Django Shop-按品牌，价格和其他属性过滤产品形式

Question

我尝试创建在线商店，因此无法同时过滤往返的品牌和价格。

我有一张表格。在模板中有字段（Brands，min_cena和max_cena）的地方，我在左侧有两列，例如在商店的所有站点中的一列中，在另一列中的品牌中，您可以在两个字段中设置价格的往返。相应地，我有两种形式的het方法和两个用于传递参数的按钮。如果在一个按钮下添加品牌和价格字段的输出以提交，则一切正常。但这看起来很难看，我单独将其提供给请求或价格或品牌。

表格

class BrandForms(forms.Form):
    brand = forms.ModelMultipleChoiceField(queryset=Vendor.objects.none(), widget=forms.CheckboxSelectMultiple(), required=False)
    min_price = forms.IntegerField(label='от', required=False)
    max_price = forms.IntegerField(label='до', required=False)

filter_brand = BrandForms(request.GET)
    if filter_brand.is_valid():
        if filter_brand.cleaned_data['brand']:
            print(filter_brand.cleaned_data['brand'])

            list_pro = Product.objects.filter(category__in=Category.objects.get(id=category.id)\
                                               .get_descendants(include_self=True)) \
                                               .annotate(min_price=Min('prices__price'))\
                                               .filter(vendor__in=filter_brand.cleaned_data['brand'])
            products_list = helpers.pg_records(request, list_pro, 12)
    if filter_brand.is_valid():
        if filter_brand.cleaned_data['min_price']:
            list_pro = list_pro.filter(prices__price__gte=filter_brand.cleaned_data['min_price'])
            products_list = helpers.pg_records(request, list_pro, 12)
