Solve the following python programming problem given the following code:
@ pytest.mark.django_db 
def test_signal_when_user_logout_slo(monkeypatch, django_user_model, settings) : 
    data = { 
        'logoutRequest' : '<samlp:LogoutRequest xmlns:samlp="urn:oasis:names:tc:SAML:2.0:protocol"><samlp:SessionIndex>fake-ticket</samlp:SessionIndex></samlp:LogoutRequest>', 
} 
    settings.CAS_VERSION = 'CAS_2_SAML_1_0' 
    factory = RequestFactory () 
    request = factory.post ('/login', data) 
    request.session = { 
        
} 
    user = django_user_model.objects.create_user ('test@example.com', '') 
    assert (user is not None) 
    session = SessionStore () 
    session ['fake_session_key'] = 'fake-session_value' 
    session.save () 
    assert (SessionStore (session_key = session.session_key) is not None) 
    session_ticket = SessionTicket.objects.create (session_key = session_ticket.session_key, ticket = 'fake-ticket') 
    callback_values = { 
        
} 
    @ receiver (cas_user_logout) 
    def callback(sender, session, **kwargs) : 
        callback_values.update (kwargs) 
        callback_values ['session'] = dict (session) 
response = login (request) 
    assert ('user' in callback_values) 
    assert ('session' in callback_values) 
    assert (callback_values ['session'].get ('fake_session_key') == 'fake-session_value') 
    assert ('ticket' in callback_values) 
    assert (callback_values ['ticket'] == 'fake-ticket') 

    
    

    Fix the buggy line: session_ticket = SessionTicket.objects.create (session_key = session_ticket.session_key, ticket = 'fake-ticket')

#Here is Python code to fix the buggy line: session_ticket = SessionTicket.

session_ticket = SessionTicket.objects.create (session_key = session.session_key, ticket = 'fake-ticket')
