Question

我正在尝试根据详细视图中的主键过滤对象。有没有办法可以在我的views.py或其他方式调用我的主键，我可以相应地过滤？这是我的代码：

models.py

class Accounts(models.Model):
    account_name = models.CharField(max_length=50)
    pricing_id = models.ForeignKey('Pricing')

class OrderRecords(models.Model):
    order_id = models.ForeignKey('Orders')
    account_id = models.ForeignKey('Accounts')
    item_id = models.ForeignKey('Items')

views.py

class AccountDetailView(generic.DetailView):
    model = Accounts

    template_name = "orders/accountdetail.html"

    def get_context_data(self, **kwargs):
        context = super(AccountDetailView, self).get_context_data(**kwargs)
        context['orderrecords'] = OrderRecords.objects.filter(????????)
        return context

更新

所以这就是我所做的改变：

views.py

class AccountDetailView(generic.DetailView):
    model = Accounts

    template_name = "orders/accountdetail.html"

    def get_context_data(self, **kwargs):

        pk = self.kwargs['pk']

        context = super(AccountDetailView, self).get_context_data(**kwargs)
        context['orderrecords'] = OrderRecords.objects.filter(account_id=pk)
        return context

是的，在您的观看中，只需致电：

def get_context_data(self, **kwargs):
    pk = kwargs.get('pk') # this is the primary key from your URL
    # your other code
    context = super(AccountDetailView, self).get_context_data(**kwargs)
    context['orderrecords'] = OrderRecords.objects.filter(????????)
    return context
