Django如何使用函数return设置基于类的视图查询集

我试图用过滤后的数据进行无休止的分页,并用get请求获取数据。

意见。py:

class ProductsView(ListView):
    
    paginate_by = 20
    context_object_name = 'products'
    template_name = "urunler.html"
    def get_context_data(self, **kwargs):
        context = super().get_context_data(**kwargs)
        renkler = Renk.objects.all()
        beden = Varyasyon.objects.all()
        katagori = Grub.objects.all()
        order = self.request.GET.get('order')
        filtered = Stok.objects.all().order_by('-urun_id__kayit_tarihi','foto').distinct('urun_id__kayit_tarihi','foto')
        checked_var = self.request.GET.getlist('varyasyon_id__in')
        checked_renk = self.request.GET.getlist('renk_id__in')
        checked_kat = self.request.GET.getlist('grub_id__in')
        if self.request.GET.getlist("varyasyon_id__in"):
            filtered = filtered.filter(
                Q(varyasyon_id__in = self.request.GET.getlist("varyasyon_id__in"))
            )
        if self.request.GET.getlist("renk_id__in"):
            filtered = filtered.filter(
                Q(renk_id__in = self.request.GET.getlist("renk_id__in"))
            )
        if self.request.GET.getlist("grub_id__in"):
            filtered = filtered.filter(
                Q(grub_id__in = self.request.GET.getlist("grub_id__in"))
            )
        
        if order == "date":
            filters = filtered.filter(
            Q(urun_id__yayin = True) & Q(stok_adet__gt = 0)
        )
        elif order == "sale":
            filters = filtered.filter(
            Q(urun_id__yayin = True) & Q(stok_adet__gt = 0) & Q(indirim = True)
        )
        elif order == "tesettur":
            filters = filtered.filter(
            Q(urun_id__yayin = True) & Q(stok_adet__gt = 0) & Q(urun_id__tesettur = True)
        )
        else:
            filters = filtered.filter(
            Q(urun_id__yayin = True) & Q(stok_adet__gt = 0)
        )
        
        context = {"renkler":renkler,"bedenler":beden,"katagoriler":katagori,'filtered':filters,'checkedvar':checked_var,'checkedrenk':checked_renk,'checkedkat':checked_kat}
        self.queryset = context
        return context
    queryset = get_context_data()

我想从get_context_数据的返回中设置queryset,但它要求自变量。

错误

TypeError: ProductsView.get_context_data() missing 1 required positional argument: 'self'

当我在顶部定义queryset时,它说get_context_数据没有定义。
