queryset object not callable Django

Question

I wanted to make a search bar which search the database for queries in django and have come up with this so far:

view:

class IndexView(LoginRequiredMixin, generic.ListView):

    template_name = 'patients/index.html'
    context_object_name = 'all_patients'

    def get_queryset(self):
        queryset = patient.objects.all()
        query = self.request.GET.get('q')

        if query:
            queryset = queryset.filter(
                Q(First_Name__icontains=query) |
                Q(Surname__icontains=query) |
                Q(DOB__icontains=query)
            ).distinct()
            return queryset

        else:
            return patient.objects.all()

and my button on my template:

<form class="navbar-form navbar-left" role="search" method="get" action="{% url 'patients:index' %}">
  <div class="form-group">
    <input type="text" class="form-control" name="q" value="{{ request.GET.q }}">
  </div>
  <button type="submit" class="btn btn-default">Search</button>
</form>

and the model:

class patient(models.Model):

    TITLE_CHOICES = (
        ('Mr', 'Mr'),
        ('Mrs', 'Mrs'),
        ('Ms', 'Ms'),
        ('Miss', 'Miss'),
    )

    Title = models.CharField(max_length=100, blank=True, choices=TITLE_CHOICES)
    First_Name = models.CharField(max_length=250, default='')
    Surname = models.CharField(max_length=250, default='')
    DOB = models.DateField()
    ...

    def get_absolute_url(self):
        return reverse('patients:patientInfo', kwargs={"pk":self.pk})

    def __str__(self):
        return self.First_Name + " " + self.Surname

I am getting the error:

TypeError: 'QuerySet' object is not callable

I have no clue what I am doing wrong and am very new to Django.

Answer 1

I encountered this problem when I added a property, then it's a method and can't be callable

@property
def get_queryset(self):

so I fixed it by removing the property
