"Authentication credentials were not provided": how can I make all the views to require log in in DRF?
I'm trying to restrict the post view to only those who have logged in, however after I added the permission to only 'IsAuthenticated' I get this when I go to the url: { "detail": "Authentication credentials were not provided." } Of course, when I go there I have already logged in so something is not working but I'm not sure what. How can I make it so that users can see the posts only if the logged in? This is the view of the post and the log in: class UserLoginAPIView(generics.CreateAPIView): permission_classes = (permissions.AllowAny, ) serializer_class = serializers.UserLoginSerializer def post(self, request, *args, **kwargs): serializer = UserLoginSerializer(data=request.data, context={'request': request}) serializer.is_valid(raise_exception=True) user = serializer.validated_data['user'] token, created = Token.objects.get_or_create(user=user) return Response({"status": status.HTTP_200_OK, "Token": token.key}) class PostAPIView(generics.ListCreateAPIView): """PostViewSet Post API will be used to creating new discussion, listing, and replying to a post """ queryset = Post.objects.all() serializer_class = PostSerializer permission_classes = (IsAuthenticated,) def pre_save(self, obj): obj.created_by = self.request.user def get_queryset(self): """ """ return Post.objects.filter(reply_to__isnull=True) def get(self, request, format=None): content = { 'user': str(request.user), # `django.contrib.auth.User` instance.

Heroku refused connection error 111 for xhtml2pdf to work in Heroku
I have a Django app, with a postgresql database and I have been using xhtml2pdf to render some pdfs. Everything works in production mode but when I deployed to Heroku, the pdf function is not working. I'm guessing it's something to do with BytesIO but I'm stumped.

Formatting multiple BooleanFields as a single Select widget
The database im working with has several boolean fields where only ever one of them should be true at a time. I want to format these as a Select widget, so that I can list the choices and False will be returned for all of the boolean fields except for the selected option. I got each of them individually working as checkboxes (I commented those out), and I was able to make a select widget that is displaying correctly in the view (client_type), but I cannot accomplish the above. Here's the relevant section of my models.py: class DomCase(models.Model): plaintiff = models.BooleanField(default=False, blank=True) defendant = models.BooleanField(default=False, blank=True) class DomCaseForm(ModelForm): client_type = ChoiceField(choices=(('', '----'),('plaintiff', 'Plaintiff'),('defendant','Defendant')), widget=Select(attrs={'class': 'form-control', 'id': 'client_type'})) class Meta: model = DomCase widgets = { #'plaintiff': CheckboxInput(attrs={'class': 'custom-control-input', }), #'defendant': CheckboxInput(attrs={'class': 'custom-control-input', }), } # Dynamically Create Form Fields based on widget details fields = [] for widget in widgets: fields.append(widget) fields = tuple(fields) -
Filtering a django Prefetch based on more fields from the root object
This is similar to other questions regarding complicated prefetches but seems to be slightly different. Here are some example models: class Author(Model): pass class Book(Model): authors = ManyToManyField(Author, through='BookAuthor') class BookAuthor(Model): book = ForeignKey(Book, ...) author = ForeignKey(Author, ...) class Event(Model): book = ForeignKey(Book, ...) author = ForeignKey(Author, ...) In summary: a BookAuthor links a book to one of its authors, and an Event also concerns a book and one of its authors (the latter constraint is unimportant). One could design the relationships differently but it's too late for that now, and in my case, this in fact is part of migrating away from the current setup. Now suppose I have a BookAuthor instance and want to find any events that relate to that combination of book and author. I can follow either the book or author relations on BookAuthor and their event_set reverse relationship, but neither gives me what I want and, if I have several BookAuthors it becomes a pain. It seems that the way to get an entire queryset "annotated" onto a model instance is via prefetch_related but as far as I can tell there is no way, in the Prefetch object's queryset property, to refer to … -
Need help understand the message from upgrading Django
Can someone help me understand what I need to do in response to this error message--or whether anything needs to be done at all? This happened when I decided to upgrade Django from 3.1x to 3.2 (no need to delve into the reasons--a learner's mistakes).

Django unable to locate modules
I set up a Django project using pipenv and have the virtual environment running using pipenv shell. I have been trying to add a few modules to my project including django-acl. However, whenever I $ pipenv install django-acl and then attempt to migrate I get the following message. ModuleNotFoundError: No module named 'djangoacl' At first I thought that django-acl just didn't work but it's done this same thing with every module that I've tried to add since.

Module missing when deploying on Heroku

Performing operations when data is added from admin site in django web application
I have the following models class Order_Ingredient(models.Model): day = models.DateField(auto_now_add=True,blank=True) ingredient = models.ForeignKey(Inventory, on_delete = models.CASCADE) amount = models.IntegerField(help_text = "in grams") class Inventory(models.Model): ingredient_name = models.CharField(max_length=100,unique=True) quantity = models.IntegerField(help_text = "in grams") min_quantity = models.IntegerField(help_text = "in grams") cost_price = models.IntegerField(help_text = "cost per gram") I have registered both the models to the admin site. Now I want to implement the fuctionality that whenever I insert data from the admin site in the Order_ingredient model, I can perform some additional operations like updating the quantity of ingredient referenced by foreign key. One way to do this was to override __init__ in model. But everywhere I searched, it was advised to avoid this method. Is there a workaround to this problem? -
Hidden input field didnot show the correct value which was access from views.py in Django

Pass extra_context directly to django.contrib.auth.urls?
I created this url pattern and I hoped the extra context would be passed on to the views. But the views, which use the correct templates, seem to ignore the extra context. path('accounts/', include('django.contrib.auth.urls'), {'extra_context': {'home_title': settings.HOME_TITLE, 'domain': settings.HOSTNAME}}), I wonder if is is possible at all to pass extra context to the django.contrib.auth.urls or whether I have to create my own views for login/signup/logout in order to use the extra context? -

Django can't find the URL pattern

Optimize collection of paginated REST API data
I need to collect several thousand records from a 3rd party REST API, but each call is limited to 99 records at most. Additionally, the API doesn't return any information about the total number of records or page count, it only returns a boolean "more_records". Having to make several hundred API calls to collect data for a page is obviously very slow, and it's causing one of my routes to timeout. My first thought for optimization is to split out the API calls into asynchronous tasks, but because there's no stopping information besides "more_records" I'm not sure how to handle calling those tasks. I'm using Django for this and I already have Celery set up for other purposes. The route that times out collects and manipulates this and other data and returns it as JSON to populate a gross report. One idea I had was to break down this JSON route so that my gross report's Javascript makes many smaller API calls and manipulates the data itself, but that only solves the timeout since no one call takes too long. The only ways I see to optimize the response time is to reduce the number of API calls or handle … -
Unable to resolve `Bad file descriptor` from django logging
