Within my integration tests, it appears that after using the login() method of django.test.client.Client the context dict consists only of:

[{'False': False, 'None': None, 'True': True}, {}, {}].

If I remove the use of login(), then the request dict consists of:

[{'False': False, 'None': None, 'True': True}, {'object': <User: te...@test.com>, 'user': <User: te...@test.com>, u'view': <accounts.views.AccountDetail object at 0x13bedd0>}, {u'csrf_token': <django.utils.functional.__proxy__ object at 0x1430090>}, {'perms': <django.contrib.auth.context_processors.PermWrapper object at 0x14301d0>, 'user': <django.utils.functional.SimpleLazyObject object at 0x13be390>}, {}, {u'MEDIA_URL': '/media/'}, {'messages': <django.contrib.messages.storage.fallback.FallbackStorage object at 0x1393c10>}, {u'request': <WSGIRequest

path:/accounts/,

GET:<QueryDict: {}>,

POST:<QueryDict: {}>,

COOKIES:{'sessionid': 'q27przqeidsnfykuufu7m6lo7nw606qw'},

I noticed the problem when a template tag was trying to access context["request"].path and a KeyError was raised after using login. Both outputs above are the result of printing the context var from within the render() method of a template tag. Any help would be greatly appreciated, as I'm a bit stumped.

Thanks,

Below are some snippets involved in generating the error. The 'test_get_unauthenticated' works as expected, but 'test_get_ok' fails while rendering the template response and calling the menu tag of django-menu (full module: https://github.com/rossp/django-menu/blob/master/menu/templatetags/menubuilder.py).

integration_tests.py

class IntegrationTestCase(TestCase):

def setUp(self):

self.client = Client()

self.test_domain = "http://testserver"

class AccountDetail(IntegrationTestCase):

def test_get_unauthenticated(self):

"""302"""

destination = reverse("account_detail")

response = self.client.get(destination)

self.assertRedirects(response, reverse("login") + "?next=" + destination)

def test_get_ok(self):

"""200"""

user = UserFactory.create()

self.client.login(username=user.username, password="testPass")

response = self.client.get(reverse("account_detail"))

self.assertEqual(response.status_code, 200)

self.assertTemplateUsed(response, "accounts/account_detail.html")

menubuilder.py

class MenuObject(template.Node):

def __init__(self, menu_name):

self.menu_name = menu_name

def render(self, context):

current_path = context['request'].path

user = context['request'].user

context['menuitems'] = get_items(self.menu_name, current_path, user)

return ''
