Python: How to call all objects of a class with their attributes in Django?
For some context, the class is meant to hold the metadata of the products, which are objects. Now, I would like to pass the objects to my template, in order to call its attributes. Here's my code in views.py: def prices(request): @attr.s class ProductMetadata: """ Metadata for a Stripe product. """ stripe_id = attr.ib() name = attr.ib() features: list = attr.ib() monthly_price = attr.ib() yearly_price = attr.ib() standard = ProductMetadata( stripe_id='example', name='Standard', features=[(True ,"Up to 1000 DMs"), (False, "Ludicrous mode"), (False, "Premium Support")], monthly_price = "month1", yearly_price = "year1" ) premium = ProductMetadata( stripe_id='example2', name='Premium', features=[(True ,"Up to 1000 DMs"), (True, "Ludicrous mode"), (False, "Premium Support")], monthly_price = "month2", yearly_price = "year2" ) business = ProductMetadata( stripe_id = "example3", name = 'Business', features=[(True ,"Up to 1000 DMs"), (True, "Ludicrous mode"), (True, "Premium Support")], monthly_price = 'month3', yearly_price = 'year3' ) return render(request, 'instagram_prices.html', {'products': ProductMetadata.all()}) How can I achieve this?

How to store filtered data in excel in Django?
Made a view that pulls data from the model. Based on this data, the table in the template is filled. For each field of the table (model) added filtering based on django-filters. Faced the following problem, I need to save filtered data to excel. The problem is precisely in getting the filtered data, saving in excel is not a problem. My class based view: class RequestList(FilterView): template_name = 'MQueryboard/Requests/RequestList.html' filterset_class = Filter_Adjustments_view model = Adjustments paginate_by = 3 def get_queryset(self): filterset_class = Adjustments.objects.order_by('-dateadjustment') return filterset_class def get_context_data(self, *args, **kwargs): _request_copy = self.request.GET.copy() parameters = _request_copy.pop('page', True) and _request_copy.urlencode() context = super().get_context_data(*args, **kwargs) context['parameters'] = parameters return context def post(self, request): if request.method == 'POST': response = adjustments_to_excel(Adjustments.objects.all()) return response else: return render(request, 'MQueryboard/Requests/RequestList.html', {}) The adjustments_to_excel function - in order not to load the view, data is sent to the script to generate an Excel file. Here I do not understand how I can get the filtered queryset in the post function. Now, as a "stub" is the selection for all fields of the model. Please tell me how you can do this.

Is there a way to create an endpoint (and subsequently view) for a choice field in a Django backend?
In my Django models.py file, I have a variable ColourChoices = ((0, "GREEN"), (1, "YELLOW"), (2, "RED"), (3, "GREY")) where in the same file, ColourChoices is used in class class Rainbow(models.Model): colour = models.IntegerField(choices=ColourChoices) I was wondering if there is a viable way to create a view for ColourChoices (i.e. some JSON endpoint), such that you can get all the existing values for it (GREEN, YELLOW, RED, GREY) without creating a new table in the underlying database and adding those values to it? That is, in such a way that if I were to add a new colour (e.g. BLUE), or remove one colour from the choices, that doing it once in the code would do the trick (i.e. change what you see in the view). -

Django Version: 3.1.6 Python Version: 3.6.9 I'm trying to use the ImageField in my django admin page to upload an image. When I try to upload it from my NGinx/Gunicorn server I get this error. However when I run it from port 8000 using manage.py runserver 0:8000 from the SAME server, it works. I don't understand this error. I have Pillow installed.
