Can't access self.request.user when overriding FilterSet.qs

I have written code for a filter that takes into account some fields of a given patient (name, age and id). The users of the website will be doctors, and I want only patients of the current logged in doctor to come up in the search. After reading the docs and trying to do so in many different ways, I have accomplished nothing.

It seems the best method is to override the FilterSet.qs function and so I did, similarly to what is present in the documentation. However, when I try to access self.request.user it comes back as none, even though there is a user currently logged in.

I am new to Django and still trying to figure things out. Any help is highly appreciated. I believe I have pasted in all that is relevant, but I am sorry in advance if something is missing.

import django_filters
from .models import Patient, Teams
from django import forms
from django.contrib.auth.models import User


class PatientFilter(django_filters.FilterSet):

    id = django_filters.NumberFilter(widget=forms.NumberInput(attrs={ 'min': '1'}))
    age = django_filters.NumberFilter(widget=forms.NumberInput(attrs={ 'min': '0'}))

    class Meta:
        model = Patient

        fields = {
            'first_name' : ['icontains'],
            'age' : ['exact'],
            'id' : ['exact']

        }

    @property
    def qs(self):
        parent = super().qs
        author = getattr(self.request, 'user', None)
        print('Author')
        print(self.request)

        return parent.filter(owner=author)

In your case, you are trying to filter the base queryset with logged-in user. For that, you don't need the filter set class, just override the get_queryset(...) method

class UserPatientListView(FilterView, ListView):
    model = Patient
    template_name = 'bcctapp/user_patients.html'
    context_object_name = 'patients'
    paginate_by = 2
    filterset_class = PatientFilter

    def get_queryset(self):
        queryset = super().get_queryset().filter(owner=self.request.user)
        return queryset

    def get_context_data(self, **kwargs):
        context = super().get_context_data(**kwargs)
        context['filter'] = PatientFilter(self.request.GET, queryset=self.get_queryset())
        context['number_results'] = context['filter'].qs.count()
        return context
