Rspec and Devise: Could not find a valid mapping for #<User

[99miles]

using RSpec and Devise, I'm getting a mapping error.

1) BusinessesController GET index sets @new_vacation
Failure/Error: sign_in @user
RuntimeError:
Could not find a valid mapping for #<User id: 8009, email:
"pers...@cycle7.com", encrypted_password: "$2a

# ./spec/controllers/businesses_controller_spec.rb:10:in

It looks like the answer might be in here
http://stackoverflow.com/questions/5966971/rspec-tests-with-devise-could-not-find-valid-mapping
but I can't get it.

Any ideas, I'm really stumped! Thanks.
