app view

from rest_framework.views import Response, APIView


class ExampleView(APIView):

    return Response({"message": "hello world"})

test app

from django.urls import reverse
from rest_framework.test import APISimpleTestCase


class TestUser(APISimpleTestCase):

def setUp(self):

    self.path1 = reverse('v1:users:home')

def test_user_path(self):
    print(self.path1)

what is wrong with this code? why it return django.urls.exceptions.NoReverseMatch: 'users' is not a registered namespace inside 'v1'

CodePudding user response：

Try the following:

reverse('v1:home')

You have already changed the namespace of users to v1. Since users is not a URL path name in the app's urls.py, you get an error.
