Django - PWA // How do I need to setup user data management?
I'm working on a pwa with django and I almost done all the front/backend and I'm now facing which might be the last part to put in place (I believe and hope so !) : User Data Management I already had a look at Django's documentation regarding user/group management and I think it is quite logical and understandable however I'm really stuck on how should I implement all of this according to my project ? And especially how should I manage user's data ? Today, the development part is already setup with models/data saving/editing. But there's no user dimension for now, everything created and stored in the database is "general" (I'm using SQLite3 mainly because it was easier to deal with for development and testing but I'm clearly not fixed to it and I can easily readapt parts of the code based on the chosen database and how it work, even more if other database are better adapted to what I am looking for). To give you a bit of context the application should allow anyone to create an account to access the app. When he user is logged on, he/she will be able to arrive on an interface with … -
Django loses static files

Django: Accounts activated automatically when sending verification emails
I have a problem in activating accounts on Django. When I send a clickable verification link by email, the account is getting activated automatically without needing the users to click on the link (I saw that the account was indeed activated without needing to click on it). On the other hand, when I send a non clickable link (so by removing the http:// in the beginning), the client can copy the link and paste and verify his account normally. I need to send a clickable link that require a user to manually click on it so his account gets activated.

Django - too many values to unpack (expected 2)
I'm trying to create a custom backend where an user uses a private key and a secret key to view an API endpoint that i made uing Django Rest Framework. I already know this isn't the best in terms of security, but since the endpoint is only for viewing data (it only has the GET method) it's not a big deal here.

Django not commiting to Database if response is rendered differently
I have the following code: # ... # obj creation logic # ... txt = "*BULK LIST*\n\n" for item in obj_list: txt += f"*Label*: {item.label}\n*Item Code*: {item.id}\n*Date Created*: {item.created_date}\n\n" txt += "========================\n\n" # Line with issue return http.HttpResponse( txt, content_type="text/plain" ) The objects in obj_list are only saved to database if the response is returned as shown above. Now, i've been reviewing my code on this project and this part was just too dirty, so I created a template PROJECT_ROOT/templates/bulk_view.html so that presentation will be handled separately in there. Here is the tiny change I made: # same object creation logic as above, removed 'txt' and the forloop concatenating the strings for presantation. # change made on the returned response return http.HttpResponse( render(self.request, "bulk_view.html", {"items": obj_list}) ) The items render correctly, with their ids implying they have been saved to the database. But that's not what's happening. They are not in the database, and also, the id increments on each save(). I'm using Django 3.1 and Postgres 12.4 -

Should I split my Django and DRF project into separate projects?
I am currently at the planning stage of an app that will consist of standard Django part for supervisors that can perform all CRUD operations on employee users mostly add, delete and view statistics - viewed in browser (no frontend framework just using Djangos server side rendering), two step email authentication on each login, session based auth DRF part for employees - API connected to mobile app, authentication based on device ID. (no username, or password) DRF part for clients to contact the supervisors if employees do something wrong - Token or JWT based authentication using passcode delivered by mail. I am not used to splitting Django projects into multiple sub-projects (or using same database for different projects) but it feels like every part of the project should be a standalone app due to different authentication type and the fact of simultaniousily using DRF with standard Django Can anyone who had similar problem or has some experience, advise what should I do considering different authentications and overall different user types in this project? What would be pros and cons of going into solo or multiple projects? Thanks in advance! -

Django: Count and Sum items in the same item_category within a queryset

How to allow a form to submit, but prevent blank fields from being saved using Django Admin?
I am using Django Admin, and have a model like this: class Item(models.Model): id = models.CharField(max_length=14, primary_key=True) otherId = models.CharField(max_length=2084, blank=True) I want id to be required and unique, and I want otherId to be optional on the Admin form, but if otherId is provided, it has to be unique. The problem I am running into is, whenever I create an instance of Item using the Admin form and I do not provide an otherId, Django tries to save the otherId field as a blank value, but this means the second time I try to save an instance with a blank otherId value it violates the column's unique constraint and fails. I need Django to check if the otherId field is falsey before saving, and if it is falsey, do not save that empty value along with the model. Is this possible? -
Django update model fields after a certain time
I have a Assignment model, which has the following attributes for now: title (char Field), deadline(date and time field), closed (boolean field). The closed field denotes if the assignment is past deadline or not. The closed field is false by default. So now, what I want is that, when an object of the model is created the closed field should be updated automatically on the basis of the deadline. Say the deadline is after 2 hours. Then the closed field should become true after 2 hours. What is the best way to do this? Does Django provide any field of this type; which would update itself after a certain time?
