Disable cache in Django REST Framework testing

I am looking for a way to clear the cache after a request. In the same test, I am testing the results with a normal user request, and staff user request. Here's the important part of my test (from an APITestCase class)

# REGULAR USER

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

response = self.client.get(url)

# HTTP_200_OK
self.assertEqual(response.status_code, status.HTTP_200_OK)

# Only 1 user can be returned
self.assertEqual(len(response.data), 1)

# User returned is current user
self.assertEqual(response.data[0]['username'], 'user')



# STAFF USER

cache.clear() # <- this does not work

# Creating a staff user
staff_user = User(username='staff_user', password=self.password, is_staff=True)
staff_user.set_password(self.password)
staff_user.save()

self.client.logout()
self.client.login(username=staff_user.username, password=self.password)

response = self.client.get(url)

# HTTP_200_OK
self.assertEqual(response.status_code, status.HTTP_200_OK)
print response.data

# Superuser cannot be contained in list
self.assertEqual(len(response.data), 3)

So, in the second response I am getting the same results, although they should be different
