GROUP By in Django ORM for page in Django Admin
I'm not very long in Django, sorry for the probably stupid question. But after many hours of trying to solve and a huge number of searches on the Internet, I did not find a solution. My Models: class Offer(models.Model): seller = models.ForeignKey()<..> # other fields class OfferViewCount(models.Model): offer = models.ForeignKey(Offer, verbose_name=_('Offer'), on_delete=models.CASCADE) user_agent = models.CharField(verbose_name=_('User Agent'), max_length=200) ip_address = models.CharField(verbose_name=_('IP Address'), max_length=32) created_date = models.DateTimeField(auto_now_add=True) The database of the OfferViewCount model has the following data: id;user_agent;ip_address;created_date;offer_id 24;insomnia/2022.6.0f;127.0.0.1;2022-11-18 14:14:52.501008+00;192 25;insomnia/2022.6.0z;127.0.0.1;2022-11-18 15:03:31.471366+00;192 23;insomnia/2022.6.0;127.0.0.1;2022-11-18 14:14:49.840141+00;193 28;insomnia/2022.6.0;127.0.0.1;2022-11-18 15:04:18.867051+00;195 29;insomnia/2022.6.0;127.0.0.1;2022-11-21 11:33:15.719524+00;195 30;test;127.0.1.1;2022-11-22 19:34:39+00;195 If I use the default output in Django Admin like this: class OfferViewCountAdmin(admin.ModelAdmin): list_display = ('offer',) I get this: Offer offer #192 offer #192 offer #193 offer #195 offer #195 offer #195 I want to get a result like this: Offer;Views offer #192;2 offer #193;1 offer #195;3 Simply put, I want to display one instance of each duplicate post in the admin, and display the total number of them in a custom field. In SQL it would look something like this: SELECT offer_id, COUNT(*) AS count FROM offer_offerviewcount GROUP BY offer_id ORDER BY COUNT DESC; I've tried many options, including overwriting get_queryset.

How to use transaction with "async" functions in Django?
When async def call_test(request): called async def test(): as shown below (I use Django==3.1.7): async def test(): for _ in range(0, 3): print("Test") async def call_test(request): await test() # Here return HttpResponse("Call_test") There was no error displaying the proper result below on console: Test Test Test But, when I put @transaction.atomic() on async def test(): as shown below: @transaction.atomic() # Here async def test(): for _ in range(0, 3): print("Test") # ... The error below occurred: django.core.exceptions.SynchronousOnlyOperation: You cannot call this from an async context - use a thread or sync_to_async. So, I put @sync_to_async on @transaction.atomic() as shown below: @sync_to_async # Here @transaction.atomic() async def test(): for _ in range(0, 3): print("Test") # ... But other error below occurred: RuntimeWarning: coroutine 'test' was never awaited handle = None # Needed to break cycles when an exception occurs. RuntimeWarning: Enable tracemalloc to get the object allocation traceback So, how can I use transaction with "async" functions in Django? -
Pagination doesn`t work with extra context in Django ListView
I am trying to create a simple pagination through a query of filtered instances of Need model. The problem is that pagination doesn`t work at all, and I guess this is because of extra content. Here is my current view, which shows pagination on front-end as an empty div: class CategoryNeeds(ListView): model = Need template_name = "volunteering/category_needs.html" paginate_by = 1 context_object_name = "needs" def get_queryset(self): return Need.objects.filter(category__name=self.kwargs["name"].capitalize()) def get(self, request, *args, **kwargs): self.object_list = self.get_queryset() category = Category.objects.get(name=kwargs["name"].capitalize()) self.extra_context = { "category": category, "needs": self.object_list } return self.render_to_response(self.extra_context) And here is the template: {% extends "index/index.html" %} {% block content %} <section class="contact-section bg-black"> <div class="container px-4 px-lg-5"> <div class="row gx-4 gx-lg-5"> <div class="col-md-4 mb-3 mb-md-0"> <div class="card-body text-center"> <h1>{{ category.name }}</h1> <hr style="size: A5"> </div> </div> </div> </div> </section> <section class="about-section text-center" id="about"> <div class="container px-4 px-lg-5"> <h2>Needs:</h2> <table class="table table-dark table-striped"> <thead> <tr> <th scope="col">Photo</th> <th scope="col">Title</th> <th scope="col">Description</th> <th scope="col">Price</th> <th scope="col">Donation</th> <th scope="col">City</th> {% if user.pk == user_page.pk %} <th scope="col">Update</th> <th scope="col">Delete</th> {% endif %} </tr> </thead> <tbody> {% for need in needs %} <tr data-href="{% url "volunteering:need" need.pk %}"> <td>{% if need.photo %}<img src="{{ need.photo.url }}">{% endif %}</td> <td>{{ need.title }}</td> <td>{{ need.description|truncatechars:10 }}</td> … -
Why do I get 404 error when calling Ajax Load Function in Django?
I am building a page in Django that first renders a blank page with a loading picture, and then calls an Ajax get function to one of my views. Once my Ajax get function succeeds, it is supposed to load one of my HTML files. I get a 404 error saying that the template cannot be found, but the template is in the same folder as my other file. Is my file path wrong? <head> <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script> </head> {% extends "stocks_sites/base.html" %} <!-- The loading image --> {% block loader %} <div id="loading"> <p>Loading</p> </div> <div id="articles"> </div> <script> // AJAX call when page has loaded $(document).ready(function(){ $.ajax({ type: "GET", url: "{% url 'stocks_sites:get_news_articles' %}", success: function(response) { const news_articles = response; const posts = news_articles.posts; const search = news_articles.search; document.getElementById("loading").style.display = "none"; $("#articles").load("news_articles.html"); } }); }); </script> {% endblock loader %} -

How to write dynamic Django URL's to capture data and pass to a view for processing
So I am writing a simple website with Django, with some basic CRUD features. The website has 7 main models in total. Contact Details Personal Details Mobile Provider Details TV Provider Details Broadband Provider Details Internet Provider Details User Consent The way I have wrote the website, I have created a URL path for each model, each with a Create, Update and Delete action (see below snippet) path('addcontactdetails', views.addContactDetail, name='addcontactdetails'), path('updatecontactdetails', views.updateContactDetail, name='updatecontactdetails'), path('deletecontactdetails', views.deleteContactDetail, name='deletecontactdetails'), For each URL path, I have then created corresponding views to process the requests (see below snippet from addContactDetail view). @login_required(login_url='login') def addContactDetail(request): data_to_capture = 'Contact Details' form = ContactDetailForm() if request.method == 'POST': form = ContactDetailForm(request.POST) current_user = request.user ContactDetail.objects.create( user = current_user, user_email = request.POST.get('user_email'), mobile_phone_no = request.POST.get('mobile_phone_no'), door_no_or_house_name = request.POST.get('door_no_or_house_name'), address_line_1 = request.POST.get('address_line_1'), address_line_2 = request.POST.get('address_line_2'), town_or_city = request.POST.get('town_or_city'), post_code = request.POST.get('post_code'), ) return redirect('profile') context = { 'data_to_capture': data_to_capture, 'form': form } return render(request, 'base/capture_data.html', context) I am wondering if there is a more sophisticated way to write my URL paths, so that I can reduce the number of URL paths I need, and limit the number of views I need. I would have though there would be a way … -
Trying to save multiple files to a model referencing another model

How do I exclude 'self' instance from a ManyToMany field which references the 'self' model?
I have a 'Pizza' model that can inherit 'Toppings' from another instance of 'Pizza'. When I go to update the Pizza, to add new toppings, I need to prevent the user from selecting the 'self' instance of Pizza in the parent list. For Example: I create Margarita pizza with cheese and tomato toppings. I then create another Pizza (Pepperoni) and inherit all toppings form the Margarita. I need to stop Pepperoni from appearing in the 'parents' list to stop a circular reference. models.py class Topping(models.Model): name = models.CharField(max_length=100) class Pizza(models.Model): name = models.CharField(max_length=100) parents = models.ManyToManyField("self", symmetrical=False) toppings = models.ManyToManyField(Topping) forms.py class PizzaForm(ModelForm): toppings = forms.ModelMultipleChoiceField( queryset=Topping.objects.all(), widget=forms.CheckboxSelectMultiple, required=False ) parents = forms.ModelMultipleChoiceField( queryset=Pizza.objects.all(), widget=forms.CheckboxSelectMultiple, required=False ) class Meta: model = Pizza fields = '__all__' views.py class PizzaUpdateView(UpdateView): model = Pizza form_class = PizzaForm I suspect I need to amend the parent queryset in PizzaForm to exclude a PK, but I'm unsure of how to hand this through to the form from my view. -

How to get a QuerySet with values of a specific field in Django while maintaining the order?

I want to implement it using only Django ORM query without using for loop. preserved = Case(*[When(name=name, then=pos) for pos, name in enumerate(book_names)]) Book.objects.filter(name__in=book_names).order_by(preserved) # >>> [Book(name='C'), Book(name='A'), Book(name='B')] In this way, I can get list of objects in the same order, but I don't know how to get None when the value doesn't exist. -

Django ValueError: Cannot assign "<SimpleLazyObject: <CustomUser: >>": "Booking.user" must be a "Customer" instance
The objective is simple: I'm building a car rental platform where customers can place an order for a car. The simple 'order' contains the car, start, and end-dates. The form should automatically save the authenticated user as the creator. It uses a CreateView with this code: class BookingCreate(CreateView): model = Booking fields = ['car', 'start_date', 'end_date'] permission_classes = [permissions.IsAuthenticated] def form_valid(self, form): form.instance.user = self.request.user return super().form_valid(form) The form works fine, but when submitted, it raises this error: ValueError at /rentals/booking/create Cannot assign "<SimpleLazyObject: <CustomUser: Test2 Two>>": "Booking.user" must be a "Customer" instance. I've looked up previous answers, and the best solution came from this thread, which recommended using this code instead def form_valid(self, form): form.instance.user = Booking.objects.get(user=self.request.user) return super().form_valid(form) However, this change returns a slightly different error: ValueError at /rentals/booking/create Cannot query "Test2 Two": Must be "Customer" instance. I have a customUser Model and a "customer" model that inherits from it. For additional context, I am using a customUser model. Because I have multiple user types (in particular (car) Owners and Customers), I use a special table with boolean fields to mark each type as True based on the registration form they use per this this tutorial. Here's the … -

Dash Django installation
I want to install django-plotly-dash and I was going step by step as in this installation guide https://django-plotly-dash.readthedocs.io/en/latest/installation.html, however when I do python manage.py migrate I get the following problem: ImportError: cannot import name 'InvalidCallbackReturnValue' from 'dash.exceptions' Did anyone else have the same problem when installing django-plotly-dash?
