Django - How to make methods in a Model Manager automatically called?
I'm building a Cart model and a BooksInCart model, I want the book_quantity field in a cart model update automatically each time when I add books into a cart. The update_cart_quantity function run manually perfectly in the shell. But I want it to be called each time when I add books into a cart. cart/model.py: class BooksInCartManager(models.Manager): def update_cart_book_quantity(self): books = BooksInCart.objects.all() for b in books: b.cart.book_quantity += b.quantity b.cart.save() class Cart(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE, null=True) book_quantity = models.IntegerField(default=0) total_price = models.DecimalField(max_digits=10, decimal_places=2, default=0) def __str__(self): return self.user.email + '_cart' class BooksInCart(models.Model): cart = models.ForeignKey(Cart, on_delete=models.CASCADE) book = models.ForeignKey(Book, on_delete=models.CASCADE) quantity = models.IntegerField(default=1) objects = BooksInCartManager() def __str__(self): return self.book.title On admin site, Cart looks like this: -
Django If Statements not working
So I have been trying to implement a way to create a post where I can upload multiple images with it. I am currently using two forms and two tables, one for the actual post, and one for multiple images associated with it. However, the if statement checking if both forms are valid does not work. It does not post any errors, its just that nothing happens. Nothing gets created nor added to my databases. It doesn't validate even if the forms are complete and correct. I would really appreciate any help ! MY code: views.py class CreateProjectsView(View): def get(self, request): p_photos = P_Images.objects.all() #project_form = ProjectsForm(initial=self.initial) project_form = ProjectsForm() context = { 'p_photos': p_photos, 'project_form': project_form, } return render(self.request, 'projects/forms.html', context) def post(self, request): project_form = ProjectsForm(request.POST, request.FILES) multi_img_form = P_ImageForm(request.POST, request.FILES) if project_form.is_valid() and multi_img_form.is_valid(): instance = project_form.save(commit=False) instance.user = request.user instance.save() images = multi_img_form.save(commit=False) images.save() data = { 'is_valid': True, 'name': images.p_file.name, 'url': images.p_file.url } else: data = { 'is_valid': False, } return JsonResponse(data) basic-upload.js $(function () { /* 1.

DRF create only works if serializer is set to (many=True)
I'm having an issue with a POST request view. DRF will throw an attribute error if I do not set the serializer(AnswerSurveySerializer) to (many=True) but I just want to post a single entry for the field which is a foreignkey.

listen for sensor continuously when using django as a server
I have developed a smart bulb using relay to switch the bulb on and off when I clap. This works with a simple python script but that i want to use django as a server for handling this use case. I could not handle the following cases 1) there will be button for turning the bulb on and off (this i could do) 2) when i clap, the bulb should turn on and again if i clap the bulb should turn off. For second case, how can i continuously listen for the sensor data so my bulb can act it accordingly.

Django migration doesn't recognize abstract base model class changes
I have an abstract model class and its non abstract subclasses. When I run makemigrations for the first time, non abstract subclasses are created without any problem, but when I change the abstract base class, like adding a new field, makemigrations doesn't recognize that non abstract subclasses inherit the changes on their parent class. I have to delete de models, recreate them and run makemigrations. Is there any way for makemigrations to know that the abstract base class has changed and its change must be applied to its subclasses? -
Django REST Framework CurrentUserDefault() with serializer
I have been trying for a while now to add an 'owner' field to my models. I have looked at other questions but I still have had no luck. Ideally when a new note is created, the current user will be set in the owner field and won't be changeable. Below is my model, serializer, and view for a Note as far as I have gotten. I'm guessing the CurrentUserDefault() function needs additional context but I can't set it properly. views.py class NoteListCreateView(ListCreateAPIView): authentication_classes = (SessionAuthentication, TokenAuthentication) permission_classes = (DjangoModelPermissions,) lookup_field = 'pk' serializer_class = serializers.NoteSummarySerializer def get_queryset(self): qs = Note.objects.all() # general search query = self.request.GET.get('search') if query is not None: qs = qs.filter( Q(title__icontains=query) | Q(content__icontains=query) ).distinct() # title search query = self.request.GET.get('title') if query is not None: qs = qs.filter(title__icontains=query) # content search query = self.request.GET.get('content') if query is not None: qs = qs.filter(content__icontains=query) return qs serializers.py class NoteSummarySerializer(serializers.ModelSerializer): owner = serializers.PrimaryKeyRelatedField(default=serializers.CurrentUserDefault(), read_only=True) class Meta: model = Note fields = ( 'pk', 'title', 'containerId', 'created', 'updated', 'owner', ) models.py class Base(models.Model): title = models.CharField(max_length=30) created = models.DateTimeField(auto_now_add=True) updated = models.DateTimeField(auto_now=True) owner = models.ForeignKey(get_user_model(), on_delete=models.CASCADE) class Meta: abstract = True ordering = ['title', '-updated'] class Note(Base): containerId = … -

Handling temporary Django files
I am currently attempting to create a website whereby I can search for product items and the search results would be an aggregation of the search results from different websites. My model looks like this: class Product(models.Model): name = models.CharField(max_length=100) image_file = models.ImageField(upload_to='images/') image_url = models.URLField(max_length=200) url = models.URLField(max_length=200) price = models.CharField(max_length=10) At the moment, my implementation involves scraping the search results from the different pages and extracting the information I need. This includes downloading every single product image from those pages. All of these products are then stored in the database. To prepare for the next search, whenever I enter the "search" page (there is no search bar in the results page), I delete all the contents of my database and also delete the image files I downloaded. def index(request): if Product.objects.all().exists(): Product.objects.all().delete() shutil.rmtree('img directory') #deletes everything in directory return render(request, 'myproject/index.html') This is undoubtedly a terrible way of doing things. What could I do instead to avoid doing this every time? Is there a way for database entries to automatically delete themselves after some amount of time perhaps? Thanks! -

Django GetStream update activity sorting after activity to push it to the top of a feed

When either of this activities takes place, I would like to push this activity to the top of all feeds that are subscribed to the actors feed. I was told that there was no way to update the activity time because the time id pair is the way that GetStream makes activities unique, so I was told to accomplish what we want to accomplish we may remove the activity from the main feed than add it back in with the updated time of the activity I will achieve the desired result. So I have tried to start of by removing the activity from the main feed, as this is vague I assume .. and correct me if im wrong, that it is the actors user feed so this is the code I tried from the console. But first you should see what the timeline looks like from another users feed { currentTimeline(number: 3) { token foreignId time subject { ... on PanelType { author { id username } … -
Code: unknown, Error: Invalid response while obtaining request token from "api.twitter.com" - how to obtain and print Twitter error message
I am using Django Allauth with Django 2.0.8 and 3.5 I have followed the instructions for using Twitter to login to a site. However, when I attempt to login to my website, I am getting the following message: Social Network Login Failure An error occurred while attempting to login via your social network account. There is no log output containing more information - which makes debugging this unnecessarily difficult. Based onan answer for this question, I have added information to my tempate which sheds some more light: Code: {{ auth_error.code }}, Error: {{ auth_error.exception }} However, the error message is: Code: unknown, Error: Invalid response while obtaining request token from "api.twitter.com" Which doesn't help very much. I want to see the actual response returned by the twitter.api, so I can get to the bottom of the problem - however, it is not obvious to me how to output or log the ACTUAL response obtained from the twitter API.
