Question

我有以下型号：

class Rate(models.Model):
    building = models.ForeignKey(Building, verbose_name="Objekt")
    year = models.IntegerField("Jahr")
    monthly_rate = models.DecimalField("Monatsrate", max_digits=8, decimal_places=2)
    paid = models.DecimalField("Tatsächlich Bezahlt (Brutto)", max_digits=8, decimal_places=2, blank=True, null=True)

class Building(models.Model):
    customer = models.ForeignKey(Customer, verbose_name="Kunde")
    ...
    billing_begin = models.DateField("Abrechnungsbeginn")

class Bank(models.Model):
    name = models.CharField("Bankname", max_length=64) #Bankname
    account_number = models.IntegerField("Kontonummer") #Kontonummer
    code_number = models.IntegerField("Bankleitzahl") #Bankleitzahl
    IBAN = models.CharField(max_length=32)
    BIC = models.CharField(max_length=32)

class Customer(models.Model):
    bank = models.ForeignKey(Bank)

现在我有以下观点：

class BuildingRateListView(ListView):
    model = Building
    template_name = "Building/building_bank_list.html"

    def get_context_data(self, **kwargs):
        context = super(BuildingRateListView, self).get_context_data(**kwargs)
        buildings = Building.objects.filter(customer__debitor=True).order_by('customer__bank', 'customer__last_name')

    erg = []
    for b in buildings:
        rate = str(b.rate_set.latest('year')) + "€"
        erg.append(rate)

    context['building_list'] = erg
    banklist = []
    for b in Bank.objects.all():
        bank_list.append(b)
        #some other code here

    context['bank_list'] = bank_list
    return context

在我的模板中，我有一份建筑物清单和一份包含银行清单的下拉列表。在下拉列表中，我想选择一个银行并仅显示那些客户拥有所选银行的建筑物。作为初学者，我不知道如何进行这种动态查询。如何在我的view.py，urls.py和template.html中编写？

使用下拉菜单进行动态过滤
