Why is DatabaseCleaner causing this RSpec controller test to fail? - ruby-on-rails

Question

I am attempting to setup DatabaseCleaner with RSpec to make sure that I can properly cleanup any test objects that I have created. If I don't use DatabaseCleaner, then the following test passes.
However, when I add the DatabaseCleaner code to my spec_helper.rb file, the test fails as outlined below.
include AuthHelper
describe BulkJobsController do
describe 'GET /bulk_jobs/:id' do
context 'with valid user' do
before do
login_as('someuser')
end
context 'and a job' do
before do
#job = create(:bulk_job_close_cases)
puts "Test - Bulk Job Count: #{BulkJob.count}" # This is always 1
get :show, id: #job.id, format: 'json'
end
it 'is valid' do
response.status.should eq(200)
end
end
end
end
end
Here is the controller:
class BulkJobsController < ApiController
def show
puts "Controller - Bulk Job Count: #{BulkJob.count}" # This is 1 without DC and 0 with DC
#job = BulkJob.find(params[:id])
respond_with #job
end
end
Here is the relevant portion of my spec/spec_helper.rb file:
####################
# Database Cleanup #
####################
require 'database_cleaner'
config.use_transactional_fixtures = false
config.after(:suite) do
ActiveRecord::Base.connection.execute("DEALLOCATE ALL")
end
config.around(:each) do |example|
DatabaseCleaner.strategy = :transaction
DatabaseCleaner.start
example.run
DatabaseCleaner.clean
end
Oddly, removing the DatabaseCleaner.clean statement doesn't actually make the test pass either; however, removing the DatabaseCleaner.start code does make the test pass.
The test is failing because the controller can't find a BulkJob with the proper ID. If I print out the counts of the objects, inside the test the number of BulkJobs is 1, but inside the controller, it's 0. When the test passes, obviously, the number is 1 in both spots.
I haven't included Capybara or Selenium, so as I understand it, rspec should be using rack-test to run this example.
Is there something wrong with my configuration/test? Is DatabaseCleaner cleaning too early?
Here is the failing test:

1) BulkJobsController GET /bulk_jobs/:id with valid user and a job is valid
