fix should be applied in `master` branch first, and `rails_4` branch rebased on top of `master`
