After switching branches, Rails throws undefined method inside of a helper module

Not sure if I could reliably reproduce this, but sometimes when I switch branches in development all requests start throwing an undefined method error inside of a helper. The method is present on both branches. I am using global helpers (helper :all).

To fix the issue, I go into the helper file and save any change. Usually I just add a new line to the end of it. After saving, it works fine. Seems like a caching issue.

Has anyone else seen this and resolved it? I am on Rails 4.2.1. As far as I know this only happens in development mode.

Since you are using Rails 4.2, spring has probably cached the code from the old branch. After switching to the new branch remember to run:

spring stop

Spring will restart itself the next time you run the server, tests, or other Rails commands.
