urllib [Errno 11001] getaddrinfo failed with windows proxy
I'm running Django 3.2 with django-tenants on a Windows local dev environment. In my windows hosts file I have: 127.0.0.1 *.localhost ...so that I am able to use subdomains with django-tenants. E.g. http://mysub.localhost:8000. When running ./manage.py runserver the dev server runs perfectly. However, when trying to execute urlopen in my code I get an error: >>> html = urlopen('http://mysub.localhost:8000') Traceback (most recent call last): [...] urllib.error.URLError: <urlopen error [Errno 11001] getaddrinfo failed> As far as I can tell the error is due to the proxy settings on my windows machine (this does not fail in production), but I am unsure how to resolve it? -

Saving objects to postgresql with DJango in UTC instead of local timezone?
I have a column in my table called "signed_up_date", which I am using the auto_now_add=True parameter with the DateTimeField() function. I want this function to save timestamps to the PostgreSQL DB in UTC instead of my local time (EST) which it is currently doing. Barebones version of the model for quick ref below: class TutorTest(models.Model): signed_up_on = models.DateTimeField(auto_now_add=True) Settings.py LANGUAGE_CODE = 'en-us' TIME_ZONE = 'UTC' USE_I18N = True USE_TZ = True I thought based on the docs, if I have Time_Zone set to UTC and UTC_TZ set to True, then the default behavior of Django would be to save as UTC. I know when I check postgresql timezone I get: SHOW TIMEZONE; TimeZone ------------ US/Eastern (1 row) I just tried a new model with timezone.now() and it looks like in the db shell I get: datetime.datetime(2022, 9, 21, 14, 36, 16, 670726, tzinfo=datetime.timezone.utc) But the db saved it as: 2022-09-21 10:35:26.633116-04 I guess it's the DB in this situation? Confused lol -

How to re-save a ModelForm?
I instantiate a ModelForm based on some input data, and then I generate/fetch some new data based on that input data, and want to refresh my ModelForm with the new data and then save it. I would rather like to use ModelForms as much as possible and avoid having to use the associated Model object directly when it comes to saving/validation and other stuff (e.g. white-space trimming). One solution would be to instantiate another new ModelForm based on the new (and the previous) data and feeding it the generated Model object via instance argument, then save() again, but, is there another better/neater/more optimized way, without having to instantiate two ModelForms?

How to update/change attribute in Django Class Based View Test
I created a mixin that requires an attribute to be added to a Class Based View (cbv) and it works as expected - but I'm having a tough time 'testing' that mixin specifically. Here is my test: class TestView(GroupRequiredMixin, View): group_required = ("test_group",) raise_exception = True def get(self, request): return HttpResponse("OK") class GroupRequiredMixinTest(TestCase): def setUp(self): group = GroupFactory(name="test_group") self.user = UserFactory(groups=(group,)) def test_view_without_group_required_improperly_configured(self): rfactory = RequestFactory() request = rfactory.get("/fake-path") request.user = self.user view = TestView() view.group_required = None with self.assertRaises(ImproperlyConfigured): view.as_view()(request) This test errors with this message: AttributeError: This method is available only on the class, not on instances. What is the 'appropriate' way to test this? Should I be setting up a unique class for each situation I want to test? Or is there a way I can dynamically change that attribute on an instance like in my test that fails? -
