Django Test | How to pass a a dictionary containing a dictionary value through clients.post

Question

I have a dictionary A that contains a single value that is also a dictionary B

B = {"k1": "v1", "k2": "v2", "k3": "v3",}
A = {"User": B}

This type of dictionary is used in one of my views function

def views_function(request):
   # request.data is a dictionary containing a single value that is also a dictionary. Just like A

I'm trying to write a unit test for views_function from django.test.TestCase.

from django.test import TestCase

class test_cases(TestCase):
    
    def setUp(self):
        self.B = {"k1": "v1", "k2": "v2", "k3": "v3",}
        self.A = {"User": self.B}
        self.url = reverse("views_function_url")

    def test_views_function(self):
        response = self.client.post(url, self.A, format="json")

But clients.post seems unable to take A as an input. When I print A inside test_views_function it shows the proper dictionary.

def test_views_function(self):
    B = {"k1": "v1", "k2": "v2", "k3": "v3",}
    A = {"User": B}
    print(A)  # {"User": {"k1": "v1", "k2": "v2", "k3": "v3"}}
    response = self.client.post(url, A, format="json")

But when I add a print statement to views_function for some reason only the last key of B is there

def views_function(request):
   print(request.data.dict()) # {'User': 'k3'}

Solution was simple, I had the wrong argument by accident. It's content_type="application/json" not format="json" in self.client.post()
