Updating value on django model object does not update value on related foreign key model
I have 2 models, House and Room where Room has a foreign key to House: class House(models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) name = models.CharField(max_length=50) class Room(models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) name = models.CharField(max_length=50) color = models.CharField(max_length=50) house = models.ForeignKey(House, on_delete=models.CASCADE, related_name='rooms') When I run the following test, for some reason the colors are not matching, even though the ids do. Can someone help figure out why? def test_color_change(self): h = House(name='new house') h.save() r = h.rooms.create( name='living room', color='blue' ) r2 = h.rooms.get(name='living room') r2.color = 'green' r2.save() self.assertEqual(r.id, r2.id) self.assertEqual(r2.color, r.color) I've been looking at the django documentation for RelatedManager, but haven't been able to figure it out. I would have expected r and r2 to be pointing to the same object, but apparently they are not. -
Tracking Django sessions with custom cookies
I am looking for a way to track the time users spend on the site. I have found the package django-tracking2, which tracks visitors by the Django session. However, my session expiry is set to 2 weeks, which makes it useless to track daily activity. My thoughts are that I can create a different cookie that expires every day, so that I can use this cookie for tracking. However, I do not quite understand how exactly I would assign a random cookie every day for users, as the Django docs does not quite have examples on this. The desired logic is: When a user opens the app, check if cookie custom_cookie is set If not, create it with a random value (probably uuid4?) The cookie should expire the same day at midnight I have come across this way of creating cookies in the middleware, however I think it will yield different random values in the request and response objects: class MyCookieProcessingMiddleware(object): # your desired cookie will be available in every django view def process_request(self, request): # will only add cookie if request does not have it already if not request.COOKIES.get('custom_cookie'): request.COOKIES['custom_cookie'] = uuid.uuid4() # your desired cookie will be available … -

How to create model object that via user foreignkey, FOREIGN KEY constraint failed?
In my view I am creating the object model, and in this model that I am creating is one field, name=models.ForeignKey(User, on_delete=models.CASCADE). And I am using ForeignKey because in this object can be made multiple time by a single user. And I get an error django.db.utils.IntegrityError: FOREIGN KEY constraint failed Here is the model: from django.contrib.auth.models import User ... class Customer_status(models.Model): name = models.ForeignKey(User, null=True, on_delete=models.CASCADE) creation_date = models.CharField(max_length=28) status=models.CharField(max_length = 8) def __str__(self): return str(self.name) + '_' +str(self.id) And in this view I am creating this model: def status_create(request): if request.user.is_authenticated: print('This print work but after it, is an ForeignKey error') Customer_status.objects.create ( name=request.user, creation_date=datetime.datetime.now(), status='Pending' ) The thing is that I had OneToOne and I couldn't make more than 1 model from 1 user, after I changed it to ManyToMany I have the this error django.db.utils.IntegrityError: FOREIGN KEY constraint failed. When it was models.OneToOne, request.user worked, but when I put ForeignKey, it doesn't work -

How can I set Django views depending on api source?
I need to show my django views after login when api boils. But I can't provide this because it validates from a database in django in standard django functions. When the API I set up with Fastapi boils, I can login by generating access_token, but then I cannot authorize my viewsets or condition a condition such as access_token_required.

django DRF Performance problems with logic with multiple conditions
The shopping cart model stores cart items for both guest users and registered users. I provide the guest user a unique key using uuid and save it to the cookie. The situation that I want is to link the cart items that is included in the guest user's status to the login user's cart. So I wrote logic considering 3 situations. When you are a guest user, press the shopping cart button to create a cart model. If you fill up the shopping cart before logging in, remove the unique key of the shopping cart model and update it with your user information. If you press the shopping cart button after logging in immediately, create a cart immediately. Does configuring logic under these three conditions adversely affect performance? Is it common to use multiple conditions like this? Is it overloading the server? Help me improve my logic. thanks @api_view(['POST']) def addToCart(request): user = request.user data = request.data guest_id = request.COOKIE.get('guest_user') #if anonymous user puts item in the cart if not request.user.is_authenticated: cart = Cart.objects.create( guest_id = guest_id ) CartItems.objects.create( cart = cart, product = data['product_id'], product_option = data['product_option'], qty = data['qty'] ) serializer = CartSerializer(cart, many=False) return Response(serializer.data) #if guest_user … -
