'WSGIRequest' object has no attribute 'CustomUser'

Question

I want to create a patient system. User can add patients but I want to users can see only their patients. I used

patient_list = newPatients.objects.filter(current_user.id)

`but I get an error. How can I fixed it?

settings.py

    MIDDLEWARE = [
    'django.middleware.security.SecurityMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
]

views.py

@login_required
def patient_list(request):

    current_user = request.CustomUser
    patient_list = newPatients.objects.filter(current_user.id)
    query = request.GET.get('q')
    if query:
        patient_list = patient_list.filter(

            Q(first_name__icontains = query) |
            Q(last_name__icontains = query)  |
            Q(dept__icontains = query)  |
            Q(address__icontains = query)  |
            Q(phone__icontains = query)  |
            Q(notes__icontains = query))

    paginator = Paginator(patient_list, 5)  # Show 5 contacts per page

    page = request.GET.get('page')
    try:
        patients = paginator.page(page)
    except PageNotAnInteger:
        # If page is not an integer, deliver first page.
        patients = paginator.page(1)
    except EmptyPage:
        # If page is out of range (e.g. 9999), deliver last page of results.
        patients = paginator.page(paginator.num_pages)

    return render(request, "patients.html", {'patients':patients})

Answer 1

In Django, you should always use request.user to get the logged-in user. If you have AUTH_MODEL = yourapp.CustomUser in your settings.py , then request.user will be an instance of your custom user model.

Secondly, your filter is incorrect:

patient_list = newPatients.objects.filter(current_user.id)

You need to say which field you are filtering on, for example:

patient_list = newPatients.objects.filter(user=current_user)
