Can you show how to sort the goods in the online store? So that you can click on the button and the sorting has changed, for example: price,-price. And to views.py was in class, not in def.
views.py
class SectionView(View):
def get(self, request, *args, **kwargs):
sort_form = request.GET.getlist('sort')
products = Product.objects.filter(available=True)
if sort_form.is_valid():
needed_sort = sort_form.cleaned_data.get("sort_form")
if needed_sort == "ДТ":
products = products.order_by(
"created") # или updated в зависимости от того, что ты вкладываешь в понятие по дате
elif needed_sort == "ДЕД":
products = products.order_by("price")
elif needed_sort == "ДОД":
products = products.order_by("-price")
return render(
request=request,
template_name='main/index.html',
context={
'products':products,
}
)
form.py
class SortForm(forms.Form):
sort_form = forms.TypedChoiceField(label='Сортировать:', choices=[('ПУ', 'По умолчанию'), ('ДТ', 'По дате'), ('ДЕД', 'От дешевых к дорогим'), ('ДОД', 'От дорогих к дешевым')])

Answer 1

You can try something like that:
def get(self, request)
allowed_orderings = ('price', '-price', ...) # define orderings you want
ordering = request.GET.get('ordering', '-price') # get ordering from url params
ordering = ordering if ordering in allowed_orderings else '-price' # check ordering is allowed, if not - set the default
your_model = Model.objects.filter(...).order_by(ordering) # filter queryset with your params and then order by defined ordering
... # and then return your models as you want to
For this code you need to provide ordering in your url params (like /shop/goods/?ordering=-price)
