Django Rest Framework trying to update or create a related model but need the related object
I have a profile model and a location can belong to a profile. But a person might not add the location when they create the profile so I would like to update or create the profile if it does not exist, when the user adds it later. I tried doing it through the profile serializer but there is no request data so I cannot create or update a location model object. So I presume I have to do it through the view and here it is: class UpdateProfileView(generics.UpdateAPIView): permission_classes = [permissions.IsAuthenticated] serializer_class = ProfileSerializer name = "update-profile" def get_queryset(self): id = self.kwargs["pk"] return Profile.objects.all().filter(id=id) def update(self, request, *args, **kwargs): street = request.data.get("street") user = User.objects.get(id=request.data.get("user")) city = City.objects.get(id=request.data.get("city")) additional = request.data.get("additional") zip_code = request.data.get("zip") name = user.profile.first_name + '\'s location' user_location = Location.objects.update_or_create(name=name, street=street, additional=additional, city=city, zip=zip_code, profile=?) My question is three fold: Is this the best way to update or create a model object for location? If I create the location this way will the profile still be updated as well or am I missing data I should add? How do I get the profile instance that is for a field (profile=?) I have to fill for location. I … -
Django - allauth: How to keep only the allauth login url
How can I remove the allauth signup URL while keeping the login URL in Django? I am using the allauth package for authentication and I would like to only keep the login URL while removing the rest URLs as i have project that needs only the login.

I was expecting to only remove the signup URL while keeping the login URL accessible through allauth package in Django -
django view filter ManyToMany field to guard view
I have a tag model, with ManyToMany field "parents" to tag model, to itself. There is also "allowed_users" field. I need to guard a view in such a way, that the user won't see any tags in parents field, to which he is not allowed. I try to modify queryset, removing the corresponding tags from parents. But when I change the instance, tag_instance.parents.set(my_new_list) it gets saved automatically so I'm altering the database and changing the real value of the instance. So the general question is "how to guard my view in such a way, that object's ManyToMany field is filtered by custom logic". Another question is "how to set manytomany field without altering database", as this would be a solution to the former one. yes I use DRF -

Sending email feature not working when run using Docker. Showing Error : 530, b'5.7.0 Authentication Required. But runs perfectly without docker
I am making a Django App using GraphQl APIs in which I am trying to make an email sending feature for changing and sending user password if they forget while login. This feature is perfectly working when I am running it from my laptop's localhost:8000, but when I pushed it to dockerhub using github actions, and pulled it and tried to run, it didn't work.

SESSION_COOKIE_AGE vs set_expiry() in Django
I have noticed different behavior between SESSION_COOKIE_AGE and set_expiry method. Usually, I am using set_expiry on login as it changes according to the user whether he/she selects REMEMBER BE or not. I understand that if I set SESSION_SAVE_EVERY_REQUEST to True, this means that the expiration date will be updated every time on user activity. However, I noticed that the expiration date of the session is updated on user activity without setting SESSION_SAVE_EVERY_REQUEST (default: False) and without modifying the session. On the other side, it is not working that way if I set SESSION_COOKIE_AGE only without custom setting of set_expiry. From the documentation, it is mentioned that if we set value using set_expiry: the session will expire after that many seconds of inactivity Is that means INACTIVITY in accessing the application or inactivity in modifying the session? And set_expiry equals SESSION_COOKIE_AGE plus SESSION_SAVE_EVERY_REQUEST=True? -

How to embed an XLSX local file into HTML page with Python and Django
For a Python web project (with Django) I developed a tool that generates an XLSX file. For questions of ergonomics and ease for users I would like to integrate this excel on my HTML page. So I first thought of converting the XLSX to an HTML array, with the xlsx2html python library. It works but since I can’t determine the desired size for my cells or trim the content during conversion, I end up with huge cells and tiny text.. I found an interesting way with the html tag associated with OneDrive to embed an excel window into a web page, but my file being in my code and not on Excel Online I cannot import it like that. Yet the display is perfect and I don’t need the user to interact with this table. I have searched a lot for other methods but apart from developing a function to browse my file and generate the script of the html table line by line, I have the feeling that I cannot simply use a method to convert or display it on my web page. I am not accustomed to this need and wonder if there would not be a cleaner … -

How to use foreign key as a distinct value and sort the queryset with a timestamp field first in Django?
I am using Postgres in my django project and I want to get all the tickets based on a customer full_name search with distict customer_id and sort the ticket queryset based on card_timestamp field in Ticket model. I have two models like the following: class Ticket(BaseTimeClass, BaseDeletedClass): customer=models.ForeignKey(Customer,on_delete=models.CASCADE, related_name="generated_tickets") is_replied = models.BooleanField(default=False) is_resolved = models.BooleanField(default=False) card_timestamp = models.DateTimeField(blank=True, null=True) class Customer(BaseDeletedClass): created_at = models.DateTimeField(auto_now_add=True, blank=True, null=True, db_index=True) modified_at = models.DateTimeField(auto_now=True, blank=True, null=True) first_name = models.CharField(max_length=64, default="") last_name = models.CharField(max_length=64, default="") full_name = models.CharField(max_length=256, default="") I have tried with this: Ticket.objects.filter(Q(customer__full_name__icontains="shuvo")) .select_related("customer") .order_by("customer_id", "-card_timestamp") .distinct("customer_id") ) the problem with this query is, it is returning the queryset sorted by the customer_id 1st then using the card_timestamp. for better scenario, e.g. there can be multiple customer named with "shuvo": customer_id can be 1870, 1120, 3210, and their card_timestamp value is "13 january 2023", "28 december 2022" and "14 december 2022". expected scenario, the queryset should return customer_id 1870, 1120 and 3210 sequentially but it is returning customer_id 3210,1870, 1120. how to solve this problem using django-orm? thanks in advance! -
