Django REST Framework, write an API that allows any user to upload an image in jpg or png
It should be possible to easily run the project. docker-compose is a plus users should be able to upload images via HTTP request users should be able to list their images there are three builtin account tiers: Basic, Premium and Enterprise: users that have "Basic" plan after uploading an image get: a link to a thumbnail that's 200px in height users that have "Premium" plan get: a link to a thumbnail that's 200px in height a link to a thumbnail that's 400px in height a link to the originally uploaded image users that have "Enterprise" plan get a link to a thumbnail that's 200px in height a link to a thumbnail that's 400px in height a link to the originally uploaded image How can I create those accounts? I've done just users and they can upload images. -
SMTP Authentication error with Gmail and Django
I have been facing an issue for a while now. I need my Django app to send password reset emails to users whenever they request for it. I have configured the SMTP correctly and even tested the connection using GMass and it seems to work fine. However, it does not work on my Django app. I have enabled 2FA and I'm using an App Password. This is the error that it throws at me.

What is the simplest way to handle django ORM access e.g <model>__<model>, select_related
I want to implement a soft delete to model. The problem is that project is big and i need to find all filtering and access expressions to target model and edit it. Is there a workaround to handle them on target model side? -
Django - struggling with excessive queries
I need to implement a website menu where every root item can have a dropdown with some more items, and I need to do that using some django models and without any third party tools like mptt. So it will be a tag. So here are the models: class Menu(models.Model): name = models.CharField(max_length=150) class MenuElement(models.Model): name = models.CharField(max_length=100) menu = models.ForeignKey('Menu', on_delete=models.CASCADE) parent = models.ForeignKey('self', null=True, blank=True, on_delete=models.CASCADE, related_name='children') And here is the function that's supposed to do the trick: def draw_menu(menu_name): menu_elements = MenuElement.objects.filter(menu__name=menu_name).select_related('parent') for element in menu_elements: if not element.parent: element.children_list = element.children.all() And here comes the problem. If I get a list of all children of a menu element, it's super easy to display the thing on the web page. But if I leave it like this, there will be an additional query for every root element (to get the children), so 10 elements = 10 queries. And select related cannot really help in here, at least I don't see how to utilize it. 10 queries for a menu is not an option, even 2 is too much, is it possible to do the whole thing using one? Maybe if I redesign the model somehow? -
django-debug-toolbar configure INTERNAL_IPS for docker, compatible ip6
I just got django-debug-toolbar to work in Docker, but with a bit of a hack. The official instructions say if DEBUG: import socket # only if you haven't already imported this hostname, _, ips = socket.gethostbyname_ex(socket.gethostname()) INTERNAL_IPS = [ip[: ip.rfind(".")] + ".1" for ip in ips] + ["127.0.0.1", "10.0.2.2"] However I saw no toolbar. In my template html I printed {{request.META.REMOTE_ADDR}} and noticed that it was an IP6 address. So I changed the above INTERNAL_IPS logic to if DEBUG: hostname, _, ips = socket.gethostbyname_ex (socket.gethostname()) ips = [ip[:ip.rfind(".")] + ".1" for ip in ips] INTERNAL_IPS += ips INTERNAL_IPS += ['::ffff:'+ip for ip in ips] This works but it feels hacky. Is there a better way to do this? -
find alternative to celery-beat to run slow tasks
I have a problem with a celery task that I have to run every 30 seconds. The task consists of connecting through ModbusTCP to a system to read some values. The problem is that I have to read these values from several systems and in 30s it is not able to finish the execution of all of them. As at the moment I do it is through celery-beat I execute a task that consists of a loop that goes through all the systems to which I have to connect to read the data. The connection attempt sometimes takes a while and that is what causes that in 30 seconds I don't have time to execute the whole loop. Is there any alternative to celery-beat that can fit the functionality I am looking for? Thanks! Try to find a solution for the problem or any alternative to solve my situation -
Django REST Framework Viewset Executes Actions Multiple Times and Shows 'None' for GET Requests

Inbuilt password validator for password reset Django

Currently the two password fields are visible and when I change the password, it is working fine but I need to include the password validation that is offered by Django which will check for these below conditions.

Why custom clients might be ignored by unittest in Django?
Exploring Unittest, can't figure out why these tests ignore custom clients prepared in setUp() method and use the built-in self.client (== self.guest_client).

I have a problem with path image in django, When I put in the path from the model (item.img) and start the server, I don't see the image because the image path doesn't contain /media/.but if I add /media/ before {{item.url}} everything is going right I can't figure out what I'm doing wrong My code: -setting.py STATIC_URL = '/static/' STATIC_ROOT = os.path.join(BASE_DIR,'static') # Default primary key field type # https://docs.djangoproject.com/en/4.2/ref/settings/#default-auto-field DEFAULT_AUTO_FIELD = 'django.db.models.BigAutoField' AUTH_USER_MODEL = 'authentication.CustomUser' MEDIA_URL = '/media/' MEDIA_ROOT = os.path.join(BASE_DIR,'media') -urls.py urlpatterns = [ path('admin/', admin.site.urls), path('',include('items.urls')), ] if settings.DEBUG: urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) urlpatterns += static(settings.STATIC_URL, document_root=sett -html <div class="main__column"> <div class="main__item item"> <div class="item__img"> {% for img in p.image_set.all %} {{img.main_image}} <img src="{{img.main_image}}" alt=""> {%endfor%} </div> <div class="item__body"> <div class="item__name">{{p.name}}</div> <div class="item__descriptions">{{p.descriptions}}</div> <div class="item__price">{{p.price}}</div> <div class="item__in_stock">{{p.in_stock}}</div> </div> </div> </div> I have looked for a solution to the problem in other forums. I am waiting for someone's help -
In Django, can you filter a queryset by a parent (uses ForeignKey field) model's field value?
Let's say you have models defined for Transaction, Category, and TransactionDetail, like so: class Transaction(models.Model): details = models.ForeignKey(TransactionDetails, verbose_name="Transaction Details", on_delete=models.PROTECT, default='',null=True) category = models.ForeignKey(Category, verbose_name="Transaction Category", on_delete=models.PROTECT, default='') class Category(models.Model): name = models.CharField(max_length=255, verbose_name="Category Name", default="") class TransactionDetails(models.Model): value = models.CharField(max_length=255, verbose_name="Transaction Detail", default="") In views.py I am trying to figure out how to filter TransactionDetails objects that are attached to a Transaction.details field AND have a specific Transaction.Category.name. In other words, I'd like to return a queryset of TransactionDetails that are related to Transaction objects with a category.name of "uncategorized". I understand how to use the objects manager filter for the other way around: uncatTransactions = Transaction.objects.filter(category__name="Uncategorized") But am unsure how this would be done for TransactionDetails: uncategorizedTrxDetails = TransactionDetails.objects.filter(referenceToParentUsingForeignKey__category__name="Uncategorized") -
Django CSRF token missing in form submission despite including it
I am working on a Django project where I have a form to verify a phone number using Twilio's API. However, I'm encountering an issue where the CSRF token is missing in the form submission, resulting in a "CSRF token missing" error. I have already included the {% csrf_token %} template tag inside the element in my HTML template. I have also verified that the django.middleware.csrf.CsrfViewMiddleware middleware is enabled in my Django settings. @login_required def verify_phone_number(request): if request.method == 'POST': # Code to initiate phone number verification using Twilio's API # Code to Return an HTTP response with the HTML content when verification request wasnt sent html_content = """ return HttpResponse(html_content) else: # Return an HTTP response with the HTML content html_content = """ <!DOCTYPE html> <html> <head> <title>Verify Phone Number</title> </head> <body> <h1>Verify Your Phone Number</h1> <form method="post"> {% csrf_token %} <label for="phone_number">Phone Number:</label> <input type="text" id="phone_number" name="phone_number" required> <button type="submit">Verify</button> </form> </body> </html> """ return HttpResponse(html_content) -
How to show comment on blogpost with slug instead of pk
I want to show the comment underneath an article, but I use a slug instead of a pk. I got the following error: IntegrityError at /blogpost-2/comment/ NOT NULL constraint failed: blog_comment.post_id This is my code: #models.py `class Comment(models.Model): post = models.ForeignKey(Post, related_name="comments", on_delete=models.CASCADE) name = models.CharField(max_length=255) body = models.TextField() date_added = models.DateTimeField(auto_now_add=True) def __str__(self): return '%s - %s' % (self.post.title, self.name)` #views.py `class AddCommentView(CreateView): model = Comment form_class = CommentForm template_name = "add_comment.html" #fields = '__all__' def form_valid(self, form): form.instance.post_id = self.kwargs['pk'] return super().form_valid(form) success_url = reverse_lazy('blog')` #urls.py `from django.urls import path from . import views from .views import BlogView, ArticleView, CategoryView, AddCommentView urlpatterns = [ path('<slug:slug>', ArticleView.as_view(), name='blogpost'), path('blog/', BlogView.as_view(), name='blog'), path('categorie/<str:cats>/', CategoryView, name='category'), path('<slug:slug>/comment/', AddCommentView.as_view(), name='add_comment'), ]` #template add_comment.html `{% extends 'base.html' %} {% load static %} {% block content %} <h1>Voeg een reactie toe..</h1> <div class="form-group"> <form method="POST"> {% csrf_token %} {{ form.as_p }} <button class="btn btn-primary">Voeg toe</button> </form> </div> {% endblock %}` I tried this code, but doesn't work... def form_valid(self, form): form.instance.post_slug = self.kwargs['slug'] return super().form_valid(form) -
