Custom Django Allauth Forms Not Being Stored in Database
I'm trying to extend Django Allauth's signup form to contain additional fields. These fields show up fine in my form but they do not store the submitted data in the database. I have tried following solutions here and here to no avail. forms.py: from allauth.account.forms import SignupForm from django import forms from .models import User from django.forms.widgets import NumberInput import datetime class CustomSignupForm(SignupForm): age = forms.CharField(max_length=30, label='Age') date_of_birth = forms.DateField(widget = NumberInput(attrs={'type':'date'})) def save(self, request): user = super(CustomSignupForm, self).save(request) user.age = self.cleaned_data['age'] user.date_joined = datetime.datetime.now() user.date_of_birth = self.cleaned_data['date_of_birth'] user.save() return user models.py: from django.db import models # Create your models here. class User(models.Model): age = models.PositiveSmallIntegerField() date_of_birth = models.DateField() date_joined = models.DateField() def __str__(self): return self.name settings.py: AUTHENTICATION_BACKENDS = [ 'django.contrib.auth.backends.ModelBackend', 'allauth.account.auth_backends.AuthenticationBackend', ] SITE_ID = 1 ACCOUNT_AUTHENTICATION_METHOD = 'email' ACCOUNT_EMAIL_REQUIRED=True ACCOUNT_EMAIL_VERIFICATION='mandatory' ACCOUNT_AUTHENTICATED_LOGIN_REDIRECTS = False ACCOUNT_EMAIL_CONFIRMATION_EXPIRE_DAYS = 3 EMAIL_BACKEND = 'django.core.mail.backends.console.EmailBackend' LOGIN_REDIRECT_URL = '/' ACCOUNT_FORMS = { 'signup': 'core.forms.CustomSignupForm', } Somewhere mentioned having: AUTH_USER_MODELS = 'myproject.User' however this throws up an error about User having no required fields.

Django - assign a single record from a queryset to a user and update it. Only releasing the record to another user if the transaction fails
I'm a Django beginner and I'm trying to create a warehouse management system in Django. The system keeps track of what products enters the warehouse and therefore knows what is in the warehouse and at which location. There are several users (order pickers) who are logged in simultaneously and who have to get the products from the warehouse. My model looks like this: class Product(models.Model): location = models.IntegerField(validators=[MinValueValidator(1),MaxValueValidator(5000)]) already_picked = models.BooleanField(default=False, blank=True) available_for_picking = models.DateField(blank=True, null=True) def __str__(self): return str(self.id) The products that have to be picked from the warehouse on a certain day must meet a number of conditions. For instance: available_for_picking = today or date in the past AND aldready_picked = False What I want to do: Every user goes to the url: www.mydomain.com/get_order_location_to_pick and gets a location of a product that he has to pick up from the warehouse. However, there are several products that meet the selection criteria and there are several users who use the software at the same time. So I want to avoid assigning the same product (and location) to more than 1 user. When the user has taken the product, boolean "already_picked" should be changed from False to True. If the user … -
Parse multipart/form-data in Python
I'm trying to parse an incoming multipart/form-data request sent to a Django python server. I WILL NOT use Django REST server - it shouldn't be necessary to import an entire library on top of another library to parse a multipart form.

Filter data of a JavaScript chart by date range - Django Project

prevent multiple form submissions
I have been looking for a way to prevent users from clicking the submit button on a form multiple times resulting in the post being submitted multiple times. Most of the post I found on stack were at least 5 years old and they all offered different ways to solve the issue, there didn't appear to be a best practice method on how to remedy this issue. I took a quick look in the docs to see if they have added anything but I didn't see anything. In 2021 what is the best practice to prevent multiple form submissions. -
Expected view Equation1View to be called with a URL keyword argument named "pk"
I'm trying to get data directly from request body in json. Making calculations in API will be main part of my Django REST Api. In the future I'm going to add database from which I'll be getting some data that will be used in calculations. I'm having a problem with error AssertionError: Expected view Equation1View to be called with a URL keyword argument named "pk".

Using the api below I should be able to send {"name":"xxx", value:1.23} in request body and get {"emission":1.23} in json response. Ofcourse it will be more complicated in future as getting more data from request body and connecting it with data from db but now I have to make it simple. api urls.py: from .views import Equation1View from django.urls import path urlpatterns = [ path('equation/1', Equation1View.as_view()) #path('equation/2'), #path('equation/3'), ] views.py from aiohttp import request from rest_framework import generics from .serializers import EmissionSerializer, EquaSerializer # Create your views here. class Equation1View(generics.RetrieveAPIView): queryset = '' serializer_class = EquaSerializer(context={'request':request}) serializers.py from rest_framework import serializers class EquaSerializer(serializers.Serializer): emission = serializers.SerializerMethodField('perform_equation') def perform_equation(self): request = self.context.get("request") if … -
