How to update existing model instance in Django Rest Framework

The Model

class Artist(models.Model):
    user = models.ForeignKey(User, on_delete=models.CASCADE, null=True)

    def __str__(self):
        return self.name

The View

from rest_framework import generics

class RetrieveArtistUserView(generics.RetrieveUpdateAPIView):
    queryset = Artist.objects.all()
    serializer_class = RetrieveArtistMusicSerializer
    permission_classes = [HasAPIKey | IsAuthenticated]
    lookup_field = 'u_email__email'

The Route

urlpatterns = [
    path("", include(router.urls)),
    path("retrieve_artist_user/<u_email__email>", RetrieveArtistUserView.as_view(), name="retrieve_artist_user"),
    // YOUR OTHER ROUTES
] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

The Query (Postman)

{
  "name": "Cheri Lyn"
}

The Result

{
    "name": "Cheri Lyn",
    "other_things": []
}
