AASM gem: How to stub or config :no_direct_assignment to false when make rspec on rails?

Hi all,

I am newbie AASM. I just tried to use AASM on my project.
I have a problem: at Model

class Job
include AASM

aasm :no_direct_assignment => true do
state :sleeping, :initial => true
state :running
state :cleaning
event :run do
transitions :from => :sleeping, :to => :running
end
event :clean do
transitions :from => :running, :to => :cleaning
end
event :sleep do
transitions :from => [:running, :cleaning], :to => :sleeping
end
end
end

And on rspec unit test


describe ‘#clean!’ do
before do
AASM::Configuration.stub(:no_direct_assignment).and_return(false)
end
describe ‘Job clearning cancel’ do
let(:job) { FactoryGirl.create(:job, aasm_status: ‘running’) }
context “when status is ‘running’” do
it “should update to cleaning” do
job.clean!
job.reload
job.aasm_status.should eql ‘cleaning’
end
end
end
end

When i run rspec i got error:

Failure/Error: let(:job) { FactoryGirl.create(:job, aasm_status:
‘running’) }
AASM::NoDirectAssignmentError: direct assignment of AASM column has
been disabled (see AASM configuration for this class)

Please share me any idea to make pass unit test.
How can i stub :no_direct_assignment right?
