I've been trying to test a very simple action on a controller with this setup:

rspec 1.3.0
ruby 1.8.7 (2009-06-12 patchlevel 174) [universal-darwin10.0]
Rails 2.3.8
devise 1.0.8

And this is the test:

before :each do
  @member = Factory.create(:member)
  sign_in @member
  @person = Person.new
end

it "should render form for a new person on GET people#new" do
  current_member.should_receive(:build_person).and_return(@person)

  get :new

  assigns[:person].should == @person
  response.should be_success
  response.should render_template("new")
end

This test creates a user, which is stored in the database with a correct password. Running this test results in this error:

NoMethodError in 'PeopleController Methods should render form for a new person on GET people#new'
You have a nil object when you didn't expect it!
You might have expected an instance of ActiveRecord::Base.
The error occurred while evaluating nil.[]=

I wen to /Library/Ruby/Gems/1.8/gems/warden-0.10.4/lib/warden/session_serializer.rb and I changed the file in order to print out some values:

def store(user, scope)
return unless user
p scope
p key_for(scope)
p user
p serialize(user)
p session
session[key_for(scope)] = serialize(user)
end

When running the test again I get:

:member

"warden.user.member.key"

Member id: 1, email: "member2@hv_club.com", encrypted_password: "c79e5e4790643b284002bf6ad8045f53ff900afc", password_salt: "Rim9LiyKARU1SHQCWIb0", confirmation_token: nil, confirmed_at: nil, confirmation_sent_at: nil, reset_password_token: nil, remember_token: nil, remember_created_at: nil, sign_in_count: 0, current_sign_in_at: nil, last_sign_in_at: nil, current_sign_in_ip: nil, last_sign_in_ip: nil, created_at: "2010-07-09 16:45:44", updated_at: "2010-07-09 16:45:44"

nil

So it seems session is not initialized. Any ideas on how to fix this?

Thanks.
