Upgrading to Rails 4.0
I’m busy upgrading several apps to Rails 4.0. As is to be expected, there are a few gotchas here and there. Most are documented somewhere… deep in a changelog… mixed in with dozens of other things that probably won’t bite you.
I’ve been posting some of my notes along the journey. This particular post will serve as a central reference point, a table of contents of sorts, and will just contain links to other posts. I’ll try to keep it updated as I add new posts.
See the official Ruby on Rails article to start.
Models and datastores
- Missing assets - whole directories (or gems) of assets missing
