在Django中过滤外键

如何解决在Django中过滤外键

我正在尝试过滤外键，但是无论我从示例中使用哪种方法，它都不会呈现任何数据。这是代码

Class Customer（models.Model）：

user = models.OnetoOneField(User,on_delete=models.CASCADE,related_name='customer',primary_key=True)
first_name = models.CharField(blank=True,max_length=150)
last_name = models.CharField(blank=True,max_length=150)
name = models.CharField(max_length=200,null=True)

'

class Order（models.Model）

distributor = models.ManyToManyField(settings.AUTH_USER_MODEL,)
Customer = models.ForeignKey(settings.AUTH_USER_MODEL,on_delete=models.SET_NULL,null=True,related_name='customer_client')

景观

def dashboard(request):
    orders = Order.objects.filter(distributor=request.user)
    customers = orders.filter(Customer_id=1)

模板（摘要）

{% for customer in customers %}
                    <tr>
                        <td><a class="btn btn-sm btn-info" href="{% url 'distributor:customer' customer.user_id %}">View</a></td>
                        <td>{{customer.name}}</td>
                        <td>{{customer.email}}</td>
                    </tr>
                {% endfor %}

我正在尝试过滤从特定分销商下订单的客户，请提供帮助

解决方法

运行上面的代码，让我知道终端的结果，然后我可以帮助您进一步

def dashboard(request):
    orders = Order.objects.filter(Distributor=request.user)
    print(orders)
    customers = orders.filter(Customer_id=1)
    print(customers)

,

尝试一下：

def dashboard(request):
customers = Order.objects.filter(Distributor=request.user,Customer_id=1)
