Django how a user can add a new attribute to a model from template
I have the following model : models.py : class Product(models.Model): name = models.CharField(blank=False, max_length=255) description = models.TextField() class Ingredients(models.Model): ingredients = models.ForeignKey(Product, related_name='ingredients', on_delete=models.CASCADE, null=True) salt = models.IntegerField(default=0) pepper = models.IntegerField(default=0) views.py : def productdetails(request, product_pk): product = get_object_or_404(Product, pk=product_pk) ingredients = get_object_or_404(Ingredients, ingredients_id=product_pk) salt = ingredients.salt pepper = ingredients.pepper if request.method == 'POST': form = IngredientsForm(request.POST) newvalue = form.save(commit=False) newvalue.user = request.user newvalue.save() return render(request, 'xxx.html', {'product': product, 'form': IngredientsForm, 'salt': salt, 'pepper': pepper}) return render(request, 'xxx.html', {'product': product, 'iform': IngredientsForm, 'salt': salt, 'pepper': pepper}) def updateproduct(request, product_pk): ingredients = get_object_or_404(Ingredients, ingredients_id=product_pk) form = IngredientsForm(request.POST or None, instance = ingredients) salt = ingredients.salt pepper = ingredients.pepper if form.is_valid(): form.save() products = Product.objects.filter() return render(request, 'xxx.html', {'products': products}) return render(request, 'xxx.html', {'form': form, 'salt': salt, 'pepper': pepper, 'product_pk': product_pk}) def createingredients(request, product_pk): if request.method == 'POST': ingredients = get_object_or_404(Ingredients, ingredients_id=product_pk) form = IngredientsForm(request.POST or None, instance=ingredients salt = ingredients.salt pepper = ingredients.pepper # here should be the code return render(request, 'xxx.html', {'ingredients': ingredients, 'product_pk': product_pk}) In template: <div class="container"> <strong>Ingredients:</strong> <b>Salt: </b>{{ salt }} g <br> <b>Pepper: </b>{{ pepper }} g <br> <br> Update ingredients: {% if error %} <div class="alert alert-danger" role="alert"> {{ error }} </div> {% endif %} … -

Django+React: What is the bet way to properly implement authentication and security on API requests from React to Django backend
I am working on a Django+React project. My React app is my only UI renderer (which means no template or any markup is being served by Django), while my Django app is only used for serving APIs for me to access my database resources. On a particular React page, I have login and test buttons that send requests to a DRF API in my Django backend. Login API View class AuthLogin(generics.GenericAPIView): serializer_class = LoginSerializer authentication_classes = [SessionAuthentication] permission_classes = () def get(self, request): user = request.user if not user and not user.is_authenticated or user.is_anonymous: return Response( { "status": True, "message": "Login page accessed" }, status=status.HTTP_200_OK ) else: return Response( { "status": False, "message": "You are currently logged in" }, status=status.HTTP_400_BAD_REQUEST ) def post(self, request, *args, **kwargs): res = [] res_stat = status.HTTP_401_UNAUTHORIZED serializer = self.get_serializer(data=request.data) serializer.is_valid(raise_exception=False) validated_data = serializer.validated_data if validated_data: user = dj_auth(username=request.data.get('username'), password=request.data.get('password')) if user and user.is_authenticated and not user.is_anonymous: auth_login(request, user) res_stat = status.HTTP_200_OK res = { "status": True, "message": "Login successful!", "login": { "date_time": timezone.now(), "user": { 'id': user.id, 'first_name': user.first_name, 'last_name': user.last_name, 'email': user.email, } } } else: res_stat = status.HTTP_401_UNAUTHORIZED res = { "status": False, "message": "Invalid username and/or password" } else: res_stat = … -
excluding based on related field's count
I have classic title and entry models where title is foreignkey in entry model. I use users model's default first_name field to suspend users, so if a user is suspended then the first_name field is set to blocked. I also have a model to let user block eachother: class Block(models.Model): blocker= models.ForeignKey("auth.user",on_delete= models.CASCADE,related_name="blocker") blocked= models.ForeignKey("auth.user",on_delete= models.CASCADE,related_name="blocked") What I want to do is to display titles while excluding titles if there are no entries left beloging to the title after exlusion of blocked and suspended users. In other words filtering titles if related entry count is > 0 after exclusions. I've been using the code below to solve this: title= Popular.objects.all().order_by("-rating") titles= [] followed_count= None paginator = Paginator(title, 1) page = request.GET.get('page', 1) try: entries2 = paginator.page(page) except PageNotAnInteger: entries2 = paginator.page(1) except EmptyPage: entries2 = paginator.page(paginator.num_pages) page_list = entries2.paginator.page_range for title in entries2: if request.user.is_authenticated: followed_count= Entry.objects.filter(user__followed__follower=request.user,title=title.title,created_date__gte=date_from).exclude(user__last_name="blocked").count() blocked_count= Entry.objects.filter(user__blocked__blocker=request.user,title=title.title,created_date__gte=date_from).exclude(user__last_name="blocked").count() else: blocked_count= 0 suspend_count= Entry.objects.filter(user__last_name="blocked",title=title.title,created_date__gte=date_from,).count() amount= Entry.objects.filter(title=title.title,created_date__gte=date_from).count() amount -= blocked_count + suspend_count if amount == 0: continue titles.append({"title":title.title,"url":title.title.title_url,"rating":title.rating,"title_id":title.title_id,"amount":amount,"followed_count":followed_count} But if there are titles with no entries it causes the paginator to create empty pages, I also do not want to put the pagination code to the end as I don't want … -
Django 3.1 asgi server timeout connecting to itself inside async view
Got an issue trying to connect from an async view in Django 3.1 to a sync view served by the same asgi server. Doing this in normal wsgi development server works, but not in an asgi server. Which seems kind of weird. Probably I misunderstood on how asgi works :). Here's a link on how to reproduce this: All steps to reproduce this. Here are just the views causing the problem. Maybe someone is able to tell immediately what I'm doing wrong by just looking at those: import httpx from django.http import JsonResponse def sync_api_view(request): payload = {"foo": "bar"} return JsonResponse(payload) def sync_aggregation_view(request): responses = [] r = httpx.get("http://127.0.0.1:8000/sync_api_view/") responses.append(r.json()) result = {"responses": responses} return JsonResponse(result) The "sync_aggregation_view" is the one that works in wsgi but not via asgi. -

Shorten condition variable in Django template using with
Hey I am trying to set a variable in a Django template on a condition and also within a for loop (which is why I can't do it directly in the views). The condition I have is this: {% if message.sender == request.user %} {% contact=message.receiver %} {% else %} {% contact=message.sender %} {% endif %} I thought about putting with in each condition but I would have to have a copy of the same HTML code in each if/else part because you need to have an {% endwith %}, like so: {% if message.sender == request.user %} {% with contact=message.receiver %} <p>some html code</p> {% endwith %} {% else %} {% contact=message.sender %} <p>some html code</p> {% endwith %} {% endif %} So I would like to shorten it like that to be able to use with but it doesn't seem to work: {% with contact=(message.sender, message.receiver)[message.sender == request.user] %} Any idea how I could achieve this? -
Using QuerySet.union() in ModelAdmin.formfield_for_manytomany() breaks selection widget
Not sure what I am doing wrong here: I tried to use QuerySet.union() to combine two querysets (for the same model) inside ModelAdmin.formfield_for_manytomany(). However, when the form is saved, the entire queryset is selected, regardless of the actual selection made. Pleas consider the minimal example below, based on the standard Django Article/Publication example. Here's what happens when I add a new Article in the admin, without selecting any publications: Before "Save" (nothing selected) After "Save" (everything is selected) These images were created using the following minimal example: from django.db import models from django.contrib import admin class Publication(models.Model): pass class Article(models.Model): publications = models.ManyToManyField(to=Publication, blank=True) class ArticleAdmin(admin.ModelAdmin): def formfield_for_manytomany(self, db_field, request, **kwargs): if db_field.name == 'publications': # the following query makes no sense, but it shows an attempt to # combine two separate QuerySets using QuerySet.union() kwargs['queryset'] = Publication.objects.filter(id__lt=3).union( Publication.objects.filter(id__gt=2)) return super().formfield_for_manytomany(db_field, request, **kwargs) admin.site.register(Publication) admin.site.register(Article, ArticleAdmin) The initial queryset for the publications field is filtered using formfield_for_manytomany, as described in the docs. The actual query in this example makes no sense, but the point is that QuerySet.union() messes things up (it works normally if you remove the union()). Am I using QuerySet.union() the wrong way,or is this expected behavior, given … -
Image carousel, converting p5.js to Django?
I'm a beginner with Django and would appreciate getting some directions / tips of tutorials for the following scenario: User sees image 1 on home page. When they click a button, it changes to image 2, then after next click to image 3 etc. These images can come from JSON (preferably) or image folder in my database. I have been looking into some AJAX tutorials (like https://www.pluralsight.com/guides/work-with-ajax-django) and I start to understand the basic structure of Django, however so far I find it a bit difficult to understand how to update the image like this. Just in case, I'll illustrate how I got it working in P5.js with array and index: var index = 0; var imageData; var imgList = []; var indexMax; function preload() { loadJSON("img.json", resultLoaded); console.log("JSON is loaded") } function resultLoaded(data) { imageData = data; console.log(imageData) console.log(imageData.length) indexMax = imageData.length; for (i = 0; i < indexMax; i++) { url = imageData[i]["source"]; imgList.push(loadImage(url)); } } function setup() { createCanvas (w, h); setupButtons(); } function setupButtons() { buttonA = select("#goodButton"); buttonA.mousePressed(function() { index = index + 1; if (index == indexMax) { index = index - indexMax; } }); (etc.) Warm thanks for any help! -

Loading dynamic initial data in runtime in Django app
The issue: I have some models structure in my Django app: Company Category (category has fk relation to companies) Payment (it doesn't matter in this context, just for the big picture, every payment has a category and a company) Users can create companies. After that action, I want to load initial data for the most common categories of payments (there are about 30-40 categories, so it's not a good idea to hardcode it). What I've tried to do: I thought about Django's fixtures, but we can't modify them in runtime (to set fk relation to the exact company). So, how to load prepared fixtures with dynamic data and do it in runtime? Or maybe there is another way and another tool to implement this feature? -

It's a single layered json and it is easily parsed when returned to server with result: <QueryDict: {'csrfmiddlewaretoken': ['6aTZ7xey90sczae15069ZlbIiE7gVWW69RyeJBptUxadbgnBo8t8R0Nskg8S8Jzb', '6aTZ7xey90sczae15069ZlbIiE7gVWW69RyeJBptUxadbgnBo8t8R0Nskg8S8Jzb'], 'days': ['Mon', 'Wed'], 'no_weeks': ['1']}> Then when using a nested dictionary with data: {'form':frm.serialize(),'additional_data':12,'csrfmiddlewaretoken' : $("input[name=csrfmiddlewaretoken]").val()}``` I get: <QueryDict: {'form': ['csrfmiddlewaretoken=IF2D4vTBjaQSsrE4oY3Lb36jekPB5nZbLmHSGz4w4HyT4xNEH6qK3II3gWQdiaCg&days=Mon&days=Thu&no_weeks=2&csrfmiddlewaretoken=IF2D4vTBjaQSsrE4oY3Lb36jekPB5nZbLmHSGz4w4HyT4xNEH6qK3II3gWQdiaCg'], 'additional_data': ['12'], 'csrfmiddlewaretoken': ['IF2D4vTBjaQSsrE4oY3Lb36jekPB5nZbLmHSGz4w4HyT4xNEH6qK3II3gWQdiaCg']}> What i've tried I have attempted with use of this answer to use urllib to parse the form section of the data into a separate variable. Like so: x = parse_qs(urllib.parse.urlparse(request.POST['form']).query) This returns an empty dicitonary. Code HTML <form method="post" id="replicate_form"> [..more code] </form> Javscript function send_replication_data() { var frm = $('#replicate_form') var form_server_response = submit_formdata(frm) } // parent function to handle replcation form saving $('#create_replicate_booking_button').on('click', function() { send_replication_data() }); // submit booking data ajax function submit_formdata(frm) { var tmp = $.ajax({ type: frm.attr('method'), async:false, url: window.location.href, data: {'form':frm.serialize(), 'additional_data':12, 'csrfmiddlewaretoken' : $("input[name=csrfmiddlewaretoken]").val()} }); return tmp.responseJSON; } Possibly I could somehow make use of whatever Django is doing in it's middleware to a parse the form data in … -
Comparing ForeignKey Values In A Form Values Outside The Form
I'm displaying a table. Among the static information on the table I want to insert the checkbox 'read' which is attached to a single User/Book pair. I cannot figure out how to compare the current book in my outter loop with the book in my inner form loop in order to output the checkbox matching the book. I have tried many ways of accessing form.book.id, id being the book's id in the DB, not an attribute of the Book model. I think I may have to add an id field to my UserBookData model. class UserBookData(models.Model): user = models.ForeignKey(Users, related_name='user_book_data', on_delete=models.CASCADE) book = models.ForeignKey(Book, on_delete=models.CASCADE) read = models.BooleanField() {% for book in user.books.all %} <tr> <td>{{ book.name }}</td> <td>{{ book.author}}</td> {% for item in form %} # this -> {% if item.book.id == book.id %} <td>{{ item.read }}</td> {% endif %} {% endfor %} Thank you. -
stripe coupon code functionality in django
This is my dj-stripe view function for making a subscription, now I want to add a coupon functionality to it where a customer can enter a coupon code and get 15% off the subscription. How can I implement it in this function? def create_sub(request): if request.method == 'POST': # Reads application/json and returns a response data = json.loads(request.body) payment_method = data['payment_method'] stripe.api_key = djstripe.settings.STRIPE_SECRET_KEY payment_method_obj = stripe.PaymentMethod.retrieve(payment_method) djstripe.models.PaymentMethod.sync_from_stripe_data(payment_method_obj) try: # This creates a new Customer and attaches the PaymentMethod in one API call. customer = stripe.Customer.create( payment_method=payment_method, email=request.user.email, invoice_settings={ 'default_payment_method': payment_method } ) djstripe_customer = djstripe.models.Customer.sync_from_stripe_data(customer) request.user.customer = djstripe_customer # At this point, associate the ID of the Customer object with your # own internal representation of a customer, if you have one. # print(customer) # Subscribe the user to the subscription created subscription = stripe.Subscription.create( customer=customer.id, items=[ { "price": data["price_id"], }, ], expand=["latest_invoice.payment_intent"] ) djstripe_subscription = djstripe.models.Subscription.sync_from_stripe_data(subscription) request.user.subscription = djstripe_subscription request.user.save() return JsonResponse(subscription) except Exception as e: return JsonResponse({'error': (e.args[0])}, status =403) else: return HTTPresponse('requet method not allowed')
