Wie django Serializer in Unit-Test

Question

Klasse ProcessDocRequestTestCase (BxApiTestCase) verwenden: username = 'hr'

def test_email_sent_on_creation(self): 
    r = r0 = self.r('post', 201, '/api/processes', %post_data%) 

    requestor_superior_id = r0.data['extra']['next_employees'][0] 
    superior_emp = Employee.objects.get(pk=requestor_superior_id) 
    employee_serializer = EmployeeSerializer(superior_emp, context={'request': r}) 
    employee_serializer.data 

die letzte Zeile stürzt mit diesem Fehler:

Traceback (most recent call last): File "/my_proj/bx/process/tests.py", line 81, in test_email_sent_on_creation employee_serializer.data File "/my_proj/venv/local/lib/python2.7/site-packages/rest_framework/serializers.py", line 503, in data ret = super(Serializer, self).data File "/my_proj/venv/local/lib/python2.7/site-packages/rest_framework/serializers.py", line 239, in data self._data = self.to_representation(self.instance) File "/my_proj/venv/local/lib/python2.7/site-packages/rest_framework/serializers.py", line 472, in to_representation ret[field.field_name] = field.to_representation(attribute) File "/my_proj/venv/local/lib/python2.7/site-packages/rest_framework/relations.py", line 340, in to_representation url = self.get_url(value, self.view_name, request, format) File "/my_proj/venv/local/lib/python2.7/site-packages/rest_framework/relations.py", line 277, in get_url return self.reverse(view_name, kwargs=kwargs, request=request, format=format) File "/my_proj/venv/local/lib/python2.7/site-packages/rest_framework/reverse.py", line 50, in reverse url = _reverse(viewname, args, kwargs, request, format, **extra) File "/my_proj/venv/local/lib/python2.7/site-packages/rest_framework/reverse.py", line 65, in _reverse return request.build_absolute_uri(url) AttributeError: 'Response' object has no attribute 'build_absolute_uri'

Wie kann ich das tun ?

als Referenz, ist meine r Methode, wie so definiert:

from rest_framework.test import APIClient 
.. 

def setUp(self): 
    self.refreshTestData() 
    self.c = APIClient() 
    if getattr(self, 'username', None): 
     self.login(self.username, self.password) 

def r(self, method, status_code, url, data=None, *args, **kwargs): 
    kwargs['data'] = data 
    kwargs['format'] = kwargs.get('format', 'json') 
    r = getattr(self.c, method)(url, *args, **kwargs) 
    self.assertEqual(r.status_code, status_code, 
     'Expected status %d, got %d.\n%s\n%s' % (
      status_code, r.status_code, url, pformat(getattr(r, 'data', None)))) 
    return r 

Answer 1

dies zu tun, ich musste einfach auf "Mock" eine Anforderung APIRequestFactory verwenden.

Also schrieb ich diese Methode auch:

# call response 
def r(self, method, status_code, url, data=None, *args, **kwargs): 
    kwargs['data'] = data 
    kwargs['format'] = kwargs.get('format', 'json') 


    r = getattr(self.c, method)(url, *args, **kwargs) 
    self.assertEqual(r.status_code, status_code, 
     'Expected status %d, got %d.\n%s\n%s' % (
      status_code, r.status_code, url, pformat(getattr(r, 'data', None)))) 
    return r 

# return both request and response 
def rq(self, method, status_code, url, data=None, *args, **kwargs): 
    kwargs['data'] = data 
    kwargs['format'] = kwargs.get('format', 'json') 

    request = getattr(self.f, method)(url, *args, **kwargs) 

    return request, self.r(method, status_code, url, data) 

und dann das ist, wie ich es genannt:

rq, rs = self.rq('post', 201, data) 
    rs0 = rs 

    requestor_superior_id = rs0.data['extra']['next_employees'][0] 
    superior_emp = Employee.objects.get(pk=requestor_superior_id) 

    self.attach_user_to_request(rq, self.username) 

    employee_serializer = EmployeeSerializer(superior_emp, context={'request': rq}) 
    employee_serializer.data # works 

Anmerkung: ich hatte auch „anhängen“ einen Benutzer auf die Anforderung wie so

def attach_user_to_request(self, request, username, password=None): 
    try: 
     user = User.objects.get(email=username+'@test.test') 
    except User.DoesNotExist: 
     raise Exception('No Such User') 
    if not user.check_password(None, password or 'test'): 
     raise Exception('Bad Password') 
    user.backend = settings.AUTHENTICATION_BACKENDS[0] 
    request.user = user 
    return True
