How do I reorder a list of objects manually using Django, Python, (and possibly Javascript)?
Here is my code. models.py from django.db import models class Photo(models.Model): file = models.ImageField(upload_to='media/images') class Album(models.Model): title = models.CharField(max_length=100) photos = models.ManyToManyField(Photo,related_name="photos",blank=True) admin.py from django.contrib import admin from .models import Photo, Album # Register your models here. class AlbumAdmin(admin.ModelAdmin): list_display = ("title","published") filter_horizontal = ("photos",) def formfield_for_manytomany(self, db_field, request, **kwargs): if db_field.name == "photos": kwargs["queryset"] = Photo.objects.order_by("-id") return super(AlbumAdmin, self).formfield_for_manytomany(db_field, request, **kwargs) admin.site.register(Photo) admin.site.register(Album, AlbumAdmin) views.py from django.shortcuts import render from django.conf import settings from .models import Photo, Album # Create your views here. def album(request, album_title): album = Album.objects.get(title=album_title) context = { "album":album, } return render(request, "photos/album.html", context) I am trying to achieve a page that shows the photos in each album and has a drag-and-drop function that allows a manual re-ordering of the photos in each album.

Reorder django core functionality
I faced with the problem of Django multi site project. Each site can handle multiple languages. Project handle languages by url and we don’t use default language prefix. For example Site one: root / specify russian language and /en specify english version of site (default language is russian) Site two: root / specify english language and /ru specify russian version of site (default language is english) Django has a problem. Framework cache resolver and store prefixes for some sites. When I begin to use different default languages for different domains I was confuse with wrong prefixes. I must change behavior of django get_resolver() function becouse of hist @functools.lru_cache decorator (this is django file): def get_resolver(urlconf=None): if urlconf is None: urlconf = settings.ROOT_URLCONF return _get_cached_resolver(urlconf) @functools.lru_cache(maxsize=None) def _get_cached_resolver(urlconf=None): return URLResolver(RegexPattern(r'^/'), urlconf) Can I do something to disable cache? Or make cache depend of site? I tried to reorder function in django core module My solution is: from django.urls.resolvers import URLResolver, RegexPattern @functools.lru_cache(maxsize=None) def get_resolver_for_site(site_id, urlconf): return URLResolver(RegexPattern(r'^/'), urlconf) def _get_cached_resolver_for_site(urlconf=None): return get_resolver_for_site(get_site().id, urlconf) @receiver(post_save, sender=SiteSettings) def clear_url_resolver_cache(sender, **kwargs): get_resolver_for_site.cache_clear() resolvers._get_cached_resolver = _get_cached_resolver_for_site So I defined custom function, that return url resolver and cache it depend of site.

Django Template - If both IF statements are empty
I know how to use an if statement in django, and if the if is empty. Like this: {% if results %} <!-- True --> {% else %} <!-- False --> {% endif %} Now how do I do this if I have more than on if statement like this: {% if users %} <!-- Users is true --> {% endif %} {% if results %} <!-- Results is true --> {% endif %} <!-- Problem: --> {% if results and users %} <!-- Both are true --> {% else %} <!-- Do only if both are false --> {% endif %} So I tried using if and but it didn't work, even if one existed it still ran the stuff in the else. So how do I make sure it checks if both statements are false, and only if they are both false, to run the else. Any suggestions? -

FOREIGN KEY constraint failed - Django
So I'm trying to make a delete route for my API but I'm encountering a problem. Whenever I hit the delete route I get an error which is django.db.utils.IntegrityError: FOREIGN KEY constraint failed. I'm trying to delete a model if the delete route is hit. I have done makemigrations and migrate but there were no changes. Example of my code is like this: class RandomAPIView(APIView): def delete(self, request, id, format=None): product = Product.objects.get(pk=id) product.delete() return Response({'Success':'Product has been deleted'}) product in models.py class Product(models.Model): name = models.CharField(max_length=200) category = models.ForeignKey(Category, on_delete=models.CASCADE, blank=True, null=True) def __str__(self): return self.name -
Django Iterating through Queryset and taking user input

Method that count minutes from post publishing
I'm writing small social web application using Django. So I need to count minutes from post publishing (e.g like it looks in Twitter) I tried to do something like this: class Post(models.Model): # post model fields @property def publish_date(self): if self.date >= (timezone.now() - datetime.timedelta(hours=1)): return f'{timezone.now().minute - self.date.minute} minutes ago' else: return self.date And use it into HTML like this: <span id="post_date">{{ p.publish_date }}</span>, where p is post instance But sometimes it's returns negative values (like in example below) So how can I correctly realize this? -

When trying to set a django session value, I have Type Error "Object of type Decimal is not JSON serializable" while it is a string value. Why?
I would like to record a discount code from input users. I have set up a UserDiscountForm(forms.Form) (in forms.py). In the view, I would like to record in the session, the data that a user inputs. But when I try to set the value (after checking that the form is valid), it raises a TypeError: "Object of type Decimal is not JSON serializable". I don't understand because the data I am trying to save is a string value. In addition, I am able to save other data in the session (a shopping cart and a shipping address) the similar way and it works perfectly. forms.py (user_input is a string) from django import forms class UserDiscountForm(forms.Form): user_discount = forms.CharField(label='discount code ?', label_suffix="-->", help_text="Entrez discount code", required=False) def clean_user_discount(self, *args, **kwargs): user_input = self.cleaned_data['user_discount'] if len(user_input) > 4: raise forms.ValidationError("longueur > 4") else: print(type(user_input)) return user_input views.py (form.cleaned_data['user_discount'] is a string) from django.shortcuts import render, get_object_or_404 from django.http import JsonResponse from . basket import Basket from store.models import Product from discount.forms import UserDiscountForm def basket_summary(request): basket = Basket(request) form = UserDiscountForm(request.POST or None) context = {'basket':basket, 'form':form} if request.method == 'POST': if form.is_valid(): print(form.cleaned_data['user_discount']) print(type(form.cleaned_data['user_discount'])) request.session['discount_code'] = form.cleaned_data['user_discount'] form = UserDiscountForm() context … -

Django - Sending POST request to another webiste - lack of headers
I'm currently struggling to integrate third-party payment system with my django website. When sending POST request along with form data to payment site it responds with an 403 Forbidden error - CSRF verification failed. You are seeing this message because this HTTPS site requires a 'Referer header' to be sent by your Web browser, but none was sent.. I've installed cors_headers, configured it as suggested in documentation and set CORS_ALLOW_ALL_ORIGINS temporarily to True. When inspecting network tab I've noticed that when requests are within same domain requests are included: same-origin-headers But when sending POST request to the third-party site, they are not: cross-origin-headers I'm including my django view as well as html form: Django view: def payment_loading(request): if request.method == 'GET': order = Order.objects.get(session=request.session.session_key) context = { 'order': order, } return render(request, 'payment_loading.html', context) HTML form: <h1>Processing payment</h1> <form name="dotpay_post" action="https://ssl.dotpay.pl/test_seller/" method="POST"> {% csrf_token %} <input name="api_version" value="{{ order.dotpay_object.api_version }}" type="hidden"> <input name="id" value="{{ order.dotpay_object.shop_id }}" type="hidden"> <input name="amount" value="{{ order.dotpay_object.amount }}" type="hidden"> <input name="currency" value="{{ order.dotpay_object.currency }}" type="hidden"> <input name="description" value="{{ order.dotpay_object.description }}" type="hidden"> <input name="control" value="{{ order.dotpay_object.control }}" type="hidden"> <input name="url" value="{{ order.dotpay_object.url }}" type="hidden"> <input name="type" value="{{ order.dotpay_object.type }}" type="hidden"> <input name="urlc" value="{{ order.dotpay_object.urlc }}" type="hidden"> <input … -

django complete email verification
before this question is going to be marked as a possible duplicate, I want to address a few things. I want to make sure that users have a single email field called email. They also have an is_verified field to indicate whether the email has been verified. There are a few pitfalls in most of the email verification implementations. Lets say that an user creates an account and has an unverified email. Lets say that the user does not actually own the email, though. Now, the actual owner of the email enters the site. But, as the email is already saved in the database, we get an integrity error - that the email is already in use. Thus, any scammer can enter a random email and claim it. This reduces the user experience. How can this be avoided so as to provide a complete email verification system? ( One where the actual owners can claim their emails) thanks a lot! -
