Ruby-on-rails – Turn off transactional fixtures for one spec with RSpec 2

rspecrspec2ruby-on-railsruby-on-rails-3

How do I turn off transactional fixtures for only one spec (or Steak scenario) with RSpec 2?
I tried some things found on the web without any success.

This leads to an undefined method exception.

describe "MyClass without transactional fixtures" do
  self.use_transactional_fixtures = false
  ...
end

This simply does nothing (transactional fixture is still on):

describe "MyClass without transactional fixtures" do
  RSpec.configure do |config|
    config.use_transactional_fixtures = false
  end
  ...
end

What else could I try?

I usually add a helper like this:

def without_transactional_fixtures(&block)
  self.use_transactional_fixtures = false

  before(:all) do
    DatabaseCleaner.strategy = :truncation
  end

  yield

  after(:all) do
    DatabaseCleaner.strategy = :transaction
  end
end

Which lets me turn off transactional fixtures for a specific block in the specs:

describe "doing my thing" do
  without_transactional_fixtures do
    it "does something without transaction fixtures" do
      ...
    end
  end
end
