Testing after_transition with Rspec & Rails -

i have 2 models: lessonbooking , customerrequests

once lessonbooking paid, associated customerrequests marked booked. note: lessonbooking not directly associated via id customers enter email when pay , email used check existing customer requests marked "booked" if found. here relevant code in lesson_booking.rb:

event :payment_received   transition :form_started => :paid end after_transition :form_started => :paid |booking|   email = booking.teaching_relationship.student.account.email   customer_request = customerrequest.find_by_email(email)   unless customer_request.nil?     customer_request.book   end end 

the customerrequest model has state machine has event "book" shown here:

event :book   transition [:new, :opened, :awaiting_response] => :booked end 

now incapable of getting spec passed tests transition of lessonbooking "form_started" "paid" , following transition of customerrequest "new" "booked".

here spec wrote:

context 'when there associated customer request'   before :each     @student = create(:student)     relationship = create(:teaching_relationship, student: @student)     @new_booking = create(:lesson_booking, teaching_relationship: relationship)     @customer_request = create(:customer_request, student: @student, email: @student.account.email )   end    "it changes state of customer request"     @new_booking.payment_received     expect(@customer_request.state).to eq 'booked'   end end 

end

my test fails following note:

expected: "booked" got: "new" 

i knew testing in general , appreciate help.
