Devise, RSpec and Webrat

My app is builded with rails 2.3.12, rspec-rails 1.3.2, webrat 0.7.3.

My spec_helper.rb

ENV[“RAILS_ENV”] ||= ‘test’
require
File.expand_path(File.join(File.dirname(FILE),’…’,‘config’,‘environment’))
require ‘spec/autorun’
require ‘spec/rails’
require ‘webrat’

Dir[File.expand_path(File.join(File.dirname(FILE),‘support’,’**’,’*.rb’))].each
{|f| require f}

Webrat.configure do |config|
config.mode = :rails
config.open_error_files = false # prevents webrat from opening the
browser
end

Uncomment the next line to use webrat’s matchers

require ‘webrat/integrations/rspec-rails’

Spec::Runner.configure do |config|
config.use_transactional_fixtures = true
config.use_instantiated_fixtures = false
config.fixture_path = RAILS_ROOT + ‘/spec/fixtures/’

include Webrat::Methods
#config.include Webrat::Matchers, :type => :views

end

My spec:
require ‘spec_helper’

describe “Campaign” do

describe “in first step” do
before(:each) do
@user = Factory(:user)
@campaign = Factory(:campaign, :owner => @user)
end

it "should have an owner" do
  @campaign.owner.should == @user
end

it "testing request" do
  visit "/"
end

end
end

I get:

ActionView::TemplateError in ‘Campaign in first step should have an
owner’
