Django Rest Framework - Could not resolve URL for hyperlinked relationship using view name “user-detail”

Question

I am building a project in Django Rest Framework where users can login to view their wine cellar. My ModelViewSets were working just fine and all of a sudden I get this frus

Answer 1

Same Error, but different reason:

I define a custom user model, nothing new field:

from django.contrib.auth.models import (AbstractUser)
class CustomUser(AbstractUser):
    """
    custom user, reference below example
    https://github.com/jonathanchu/django-custom-user-example/blob/master/customuser/accounts/models.py

    # original User class has all I need
    # Just add __str__, not rewrite other field
    - id
    - username
    - password
    - email
    - is_active
    - date_joined
    - method, email_user
    """

    def __str__(self):
        return self.username

This is my view function:

from rest_framework import permissions
from rest_framework import viewsets
from .models import (CustomUser)
class UserViewSet(viewsets.ModelViewSet):
    permission_classes = (permissions.AllowAny,)
    serializer_class = UserSerializer

    def get_queryset(self):
        queryset = CustomUser.objects.filter(id=self.request.user.id)
        if self.request.user.is_superuser:
            queryset = CustomUser.objects.all()
        return queryset

Since I didn't give queryset directly in UserViewSet, I have to set base_name when I register this viewset. This is where my error message caused by urls.py file:

from myapp.views import (UserViewSet)
from rest_framework.routers import DefaultRouter
router = DefaultRouter()
router.register(r'users', UserViewSet, base_name='customuser')  # <--base_name needs to be 'customuser' instead of 'user'

You need a base_name same as your model name - customuser.
