If you’re using Devise and rspec on Rails 3, and you want to override a controller, and you end up with an error that makes no sense whatsoever:
“Undefined method ‘name’ for nil:NilClass”, well then, you probably want to add the following line to your tests:
@request.env["devise.mapping"] = Devise.mappings[:admin]
Yeah… That took me way longer than expected.
On a COMPLETELY UNRELATED SIDE NOTE, pry is pretty cool when you end up having to step through code…
