How to categorize WhiteNoise?
I am writing scientifically about a Django application. The application returns static files via WhiteNoise and I would like to learn more about it to be able to write precise. How is WhiteNoise classified? Is it correct to speak of a middleware? How is the request processed until WhiteNoise comes into play? Is WhiteNoise responsible for providing the correct reference to the static file in the Django template or does it do more? Does the behavior change if the static files are hosted on a CDN? I highly appreciate any input or reference to helpful articles! Thanks in advance. -
How to add multiple reviews or products using for loop in Django? (fetching data)
I need to add multiple reviews using "for loop". I made the model, and then through the admin panel (of Django)added a review. Now within the same code, I need to add another review. I'm pretty new at this and have to follow the instructions and can't do it any other way. This is how I have looped one review: {% for display in Review %} <i><img src="{{display.image}}"/><span>{{display.name}}</span></i> <p>{{display.desc}}</p> {% endfor %} This is the model: class Review(models.Model): image = models.ImageField(upload_to="static/images") name = models.CharField(max_length=20) desc = models.TextField() -

Django-filter issue
I have this problem, so i did a filtering by categories on my AllProducts Page and it worked perfectly (django-filter). The thing is that the startup im working at has another Django Model which is ProductInStore and that's an additional model connected to Product which has to show all the products that a certain shop has. class Product(models.Model): name = models.CharField(max_length=200) slug = models.SlugField(max_length=200, unique=True, null=False, editable=False) created_at = models.DateTimeField(editable=False, default=timezone.now) updated_at = models.DateTimeField(default=timezone.now) product_category = models.ManyToManyField(EcommerceProductCategory) description = RichTextField(max_length=2000, null=True, blank=True) product_producer = models.ForeignKey('ProductProducer', on_delete=models.CASCADE) creator = models.ForeignKey('users.CustomUser', on_delete=models.CASCADE, null=True, blank=True, related_name='product_creator') points_from_reviews = models.DecimalField(max_digits=6, decimal_places=2, default=0, help_text='Średnia ocena produktu') unique_id = models.CharField(max_length=256, unique=True) type_of_unique_id = models.CharField(max_length=64) product_img = models.FileField(upload_to='ecommerce_product_img/', null=True, blank=True) class ProductInStore(models.Model): product = models.ForeignKey('Product', on_delete=models.CASCADE) store = models.ForeignKey('Store', on_delete=models.CASCADE) price = models.DecimalField(max_digits=6, decimal_places=2, default=0, help_text='Cena w sklepie') currency = models.CharField(max_length=4) url = models.CharField(max_length=200) created_at = models.DateTimeField(editable=False, default=timezone.now) updated_at = models.DateTimeField(default=timezone.now) The thing is that when im filtering by categories in Product model it works flawlessly and here's how it looks with Product Model def all_products(request): product = Product.objects.all().order_by('-created_at') search_filter = ProductFilter(request.GET) product = search_filter.qs paginator = Paginator(product, 20) page_number = request.GET.get('page') page_obj = paginator.get_page(page_number) context = { 'page_obj': page_obj, 'search_filter': search_filter, } return render(request, 'ecommerce/all_products.html', context) … -

Django user is_staff field set to true in instance but reads false in permission class
I am trying to create an api endpoint that lists all the users in the database, but I only want staff members to be able to do this. By default when a secretary is created, the is_staff field in the users model is set to True. In the permission class, I am checking to see if this field is set to true and grant permissions accordingly. Since I have many different types of users with slightly different attributes, I created a concrete base user model that is inherited by other user models. The SECRETARY role is assigned by the serializer when handling the secretary creation endpoint request. class User(AbstractBaseUser): class Roles(models.TextChoices): """define the user roles""" ADMIN = "ADMIN", "Admin" PRINTER = "PRINTER", "Printer" SECRETARY = "SECRETARY", "Secretary" PHOTOGRAPHER = "PHOTOGRAPHER", "Photographer" EDITOR = "EDITOR", "Editor" CLIENT = "CLIENT", "Client" SYSTEM = "SYSTEM", "System" APPLICANT = "APPLICANT", "Applicant" id = models.CharField( max_length=8, unique=True, primary_key=True, default=uidgen, editable=False ) first_name = models.CharField("First Name", max_length=30, null=False) last_name = models.CharField("Last Name", max_length=30, null=True, blank=True) email = models.EmailField( verbose_name="Email", max_length=255, unique=True, null=False ) username = None phone_number = models.CharField( "Phone Number", max_length=20, null=False, unique=True ) dob = models.DateField(verbose_name="Date Of Birth", blank=True, null=True) role = models.CharField(max_length=50, default=Roles.CLIENT) … -
Why is my forms content showing in the title for my edit function? Django
I am currently doing an assignment where one of the requirements for the edit function is that the user should be able to click on an edit button and be taken to a page where they have the option of editing what they wrote before. The issue I am having is that I am using INITIAL to push the previously populated content so that it will show, but this keeps showing on the title of the page instead of inside the textarea content. I have tried to tweak this but after several attempts, I keep getting the same issue, when i submit this, it gives me a new entry/page when what I want to do is edit the page and not create a new page. VIEWS.PY class AddPageForm(forms.Form): title = forms.CharField() content = forms.CharField(widget=forms.Textarea( attrs={ "class": "form-control", }) ) def edit_page(request, title): if request.method == "GET": title = title content = util.get_entry(title) form = AddPageForm({"title": title, "content": content}) return render( request, "encyclopedia/editpage.html", {"form": form, "title": title} ) form = AddPageForm(request.POST) if form.is_valid(): title = form.cleaned_data.get("title") content = form.cleaned_data.get("content") util.save_entry(title=title, content=content) return redirect('encyclopedia:entrypage', title) EDIT PAGE {% block body %} <h1>Edit</h1> <form action="{% url 'encyclopedia:editpage' title %}" method="post"> {% csrf_token %} … -

Provide short_description for model field in Django Admin
Sometimes I want to display many boolean fields in the list_display view in Django Admin. Unfortunately these fields come with a long verbose_name which gives very ugly and large columns. I know that you can provide a short_description attribute to callables for providing column names in the list_display view in Django Admin. So I reverted to doing this: class MyModelAdmin(admin.ModelAdmin): list_display = ['id', 'field1', 'field2', 'short_boolfield3', 'short_boolfield4'] def short_boolfield3(self, obj): return obj.boolfield3 short_boolfield3.short_description = 'fld3' short_boolfield3.boolean = True def short_boolfield4(self, obj): return obj.boolfield4 short_boolfield4.short_description = 'fld4' short_boolfield4.boolean = True Which works, but is definitely against DRY, especially when you have many boolean fields. Is there a short_description equivalent for Model fields? -
