Django REST - How do I correctly configure URLs lookup_field?

I've made a few django projects and am now experimenting with the rest framework. I'm trying to configure my urls such that url /testuser/ will take you to the profile page of user with username 'testuser'. Pretty simple task that I can manage in regular django using slug_field but I guess I'm not quite understanding how to correctly configure REST urls. Any help appreciated. Code below.

FYI, as you will see below, I am using a CustomUser model, linked to a Profile model by OneToOneField. The username is stored in the CustomUser model. However, the profile page will be populated using ProfileSerializer.

I believe the issue might be the way I am accessing the 'username' from the related model, CustomUser - but I could be wrong (likely, lol). Anyone have any idea?

My current code throws the error:

Expected view ProfileView to be called with a URL keyword argument named "username". Fix your URL conf, or set the .lookup_field attribute on the view correctly.

users.models

class CustomUser(AbstractBaseUser):
    username = models.CharField(
        verbose_name='username',
        max_length=40,
        unique=True,
    )
    ...

profiles.models

class Profile(models.Model):
    user = models.OneToOneField(
        settings.AUTH_USER_MODEL,
        on_delete=models.CASCADE,
        related_name='profile'
    )
    ...

profiles.serializers

class ProfileSerializer(serializers.ModelSerializer):
    username = serializers.CharField(read_only=True, source="user.username")

    class Meta:
        fields = ('username', 'display_name', 'profile_pic',
                  'bio', 'following', 'modified', 'est', )
        model = Profile
        lookup_field = 'username'

profiles.views

class ProfileView(generics.RetrieveUpdateAPIView):
    queryset = Profile.objects.all()
    serializer_class = ProfileSerializer
    lookup_field = 'username'

profiles.urls

urlpatterns = [
    path('<str:slug>/', PostDetail.as_view(), name='self_profile'),
]

Thanks for your help.

Your view is expecting username URL parameter, but it receives slug. You can either change your URL to pass on username instead of slug, or set lookup_url_kwarg to slug on your view to fix that situation.
