Drf token authentication password reset
I'm wondering whether Django rest framework token authentication has password reset property. I have a Django app where I'm using token authentication to register and login users. But I was told that in order for me to implement password reset in the Django app I have to switch to packages like JWT or Knox. But I would like to use drf token authentication without switching to jwt or Similar package. How should I go about this, is it possible? -

Connecting IoT Device with HTTPS Endpoint (Django Web App) via AWS IoT Core
Web technology and aws are new to me. My goal is to send data from a device to Django web app via AWS IoT Core. In AWS IoT Core, there is an option to added HTTPS endpoint for Routing data directly from IoT Core to web services. I have been able to receive data from device to AWS IoT Core and add HTTPS endpoint (Django web app hosted on Heroku) by adding key received on Heroku log from AWS. In AWS, it shows endpoint enabled after adding the key. Now, whenever device sends payload, I am expecting the payload to be routed to web app. I am watching log to verify this, but I cannot see data. I am expecting that once payload appears in log, I should be able to read data using HTTP GET and display on html frontend. Is my expectation correct or am I missing something? -
Inconsistency Errors in kombu using celery and redis with the key '_kombu.binding.reply.celery.pidbox'
I have two Django sites (archive and test-archive) on one machine. Each has its own virtual environment and different celery queues and daemons, using Python 3.6.9 on Ubuntu 18.04, Django 3.0.2, Redis v 4.0.9, celery v 4.3, and Kombu v4.6.3. This server has 16 GB of RAM, and under load there is at least 10GB free and swap is minimal. I keep getting this error in my logs: kombu.exceptions.InconsistencyError: Cannot route message for exchange 'reply.celery.pidbox': Table empty or key no longer exists. Probably the key ('_kombu.binding.reply.celery.pidbox') has been removed from the Redis database. I tried downgrading Kombu to 4.5 for both sites per some stackoverflow posts and setting maxmemory=2GB and maxmemory-policy=allkeys-lru in redis.conf per celery docs (https://docs.celeryproject.org/en/stable/getting-started/backends-and-brokers/redis.html#broker-redis); originally the settings were the defaults of unlimited memory and noeviction and these errors were present for both versions of kombu I still get those errors when one site is under load (i.e. doing something like uploading a set of images and processing them) and the other site is idle. What is a little strange is that on some test runs using test-archive, test-archive will not have any errors, while archive will show those errors, even though the archive site is not doing … -

Why I cannot see a error message from ValidationError Django?
I have done what is written on Django Documentation and I have tried several Youtube tutorials, including Stackoverflow's advice.

Creating a dropdown menu in python django and adjust website values according to the selection
I have a django framework with a template that has different versions in terms of content. As a User I would like to be able to select the version I want in a dropdown menu and adjust the contents of the website accordingly. Is there a way to create a dropdown menu like that if the content only changes in terms of certain values displayed on the website (e.g. if "3" is selected in the menu, change all the according placeholders to "3") without requiring the use of backend logic or some reactive frontend framework? -
Django: 'str' object has no attribute 'get'

Django Views and Model: Create ManyToMany User relationship with all other relationships - triangular number series problem
I have 4 models: class User(models.Model): ... class Invite(models.Model): ... user = models.ForeignKey( User, related_name="invites", on_delete=CASCADE) class House(models.Model): ... members = models.ManyToManyField(User, related_name="houses") class Balance(models.Model): balance_owed = models.DecimalField( max_digits=10, decimal_places=2, default=0) two_users = models.ManyToManyField(User, related_name="between_balance") As a User joins a house, I want that user to create a balance with ALL other users in the house. Number of Balance instances per User will start to form a triangular number sequence (for ref see https://www.101computing.net/triangular-numbers/ ); The pattern for number of Balance instances per User would look like: 1, 3, 6, 10, 15 etc. And on a grid, the relationships would look like: User1 User2 User3 User4 User1: x bal bal bal User2: bal x bal bal User3: bal bal x bal User4: bal bal bal x This is where I'm lost! In my views.py I tried: my_invite.house.members.add(this_user) # this_user is the one joining the house all_users = this_house.members.all() # store all members of house, including new user for user in all_users: balance_obj = Balance.objects.create() balance_obj.two_users.add(user) balance_obj.two_users.add(this_user) Unfortunately this does not satisfy a forming of relationships between every single user. I'm guessing this requires some kind of algorithm perhaps? Thank you in advance for your input -

Problems with different types of test databases
I am working on a large Django project with lots of tests. To improve the performance I want to make the test database persistent - by default, it's in memory. One exemplar test class runs perfectly fine in in-memory Sqlite3. When I switch to MariaDB, I get stacked exception for all but the first test case: django.db.transaction.TransactionManagementError: An error occurred in the current transaction. You can't execute queries until the end of the 'atomic' block. and MySQLdb._exceptions.OperationalError: (2006, '') So I thought it may be a problem with MariaDB, I switch to file-based SQLite3. But there, again - on the same tests! - a stacked exception: sqlite3.ProgrammingError: Cannot operate on a closed database. and django.db.utils.ProgrammingError: Cannot operate on a closed database. The interesting thing is that lots of tests work and the code looks good. I tried to get the broken query which causes the transaction in MariaDB to fail but after searching around for an hour, I ended up with zero results. Looking for closed database connections to SQLite always points to some custom shenanigans what I am not doing. I am running Django (v2.2.23) on Windows 10 Pro with PyCharm (latest). -

Sorting queryset by repeating values in django
There is a school with a total of 12 classes. 9-A, 9-B, 9-C 10-A, 10-B,10-C 11-A,11-B,11-C We have students in each class and I want to order a queryset that contains these students. We can access the degree and letter of the class separately. I want to order them like that : 9-A 10-A 11-A 9-B 10-B 11-B 9-C 10-C 11-C (A B C is not sorted, it should be random. I want to sort 9 10 11.) It will repeat itself every three times like 9,10,11,9,10,11. I couldn't figure how to write a query to sort them with this algorithm. students= Student.objects.distinct().filter(exams__schedule_id=1).order_by('') Here is the student queryset. How should I fill order_by part ? -
