Django LoginView won't log in user
I have an app that is just meant to authenticate a user with Django's generic authentication views. The problem is that I can't log in a user even with the correct username and password. I keep getting an incorrect username or password error. The email and password are always simple such as, "email@email.com" and "123" as password so there's no way I'm messing up the spelling. I'm using Django's built in LoginView, a custom User model, and a custom AuthenticationForm. I've done this project before pretty much the same way with no issues but I can't find the difference between this project and my older project. This is my code. Thank you for your time.

How to properly implement Django form session wizard

Django-Allauth equivalent for Django Ninja?
I am developing a REST API for web application in Django Ninja and one of our project's assumptions is possibility of using Google SSO for authentication. Is there any equivalent of Django-Allauth for Django-Ninja? I haven't found anything similar and to be honest I have no idea on how to process that in Django Ninja. Thanks in advance. Kind regards -
Uploading image from aiogram bot in BytesIO format to Django ImageField using aiohttp post method
I'm receiving an image from aiogram bot and I'm saving it in BytesIO format to be able to send to my REST API with post method of aiohttp ClientSession. However, when I try to do that with the following code: import io import aiohttp from aiohttp import FormData # inside aiogram message handler image_in_bytes_io = io.BytesIO() await message.photo[-1].download(destination_file=image_in_bytes_io) formdata = FormData() formdata.add_field(name="image", value=image_in_bytes_io.read()) async with aiohttp.ClientSession() as session: async with session.post(url, data=formdata) as response: print(response.status) print(await response.read()) I'm getting status: 400 and error message: 'File extension \xe2\x80\x9c\xe2\x80\x9d is not allowed.' from my REST API. Can you show where I'm making a mistake? If this solution is wrong, can you show the correct way of uploading an image from aiogram bot to ImageField that is in REST API endpoint? Thanks :) -

In Django, how to temporatily store consecutive user inputs in the backend within 60s?
I am having trouble storing user inputs temporarily in Django backend (like 60 seconds for a game. Once the game is over, it should delete all user input records). To make it clear: I want to develop a website game using python and Django as backend languages, where it takes user input (one word as one input) and counts how many words a user can give in 60 seconds. The website should remain the same after each submission, but the game records each user input in the backend and counts on it while the game is still running. I think that I should use a session in Django but I'm still not sure about how should I approach this problem. As the picture shows, the input box can only take 1 word for each submission, and continue taking user inputs until the timer ends. So, how should I save these temporary user inputs using Django? -
Why does a non required field in a serializer serialize the field?
Say I have a serialiser like class DumbSerializer(serializers.Serializer): field_one = serializers.CharField(required=False, allow_null=True) And I do something like asdf = DumbSerializer(data={}) asdf.is_valid() >>> True asdf.data >>> {'field_one': None} asdf.validated_data >>> OrderedDict() Why is the serialization of {} represented as {'field_one': None} and not {}, given that field_one is not a required field? The python internal representation is an empty dict as I would expect -

I am new to Django | DRF and trying to create a DRF coupon system for course purchases , how can i limit the coupon validity on the basis of number of user used it or some specific time span for ex. only first 50 users can use the code or it will be valid only for next week.
