django test client.put doesn't have data - django

Question

I am trying to test django view with REST framework.
It starts like this.
class MoveViewSet(viewsets.ModelViewSet):
serializer_class = FamilySerializer
queryset = Family.objects.all()
http_method_names = ['put']
def update(self, request, pk=None):
user = request.mobile_user
...
family_id = request.POST.get('family_id', None)
...
in test.py I make a request like this.
data = dict(
join_type='join',
family_id=target_family.id,
)
# also tried data = { ... }
header = {
'Authorization': user.api_key,
...
}
client = Client()
response = client.put(url, data=data, content_type='x-www-form-urlencoded', **header)
### What I've tried ###
# response = client.put(url, data=data, **header)
# response = self.client.put(url, data=data, **header)
# response = client.put(url, data=data, content_type='application/json', **header)
but in view, request.POST.get('paramname', 'default') makes error. request.POST has empty parameter set and of course, request.PUT is None.
I checked middleware but neither could I find params there.
Also I've tried this in middleware's process_request.
def process_request(self, request):
if request.method == "PUT" and request.content_type != "application/json":
if hasattr(request, '_post'):
del request._post
del request._files
try:
request.method = "POST"
request._load_post_and_files()
request.method = "PUT"
except AttributeError as e:
request.META['REQUEST_METHOD'] = 'POST'
request._load_post_and_files()
request.META['REQUEST_METHOD'] = 'PUT'
request.PUT = request.POST
It gives me this error.
AttributeError: 'WSGIRequest' object has no attribute 'content_type'
If I send client.post() with data, request.POST has data, but put doesn't.
How could I test client.put() with parameters?

request's content_type attribute has been added in Django 1.10. Since you are using Django 1.9 you cannot use this attribute. You can chec request.META.get('HTTP_ACCEPT') solution as mentioned here or update Django.
