Model object has no attribute 'get'

using Django 1.11 I'm stuck with uuid referencing in my views. I read through all similar looking questions here, but they either focus on forms or anything else.

Minimal example

It's an app called MegaTest. It's bound to /testuuid/

I have a working index view that generate links to /testuuid/<uuid>

If I click on a link on my index page, I get:

AttributeError at /testuuid/5a147a14-a9a9-4045-8e79-0ce2e8258a68/
'MegaTest' object has no attribute 'get'

models.py

class MegaTest(models.Model):
    uuid = models.UUIDField(db_index=True, default=uuid.uuid4,
               editable=False, unique=True)
    name = models.CharField(max_length=128, blank=True, null=True)

views.py

class IndexView(generic.ListView):
    template_name = 'testuuid/index.html'
    context_object_name = 'test_list'

    def get_queryset(self):
        """Return the last five published questions."""
        return MegaTest.objects.all()


class MegaTestDetailView(generic.DetailView):
    model = MegaTest

    def get(self, request, uuid):
        try:
            megatest = MegaTest.objects.get(uuid=uuid)
            return megatest

        except MegaTest.DoesNotExist:
            raise Http404

urls.py

app_name = 'testuuid'
urlpatterns = [
    # ex: /polls/
    url(r'^$', views.IndexView.as_view(), name='index'),
    url(r'^(?P<uuid>[\w-]+)/$', views.MegaTestDetailView.as_view(), name='detail'),
]

testuuid/index.html

{% if test_list %}
    <ul>
    {% for test in test_list %}
        <li>
            <a href="{% url 'testuuid:detail' test.uuid %}">{{ test.name }}</a></li>
    {% endfor %}
    </ul>
{% else %}
    <p>No tests available.</p>
{% endif %}

I assume a damn simple mistake, but I really have no clue at this point.

You should override get_object() method instead of get().

class MegaTestDetailView(generic.DetailView):
    model = MegaTest

    def get_object(self):
        try:
            megatest = MegaTest.objects.get(uuid=self.kwargs['uuid'])
            return megatest

        except MegaTest.DoesNotExist:
            raise Http404

You can also work with get_queryset() or even just specify pk field in url and don't write any method in the view class. Django will automatically query on your specified field in pk_url_kwarg
