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 -
Django cart management
I work on a cart management application, I use the django-shopping-cart 0.1 package, At the level of my project I use a dictionnary the products then add them to the basket, Also noted the products are added by setting the product code. def cart_add(request, code): dico={"produits":[{'code':'fg21','name':'coca cola','prix':1500}, {'code':'br21','name':'pomme','prix':1800}]} all_produits=dico['produits'] all_product = next((item for item in all_produits if item["code"] == code), None) if selected_product != None: cart = Cart(request) product = selected_product cart.add(product=product) return render(request, 'cart/detail.html',context) Here the error comes from the cart.py module of django-shopping-cart 0.1 At line level (id = product.id) I am told the dic object has no code attribute even if I do (id=product.code) cart.py class Cart(object): def __init__(self, request): self.request = request self.session = request.session cart = self.session.get(settings.CART_SESSION_ID) if not cart: # save an empty cart in the session cart = self.session[settings.CART_SESSION_ID] = {} self.cart = cart def add(self, product, quantity=1, action=None): """ Add a product to the cart or update its quantity.

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?

I am trying to upload image to the server. I received Imagename (string) and Imagefile (multipart) from android, Imagename is successfully saved with below algorithm but Imagefile wasn't.

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? -

Django query fetch foreignkey association without N+1 queries in database

How to make more than one fields primary key and remove auto generated id in django models
Suppose in a relational database schema we have a student, a subject and a teacher which connect to each other with a relation teaches. Also, the relation has an attribute time that stores the time of the lesson. This is the most complete yet simplified example I can think to describe my case. Now, the most pythonic and django-wise way I can think of trying to reach a correct solution is, after creating a model class for student, subject and teacher, to create a new class Teaches, which has the foreign keys for the three other classes; also it has the property date field for time. This class would look something like this: class Teaches(models.Model): teachers = models.ForeignKey(Teacher, on_delete_models.CASCADE) subjects = models.ForeignKey(Subject, on_delete_models.CASCADE) students = models.ForeignKey(Student, on_delete_models.CASCADE) time = models.DateField class Meta: constraints = [ fields=['teachers', 'subjects', 'students'] name='teacher_subject_student_triplet' ] I added the Meta class because this is what this answer recommends as the correct approach. The problem is that that in the migrations file I can still see the id field. The only way I've seen there is to remove it is to set another field as Primary Key, but in my case I cannot do that, having more … -
