Django two-phase user registration form with email verification
I am trying to implement a Django registration app that at first takes the initial details from an User, then sends an email with a link to verify their email and directly login, and then provides them with another form to complete their registration. After the email verification, the status of 'is_active' and 'email_confirmed' field should change, but it does not change and remains at it's default value, i.e. false. Also, the data from the second form seems to be not registered, as when printing out the 'location' value, it always remains blank, even when entered in the form. How do I get to update these fields? These are the files for the app, called 'core'. The completeRegistration view is for handling the second form. My models.py file from __future__ import unicode_literals from django.db import models from django.contrib.auth.models import User from django.db.models.signals import post_save from django.dispatch import receiver class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) bio = models.TextField(max_length=500, blank=True) email_confirmed = models.BooleanField(default=False) fee_paid = models.BooleanField(default=False) def __str__(self): return self.user.username class Extendedprofile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) location = models.CharField(max_length=30, blank=True) def __str__(self): return self.user.username forms.py file: from django import forms from django.contrib.auth.forms import UserCreationForm from django.contrib.auth.models import User from .models import Profile, … -
How to add more model Field in Django based on input from HTML

CORS header missing when project hosted in a Subpath
I have a Django(v2.2) project hosted on an url which looks like https://some.example.com/mypath/ which has an API endpoint at blog/create. I need to make a POST request from https://some.example.com/anotherpath/ofmine/ (using axios), but that gives me a 301 error with the following messages in Firefox 71.0: Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://some.example.com/mypath/blog/create/. (Reason: CORS header ‘Access-Control-Allow-Origin’ missing). Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://some.example.com/mypath/blog/create/. (Reason: CORS request did not succeed). However, I can easily make the same requests to a dev server hosted locally. Relevant settings: INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'rest_framework', 'rest_framework_docs', 'corsheaders', 'django_extensions', ... ] USE_X_FORWARDED_HOST = True FORCE_SCRIPT_NAME = '/mypath' What could be the reason and possible workarounds for the error? -
Django filtering a timedelta error: TypeError: expected string or bytes-like object
I have a model Run that contains start_time and end_time timestamps that signify the beginning of data measuring, and the end (we call that a "run"). class Run(models.Model): start_time = models.DateTimeField(db_index=True) end_time = models.DateTimeField() Recently, a customer has started to perform new types of operations, and one of those requires them to know the duration of a run (easy enough to figure out), but also filtering a table based on that duration. The filtering is the part I don't have. So trying to filter by duration (a field we don't have on the model), I came up with the following query: from django.db.models import F test_query = Run.objects.all().annotate(duration=F('end_time') - F('start_time')) By using annotate, along with F operations, I am able to add a new temporary field to my query, called "duration". This part works as expected. The problem comes down to trying to filter by that newly generated annotation, by using __gte and __lte filters: from datetime import timedelta from django.db.models import F test_query = Run.objects.all().annotate(duration=F('end_time') - F('start_time')).filter(duration__gte=timedelta(seconds=50)) For simplicity's sake, let's assume I only want to get Runs that are 50 seconds or longer, as an example. My work so far with timedelta has been straightforward enough. end_time - … -
Django choice form to determine the class and fields used
Ideally I would like the user to be presented with two forms, after filling in the 'type' form (Modern/Retro), to then be shown the field attributes specified within the classes. My forms.py looks like this at the moment to hopefully make it clearer what I'm after: from django import forms from .import models class AddGame(forms.ModelForm): class Meta: model = models.Game fields = ['name', 'type'] if type == 'Retro Game': model = models.RetroGame fields = ['name', 'type', 'platform', 'genre', 'slug', 'developer', 'rom', 'bios', 'emulator'] elif type == 'Modern Game': model = models.ModernGame fields = ['name', 'type', 'genre', 'publisher', 'slug', 'developer', 'online_play'] -
Automatically retrieve a value from session as integer?
My Django app uses a Cart class like below: class Cart: def __init__(self, request): self.session = request.session if self.session.get('cart'): self.cart = self.session['cart'] else: self.cart = {} def add_product(self, product, quantity=1): if self.cart.get(product.id): self.cart[product.id]['quantity'] += quantity else: self.cart[product.id] = { 'name': product.name, 'quantity': quantity, } self.save() def remove_product(self, product): del self.cart[product.id] self.save() def save(self): self.session['cart'] = self.cart As you can see, add_product method accepts product, which is an instance of Product model. As such, its id attribute is an integer. However, upon calling Cart's class save method, this integer gets converted into a string, which breaks the functionality of add_product (as it expects an integer). I know I could manually convert product.id to string in add_product to fix this (and also in remove_product etc.), but is there a cleaner way? Like automatically telling the session that whenever the cart is retrieved from session, the products' ids should be retrieved as integers? -

Unable to access API despite entering the token
I have an API that's only accessible by passing a JWT token. I am using Simple-JWT library in Django. Also, I have stored this token within my localStorage and I obtain it within my views module via Ajax. I created an API using the GET method and it should retrieve back certain data from the model. However, when accessing the API URL via the Requests module in Python, it still says that authentication credentials were not provided.

How to index just selected json key using Django functionality instead of all keys?

Currently the code above indexes both name and lang keys. Is it possible using Django to index just name key? I found how to workaround this using SQL directly, but I just want to know, if it is possible to do that just via Django. I use Django 2.2 and PostgreSQL 12. -

How to perform a single sign on between Django app and React JS app?
I have a django app and a react js app. The django app has some views, while the react dashboard is the link between the different views of the django app. My objective is: When user signs into the react app, the django app should also be logged in and logged out simultaneously.

Password not saving when creating user
I know there are hundreds of posts about that topic but, in all of them, there is something slightly different from my own program and I can't adapt it to my program because the Django way of handling password is such a mess that I understand nothing. A little help would be greatly appreciated, I thank you in advance. So, when a new user registers, everything works perfectly but, somehow, the password is not saved in the database. When I go to the admin interface, it tells me that the password format is invalid or the hashag function is not known.

Django create instance of class from a choice select field
I am currently building a simple game library web app. My models.py file has two child classes (RetroGame, ModernGame) that inherit from the class 'Game'. When users add a new game to their library, it will be either a ModernGame or RetroGame. I'm trying to figure out how to set up a choice selection form that will then display the extra attributes I have listed within the child classes. Here is the code I have so far: from django.db import models from django.contrib.auth.models import User class Game(models.Model): name = models.CharField(max_length=200) genre = models.CharField(blank=True, max_length=100) players = models.PositiveIntegerField(default=1) publisher = models.CharField(blank=True, max_length=200) developer = models.CharField(blank=True, max_length=200) slug = models.SlugField() date_added = models.DateTimeField(auto_now_add=True) author = models.ForeignKey(User, on_delete=models.CASCADE) game_type = ( ('Retro', 'Retro Game'), ('Modern', 'Modern Game') ) type = models.CharField(max_length=6, choices=game_type) game_platform = ( ('PC', 'PC'), ('PS4', 'PS4'), ('XB1', 'Xbox One'), ('NS', 'Nintendo Switch') ) platform = models.CharField(max_length=3, choices=game_platform) def __str__(self): return self.name class ModernGame(Game): online_play = models.BooleanField(default=False) class RetroGame(Game): rom = models.CharField(blank=True, max_length=200) bios = models.CharField(blank=True, max_length=200) emulator = models.CharField(blank=True, max_length=200) -
Django Admin Validation for Inline ModelAdmin
I am using Tabular Inline for my admin page in which for an instruction there could be multiple scrap_code and event_code. But one scrap_code or event_code cannot have multiple instructions. I have made scrap_code and event_code throughout the table so that they cannot be duplicated. My admin.py class InstructionAdmin(admin.ModelAdmin): inlines = [ ScrapEventInstructionMapInline, ] fields=('name',) form = InstructionMapForm I need to show the users an alert when they try to enter event_code or scrap_code which already exists. But the problem is even if we have data instruction, s_code and e_code are coming as None My forms.py file:- class InstructionMapForm(forms.ModelForm): def clean(self): instruction = self.cleaned_data.get('instruction') s_code = self.cleaned_data.get('scrap_code') e_code = self.cleaned_data.get('event_code') qs = ScrapEventInstructionMap.objects.all() if s_code: dup_scrap = list(ScrapEventInstructionMap.objects.filter(scrap_code=s_code).values('scrap_code')) if dup_scrap: raise forms.ValidationError ('The Scrap Code provided ({}) already exists, kindly edit it or provide another Scrap Code'.format(s_code)) elif e_code: dup_event = list(ScrapEventInstructionMap.objects.filter(event_code=e_code).values('event_code')) if dup_event: raise forms.ValidationError ('The Event Code provided ({}) already exists, kindly edit it or provide another Event Code'.format(e_code)) How to get the data avoiding None? And how to show the alert to users? -

Setting the selected value on a Django forms.select()
I am changing the code already written before me. There are a couple of selects that somehow remember the existing value when changing the record, I need to add another one. Repeated all the steps, but nothing works. I want to figure out what's wrong. model.py class Deal(models.Model): service = models.ForeignKey( Service, on_delete=models.CASCADE, related_name='deals_services' ) currency = models.ForeignKey( Currency, on_delete=models.CASCADE, related_name='deals_currencies' ) amounts_rule = models.TextField() comission_rule = models.TextField() weight_rule = JSONField(null=True, blank=True, default=dict()) active = models.BooleanField(default=True) provider_enabled = models.BooleanField(default=True) min_amount = models.IntegerField(default=0) max_amount = models.IntegerField(null=True, blank=True) payment_types = ArrayField(models.CharField(max_length=30), default=list()) adapter_account = models.ForeignKey( AdapterAccount, on_delete=models.CASCADE, related_name='deals_adapter_accounts' ) contractor_params = JSONField(null=True, blank=True, default=dict()) # Serializer @property def currency_iso_name(self): return str(self.currency) @property def service_name(self): return str(self.service) @property def adapter_account_name(self): return str(self.adapter_account) @signal_sending(pre_save_with_user, post_save_with_user) def save(self, *args, **kwargs): super(Deal, self).save(*args, **kwargs) def __str__(self): return 'Deal #{}'.format(self.pk) class Meta: db_table = '"processing"."deal"' permissions = ( ("can_see_deals", "Can see deals"), ) class Adapter(models.Model): contractor = models.ForeignKey( Contractor, on_delete=models.CASCADE, related_name='adapters_contractors' ) name = models.CharField(max_length=255) slug = models.SlugField(max_length=64) payment_type_group = models.CharField(max_length=64) def __str__(self): return self.name class Meta: db_table = '"processing"."adapter"' class AdapterManager(models.Manager): def get_queryset(self): return super(AdapterManager, self).get_queryset().select_related() class AdapterAccount(models.Model): adapter = models.ForeignKey( Adapter, on_delete=models.CASCADE, related_name='adapter_accounts_adapters' ) objects = AdapterManager() params = JSONField(null=True, blank=True) def __str__(self): return '#{} …
