FAIL: test_create_author_multipart (testapp.tests.TestEndpoint)
Exercise multipart/form-data POST
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/home/cleber/code/third-party/django-restless/testproject/testapp/tests.py", line 346, in test_create_author_multipart
    self.assertEqual(r.status_code, 201, r.content)
AssertionError: 400 != 201 : b'{"error": "invalid author data", "details": {"name": ["This field is required."]}}'

I made a slight modification on asserEqual so it could print r.content. Aparently, although name is indeed being present on the payload (see below), it's not being recognized somewhere.

The test:

    def test_create_author_multipart(self):    
        """Exercise multipart/form-data POST"""    
    
        r = self.client.post('author_list', data={    
            'name': 'New User',    
        })  # multipart/form-data is default in test client    
        self.assertEqual(r.status_code, 201, r.content)    
        self.assertEqual(r.json['name'], 'New User')    
        self.assertEqual(r.json['name'],    
                         Author.objects.get(id=r.json['id']).name)

I proposed a solution. It seems the issue is in Django itself:
django/django#8142

(The weird thing is: am I the only one getting this error?)

Hi @cleberzavadniak, Django 1.10 introduces content_type attribute on the HttpRequest thus clashing with content_type we used. Django's attribute can be normally used from restless, but ours doesn't behave exactly as Django expects, thus the errors.

I had a fix sitting in the branch waiting for validation since Dec, but noticed I hadn't merged it. I have now (see #28 and #27 for related bug report). Please let me know if this fixes your problem.

Man, you can't forget that kind of thing! Haha!
Thanks.
