Test Cases For PUT in DJANGO REST and mongoengine

I am using DJango 1.8.3 and mongo as database using mongoengine for developing rest based API.

My models.py file is 

class Client(Document):
    client_name = StringField(max_length=50)
    client_email = EmailField()
    city = StringField(max_length=50)
    country = StringField(max_length=200, verbose_name="Country")

Serializers.py class ClientSerializer(DocumentSerializer):

    class Meta:
        model = Client
        depth = 1

views.py

class ClientDetails(generics.RetrieveUpdateDestroyAPIView):
    serializer_class = ClientSerializer
    queryset = Client.objects.all()

class ClientList(generics.ListCreateAPIView):
    serializer_class = ClientSerializer
    queryset = Client.objects.all()

urls.py

urlpatterns = [
url(r'^client/$', views.ClientList.as_view(), name='client'),
url(r'^client/(?P<id>[\w]{24})/$', views.ClientDetails.as_view(),
    name='client_details'),
]

test.py

def test_get_client(self):
    """
    Ensure we get existing clients from mongo database.
    """
    url = '/client_management/client/'
    factory = APIRequestFactory()
    user = User.objects.get(username='jacob')
    view = views.ClientList.as_view()

    # Make an authenticated request to the view...
    request = factory.get(url)
    force_authenticate(request, user=user)
    response = view(request)
    self.assertEqual(response.status_code, 200)

def test_delete_client(self):
    """
    Ensure we can delete new clients in mongo database.
    """
    url = '/client_management/client/'
    data = {'client_name'='XX'}
    factory = APIRequestFactory()
    user = User.objects.get(username='jacob')
    view = views.ClientList.as_view()

    # Make an authenticated request to the view...
    request = factory.post(url, data=data,)
    force_authenticate(request, user=user)
    response = view(request)
    ##self.assertEqual(response.status_code, status.HTTP_201_CREATED)

    g_id = response.data['id']
    urls = '/client_management/client/?id=' + g_id
    ## even tried
    ## urls = '/client_management/client/ + g_id + /
    data['id'] = g_id
    #data['client_name'] = 'MAA'
    view = views.ClientDetails.as_view()
    request = factory.delete(urls)
    ## tried this also
    ## request = factory.delete('/client_management/client/', id=g_id)
    print request
    force_authenticate(request, user=user)
    response = view(request)
    self.assertEqual(response.status_code, 201)

which is working as expected. GET AND POST test cases are working fine

When I am writing Test cases for PUT, DELETE

I am getting the error

Expected view ClientDetails to be called with a URL keyword argument named "id".
Fix your URL conf, or set the `.lookup_field` attribute on the view correctly

From Error It is clear it is expecting ID I tried passing client ID in url also as a seprate parameter in request.

But error is still same, don't know how to pass id in this case any help is appreciated.

Advance thanks for help

Finally Figured it out

def test_delete_client(self):
    """
    Ensure we can delete new clients in mongo database.
    """
    url = '/client_management/client/'
    data = {'client_name'='XX'}
    factory = APIRequestFactory()
    user = User.objects.get(username='jacob')
    view = views.ClientList.as_view()

    # Make an authenticated request to the view...
    request = factory.post(url, data=data,)
    force_authenticate(request, user=user)
    response = view(request)
    ##self.assertEqual(response.status_code, status.HTTP_201_CREATED)

    g_id = response.data['id']
    urls = '/client_management/client/?id=' + g_id
    ## even tried
    ## urls = '/client_management/client/ + g_id + /
    data['id'] = g_id
    #data['client_name'] = 'MAA'
    view = views.ClientDetails.as_view()
    request = factory.delete(urls)
    ## tried this also
    ## request = factory.delete('/client_management/client/')
    print request
    force_authenticate(request, user=user)
    response = view(request, id=str(g_id))
    self.assertEqual(response.status_code, 201)

You have to send ID when calling view(request) as response = view(request, id=str(g_id)).

The docs seems to indicate that the default lookup_field is pk and not id. I would try to either change the url pattern to

...
url(r'^client/(?P<pk>[\w]{24})/$', views.ClientDetails.as_view(),
    name='client_details'),
...

or add a lookup_field attribute to your view

class ClientDetails(generics.RetrieveUpdateDestroyAPIView):
    serializer_class = ClientSerializer
    queryset = Client.objects.all()
    lookup_field = ('id',) # Note the parenthesis, they are needed so the object is a tuple

Change your code and reposting

urls.py

urlpatterns = [
    url(r'^client/(?P<id>[\w]{24})/$', views.ClientDetails.as_view(),
    name='client_details'),
]

test.py In the url you are passing the pk value. In the test case also you need to pass the pk value of id. In the above code i absorbed that you passing id as query-parameter so i'm passing it as pk.

def test_delete_client(self):
    """
    Ensure we can delete new clients in mongo database.
    """
    g_id = response.data['id']
    urls = '/client_management/client/' + str(g_id) + '/'
    view = views.ClientDetails.as_view()
