Handling form fields in django for logged in user
Im trying to handle the existing name of a Category, so that users wont be allowed to create 2 categories with the same name, but at the moment its taking all categories from the database, not only for the logged-in user. I dont know how and where to implement request.user. I`m building an inventory app where everyone creates their own categories and adds items. Thank you.

Django dj-rest-auth (django-allauth) redirection doesn't work, however, LOGIN_REDIRECT_URL is set
I'm using Django 4.1 (Djoser doesn't work with 4.x) and dj-rest-auth (if I'm not mistaken, registration is provided by django-allauth module). What am I trying to achieve is getting new user to a profile creation page ('/api/v1/new_hero/' endpoint), right after he signs up. Without any email verification, just right into it. But for now, with all theese settings, after registration, django keeps the user on the same ('auth/registration/') page with tokens demonstration and other stuff. By the way, situation keeps similar with loginning. How am I supposed to direct the user to a target page? settings.py: DEFAULT_AUTO_FIELD = 'django.db.models.BigAutoField' REST_USE_JWT = True JWT_AUTH_COOKIE = 'jwt-auth' SITE_ID = 1 LOGIN_REDIRECT_URL = '/api/v1/new_hero/' ACCOUNT_SIGNUP_REDIRECT_URL = '/api/v1/new_hero/' ACCOUNT_AUTHENTICATED_LOGIN_REDIRECTS = True ACCOUNT_EMAIL_VERIFICATION = 'none' items/urls.py urlpatterns = [ path('items/', ItemsListCreateView.as_view(), name='list_items'), path('items/<int:pk>/', ItemDetailView.as_view(), name='update_item'), path('heroes/', HeroListView.as_view(), name='list_heroes'), path('new_hero/', HeroCreateView.as_view(), name='create_hero'), path('heroes/<int:pk>/', HeroDetailView.as_view(), name='update_hero'), path('classes/', HeroClassListCreateView.as_view(), name='list_classes'), path('weapons/', WeaponClassListCreateView.as_view(), name='list_weapons'), # path('reg/', Registration.as_view(), name='custom_registration'), ] I tryied different django-allauth settings, checked correctness of INSTALLED_APPS, AUTHENTICATION_BACKENDS and other sections of settings.py, and it all end up here, with me writing a question. -
s3 bucket does not collect created pdfs in media folder django/aws
I just deployed my django application to a beanstalk server linked to an s3 bucket in the aws console. In my application pdfs from each post are created and forwarded to the media folder in the subfolder "postings". However, in the bucket no such folder is created and the pdfs also don't show up anywhere else. only the uploaded images of the post is there. How do I get the pdfs there? also, I get an ValueError now for the Image in the PDF (which is the uploaded image, and which was working just fine before adding the bucket). How do I get it to work again? I think both problems are due to some connection missing... This is my first project deploying to aws. Please help me out with a little explanation. Here is the code of the created upload and pdf: views.py def post_create(request): if request.method == 'POST': form = PostCreateForm(request.POST, request.FILES) if form.is_valid(): form.cleaned_data['num_post'] = Post.objects.count() + 1 Post.objects.create(**form.cleaned_data) else: form = PostCreateForm() return render(request, 'index.html', {'form': form}) def upload(request): if request.method == 'POST': image = request.FILES.get('image_upload') caption = request.POST['caption'] num_post = Post.objects.count() + 1 new_post = Post.objects.create(image=image, caption=caption, num_post=num_post) new_post.save() # create pdf buffer = io.BytesIO() … -
Problem with running maintenance mode in my Django and React apps that are stored on Azure Web App for Containers?
I have deployed Django and React application on Azure. I am using Web Application for Containers. One Web App is for Django and second one is for React (CORS headers are properly confiured, both apps are connected to each other). Docker images are stored on Azure Container Registry. I am looking for an option to switch both apps to Maintenance mode when doing some maitenance things or deploying. I was thinking abouting creating extra env variable called MAITENANCE_MODE in Application settings where I can switch manually from false to true and then it switches the mode on websites automatically. Another idea would be to create some webjobs but I am not familiar with these topics and I am asking for an advice on how to do it or at least where to look for such solution. -

Django modeltranslation and AutoSlugField
I'm struggling with combination of AutoSlugField (from django-extensions) and ModelTranslation. class Article(models.Model): title = models.CharField(max_length=255, default="") slug = AutoSlugField( populate_from=[ "title", ], overwrite=True, ) Make perfect sense without model translation. Unfortunately, if title and slug fields are translatable it does not work out of the box. The migration file created by ModelTranslation contains description for AutoSlugField: migrations.AlterField( model_name="article", name="slug_de", field=django_extensions.db.fields.AutoSlugField( blank=True, editable=False, null=True, populate_from=["title"] ), ), migrations.AlterField( model_name="article", name="slug_en", field=django_extensions.db.fields.AutoSlugField( blank=True, editable=False, null=True, populate_from=["title"] ), ), But slug_en should be based on title_en and slug_de should be based on title_de. Is it possible to enforce such behavior? -

How to update ManyToManyField when source model is deleted?

Using Django JWT authorization for FastAPI endpoint
I have a Django app where I use SIMPLE_JWT to authenticate users. I use Django to work with the admin panel, in addition, I use the Django rest framework to transfer data to the React frontend application. During authorization, the React application receives a JWT token, which is then passed along with any requests to Django rest framework endpoints. Now there is a need to create a new FastAPI endpoint. Is there any way to make FastAPI use the same JWT tokens that the Django application accepts (and creates) to check whether the user is authorized and has access rights to the FastAPI endpoint? How to do it most correctly? -

Safely store data from GET request - Django
Alright, Let's say we need to create a website with Django where people can book a lodge for the weekends. We add a search form on the homepage where people can fill in the check-in and check-out date to filter for all available lodges. We use a generic Listview to create an overview of all the lodges and we overwrite the queryset to grab the search parameters from the GET request to create a filtered view. views.py class ListingsView(ListView): """Return all listings""" model = Listing template_name = 'orders/listings.html' def get_queryset(self): """ Visitors can either visit the page with- or without a search query appended to the url. They can either use the form to perform a search or supply an url with the appropriate parameters. """ # Get the start and end dates from the url check_in = self.request.GET.get('check_in') check_out = self.request.GET.get('check_out') queryset = Calendar.objects.filter( date__gte=check_in, date__lt=check_out, is_available=True ) return queryset Now this code is simplified for readability, but what I would like to do, is store the check-in and check-out date people are searching for.
